Epic CORS-1512: AWS: Support for C2S Region

Goal:

As an administrator, I would like to deploy OpenShift 4 clusters to AWS C2S region

Problem:

Customers were able to deploy to AWS C2S region in OCP 3.11, but our global configuration in OCP 4.1 doesn't support this.
  

Why is this important:

  • Many of our public sector customers would like to move off 3.11 and on to 4.1, but missing support for AWS C2S region will prevent them from being able to migrate their environments..

Lifecycle Information:

  • Core

Previous Work:**

Here are the relevant PRs from OCP 3.11.  You can see that these endpoints are not part of the standard SDK (they use an entirely separate SDK).  To support these regions the endpoints had to be configured explicitly.

Seth Jennings has put together a highly customized POC.

Dependencies:

  • Custom API endpoint support w/ CA
    • Cloud / Machine API
    • Image Registry
    • Ingress
    • Kube Controller Manager
    • Cloud Credential Operator
    • others?
  • Require access to local/private/hidden AWS environment

 

Prioritized epics + deliverables (in scope / not in scope):

  • Allow AWS C2S region to be specified for OpenShift cluster deployment
  • Enable customers to use their own managed internal/cluster DNS solutions due to provider and operational restrictions
  • Document deploying OpenShift to AWS C2S region
  • Enable CI for the AWS C2S region

Story BUILD-145: Fix usability with mirroring sample images in disconnected environments

User Story

As an cluster administrator of a disconnected OCP cluster,
I want a list of possible sample images to mirror
So that I can configure my image mirror prior to installing OCP in a disconnected environment.

Acceptance Criteria

  • Publish the list of the sample images to mirror as a ConfigMap in the samples operator namespace.
  • Provide instructions on how to obtain the current image SHAs from the list above (via podman or skopeo).
  • Reference the ConfigMap name in our "import failing" alert.
  • [optional] Reference the ConfigMap name in our "Removed" condition message.

Notes

it is too onerous to find a connected cluster in order to obtain the list of possible samples images to mirror using the current documented procedures.
I need a list make available to me in my disconnected cluster that I can reference after initial install.

Story BUILD-125: Improve recording of imagestream import results

User Story

Sample operator use of the reason field in its config object to track imagestream import completion has resulted in that singleton being a bottleneck and source of update conflicts (we are talking 60 or 70 imagestreams potentially updating that once field concurrently).

Acceptance Criteria

  • Reduction in reconciliation errors when imagestream imports complete (success or failure).
  • ConfigMaps containing failing imagstream imports are added to must-gather
  • After all imagestreams successfully import, there are no error-recording ConfigMaps in the samples-operator namespace.

Notes

See this hackday PR

for an alternative approach which uses a configmap per imagestream

Epic IR-115: OCI Support

Goal: Support OCI images.

Problem: Buildah and podman use OCI format by default and OpenShift Image Registry and ImageStream API doesn't understand it.

Why is this important: OCI images are supposed to replace Docker schema 2 images, OpenShift should be ready when OCI images become widely adopted.

Story IR-112: Add support of OCI images to image pruner

User Story

As a user of OpenShift
I want the image pruner to be aware of OCI images
So that it doesn't delete their layers/configs

Acceptance Criteria

    • When
      • an OCI image is pushed/mirrored to the registry
      • an schema 2 image is pushes/mirrored to the registry and share its layers/config with the OCI image
      • the schema 2 image is eligible to be pruned
      • the shared layers/config are not shared with other images
    • the pruner
      • will delete the schema 2 image
      • will NOT delete the OCI image and its layers/config

Epic IR-138: Continuous Improvement of Maintainability 4.7

Epic Goal

  • Improve CI testing of the image registry components.

Why is this important?

  • The image registry, image API and the image pruner had a lot of tests removed during transition 4.0. This may make the platform less stable and/or slow down the team.

Scenarios

  1. ...

Acceptance Criteria

  • CI - tests should be more stable and have broader coverage

Story IR-152: Monitor availability of registry during upgrade tests

An the registry developer
I want e2e-upgrade jobs to monitor availability of the registry during upgrades
So that I can be sure that clients can use the registry without disruptions.

Acceptance Criteria

  • A new test in openshift/origin repo.

Notes

https://github.com/openshift/origin/blob/e6b3d1ece61d7c3ab5a23151c9875e1f9ad36838/test/extended/util/disruption/controlplane/controlplane.go#L69

https://bugzilla.redhat.com/show_bug.cgi?id=1884380

Story IR-137: Make ISI tests non-disruptive

https://github.com/openshift/origin/pull/25475/files marked our tests for ISI as Disruptive.

Tests should wait until operators become stable, otherwise other tests will be run on an unstable cluster and it'll cause flakes.

Acceptance Criteria

  • The tests wait until operators stable after image.config changes.
  • The tests is no longer [Disruptive].
  • If tests are slow (it depends on other operator, but MCO tends to be slow), they should be [Slow].
Task IR-172: Convert image-registry integration tests into e2e tests

The integration tests for the image registry expect that OpenShift and tests are run on the same machine (i.e. OpenShift can connect to sockets that the tests listen). This is not the case with e2e tests.

Acceptance Criteria

  • every integration test is converted into an e2e test or a techdebt story
  • image-registry tests are green
Epic IR-85: Rebase Registry v2.7.1

Goal: Rebase registry to Docker Distribution 

Problem: The registry is currently based on an outdated version of the upstream docker/distribution project. The base does not even have a version associated with it - DevEx last rebased on an untagged commit.

Why is this important: Update the registry with improvements and bug fixes from the upstream community.

Task ETCD-178: refactor discover-etcd-initial-cluster and add tests

discover-etcd-initial-cluster was written very early on in the cluster-etcd-operator life cycle. We have observed at least one bug in this code and in order to validate logical correctness it needs to be rewritten with unit tests.
