What

Replace docker/setup-buildx-action@v3 with the shared wrapper
gooddata/github-actions/docker/setup-buildx at 3 call site(s). No inputs
were being passed, so this is a one-line swap per site.

Why

Two things come with the wrapper:

  • buildkit is pulled from the ECR pullthrough cache rather than Docker Hub
    through the NAT gateway
  • the buildx builder is created inside the runner pod's cgroup instead of
    /docker/buildx, so Kubernetes can account for the build

Impact

  • no resource limits change; runner pod slices carry no ceiling today, so
    nothing starts being enforced
  • the cgroup behaviour is a no-op on GitHub-hosted runners and on drivers
    other than docker-container

Depends on gooddata/github-actions#417 (wrapper default off to auto).
Merging this before that one is harmless, it just does not re-parent yet.

JIRA: INFRA-4816

Summary by CodeRabbit

  • Chores
    • Updated release, post-merge, and pull request validation workflows to use the standardized Docker build setup.
    • Existing workflow behavior remains unchanged.

- swap docker/setup-buildx-action@v3 for
  gooddata/github-actions/docker/setup-buildx
- pulls buildkit from the ECR pullthrough cache instead of Docker Hub
  through the NAT gateway
- brings the builder into the runner pod cgroup, so its CPU and memory
  show up in pod metrics instead of being invisible

Review Change Stack

📝 Walkthrough

Walkthrough

Three GitHub Actions workflows replace docker/setup-buildx-action@v3 with gooddata/github-actions/docker/setup-buildx@master. Other workflow behavior remains unchanged.

Changes

Buildx action standardization

Layer / File(s) Summary
Workflow Buildx setup
.github/workflows/dispatch-alpha-release.yml, .github/workflows/post-merge.yml, .github/workflows/pull-request-status-check.yml
The release, post-merge, and pull-request status workflows now use the organization-specific Docker Buildx setup action.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to 75683

The migration is otherwise localized, but the shared action is referenced through a mutable branch, so future updates could change CI or release behavior without a reviewed change. The PR is mergeable with explicit owner follow-up to pin one reviewed commit at all three sites.

Poem

A rabbit checks the buildx trail
Three workflows follow the same rail
Alpha hops, post-merge too
Status checks use the action anew
The build steps stay steady and true

Pin the shared Buildx action to one reviewed commit.

All three workflows use gooddata/github-actions/docker/setup-buildx@master. A later branch update can change release and pull-request runner behavior. Use the same reviewed full commit SHA at all three call sites.
