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 Docker build setup across release, post-merge, and pull request validation workflows.
    • 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

The pull request replaces Docker’s Buildx setup action with the organization-specific action in three GitHub workflows. All other workflow behavior remains unchanged.

Changes

Buildx action standardization

Layer / File(s) Summary
Update workflow Buildx setup
.github/workflows/dispatch-alpha-release.yml, .github/workflows/post-merge.yml, .github/workflows/pull-request-status-check.yml
The workflows now use gooddata/github-actions/docker/setup-buildx@master instead of docker/setup-buildx-action@v3.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: 🔵 Low · up to d4f99

This PR switches three workflows to a shared Buildx wrapper, but references it through mutable @master. The change is mergeable with owner follow-up to pin an immutable revision so future wrapper changes cannot silently alter CI behavior.

Poem

A rabbit checks the buildx trail
Three workflows now share the rail
The Docker step wears a local name
The rest of the flow remains the same
Builds hop onward, neat and bright

Pin the shared Buildx wrapper to an immutable revision.

All three workflows use the mutable @master reference. Replace each reference with a full-length commit SHA and record its version in a comment.
