From 4Gi to 8Gi to fix OOM during Go compilation, as seen in recent promotion jobs at [1] and [2].

Summary

This PR increases the memory limits used by the OpenShift CI jobs that run for the openshift/openstack-test repository: the wildcard container memory limit (resources['*'].limits.memory) is changed from 4Gi to 8Gi across main and the release branches listed below. The change is intended to address out-of-memory (OOM) failures observed during Go compilation in recent promotion job runs (see referenced failing logs in the PR description).

What changed in practical terms

  • The CI job definitions used by OpenShift's ci-operator for the openshift/openstack-test repository will allocate up to 8Gi of memory per container where the wildcard ('*') resource selector applies, instead of the previous 4Gi.
  • This applies to the main pipeline and the release pipelines used for image builds and promotions—so CI runs for all targeted branches will receive the higher memory limit.
  • No other job behavior, commands, image promotion settings, test/workflow steps, or resource requests were altered.

Files / branches affected

Memory limits were increased in the ci-operator config for:

  • main branch config (openshift-openstack-test-main.yaml)
  • release branches: 4.12 → 4.23
  • future releases: 5.0, 5.1

(All changes are the same: resources['*'].limits.memory: 4Gi → 8Gi.)

Impact

  • CI jobs for openshift/openstack-test will have double the memory headroom for build/compile steps (notably Go compilation), reducing OOM-related failures during promotions and image builds.
  • No change to resource requests means scheduling behavior may be unchanged; only the allowed limit is increased.

@mandre, pj-rehearse: unable to determine affected jobs. This could be due to a branch that needs to be rebased. ERROR:
