Problem:

Certain Insights Advisor features differentiate between RHEL and OCP advisor

Goal:

Address top priority UI misalignments between RHEL and OCP advisor. Address UI features dropped from Insights ADvisor for OCP GA.

Scope:

Specific tasks and priority of them tracked in https://issues.redhat.com/browse/CCXDEV-7432

Managing PVs at scale for a fleet creates difficulties where "one size does not fit all". The ability for SRE to deploy prometheus with PVs and have retention based an on a desired size would enable easier management of these volumes across the fleet. 

The prometheus-operator exposes retentionSize.

This is a feature request to enable this configuration option via CMO cluster-monitoring-config ConfigMap.

Problem Alignment

The Problem

Today, all configuration for setting individual, for example, routing configuration is done via a single configuration file that only admins have access to. If an environment uses multiple tenants and each tenant, for example, has different systems that they are using to notify teams in case of an issue, then someone needs to file a request w/ an admin to add the required settings.

That can be bothersome for individual teams, since requests like that usually disappear in the backlog of an administrator. At the same time, administrators might get tons of requests that they have to look at and prioritize, which takes them away from more crucial work.

We would like to introduce a more self service approach whereas individual teams can create their own configuration for their needs w/o the administrators involvement.

Last but not least, since Monitoring is deployed as a Core service of OpenShift there are multiple restrictions that the SRE team has to apply to all OSD and ROSA clusters. One restriction is the ability for customers to use the central Alertmanager that is owned and managed by the SRE team. They can't give access to the central managed secret due to security concerns so that users can add their own routing information.

High-Level Approach

Provide a new API (based on the Operator CRD approach) as part of the Prometheus Operator that allows creating a subset of the Alertmanager configuration without touching the central Alertmanager configuration file.

Please note that we do not plan to support additional individual webhooks with this work. Customers will need to deploy their own version of the third party webhooks.

Goal & Success

• Allow users to deploy individual configurations that allow setting up Alertmanager for their needs without an administrator.

Solution Alignment

Key Capabilities

• As an OpenShift administrator, I want to control who can CRUD individual configuration so that I can make sure that any unknown third person can touch the central Alertmanager instance shipped within OpenShift Monitoring.
• As a team owner, I want to deploy a routing configuration to push notifications for alerts to my system of choice.

Key Flows

Team A wants to send all their important notifications to a specific Slack channel.

• Administrator gives permission to Team A to allow creating a new configuration CR in their individual namespace.
• Team A creates a new configuration CR.
• Team A configures what alerts should go into their Slack channel.
• Open Questions & Key Decisions (optional)
• Do we want to improve anything inside the developer console to allow configuration?

Which service is this feature request for?
OpenShift Dedicated and Red Hat OpenShift Service on AWS

What are you trying to do?
Allow ROSA/OSD to integrate with AWS Managed Prometheus.

Describe the solution you'd like
Remote-write of metrics is supported in OpenShift but it does not work with AWS Managed Prometheus since AWS Managed Prometheus requires AWS SigV4 auth.

• Note that Prometheus supports AWS SigV4 since v2.26 and OpenShift 4.9 uses v2.29.

Describe alternatives you've considered
There is the workaround to use the "AWS SigV4 Proxy" but I'd think this is not properly supported by RH.
https://mobb.ninja/docs/rosa/cluster-metrics-to-aws-prometheus/

Additional context
The customer wants to use an open and portable solution to centralize metrics storage and analysis. If they also deploy to other clouds, they don't want to have to re-configure. Since most clouds offer a Prometheus service (or it's easy to self-manage Prometheus), app migration should be simplified.

OCP/Telco Definition of Done
Feature Template descriptions and documentation.

Feature Overview.

Early customer feedback is that they see SNO as a great solution covering smaller footprint deployment, but are wondering what is the evolution story OpenShift is going to provide where more capacity or high availability are needed in the future.

While migration tooling (moving workload/config to new cluster) could be a mid-term solution, customer desire is not to include extra hardware to be involved in this process.

 For Telecommunications Providers, at the Far Edge they intend to start small and then grow. Many of these operators will start with a SNO-based DU deployment as an initial investment, but as DUs evolve, different segments of the radio spectrum are added, various radio hardware is provisioned and features delivered to the Far Edge, the Telecommunication Providers desire the ability for their Far Edge deployments to scale up from 1 node to 2 nodes to n nodes. On the opposite side of the spectrum from SNO is MMIMO where there is a robust cluster and workloads use HPA.

Goals

• Provide the capability to expand a single replica control plane topology to host more workloads capacity - add worker
• Provide the capability to expand a single replica control plane to be a highly available control plane
• To satisfy MMIMO Telecommunications providers will want the ability to scale a SNO to a multi-node cluster that can support HPA.
• Telecommunications providers do not want workload (DU specifically) downtime when migrating from SNO to a multi-node cluster.
• Telecommunications providers wish to be able to scale from one to two or more nodes to support a variety of radio hardware.
• Support CP scaling (CP HA) for 2 node cluster, 3 node cluster and n node cluster. As the number of nodes in the cluster increases so does the failure domain of the cluster. The cluster is now supporting more cell sectors and therefore has more of a need for HA and resiliency including the cluster CP.

Feature Overview

• As an infrastructure owner, I want a repeatable method to quickly deploy the initial OpenShift cluster.

• As an infrastructure owner, I want to install the first (management, hub, “cluster 0”) cluster to manage other (standalone, hub, spoke, hub of hubs) clusters.

Goals

• Enable customers and partners to successfully deploy a single “first” cluster in disconnected, on-premises settings

Requirements

4.11 MVP Requirements

• Customers and partners needs to be able to download the installer
• Enable customers and partners to deploy a single “first” cluster (cluster 0) using single node, compact, or highly available topologies in disconnected, on-premises settings
• Installer must support advanced network settings such as static IP assignments, VLANs and NIC bonding for on-premises metal use cases, as well as DHCP and PXE provisioning environments.
• Installer needs to support automation, including integration with third-party deployment tools, as well as user-driven deployments.
• In the MVP automation has higher priority than interactive, user-driven deployments.
• For bare metal deployments, we cannot assume that users will provide us the credentials to manage hosts via their BMCs.
• Installer should prioritize support for platforms None, baremetal, and VMware.
• The installer will focus on a single version of OpenShift, and a different build artifact will be produced for each different version.
• The installer must not depend on a connected registry; however, the installer can optionally use a previously mirrored registry within the disconnected environment.

Use Cases

• As a Telco partner engineer (Site Engineer, Specialist, Field Engineer), I want to deploy an OpenShift cluster in production with limited or no additional hardware and don’t intend to deploy more OpenShift clusters [Isolated edge experience].
• As a Enterprise infrastructure owner, I want to manage the lifecycle of multiple clusters in 1 or more sites by first installing the first  (management, hub, “cluster 0”) cluster to manage other (standalone, hub, spoke, hub of hubs) clusters [Cluster before your cluster].
• As a Partner, I want to package OpenShift for large scale and/or distributed topology with my own software and/or hardware solution.
• As a large enterprise customer or Service Provider, I want to install a “HyperShift Tugboat” OpenShift cluster in order to offer a hosted OpenShift control plane at scale to my consumers (DevOps Engineers, tenants) that allows for fleet-level provisioning for low CAPEX and OPEX, much like AKS or GKE [Hypershift].
• As a new, novice to intermediate user (Enterprise Admin/Consumer, Telco Partner integrator, RH Solution Architect), I want to quickly deploy a small OpenShift cluster for Poc/Demo/Research purposes.

Questions to answer…

Out of Scope

Out of scope use cases (that are part of the Kubeframe/factory project):

• As a Partner (OEMs, ISVs), I want to install and pre-configure OpenShift with my hardware/software in my disconnected factory, while allowing further (minimal) reconfiguration of a subset of capabilities later at a different site by different set of users (end customer) [Embedded OpenShift].
• As an Infrastructure Admin at an Enterprise customer with multiple remote sites, I want to pre-provision OpenShift centrally prior to shipping and activating the clusters in remote sites.

Background, and strategic fit

• This Section: What does the person writing code, testing, documenting need to know? What context can be provided to frame this feature.

Assumptions

1. The user has only access to the target nodes that will form the cluster and will boot them with the image presented locally via a USB stick. This scenario is common in sites with restricted access such as government infra where only users with security clearance can interact with the installation, where software is allowed to enter in the premises (in a USB, DVD, SD card, etc.) but never allowed to come back out. Users can't enter supporting devices such as laptops or phones.
2. The user has access to the target nodes remotely to their BMCs (e.g. iDrac, iLo) and can map an image as virtual media from their computer. This scenario is common in data centers where the customer provides network access to the BMCs of the target nodes.
3. We cannot assume that we will have access to a computer to run an installer or installer helper software.

Feature Overview

The AWS-specific code added in OCPPLAN-6006 needs to become GA and with this we want to introduce a couple of Day2 improvements.
Currently the AWS tags are defined and applied at installation time only and saved in the infrastructure CRD's status field for further operator use, which in turn just add the tags during creation.

Saving in the status field means it's not included in Velero backups, which is a crucial feature for customers and Day2.
Thus the status.resourceTags field should be deprecated in favour of a newly created spec.resourceTags with the same content. The installer should only populate the spec, consumers of the infrastructure CRD must favour the spec over the status definition if both are supplied, otherwise the status should be honored and a warning shall be issued.

Being part of the spec, the behaviour should also tag existing resources that do not have the tags yet and once the tags in the infrastructure CRD are changed all the AWS resources should be updated accordingly.

On AWS this can be done without re-creating any resources (the behaviour is basically an upsert by tag key) and is possible without service interruption as it is a metadata operation.

Tag deletes continue to be out of scope, as the customer can still have custom tags applied to the resources that we do not want to delete.

Due to the ongoing intree/out of tree split on the cloud and CSI providers, this should not apply to clusters with intree providers (!= "external").

Once confident we have all components updated, we should introduce an end2end test that makes sure we never create resources that are untagged.

After that, we can remove the experimental flag and make this a GA feature.

Goals

• Inclusion in the cluster backups
• Flexibility of changing tags during cluster lifetime, without recreating the whole cluster

Requirements

• This Section:* A list of specific needs or objectives that a Feature must deliver to satisfy the Feature.. Some requirements will be flagged as MVP. If an MVP gets shifted, the feature shifts. If a non MVP requirement slips, it does not shift the feature.

Feature Overview  

Much like core OpenShift operators, a standardized flow exists for OLM-managed operators to interact with the cluster in a specific way to leverage AWS STS authorization when using AWS APIs as opposed to insecure static, long-lived credentials. OLM-managed operators can implement integration with the CloudCredentialOperator in well-defined way to support this flow.

Goals:

Enable customers to easily leverage OpenShift's capabilities around AWS STS with layered products, for increased security posture. Enable OLM-managed operators to implement support for this in well-defined pattern.

Requirements:

• CCO gets a new mode in which it can reconcile STS credential request for OLM-managed operators
• A standardized flow is leveraged to guide users in discovering and preparing their AWS IAM policies and roles with permissions that are required for OLM-managed operators 
• A standardized flow is defined in which users can configure OLM-managed operators to leverage AWS STS
• An example operator is used to demonstrate the end2end functionality
• Clear instructions and documentation for operator development teams to implement the required interaction with the CloudCredentialOperator to support this flow

Use Cases:

See Operators & STS slide deck.

Out of Scope:

• handling OLM-managed operator updates in which AWS IAM permission requirements might change from one version to another (which requires user awareness and intervention)

Background:

The CloudCredentialsOperator already provides a powerful API for OpenShift's cluster core operator to request credentials and acquire them via short-lived tokens. This capability should be expanded to OLM-managed operators, specifically to Red Hat layered products that interact with AWS APIs. The process today is cumbersome to none-existent based on the operator in question and seen as an adoption blocker of OpenShift on AWS.

Customer Considerations

This is particularly important for ROSA customers. Customers are expected to be asked to pre-create the required IAM roles outside of OpenShift, which is deemed acceptable.

Documentation Considerations

• Internal documentation needs to exists to guide Red Hat operator developer teams on the requirements and proposed implementation of integration with CCO and the proposed flow
• External documentation needs to exist to guide users on:
  • how to become aware that the cluster is in STS mode
  • how to become aware of operators that support STS and the proposed CCO flow
  • how to become aware of the IAM permissions requirements of these operators
  • how to configure an operator in the proposed flow to interact with CCO

Interoperability Considerations

• this needs to work with ROSA
• this needs to work with self-managed OCP on AWS

Feature Overview

Customers are asking for improvements to the upgrade experience (both over-the-air and disconnected). This is a feature tracking epics required to get that work done.  

Goals

1. Have an option to do upgrades in more discrete steps under admin control. Specifically, these steps are: 
   • Control plane upgrade
   • Worker nodes upgrade
   • Workload enabling upgrade (i..e. Router, other components) or infra nodes
2. Better visibility into any errors during the upgrades and documentation of what they error means and how to recover. 
3. An user experience around an end-2-end back-up and restore after a failed upgrade 
4. OTA-810  - Better Documentation: 
   • Backup procedures before upgrades. 
   • More control over worker upgrades (with tagged pools between user Vs admin)
   • The kinds of pre-upgrade tests that are run, the errors that are flagged and what they mean and how to address them. 
   • Better explanation of each discrete step in upgrades, and what each CVO Operator is doing and potential errors, troubleshooting and mitigating actions.

tldr: three basic claims, the rest is explanation and one example

1. We cannot improve long term maintainability solely by fixing bugs.
2. Teams should be asked to produce designs for improving maintainability/debugability.
3. Specific maintenance items (or investigation of maintenance items), should be placed into planning as peer to PM requests and explicitly prioritized against them.

While bugs are an important metric, fixing bugs is different than investing in maintainability and debugability. Investing in fixing bugs will help alleviate immediate problems, but doesn't improve the ability to address future problems. You (may) get a code base with fewer bugs, but when you add a new feature, it will still be hard to debug problems and interactions. This pushes a code base towards stagnation where it gets harder and harder to add features.

One alternative is to ask teams to produce ideas for how they would improve future maintainability and debugability instead of focusing on immediate bugs. This would produce designs that make problem determination, bug resolution, and future feature additions faster over time.

I have a concrete example of one such outcome of focusing on bugs vs quality. We have resolved many bugs about communication failures with ingress by finding problems with point-to-point network communication. We have fixed the individual bugs, but have not improved the code for future debugging. In so doing, we chase many hard to diagnose problem across the stack. The alternative is to create a point-to-point network connectivity capability. this would immediately improve bug resolution and stability (detection) for kuryr, ovs, legacy sdn, network-edge, kube-apiserver, openshift-apiserver, authentication, and console. Bug fixing does not produce the same impact.

We need more investment in our future selves. Saying, "teams should reserve this" doesn't seem to be universally effective. Perhaps an approach that directly asks for designs and impacts and then follows up by placing the items directly in planning and prioritizing against PM feature requests would give teams the confidence to invest in these areas and give broad exposure to systemic problems.

Background, and strategic fit

Consumption of RHEL entitlements has been a challenge on OCP 4 since it moved to a cluster-based entitlement model compared to the node-based (RHEL subscription manager) entitlement mode. In order to provide a sufficiently similar experience to OCP 3, the entitlement certificates that are made available on the cluster (OCPBU-93) should be shared across namespaces in order to prevent the need for cluster admin to copy these entitlements in each namespace which leads to additional operational challenges for updating and refreshing them.

Epic Goal

HyperShift provisions OpenShift clusters with externally managed control-planes. It follows a slightly different process for provisioning clusters. For example, HyperShift uses cluster API as a backend and moves all the machine management bits to the management cluster.  

Why is this important?

showing machine management/cluster auto-scaling tabs in the console is likely to confuse users and cause unnecessary side effects. 

Definition of Done

• MachineConfig and MachineConfigPool should not be present, they should be either removed or hidden when the cluster is spawned using HyperShift. 
• Cluster Settings show say the control plane is externally managed and be read-only.
• Cluster Settings -> Configuration resources should be read-only, maybe hide the tab
• Some resources should go in an allowlist. Most will be hidden
• Review getting started steps

See Design Doc: https://docs.google.com/document/d/1k76JtRRHBdCCEjHPqKcYvbNVsuaGmRhWDLESWIm0mbo/edit#

Setup / Testing

It's based on the SERVER_FLAG controlPlaneTopology being set to External is really the driving factor here; this can be done in one of two ways:

• Locally via a Bridge Variable, export BRIDGE_CONTROL_PLANE_TOPOLOGY_MODE="External"
• Locally / OnCluster via modifying the window.SERVER_FLAGS.controlPlaneTopology to External in the dev tools

To test work related to cluster upgrade process, use a 4.10.3 cluster set on the candidate-4.10 upgrade channel using 4.11 frontend code.

Epic Goal

• Ensure that OCP Admin console can enable dark mode
• Mechanism for switching between light/dark mode, based on user preferences or User Settings in OCP
• Identify changes needed for OCP console's dynamic plugins
• Status as we work through the stories: https://docs.google.com/document/d/18ib0A9ZtSYo1e2aOtM2LtZcsNFs1aRCHXx6NAPsIAso/edit#

Why is this important?

• So the UX satisfies the current trands, where dark mode is becoming a standard for modern services.  

Acceptance Criteria

• OCP admin console must be rendered in a preferred mode based on `prefers-color-scheme` media query
• OCP admin console must be rendered in a preferred mode selected in the User Setting page
• Create an followup epic/story for and listing and tracking changes needed in OCP console's dynamic plugins

Open questions::

1. Who should be responsible for updating DynamicPlugins to be able to render in dark mode?

An epic we can duplicate for each release to ensure we have a place to catch things we ought to be doing regularly but can tend to fall by the wayside.

This epic contains all the Dynamic Plugins related stories for OCP release-4.11 

Epic Goal

• Track all the stories under a single epic

Acceptance Criteria

Goal

• Add the ability for users to select supported but not recommended updates.
• Refine workflow when both "upgradeable=false" and "supported-but-not-recommended" updates occur

Background
RFE: for 4.10, Cincinnati and the cluster-version operator are adding conditional updates (a.k.a. targeted edge blocking): https://issues.redhat.com/browse/OTA-267

High-level plans in https://github.com/openshift/enhancements/blob/master/enhancements/update/targeted-update-edge-blocking.md#update-client-support-for-the-enhanced-schema

Example of what the oc adm upgrade UX will be in https://github.com/openshift/enhancements/blob/master/enhancements/update/targeted-update-edge-blocking.md#cluster-administrator.

The oc implementation landed via https://github.com/openshift/oc/pull/961.

Design

• Use case 01: "supported but not recommended" occurs to the latest version:
  • Add an info icon next to the version on update path with a pop-over to explain about why updating to this version is supported, but not recommended and a link to known risks
  • Identify the difference in "recommended" versions, "supported but not recommended" versions, and "blocked" versions (upgradeable=false) in the + more modal.
  • The latest version is pre-selected in the dropdown in the update modal with an inline alert to inform users about supported-but-not-recommended version with link to known risks. Users can choose to update to another recommended versions, update to a supported-but-not-recommended one, or wait.
  • The "recommended" and "supported but not recommended" updates are separated in the dropdown.
  • If a user selects a "recommended" update, the inline alert disappears.
• Use case 02: When both "upgradeable=false" and "supported but not recommended" occur:
  • Add an alert banner to explain why users shouldn’t update to the latest version and link to how to resolve on the cluster settings details page. Users have the options to resolve the issue, update to a patch version, or wait.
  • If users open the update modal without resolving the "upgradeable=false" issue, the next recommended version is pre-selected. An expandable link "View blocked versions (#)" is included under the dropdown to show "upgradeable=false" versions with resolve link.
  • If users resolve the "upgradeable=false" issue, the cluster settings page will change to use case 01

• • Question: Priority on changing the upgradeable=false alert banner in update modal and blocked versions in dropdown

Goal

Remove Jenkins from the OCP Payload.

Problem

• Jenkins images are "non-trival in size, impact experience around OCP payloads
• Security advisories cannot be handled once, but against all actively supported OCP releases, adding to response time for handling said advisories
• Some customers may now want to upgrade Jenkins as OCP upgrades (making this configurable is more ideal)

Why is this important

• This is an engineering motivated item to reduce costs so we have more cycles for strategic work
• Aside from the team itself, top level OCP architects want this to reduce the image size, improve general OCP upgrade experience
• Sends a mix message with respect to what is startegic CI/CI when Jenkins is baked into OCP, but Tekton/Pipelines is an add-on, day 2 install sort of thing

Dependencies (internal and external)

See epic linking - need alternative non payload image available to provide relatively seamless migration

Also, the EP for this is approved and merged at https://github.com/openshift/enhancements/blob/master/enhancements/builds/remove-jenkins-payload.md

Estimate (xs, s, m, l, xl, xxl):

Questions:

• in addition to needing the CPaaS Image available first, have we confirmed the "deprecate first, then remove" requirements?  Per grooming we've assigned Rob Gormley the task https://issues.redhat.com/browse/JKNS-274 for tracking this down.  I will be reaching out to Ben Parees (he is currently on vacation) to confirm from an OCP staff engineer / architect perspective if his approval of https://github.com/openshift/enhancements/pull/841 is sufficient signoff from that end.

       PARTIAL ANSWER ^^:  confirmed with Ben Parees in https://coreos.slack.com/archives/C014MHHKUSF/p1646683621293839 that EP merging is currently sufficient OCP "technical leadership" approval.

Epic Goal

When users configure CMO to interact with systems outside of an OpenShift cluster, we want to provide an easy way to add the cluster ID to the data send.

Why is this important?

Technically this can be achieved today, by adding an identifying label to the remote_write configuration for a given cluster. The operator adding the remote_write integration needs to take care that the label is unique over the managed fleet of clusters. This however adds management complexity. Any given cluster already has a pseudo-unique datum, that can be used for this purpose.

• Starting in 4.9 we support the Prometheus remote_write feature to send metric data to a storage integration outside of the cluster similar to our own Telemetry service.
• In Telemetry we already use the cluster ID to distinguish the various clusters.
• For users of remote_write this could add an easy way to add such distinguishing information.

Scenarios

1. An organisation with multiple OpenShift clusters want to store their metric data centralized in a dedicated system and use remote_write in all their clusters to send this data. When querying their centralized storage, metadata (here a label) is needed to separate the data of the various clusters.
2. Service providers who manage multiple clusters for multiple customers via a centralized storage system need distinguishing metadata too. See https://issues.redhat.com/browse/OSD-6573 for example

Acceptance Criteria

• CI - MUST be running successfully with tests automated
• Release Technical Enablement - Provide necessary release enablement details and documents.
• Document how to use this feature

• DOC - Downstream documentation merged: <link to meaningful PR>

Implementation proposal:

Expose a flag in the CMO configuration, that is false by default (keeps backward compatibility) and when set to true will add the _id label to a remote_write configuration. More specifically it will be added to the top of a remote_write relabel_config list via the replace action. This will add the label as expect, but additionally a user could alter this label in a later relabel config to suit any specific requirements (say rename the label or add additional information to the value).
The location of this flag is the remote_write Spec, so this can be set for individual remote_write configurations.

Epic Goal

• Offer the option to double the scrape intervals for CMO controlled ServiceMonitors in single node deployments
• Alternatively automatically double the same scrape intervals if CMO detects an SNO setup

The potential target ServiceMonitors are:

• kubelet
• kube-state-metrics
• node-exporter
• etcd
• openshift-state-metrics

Why is this important?

• Reduce CPU usage in SNO setups
• Specifically doubling the scrape interval is important because:

1. we are confident that this will have the least chance to interfere with existing rules. We typically have rate queries over the last 2 minutes (no shorter time window). With 30 second scrape intervals (the current default) this gives us 4 samples in any 2 minute window. rate needs at least 2 samples to work, we want another 2 for failure tolerance. Doubling the scrape interval will still give us 2 samples in most 2 minute windows. If a scrape fails, a few rule evaluations might fail intermittently.
2. We expect a measureable reduction of CPU resources (see previous work)

Scenarios

1. RAN deployments (Telco Edge) are SNO deployments. In these setups a full CMO deployment is often not needed and the default setup consumes too many resources. OpenShift as a whole has only very limited CPU cycles available and too many cycles are spend on Monitoring

• CI - MUST be running successfully with tests automated
• Release Technical Enablement - Provide necessary release enablement details and documents.

Previous Work (Optional):

1. https://issues.redhat.com/browse/MON-1569

Open questions:

1. Whether doubling some scrape intervals reduces CPU usage to fit into the assigned budget

Non goals

• Allow arbitrarily long scrape intervals. This will interfere with alert and recoring rules
• Implement a global override to scrape intervals.

Problem:

Currently we are only able to get limited telemetry from the Dev Sandbox, but not from any of our managed clusters or on prem clusters.

Goals:

1. Enable gathering segment telemetry whenever cluster telemetry is enabled on OSD clusters
2. Have our OSD clusters opt into telemetry by default
3. Work with PM & UX to identify additional metrics to capture in addition to what we have enabled currently on Sandbox.
4. Ability to get a single report from woopra across all of our Sandbox and OSD clusters.
5. Be able to generate a report including metrics of a single cluster or all clusters of a certain type ( sandbox, or OSD)

Why is it important?

In order to improve properly analyze usage and the user experience, we need to be able to gather as much data as possible.

Goal:
Enhance oc adm release new (and related verbs info, extract, mirror) with heterogeneous architecture support

Epic Goal

• Update image registry dependencies (Kubernetes and OpenShift) to the latest versions.

Why is this important?

• New versions usually bring improvements that are needed by the registry and help with getting updates for z-stream.

Scenarios

1. As an OpenShift engineer, I want my components to use the versions of dependencies, so that they get fixes for known issues and can be easily updated in z-stream.

Epic Goal

• Provide a dedicated dashboard for NVIDIA GPU usage visualization in the OpenShift Console.

Why is this important?

• Customers that use GPUs in their clusters usually have the GPU workloads as the main purpose of their cluster. As such, it makes much more sense to have the details about the usage they are doing of GPGPU resources AND CPU/RAM rather than just CPU/RAM

Scenarios

1. As an admin of a cluster dedicated to data science, I want to quickly find out how much of my very costly resources are currently in use and if things are getting queued due to lack of resources

Acceptance Criteria

• CI - MUST be running successfully with tests automated
• Release Technical Enablement - Provide necessary release enablement details and documents.

Epic Goal

• Run OpenShift builds that do not execute as the "root" user on the host node.

Why is this important?

• OpenShift builds require an elevated set of capabilities to build a container image
• Builds currently run as root to maintain adequate performance
• Container workloads should run as non-root from the host's perspective. Containers running as root are a known security risk.
• Builds currently run as root and require a privileged container. See BUILD-225 for removing the privileged container requirement.

Scenarios

1. Run BuildConfigs in a multi-tenant environment
2. Run BuildConfigs in a heightened security environment/deployment

Acceptance Criteria

• Developers can opt into running builds in a cri-o user namespace by providing an environment variable with a specific value.
• When the correct environment variable is provided, builds run in a cri-o user namespace, and the build pod does not require the "privileged: true" security context.
• User namespace builds can pass basic test scenarios for the Docker and Source strategy build.
• Steps to run unprivileged builds are documented.

Dependencies (internal and external)

1. Buildah supports running inside a non-privileged container
2. CRI-O allows workloads to opt into running containers in user namespaces.

Previous Work (Optional):

1. BUILD-225 - remove privileged requirement for builds.

Kuryr might take a while to create Pods because it has to create Neutron ports for the pods. If a pod gets deleted while this is being processed, a
warning Event will be generated causing the "[sig-network] pods should successfully create sandboxes by adding pod to network" to fail.

Description of problem:
Switching the spec.endpointPublishingStrategy.loadBalancer.scope of the default ingresscontroller results in a degraded ingress operator. The routes using that endpoint like the console URL become inaccessible.
Degraded operators after scope change:

We have noticed that each time this happens the underlying AWS loadbalancer gets recreated which is as expected however the router pods probably do not get notified about the new loadbalancer. The instances in the new loadbalancer become 'outOfService'.

Restarting one of the router pods fixes the issue and brings back a couple of instances under the loadbalancer back to 'InService' which leads to the operators becoming happy again.

Version-Release number of selected component (if applicable):

ingress in 4.11.z however we suspect this issue to also apply to older versions

How reproducible:

Consistently reproducible

Steps to Reproduce:

1. Create a test OCP 4.11 cluster in AWS
2. Switch the spec.endpointPublishingStrategy.loadBalancer.scope of the default ingresscontroller in openshift-ingress-operator to Internal from External (or vice versa)
3. New Loadbalancer is created in AWS for the default router service, however the instances behind are not in service

Actual results:

ingress, authentication and console operators go into a degraded state. Console URL of the cluster is inaccessible

Expected results:

The ingresscontroller scope transition from internal->External (or vice versa) is smooth without any downtime or operators going into degraded state. The console is accessible.

Description of problem:

When services are deleted, the services controller cache should also remove the service from its top level cache to avoid growing forever.

While this is not an issue in 4.13 once the lb_cache rework merges [1], the 4.12 and older branches have this problem because that rework is meant for 4.13 only.

Description of problem:

Data upload form in storage -> PVC -> Data upload form, does not support source Ref.

Version-Release number of selected component (if applicable):

How reproducible:

100%

Steps to Reproduce:

1. storage -> PVC -> Data upload
2. click "Attach this data to a Virtual Machine operating system"
3. 

Actual results:

If the template using sourceRef ( and the source reference name is not identical to the PVC name ), the vm will use the sourceRef and not the uploaded data source.

Expected results:

a - do not allow to upload to specific template/s, ( use a different UI to manage sourceRef and importCron )
b - allow to upload to specific template/s, and make sure it works with sourceRef and importCron

When we update a Secret referenced in the BareMetalHost, an immediate reconcile of the corresponding BMH is not triggered. In most states we requeue each CR after a timeout, so we should eventually see the changes.

This is a public clone of OCPBUGS-3821

The MCO can sometimes render a rendered-config in the middle of an upgrade with old MCs, e.g.:

1. the containerruntimeconfigcontroller creates a new containerruntimeconfig due to the update
2. the template controller finishes re-creating the base configs
3. the kubeletconfig errors long enough and doesn't finish until after 2

This will cause the render controller to create a new rendered MC that uses the OLD kubeletconfig-MC, which at best is a double reboot for 1 node, and at worst block the update and break maxUnavailable nodes per pool.

Description of problem:

Similar to OCPBUGS-11636 ccoctl needs to be updated to account for the s3 bucket changes described in https://aws.amazon.com/blogs/aws/heads-up-amazon-s3-security-changes-are-coming-in-april-of-2023/

these changes have rolled out to us-east-2 and China regions as of today and will roll out to additional regions in the near future

See OCPBUGS-11636 for additional information

Version-Release number of selected component (if applicable):

How reproducible:

Reproducible in affected regions.

Steps to Reproduce:

1. Use "ccoctl aws create-all" flow to create STS infrastructure in an affected region like us-east-2. Notice that document upload fails because the s3 bucket is created in a state that does not allow usage of ACLs with the s3 bucket.

Actual results:

./ccoctl aws create-all --name abutchertestue2 --region us-east-2 --credentials-requests-dir ./credrequests --output-dir _output
2023/04/11 13:01:06 Using existing RSA keypair found at _output/serviceaccount-signer.private

The vSphere CSI cloud.conf lists the single datacenter from platform workspace config but in a multi-zone setup (https://github.com/openshift/enhancements/pull/918 ) there may be more than the one datacenter.

This issue is resulting in PVs failing to attach because the virtual machines can't be find in any other datacenter. For example:

0s Warning FailedAttachVolume pod/image-registry-85b5d5db54-m78vp AttachVolume.Attach failed for volume "pvc-ab1a0611-cb3b-418d-bb3b-1e7bbe2a69ed" : rpc error: code = Internal desc = failed to find VirtualMachine for node:"rbost-zonal-ghxp2-worker-3-xm7gw". Error: virtual machine wasn't found

Description of problem:

The reconciler removes the overlappingrangeipreservations.whereabouts.cni.cncf.io resources whether the pod is alive or not. 

Version-Release number of selected component (if applicable):

How reproducible:

Always

Steps to Reproduce:

1. Create pods and check the overlappingrangeipreservations.whereabouts.cni.cncf.io resources:

$ oc get overlappingrangeipreservations.whereabouts.cni.cncf.io -A
NAMESPACE          NAME                      AGE
openshift-multus   2001-1b70-820d-4b04--13   4m53s
openshift-multus   2001-1b70-820d-4b05--13   4m49s

2.  Verify that when the ip-reconciler cronjob removes the overlappingrangeipreservations.whereabouts.cni.cncf.io resources when run:

$ oc get cronjob -n openshift-multus
NAME            SCHEDULE       SUSPEND   ACTIVE   LAST SCHEDULE   AGE
ip-reconciler   */15 * * * *   False     0        14m             4d13h

$ oc get overlappingrangeipreservations.whereabouts.cni.cncf.io -A
No resources found

$ oc get cronjob -n openshift-multus
NAME            SCHEDULE       SUSPEND   ACTIVE   LAST SCHEDULE   AGE
ip-reconciler   */15 * * * *   False     0        5s              4d13h

Actual results:

The overlappingrangeipreservations.whereabouts.cni.cncf.io resources are removed for each created pod by the ip-reconciler cronjob.
The "overlapping ranges" are not used. 

Expected results:

The overlappingrangeipreservations.whereabouts.cni.cncf.io should not be removed regardless of if a pod has used an IP in the overlapping ranges.

Description of problem:

On the Machinesets, we configured the Azure tags, that should be assigned to the newly created nodes. VMs and disks have that tags assigned, while NICs - don't have configured Azsure tags assigned to them.

Version-Release number of selected component (if applicable):

OCP 4.11

How reproducible:

It can be reproducible

Steps to Reproduce:

1. We need to acquire Azure tags
2. Create machine set configs with Azure tags configured
3. Create VMs through the machine set

Actual results:

NICs, created by the Machinesets don't have Azure tags, configured on the Machineset.

Expected results:

NiCs should automatically pick up these tags.

Additional info:

As in Azure NICs can be treated as separate resources. there is a possibility if we assign the tags for the NICs in the main machine config file. it may work.

Description of problem:

The setting of systemReserved: ephemeral-storage in KubeletConfig is not working as expected. 

Version-Release number of selected component (if applicable):

4.10.z, may exist on other OCP versions as well. 

How reproducible:

always

Steps to Reproduce:

1. Create a KubeletConfig on the node:

apiVersion: machineconfiguration.openshift.io/v1
kind: KubeletConfig
metadata:
  name: system-reserved-config
spec:
  machineConfigPoolSelector:
    matchLabels:
      pools.operator.machineconfiguration.openshift.io/master: ""
  kubeletConfig:
    systemReserved:
      cpu: 500m
      memory: 500Mi
      ephemeral-storage: 10Gi


2. Check node allocatable storage with command: oc describe node |grep -C 5 ephemeral-storage

Actual results:

The Allocatable:ephemeral-storage on the node is not capacity.ephemeral-storage - systemReserved.ephemeral-storage - eviction-thresholds (10% of the capacity.ephemeral-storage by default)  

Expected results:

The Allocatable:ephemeral-storage on the node should be capacity.ephemeral-storage - systemReserved.ephemeral-storage - eviction-thresholds (10% of the capacity.ephemeral-storage by default) 

Additional info:

The root cause might be: process argument '--system-reserved=cpu=500m,memory=500Mi' overwrote the setting in /etc/kubernetes/kubelet.conf, one example:

root        6824       1 27 Sep30 ?        1-09:00:24 kubelet --config=/etc/kubernetes/kubelet.conf --bootstrap-kubeconfig=/etc/kubernetes/kubeconfig --kubeconfig=/var/lib/kubelet/kubeconfig --container-runtime=remote --container-runtime-endpoint=/var/run/crio/crio.sock --runtime-cgroups=/system.slice/crio.service --node-labels=node-role.kubernetes.io/master,node.openshift.io/os_id=rhcos --node-ip=192.168.58.47 --minimum-container-ttl-duration=6m0s --cloud-provider= --volume-plugin-dir=/etc/kubernetes/kubelet-plugins/volume/exec --hostname-override= --register-with-taints=node-role.kubernetes.io/master=:NoSchedule --pod-infra-container-image=quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:4a7b6408460148cb73c59677dbc2c261076bc07226c43b0c9192cc70aef5ba62 --system-reserved=cpu=500m,memory=500Mi --v=2 --housekeeping-interval=30s

Description of problem:

We experienced two separate upgrade failures relating to the introduction of the SYSTEM_RESERVED_ES node sizing parameter, causing kubelet to stop running.

One cluster (clusterA) upgraded from 4.11.14 to 4.11.17. It experienced an issue whereby 
   /etc/node-sizing.env 
on its master nodes contained an empty SYSTEM_RESERVED_ES value:

---
cat /etc/node-sizing.env 
SYSTEM_RESERVED_MEMORY=5.36Gi
SYSTEM_RESERVED_CPU=0.11
SYSTEM_RESERVED_ES=
---

causing the kubelet to not start up. To restore service, this file was manually updated to set a value (1Gi), and kubelet was restarted.

We are uncertain what conditions led to this occuring on the clusterA master nodes as part of the upgrade.

A second cluster (clusterB) upgraded from 4.11.16 to 4.11.17. It experienced an issue whereby worker nodes were impacted by a similar problem, however this was because a custom node-sizing-enabled.env MachineConfig which did not set SYSTEM_RESERVED_ES

This caused existing worker nodes to go into a NotReady state after the ugprade, and additionally new nodes did not join the cluster as their kubelet would become impacted. 

For clusterB the conditions are more well-known of why the value is empty.

However, for both clusters, if SYSTEM_RESERVED_ES ends up as empty on a node it can cause the kubelet to not start. 

We have some asks as a result:
- Can MCO be made to recover from this situation if it occurs, perhaps  through application of a safe default if none exists, such that kubelet would start correctly?
- Can there possibly be alerting that could indicate and draw attention to the misconfiguration?

Version-Release number of selected component (if applicable):

4.11.17

How reproducible:

Have not been able to reproduce it on a fresh cluster upgrading from 4.11.16 to 4.11.17

Expected results:

If SYSTEM_RESERVED_ES is empty in /etc/node-sizing*env then a default should be applied and/or kubelet able to continue running.

While I am not aware of this issue being reported against 4.11, due to the fact that the fix is only present in 4.12 codebase, 4.11 versions will also be affected by this issue.

This bug is created to meet automation requirements for backporting the fixes from 4.12 version to 4.11 (and then to 4.11 in the bug quoted above).

Version-Release number of selected component (if applicable):

4.13.0-ec.3. The behavior was apparently introduced as part of OCPBUGS-6018, which has been backported, so the following update targets are expected to be vulnerable: 4.10.52+, 4.11.26+, 4.12.2+, and 4.13.0-ec.3.

How reproducible:

100%, when updating into a vulnerable release, if you happen to have leaked MachineConfig.

Steps to Reproduce:

1. 4.12.0-ec.1 dropped cleanUpDuplicatedMC. Run a later release, like 4.13.0-ec.2.
2. Create more than one KubeletConfig or ContainerRuntimeConfig targeting the worker pool (or any pool other than master). The number of clusters who have had redundant configuration objects like this is expected to be small.
3. (Optionally?) delete the extra KubeletConfig and ContainerRuntimeConfig.
4. Update to 4.13.0-ec.3.

Actual results:

Update sticks on the machine-config ClusterOperator, as described above.

Expected results:

Update completes without issues.

Description of problem:

While looking into OCPBUGS-5505 I discovered that some 4.10->4.11 upgrade job runs perform an Admin Ack check, while some do not. 4.11 has a ack-4.11-kube-1.25-api-removals-in-4.12 gate, so these upgrade jobs sometimes test that Upgradeable goes false after the ugprade, and sometimes they do not. This is only determined by the polling race condition: the check is executed once per 10 minutes, and we cancel the polling after upgrade is completed. This means that in some cases we are lucky and manage to run one check before the cancel, and sometimes we are not and only check while still on the base version.

Example job that checked admin acks post-upgrade:
https://prow.ci.openshift.org/view/gs/origin-ci-test/logs/openshift-cluster-version-operator-880-ci-4.11-upgrade-from-stable-4.10-e2e-azure-upgrade/1611444032104304640

Description of problem:

It appears it may be possible to have invalid CSV entries in the resolver cache, resulting in the inability to reinstall an Operator.

The situation:
--------------
A customer has removed the CSV, InstallPlan and Subscription for the GitOps Operator from the cluster but upon attempting to reinstall the Operator, the OLM was providing a conflict with existing CSV.

This CSV was not in the ETCD instance and was removed previously. Upon deleting the `operator-catalog` and `operator-lifecycle-manager` Pods, the collision was resolved and the Operator was able to installed again.
~~~
'Warning' reason: 'ResolutionFailed' constraints not satisfiable: subscription openshift-gitops-operator exists, subscription openshift-gitops-operator requires redhat-operators/openshift-marketplace/stable/openshift-gitops-operator.v1.5.8, redhat-operators/openshift-marketplace/stable/openshift-gitops-operator.v1.5.8 and @existing/openshift-operators//openshift-gitops-operator.v1.5.6-0.1664915551.p originate from package openshift-gitops-operator, clusterserviceversion openshift-gitops-operator.v1.5.6-0.1664915551.p exists and is not referenced by a subscription
~~~

Version-Release number of selected component (if applicable):

4.9.31

How reproducible:

Very intermittent, however once the issue has occurred it was impossible to avoid without deleting the Pods.

Steps to Reproduce:

1. Add Operator with manual approval InstallPlan
2. Remove Operator (Subscription, CSV, InstallPlan)
3. Attempt to reinstall Operator 

Actual results:

Very intermittent failure

Expected results:

Operators do not have conflicts with CSVs which have already been removed.

Additional info:

Briefly reviewing the OLM code, it appears an internal resolver cache is populated and used for checking constraints when an operator is installed. If there are stale entries in the cache, this would result in the described issue.
The cache appears to have been rearchitected (moved to a dedicated object) since OCP 4.9.31. Due to the nature of this issue, the request does not have clear reproduction steps to reproduce so if the issue is unable to reproduced, I would like instructions on how to dump the contents of the cache if the issue is to arise again.

1. Proposed title of this feature request
--> Alert generation when the etcd container memory consumption goes beyond 90%

2. What is the nature and description of the request?
--> When the etcd database starts growing rapidly due to some high number of objects like secrets, events, or configmap generation by application/workload, the memory and CPU consumption of APIserver and etcd container (control plane component) spikes up and eventually the control plane nodes goes to hung/unresponsive or crash due to out of memory errors as some of the critical processes/services running on master nodes get killed. Hence we request an alert/alarm when the ETCD container's memory consumption goes beyond 90% so that the cluster administrator can take some action before the cluster/nodes go unresponsive.

I see we already have a etcdExcessiveDatabaseGrowth Prometheus rule which helps when the surge in etcd writes leading to a 50% increase in database size over the past four hours on etcd instance however it does not consider the memory consumption:

$ oc get prometheusrules etcd-prometheus-rules -o yaml|grep -i etcdExcessiveDatabaseGrowth -A 9

• alert: etcdExcessiveDatabaseGrowth
  annotations:
  description: 'etcd cluster "{{ $labels.job }}": Observed surge in etcd writes
  leading to 50% increase in database size over the past four hours on etcd
  instance {{ $labels.instance }}, please check as it might be disruptive.'
  expr: |
  increase(((etcd_mvcc_db_total_size_in_bytes/etcd_server_quota_backend_bytes)*100)[240m:1m]) > 50
  for: 10m
  labels:
  severity: warning

3. Why does the customer need this? (List the business requirements here)
--> Once the etcd memory consumption goes beyond 90-95% of total ram as it's system critical container, the OCP cluster goes unresponsive causing revenue loss to business and impacting the productivity of users of the openshift cluster. 

4. List any affected packages or components.
--> etcd

This is a 4.11.z backport.  By not backporting this change originally to 4.11 we introduced a mandatory flag for `opm serve` command without at least a 2-OCP-version runway as optional.   This is impacting customers on 4.11 clusters as well as dependent peer projects like oc-mirror.

-----------------------------

Description of problem:

opm serve fails with message:

Error: compute digest: compute hash: write tar: stat .: os: DirFS with empty root

Version-Release number of selected component (if applicable):

4.12
