Changes:

• Add ClusterProfileAWSEUSCQE constant ("aws-eusc-qe")
• Add profile to ClusterProfiles() list
• Add profile to ClusterType() aws case
• Add LeaseType() mapping to "aws-eusc-qe"

Region Details:

• Region: eusc-de-east-1 (Brandenburg, Germany)
• Partition: aws-eusc
• Availability zones: eusc-de-east-1a, eusc-de-east-1b

Dependencies:

• Release repo PR for boskos/secret configuration
• Installer support: CORS-4336: Support for AWS European Sovereign Cloud installer#10303

Pipeline controller notification
This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

This repository is configured in: automatic mode

Walkthrough

Adds a new cluster profile constant ClusterProfileAWSEUSC ("aws-eusc") and registers it in the public profile list, maps it to the AWS cluster type in ClusterType(), and maps it to the "aws-eusc" lease type in LeaseType().

Changes

Cohort / File(s)	Summary
Cluster profile & mappings pkg/api/types.go	Added ClusterProfileAWSEUSC ("aws-eusc") constant; included it in ClusterProfiles() slice; added cases mapping it to AWS in ClusterType() and returning "aws-eusc" in LeaseType(). (No changes to LeaseTypeFromClusterType in this diff.)

Build Error Analysis

This integration test failure is not related to PR #4973. The PR only adds a new cluster profile constant in pkg/api/types.go and doesn't touch any
testgrid-related code.

Root Cause

The testgrid-config-generator integration test is failing because of a mismatch between recent code changes and test fixtures:

Recent Code Change (commit 355716a, Mar 3, 2026):

• Updated hardcoded job name prefixes in cmd/testgrid-config-generator/main.go:262-264
• Changed from periodic-ci-openshift-release-master-* → periodic-ci-openshift-release-main-*

Test Fixtures Not Updated:

• Jobs in test/integration/testgrid-config-generator/config/jobs/org/repo/org-repo-master-periodics.yaml still use the old naming:
  • periodic-ci-openshift-release-master-ci-4.10-e2e-aws-ovn-upgrade
  • periodic-ci-openshift-release-master-ci-4.10-upgrade-from-stable-4.9-e2e-aws-ovn-upgrade

Impact:

• These jobs no longer match the prefix check (line 262 in main.go)
• They fail stream detection and return early (line 286-287)
• Expected dashboard files are not generated:
  • redhat-openshift-ocp-release-4.10-blocking.yaml
  • redhat-openshift-ocp-release-4.10-informing.yaml

Expected Behavior

This test failure should affect all PRs currently running against the latest main branch, not just this PR.
