1. Proposed title of this feature request
Add runbook_url to alerts in the OCP UI
2. What is the nature and description of the request?
If an alert includes a runbook_url label, then it should appear in the UI for the alert as a link.
3. Why does the customer need this? (List the business requirements here)
Customer can easily reach the alert runbook and be able to address their issues.
4. List any affected packages or components.
As a user, I should be able to configure CSI driver to have a storage topology.
Epic Goal
- Make it possible to disable the console operator at install time, while still having a supported+upgradeable cluster.
Why is this important?
- It's possible to disable console itself using spec.managementState in the console operator config. There is no way to remove the console operator, though. For clusters where an admin wants to completely remove console, we should give the option to disable the console operator as well.
Scenarios
- I'm an administrator who wants to minimize my OpenShift cluster footprint and who does not want the console installed on my cluster
Acceptance Criteria
- It is possible at install time to opt-out of having the console operator installed. Once the cluster comes up, the console operator is not running.
Dependencies (internal and external)
- Composable cluster installation

Open questions::
- The console operator manages the downloads deployment as well. Do we disable the downloads deployment? Long term we want to move to CLI manager: https://github.com/openshift/enhancements/blob/6ae78842d4a87593c63274e02ac7a33cc7f296c3/enhancements/oc/cli-manager.md

In the console-operator repo we need to add `capability.openshift.io/console` annotation to all the manifests that the operator either contains creates on the fly.
Manifests are currently present in /bindata and /manifest directories.
Here is example of the insights-operator change.
Here is the overall enhancement doc.
Feature Overview
Provide CSI drivers to replace all the intree cloud provider drivers we currently have. These drivers will probably be released as tech preview versions first before being promoted to GA.
Goals
- Framework for rapid creation of CSI drivers for our cloud providers
- CSI driver for AWS EBS
- CSI driver for AWS EFS
- CSI driver for GCP
- CSI driver for Azure
- CSI driver for VMware vSphere
- CSI Driver for Azure Stack
- CSI Driver for Alicloud
- CSI Driver for IBM Cloud
Requirements
| Requirement | Notes | isMvp? |
|---|---|---|
| Framework for CSI driver | TBD | Yes |
| Drivers should be available to install both in disconnected and connected mode | Yes | |
| Drivers should upgrade from release to release without any impact | Yes | |
| Drivers should be installable via CVO (when in-tree plugin exists) |
Out of Scope
This work will only cover the drivers themselves, it will not include
- enhancements to the CSI API framework
- the migration to said drivers from the the intree drivers
- work for non-cloud provider storage drivers (FC-SAN, iSCSI) being converted to CSI drivers
Background, and strategic fit
In a future Kubernetes release (currently 1.21) intree cloud provider drivers will be deprecated and replaced with CSI equivalents, we need the drivers created so that we continue to support the ecosystems in an appropriate way.
Assumptions
- Storage SIG won't move out the changeover to a later Kubernetes release
Customer Considerations
Customers will need to be able to use the storage they want.
Documentation Considerations
- Target audience: cluster admins
- Updated content: update storage docs to show how to use these drivers (also better expose the capabilities)
This Epic is to track the GA of this feature
Goal
- Make available the Google Cloud File Service via a CSI driver, it is desirable that this implementation has dynamic provisioning
- Without GCP filestore support, we are limited to block / RWO only (GCP PD 4.8 GA)
- Align with what we support on other major public cloud providers.
Why is this important?
- There is a know storage gap with google cloud where only block is supported
- More customers deploying on GCE and asking for file / RWX storage.
Scenarios
- Install the CSI driver
- Remove the CSI Driver
- Dynamically provision a CSI Google File PV*
- Utilise a Google File PV
- Assess optional features such as resize & snapshot
Acceptance Criteria
- CI - MUST be running successfully with tests automated

As an OCP user, I want images for GCP Filestore CSI Driver and Operator, so that I can install them on my cluster and utilize GCP Filestore shares.
We need to continue to maintain specific areas within storage, this is to capture that effort and track it across releases.
Goals
- To allow OCP users and cluster admins to detect problems early and with as little interaction with Red Hat as possible.
- When Red Hat is involved, make sure we have all the information we need from the customer, i.e. in metrics / telemetry / must-gather.
- Reduce storage test flakiness so we can spot real bugs in our CI.
Requirements
| Requirement | Notes | isMvp? |
|---|---|---|
| Telemetry | No | |
| Certification | No | |
| API metrics | No | |
Out of Scope
n/a
Background, and strategic fit
With the expected scale of our customer base, we want to keep load of customer tickets / BZs low
Assumptions
Customer Considerations
Documentation Considerations
- Target audience: internal
- Updated content: none at this time.
Notes
In progress:
- CSI certification flakes a lot. We should fix it before we start testing migration.
- In progress (API server restarts...) https://bugzilla.redhat.com/show_bug.cgi?id=1865857
- Get local-storage-operator and AWS EBS CSI driver operator logs in must-gather (OLM-managed operators are not included there)
- In progress for LSO (must-gather script being included in image) https://bugzilla.redhat.com/show_bug.cgi?id=1756096
- CI flakes:
- Configurable timeouts for e2e tests
- Azure is slow and times out often
- Cinder times out formatting volumes
- AWS resize test times out
- Configurable timeouts for e2e tests
High prio:
- Env. check tool for VMware - users often mis-configure permissions there and blame OpenShift. If we had a tool they could run, it might report better errors.
- Should it be part of the installer?
- Spike exists
- Add / use cloud API call metrics
-
- Helps customers to understand why things are slow
- Helps build cop to understand a flake
- With a post-install step that filters data from Prometheus that’s still running in the CI job.
- Ideas:
- Cloud is throttling X% of API calls longer than Y seconds
- Attach / detach / provisioning / deletion / mount / unmount / resize takes longer than X seconds?
- Capture metrics of operations that are stuck and won’t finish.
- Sweep operation map from executioner???
- Report operation metric into the highest bucket after the bucket threshold (i.e. if 10minutes is the last bucket, report an operation into this bucket after 10 minutes and don’t wait for its completion)?
- Ask the monitoring team?
- Include in CSI drivers too.
- With alerts too
- Report events for cloud issues
- E.g. cloud API reports weird attach/provision error (e.g. due to outage)
- What volume plugins actually users use the most? https://issues.redhat.com/browse/STOR-324
Unsorted
- As the number of storage operators grows, it would be grafana board for storage operators
- CSI driver metrics (from CSI sidecars + the driver itself + its operator?)
- CSI migration?
- Get aggregated logs in cluster
- They're rotated too soon
- No logs from dead / restarted pods
- No tools to combine logs from multiple pods (e.g. 3 controller managers)
- What storage issues customers have? it was 22% of all issues.
- Insufficient docs?
- Probably garbage
- Document basic storage troubleshooting for our supports
- What logs are useful when, what log level to use
- This has been discussed during the GSS weekly team meeting; however, it would be beneficial to have this documented.
- Common vSphere errors, their debugging and fixing.
- Document sig-storage flake handling - not all failed [sig-storage] tests are ours
The End of General support for vSphere 6.7 will be on October 15, 2022. So, vSphere 6.7 will be deprecated for 4.11.
We want to encourage vSphere customers to upgrade to vSphere 7 in OCP 4.11 since VMware is EOLing (general support) for vSphere 6.7 in Oct 2022.
We want the cluster Upgradeable=false + have a strong alert pointing to our docs / requirements.

Epic Goal
- Update all images that we ship with OpenShift to the latest upstream releases and libraries.
- Exact content of what needs to be updated will be determined as new images are released upstream, which is not known at the beginning of OCP development work. We don't know what new features will be included and should be tested and documented. Especially new CSI drivers releases may bring new, currently unknown features. We expect that the amount of work will be roughly the same as in the previous releases. Of course, QE or docs can reject an update if it's too close to deadline and/or looks too big.
Traditionally we did these updates as bugfixes, because we did them after the feature freeze (FF). Trying no-feature-freeze in 4.12. We will try to do as much as we can before FF, but we're quite sure something will slip past FF as usual.
Why is this important?
- We want to ship the latest software that contains new features and bugfixes.
Acceptance Criteria
- CI - MUST be running successfully with tests automated
- Release Technical Enablement - Provide necessary release enablement details and documents.
Update the driver to the latest upstream release. Notify QE and docs with any new features and important bugfixes that need testing or documentation.

Epic Goal
- Enable the migration from a storage intree driver to a CSI based driver with minimal impact to the end user, applications and cluster
- These migrations would include, but are not limited to:
- CSI driver for AWS EBS
- CSI driver for GCP
- CSI driver for Azure (file and disk)
- CSI driver for VMware vSphere
Why is this important?
- OpenShift needs to maintain it's ability to enable PVCs and PVs of the main storage types
- CSI Migration is getting close to GA, we need to have the feature fully tested and enabled in OpenShift
- Upstream intree drivers are being deprecated to make way for the CSI drivers prior to intree driver removal
Scenarios
- User initiated move to from intree to CSI driver
- Upgrade initiated move from intree to CSI driver
- Upgrade from EUS to EUS
Acceptance Criteria
- CI - MUST be running successfully with tests automated
- Release Technical Enablement - Provide necessary release enablement details and documents.

On new installations, we should make the StorageClass created by the CSI operator the default one.
However, we shouldn't do that on an upgrade scenario. The main reason is that users might have set a different quota on the CSI driver Storage Class.
Exit criteria:
- New clusters get the CSI Storage Class as the default one.
- Existing clusters don't get their default Storage Classes changed.

Rebase openshift-controller-manager to k8s 1.24
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
- 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.
- 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.
- We cannot assume that we will have access to a computer to run an installer or installer helper software.
Customer Considerations
- ...
Documentation Considerations
Questions to be addressed:
- What educational or reference material (docs) is required to support this product feature? For users/admins? Other functions (security officers, etc)?
- Does this feature have doc impact?
- New Content, Updates to existing content, Release Note, or No Doc Impact
- If unsure and no Technical Writer is available, please contact Content Strategy.
- What concepts do customers need to understand to be successful in [action]?
- How do we expect customers will use the feature? For what purpose(s)?
- What reference material might a customer want/need to complete [action]?
- Is there source material that can be used as reference for the Technical Writer in writing the content? If yes, please link if available.
- What is the doc impact (New Content, Updates to existing content, or Release Note)?

Epic Goal
As a OpenShift infrastructure owner, I want to deploy OpenShift clusters with dual-stack IPv4/IPv6
As a OpenShift infrastructure owner, I want to deploy OpenShift clusters with single-stack IPv6
Why is this important?
IPv6 and dual-stack clusters are requested often by customers, especially from Telco customers. Working with dual-stack clusters is a requirement for many but also a transition into a single-stack IPv6 clusters, which for some of our users is the final destination.
Acceptance Criteria
- Agent-based installer can deploy IPv6 clusters
- Agent-based installer can deploy dual-stack clusters
- CI - MUST be running successfully with tests automated
- Release Technical Enablement - Provide necessary release enablement details and documents.

For dual-stack installations the agent-cluster-install.yaml must have both an IPv4 and IPv6 subnet in the networkking.MachineNetwork or assisted-service will throw an error. This field is in InstallConfig but it must be added to agent-cluster-install in its Generate().
For IPv4 and IPv6 installs, setting up the MachineNetwork is not needed but it also does not cause problems if its set, so it should be fine to set it all times.
Epic Goal
As an OpenShift infrastructure owner, I want to deploy a cluster zero with RHACM or MCE and have the required components installed when the installation is completed
Why is this important?
BILLI makes it easier to deploy a cluster zero. BILLI users know at installation time what the purpose of their cluster is when they plan the installation. Day-2 steps are necessary to install operators and users, especially when automating installations, want to finish the installation flow when their required components are installed.
Acceptance Criteria
- A user can provide MCE manifests and have it installed without additional manual steps after the installation is completed
- CI - MUST be running successfully with tests automated
- Release Technical Enablement - Provide necessary release enablement details and documents.

Set the ClusterDeployment CRD to deploy OpenShift in FIPS mode and make sure that after deployment the cluster is set in that mode
In order to install FIPS compliant clusters, we need to make sure that installconfig + agentoconfig based deployments take into account the FIPS config in installconfig.
This task is about passing the config to agentclusterinstall so it makes it into the iso. Once there, AGENT-374 will give it to assisted service

We have carried a patch for the autoscaler that would enable the duplication of events. This patch can now be dropped because the upstream added a flag for this behavior in https://github.com/kubernetes/autoscaler/pull/4921
Steps
- add the --record-duplicated-events flag to all autoscaler deployments from the CAO
Stakeholders
- openshift eng
Definition of Done
- autoscaler continues to work as expected and produces events for everything
- Docs
- this does not require documentation as it preserves existing behavior and provides no interface for user interaction
- Testing
- current tests should continue to pass

This epic tracks the changes needed to the ingress operator to support IBM DNS Services for private clusters.
Background and Goal
Currently in OpenShift we do not support distributing hotfix packages to cluster nodes. In time-sensitive situations, a RHEL hotfix package can be the quickest route to resolving an issue.
Acceptance Criteria
- Under guidance from Red Hat CEE, customers can deploy RHEL hotfix packages to MachineConfigPools.
- Customers can easily remove the hotfix when the underlying RHCOS image incorporates the fix.
Before we ship OCP CoreOS layering in https://issues.redhat.com/browse/MCO-165 we need to switch the format of what is currently `machine-os-content` to be the new base image.
The overall plan is:
- Publish the new base image as `rhel-coreos-8` in the release image
- Also publish the new extensions container (https://github.com/openshift/os/pull/763) as `rhel-coreos-8-extensions`
- Teach the MCO to use this without also involving layering/build controller
- Delete old `machine-os-content`
After https://github.com/openshift/os/pull/763 is in the release image, teach the MCO how to use it. This is basically:
- Schedule the extensions container as a kubernetes service (just serves a yum repo via http)
- Change the MCD to write a file into `/etc/yum.repos.d/machine-config-extensions.repo` that consumes it instead of what it does now in pulling RPMs from the mounted container filesystem
As a OCP CoreOS layering developer, having telemetry data about number of cluster using osImageURL will help understand how broadly this feature is getting used and improve accordingly.
Acceptance Criteria:
- Cluster using Custom osImageURL is available via telemetry
Why?
- Decouple control and data plane.
- Customers do not pay Red Hat more to run HyperShift control planes and supporting infrastructure than Standalone control planes and supporting infrastructure.
- Improve security
- Shift credentials out of cluster that support the operation of core platform vs workload
- Improve cost
- Allow a user to toggle what they don’t need.
- Ensure a smooth path to scale to 0 workers and upgrade with 0 workers.
Assumption
- A customer will be able to associate a cluster as “Infrastructure only”
- E.g. one option: management cluster has role=master, and role=infra nodes only, control planes are packed on role=infra nodes
- OR the entire cluster is labeled infrastructure , and node roles are ignored.
- Anything that runs on a master node by default in Standalone that is present in HyperShift MUST be hosted and not run on a customer worker node.

Epic Goal
- To improve debug-ability of ovn-k in hypershift
- To verify the stability of of ovn-k in hypershift
- To introduce a EgressIP reach-ability check that will work in hypershift
Why is this important?
- ovn-k is supposed to be GA in 4.12. We need to make sure it is stable, we know the limitations and we are able to debug it similar to the self hosted cluster.
Acceptance Criteria
- CI - MUST be running successfully with tests automated
Dependencies (internal and external)
- This will need consultation with the people working on HyperShift

As OpenShift developer I want cluster-csi-snapshot-controller-operator to use existing controllers in library-go, so I don’t need to maintain yet another code that does the same thing as library-go.
- Check and remove manifests/03_configmap.yaml, it does not seem to be useful.
- Check and remove manifests/03_service.yaml, it does not seem to be useful (at least now).
- Use DeploymentController from library-go to sync Deployments.
- Get rid of common/ package? It does not seem to be useful.
- Use StaticResourceController for static content, including the snapshot CRDs.
Note: if this refactoring introduces any new conditions, we must make sure that 4.11 snapshot controller clears them to support downgrade! This will need 4.11 BZ + z-stream update!
Similarly, if some conditions become obsolete / not managed by any controller, they must be cleared by 4.12 operator.
Exit criteria:
- The operator code is smaller.
- No regressions in standalone OCP.

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
Market Problem
This Section: High-Level description of the Market Problem ie: Executive Summary
- As a customer of OpenShift layered products, I need to be able to fluidly, reliably and consistently install and use OpenShift layered product Kubernetes Operators into my ROSA STS clusters, while keeping a STS workflow throughout.
- As a customer of OpenShift on the big cloud providers, overall I expect OpenShift as a platform to function equally well with tokenized cloud auth as it does with "mint-mode" IAM credentials. I expect the same from the Kubernetes Operators under the Red Hat brand (that need to reach cloud APIs) in that tokenized workflows are equally integrated and workable as with "mint-mode" IAM credentials.
- As the managed services, including Hypershift teams, offering a downstream opinionated, supported and managed lifecycle of OpenShift (in the forms of ROSA, ARO, OSD on GCP, Hypershift, etc), the OpenShift platform should have as close as possible, native integration with core platform operators when clusters use tokenized cloud auth, driving the use of layered products.
- .
- As the Hypershift team, where the only credential mode for clusters/customers is STS (on AWS) , the Red Hat branded Operators that must reach the AWS API, should be enabled to work with STS credentials in a consistent, and automated fashion that allows customer to use those operators as easily as possible, driving the use of layered products.
Why it Matters
- Adding consistent, automated layered product integrations to OpenShift would provide great added value to OpenShift as a platform, and its downstream offerings in Managed Cloud Services and related offerings.
- Enabling Kuberenetes Operators (at first, Red Hat ones) on OpenShift for the "big3" cloud providers is a key differentiation and security requirement that our customers have been and continue to demand.
- HyperShift is an STS-only architecture, which means that if our layered offerings via Operators cannot easily work with STS, then it would be blocking us from our broad product adoption goals.
Illustrative User Stories or Scenarios
- Main success scenario - high-level user story
- customer creates a ROSA STS or Hypershift cluster (AWS)
- customer wants basic (table-stakes) features such as AWS EFS or RHODS or Logging
- customer sees necessary tasks for preparing for the operator in OperatorHub from their cluster
- customer prepares AWS IAM/STS roles/policies in anticipation of the Operator they want, using what they get from OperatorHub
- customer's provides a very minimal set of parameters (AWS ARN of role(s) with policy) to the Operator's OperatorHub page
- The cluster can automatically setup the Operator, using the provided tokenized credentials and the Operator functions as expected
- Cluster and Operator upgrades are taken into account and automated
- The above steps 1-7 should apply similarly for Google Cloud and Microsoft Azure Cloud, with their respective token-based workload identity systems.
- Alternate flow/scenarios - high-level user stories
- The same as above, but the ROSA CLI would assist with AWS role/policy management
- The same as above, but the oc CLI would assist with cloud role/policy management (per respective cloud provider for the cluster)
- ...
Expected Outcomes
This Section: Articulates and defines the value proposition from a users point of view
- See SDE-1868 as an example of what is needed, including design proposed, for current-day ROSA STS and by extension Hypershift.
- Further research is required to accomodate the AWS STS equivalent systems of GCP and Azure
- Order of priority at this time is
- 1. AWS STS for ROSA and ROSA via HyperShift
- 2. Microsoft Azure for ARO
- 3. Google Cloud for OpenShift Dedicated on GCP
Effect
This Section: Effect is the expected outcome within the market. There are two dimensions of outcomes; growth or retention. This represents part of the “why” statement for a feature.
- Growth is the acquisition of net new usage of the platform. This can be new workloads not previously able to be supported, new markets not previously considered, or new end users not previously served.
- Retention is maintaining and expanding existing use of the platform. This can be more effective use of tools, competitive pressures, and ease of use improvements.
- Both of growth and retention are the effect of this effort.
- Customers have strict requirements around using only token-based cloud credential systems for workloads in their cloud accounts, which include OpenShift clusters in all forms.
- We gain new customers from both those that have waited for token-based auth/auth from OpenShift and from those that are new to OpenShift, with strict requirements around cloud account access
- We retain customers that are going thru both cloud-native and hybrid-cloud journeys that all inevitably see security requirements driving them towards token-based auth/auth.
- Customers have strict requirements around using only token-based cloud credential systems for workloads in their cloud accounts, which include OpenShift clusters in all forms.
References
As an engineer I want the capability to implement CI test cases that run at different intervals, be it daily, weekly so as to ensure downstream operators that are dependent on certain capabilities are not negatively impacted if changes in systems CCO interacts with change behavior.
Acceptance Criteria:
Create a stubbed out e2e test path in CCO and matching e2e calling code in release such that there exists a path to tests that verify working in an AWS STS workflow.
OC mirror is GA product as of Openshift 4.11 .
The goal of this feature is to solve any future customer request for new features or capabilities in OC mirror
Epic Goal
- Mirror to mirror operations and custom mirroring flows required by IBM CloudPak catalog management
Why is this important?
- IBM needs additional customization around the actual mirroring of images to enable CloudPaks to fully adopt OLM-style operator packaging and catalog management
- IBM CloudPaks introduce additional compute architectures, increasing the download volume by 2/3rds to day, we need the ability to effectively filter non-required image versions of OLM operator catalogs during filtering for other customers that only require a single or a subset of the available image architectures
- IBM CloudPaks regularly run on older OCP versions like 4.8 which require additional work to be able to read the mirrored catalog produced by oc mirror
Scenarios
- Customers can use the oc utility and delegate the actual image mirror step to another tool
- Customers can mirror between disconnected registries using the oc utility
- The oc utility supports filtering manifest lists in the context of multi-arch images according to the sparse manifest list proposal in the distribution spec
Acceptance Criteria
- Customers can use the oc utility to mirror between two different air-gapped environments
- Customers can specify the desired computer architectures and oc mirror will create sparse manifest lists in the target registry as a result
Dependencies (internal and external)
- Sparse Manifest List Support in Red Hat Quay (PROJQUAY-3114)

Pre-Work Objectives
Since some of our requirements from the ACM team will not be available for the 4.12 timeframe, the team should work on anything we can get done in the scope of the console repo so that when the required items are available in 4.13, we can be more nimble in delivering GA content for the Unified Console Epic.
Overall GA Key Objective
Providing our customers with a single simplified User Experience(Hybrid Cloud Console)that is extensible, can run locally or in the cloud, and is capable of managing the fleet to deep diving into a single cluster.
Why customers want this?
- Single interface to accomplish their tasks
- Consistent UX and patterns
- Easily accessible: One URL, one set of credentials
Why we want this?
- Shared code - improve the velocity of both teams and most importantly ensure consistency of the experience at the code level
- Pre-built PF4 components
- Accessibility & i18n
- Remove barriers for enabling ACM
Phase 2 Goal: Productization of the united Console
- Enable user to quickly change context from fleet view to single cluster view
- Add Cluster selector with “All Cluster” Option. “All Cluster” = ACM
- Shared SSO across the fleet
- Hub OCP Console can connect to remote clusters API
- When ACM Installed the user starts from the fleet overview aka “All Clusters”
- Share UX between views
- ACM Search —> resource list across fleet -> resource details that are consistent with single cluster details view
- Add Cluster List to OCP —> Create Cluster
As a developer I would like to disable clusters like *KS that we can't support for multi-cluster (for instance because we can't authenticate). The ManagedCluster resource has a vendor label that we can use to know if the cluster is supported.
cc Ali Mobrem Sho Weimer Jakub Hadvig
UPDATE: 9/20/22 : we want an allow-list with OpenShift, ROSA, ARO, ROKS, and OpenShiftDedicated
Acceptance criteria:
- Investigate if console-operator should pass info about which cluster are supported and unsupported to the frontend
- Unsupported clusters should not appear in the cluster dropdown
- Unsupported clusters based off
- defined vendor label
- non 4.x ocp clusters

Overview
HyperShift came to life to serve multiple goals, some are main near-term, some are secondary that serve well long-term.
Main Goals for hosted control planes (HyperShift)
- Optimize OpenShift for Cost/footprint/ which improves our competitive stance against the *KSes
- Establish separation of concerns which makes it more resilient for SRE to manage their workload clusters (be it security, configuration management, etc).
- Simplify and enhance multi-cluster management experience especially since multi-cluster is becoming an industry need nowadays.
Secondary Goals
HyperShift opens up doors to penetrate the market. HyperShift enables true hybrid (CP and Workers decoupled, mixed IaaS, mixed Arch,...). An architecture that opens up more options to target new opportunities in the cloud space. For more details on this one check: Hosted Control Planes (aka HyperShift) Strategy [Live Document]
Hosted Control Planes (HyperShift) Map
To bring hosted control planes to our customers, we need the means to ship it. Today MCE is how HyperShift shipped, and installed so that customers can use it. There are two main customers for hosted-control-planes:
- Self-managed: In that case, Red Hat would provide hosted control planes as a service that is managed and SREed by the customer for their tenants (hence “self”-managed). In this management model, our external customers are the direct consumers of the multi-cluster control plane as a servie. Once MCE is installed, they can start to self-service dedicated control planes.
- Managed: This is OpenShift as a managed service, today we only “manage” the CP, and share the responsibility for other system components, more info here. To reduce management costs incurred by service delivery organizations which translates to operating profit (by reducing variable costs per control-plane), as well as to improve user experience, lower platform overhead (allow customers to focus mostly on writing applications and not concern themselves with infrastructure artifacts), and improve the cluster provisioning experience. HyperShift is shipped via MCE, and delivered to Red Hat managed SREs (same consumption route). However, for managed services, additional tooling needs to be refactored to support the new provisioning path. Furthermore, unlike self-managed where customers are free to bring their own observability stack, Red Hat managed SREs need to observe the managed fleet to ensure compliance with SLOs/SLIs/…
If you have noticed, MCE is the delivery mechanism for both management models. The difference between managed and self-managed is the consumer persona. For self-managed, it's the customer SRE for managed its the RH SRE.
High-level Requirements
For us to ship HyperShift in the product (as hosted control planes) in either management model, there is a necessary readiness checklist that we need to satisfy. Below are the high-level requirements needed before GA:
- Hosted control planes fits well with our multi-cluster story (with MCE)
- Hosted control planes APIs are stable for consumption
- Customers are not paying for control planes/infra components.
- Hosted control planes has an HA and a DR story
- Hosted control planes is in parity with top-level add-on operators
- Hosted control planes reports metrics on usage/adoption
- Hosted control planes is observable
- HyperShift as a backend to managed services is fully unblocked.
Please also have a look at our What are we missing in Core HyperShift for GA Readiness? doc.
Hosted control planes fits well with our multi-cluster story
Multi-cluster is becoming an industry need today not because this is where trend is going but because it’s the only viable path today to solve for many of our customer’s use-cases. Below is some reasoning why multi-cluster is a NEED:
As a result, multi-cluster management is a defining category in the market where Red Hat plays a key role. Today Red Hat solves for multi-cluster via RHACM and MCE. The goal is to simplify fleet management complexity by providing a single pane of glass to observe, secure, police, govern, configure a fleet. I.e., the operand is no longer one cluster but a set, a fleet of clusters.
HyperShift logically centralized architecture, as well as native separation of concerns and superior cluster lifecyle management experience, makes it a great fit as the foundation of our multi-cluster management story.
Thus the following stories are important for HyperShift:
- When lifecycling OpenShift clusters (for any OpenShift form factor) on any of the supported providers from MCE/ACM/OCM/CLI as a Cluster Service Consumer (RH managed SRE, or self-manage SRE/admin):
- I want to be able to use a consistent UI so I can manage and operate (observe, govern,...) a fleet of clusters.
- I want to specify HA constraints (e.g., deploy my clusters in different regions) while ensuring acceptable QoS (e.g., latency boundaries) to ensure/reduce any potential downtime for my workloads.
- When operating OpenShift clusters (for any OpenShift form factor) on any of the supported provider from MCE/ACM/OCM/CLI as a Cluster Service Consumer (RH managed SRE, or self-manage SRE/admin):
- I want to be able to backup any critical data so I am able to restore them in case of hosting service cluster (management cluster) failure.

Hosted control planes APIs are stable for consumption.
HyperShift is the core engine that will be used to provide hosted control-planes for consumption in managed and self-managed.
Main user story: When life cycling clusters as a cluster service consumer via HyperShift core APIs, I want to use a stable/backward compatible API that is less susceptible to future changes so I can provide availability guarantees.
Ref: What are we missing in Core HyperShift for GA Readiness?
Customers are not paying for control planes/infra components.
Customers do not pay Red Hat more to run HyperShift control planes and supporting infrastructure than Standalone control planes and supporting infrastructure.
Assumptions:
- A customer will be able to associate a cluster as “Infrastructure only”
- E.g. one option: management cluster has role=master, and role=infra nodes only, control planes are packed on role=infra nodes
- OR the entire cluster is labeled infrastructure , and node roles are ignored.
- Anything that runs on a master node by default in Standalone that is present in HyperShift MUST be hosted and not run on a customer worker node.
HyperShift - proposed cuts from data plane
HyperShift has an HA and a DR story
When operating OpenShift clusters (for any OpenShift form factor) from MCE/ACM/OCM/CLI as a Cluster Service Consumer (RH managed SRE, or self-manage SRE/admin) I want to be able to migrate CPs from one hosting service cluster to another:
- as means for disaster recovery in the case of total failure
- so that scaling pressures on a management cluster can be mitigated or a management cluster can be decommissioned.

Hosted control planes reports metrics on usage/adoption
To understand usage patterns and inform our decision making for the product. We need to be able to measure adoption and assess usage.
See Hosted Control Planes (aka HyperShift) Strategy [Live Document]
Hosted control plane is observable
Whether it's managed or self-managed, it’s pertinent to report health metrics to be able to create meaningful Service Level Objectives (SLOs), alert of failure to meet our availability guarantees. This is especially important for our managed services path.
HyperShift is in parity with top-level add-on operators

Unblock HyperShift as a backend to managed services
HyperShift for managed services is a strategic company goal as it improves usability, feature, and cost competitiveness against other managed solutions, and because managed services/consumption-based cloud services is where we see the market growing (customers are looking to delegate platform overhead).
We should make sure our SD milestones are unblocked by the core team.
Note
This feature reflects HyperShift core readiness to be consumed. When all related EPICs and stories in this EPIC are complete HyperShift can be considered ready to be consumed in GA form. This does not describe a date but rather the readiness of core HyperShift to be consumed in GA form NOT the GA itself.
- GA date for self-managed will be factoring in other inputs such as adoption, customer interest/commitment, and other factors.
- GA dates for ROSA-HyperShift are on track, tracked in milestones M1-7 (have a look at https://issues.redhat.com/browse/OCPPLAN-5771)
Epic Goal*
The goal is to split client certificate trust chains from the global Hypershift root CA.
Why is this important? (mandatory)
This is important to:
- assure a workload can be run on any kind of OCP flavor
- reduce the blast radius in case of a sensitive material leak
- separate trust to allow more granular control over client certificate authentication
Scenarios (mandatory)
Provide details for user scenarios including actions to be performed, platform specifications, and user personas.
- I would like to be able to run my workloads on any OpenShift-like platform.
My workloads allow components to authenticate using client certificates based
on a trust bundle that I am able to retrieve from the cluster.
- I don't want my users to have access to any CA bundle that would allow them
to trust a random certificate from the cluster for client certificate authentication.
Dependencies (internal and external) (mandatory)
Hypershift team needs to provide us with code reviews and merge the changes we are to deliver
Contributing Teams(and contacts) (mandatory)
- Development - OpenShift Auth, Hypershift
- Documentation -OpenShift Auth Docs team
- QE - OpenShift Auth QE
- PX - I have no idea what PX is
- Others - others
Acceptance Criteria (optional)
The serviceaccount CA bundle automatically injected to all pods cannot be used to authenticate any client certificate generated by the control-plane.
Drawbacks or Risk (optional)
Risk: there is a throbbing time pressure as this should be delivered before first stable Hypershift release
Done - Checklist (mandatory)

AUTH-311 introduced an enhancement. Implement the signer separation described there.
Cloned from OCPSTRAT-377 to represent the backport to 4.12
Backport questions:
1) What's the impact/cost to any other critical items on the next release?
Installer and edge are mostly focused on activation/retention and working the list top-to-bottom without release blockers. This is an activation item highly coveted by SD and applicable in existing versions.
2) Is it a breaking change to the existing fleet?
No.

API PR: https://github.com/openshift/api/pull/1460
Ingress Operator PR: https://github.com/openshift/cluster-ingress-operator/pull/928
Background
Feature Goal: Support OpenShift installation in AWS Shared VPC scenario where AWS infrastructure resources (at least the Private Hosted Zone) belong to an account separate from the cluster installation target account.
The ingress operator is responsible for creating DNS records in AWS Route53 for cluster ingress. Prior to the implementation of this epic, the ingress operator doesn't have the capability to add DNS records into an existing Route 53 hosted zone in the shared VPC.
Epic Goal
- Add support to the ingress operator for creating DNS records in preexisting Route53 private hosted zones for Shared VPC clusters
Non-Goals
- Ingress operator support for day-2 operations (i.e. changes to the AWS IAM Role value after installation)
- E2E testing (will be handled by the Installer Team)
Design
As described in the WIP PR https://github.com/openshift/cluster-ingress-operator/pull/928, the ingress operator will consume a new API field that contains the IAM Role ARN for configuring DNS records in the private hosted zone. If this field is present, then the ingress operator will use this account to create all private hosted zone records. The API fields will be described in the Enhancement PR.
The ingress operator code will accomplish this by defining a new provider implementation that wraps two other DNS providers, using one of them to publish records to the public zone and the other to publish records to the private zone.
External DNS Operator Impact
See NE-1299
AWS Load Balancer Operator (ALBO) Impact
See NE-1299
Why is this important?
- Without this ingress operator support, OpenShift users are unable to create DNS records in a preexisting Route53 private hosted zone which means OpenShift users can't share the Route53 component with a Shared VPC
- Shared VPCs are considers AWS best practice
Scenarios
- ...
Acceptance Criteria
- Unit tests must be written and automatically run in CI (E2E tests will be handled by the Installer Team)
- Release Technical Enablement - Provide necessary release enablement details and documents.
- Ingress Operator creates DNS Records in preexisting Route53 private hosted zones for shared VPC Clusters
- Network Edge Team has reviewed all of the related enhancements and code changes for Route53 in Shared VPC Clusters
Dependencies (internal and external)
- Installer Team is adding the new API fields required for enabling sharing Route53 with in Shared VPCs in https://issues.redhat.com/browse/CORS-2613
- Testing this epic requires having access to two AWS account
