Merge Risk: 🟠 High · up to The re-encryption coverage is not merge-ready: the e2ev2 package cannot compile, and several tests may report success without observing the intended key rotation.

Full details: Test Structure And QualityExplanation The new test file contains many assertions without meaningful failure messages. Examples include Resolution Add a diagnostic message to every assertion in the new file that currently has none. Include the operation and resource identity, such as Full details: Ipv6 And Disconnected Network Test CompatibilityExplanation The new AWS KMS and Azure KMS Ginkgo tests require access to cloud KMS services outside the cluster.

Since these tests only run when the CI jobs are appropriately configured with the new environment variables, this change has to be coordinated with a related PR to openshift/release which updates the jobs to set up the tests to execute, in addition to ensuring they're included in the test matrix for the relevant platforms. You'll need to open a corresponding PR to openshift/release which sets up the appropriate environment for Azure/AWS in the v2 jobs, and run rehearsals on the o/r PR which use a development image containing your changes (pushed to your own Quay repository or something) to prove that this PR will work in CI. Then we can merge this, and then immediately merge the o/r PR and thus enable CI coverage and observe the outcome (and either keep or revert). It's an annoying workflow in these cases but I'm not yet aware of a better way. Open to ideas. |

CNTRLPLANE-3525: Adds 5 v2 e2e tests validating the re-encryption lifecycle when encryption keys are rotated on a HostedCluster.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
priorHistoryLen is captured from a stale HostedCluster snapshot in four tests. Each site reads the HostedCluster before the initial waitForReEncryptionComplete, so a history entry appended during that wait makes the baseline one entry short. waitForReEncryptionStarted then succeeds on its first poll and the rotation start is never verified.

Summary
CNTRLPLANE-3525: Adds v2 e2e tests for the etcd re-encryption workflow introduced by #8219.
Also validates acceptance criteria for OCPSTRAT-2540 (etcd encryption key rotation status conditions).
Each rotation test verifies:

AWS KMS (AWS cluster):
Azure KMS (ARO-HCP cluster):
How to run
AWS KMS prerequisite
The alternate KMS key ARN (
E2E_AWS_KMS_KEY_ARN_ALTERNATE) must be added to the IAM role used by the KMS provider (e.g., thekms-providerinline policy). Without this, KAS cannot access the alternate key and the test will fail. Example:Azure KMS prerequisite
The alternate key version (
E2E_AZURE_KMS_KEY_VERSION_ALTERNATE) is a new version of the same key in the Azure Key Vault. Create one with:The new version ID is in the output's
