ci: use the shared setup-buildx wrapper - #21
Conversation
- 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 JIRA: INFRA-4816 risk: nonprod

GitHub Actions secure use pin actions to full length commit SHA mutable tag branch official documentation
💡 Result:
To secure GitHub Actions, it is recommended to pin actions to a full-length (40-character) commit SHA rather than a mutable tag or branch [1][2][3]. Pinning to a full-length SHA ensures that the exact, immutable version of the code is executed, preventing attackers from injecting malicious code into existing tags or branches that your workflow might otherwise automatically pull and run [4][3][5]. Key points for implementing SHA pinning: 1. Use Full-Length Commit SHAs: Always use the complete 40-character SHA [6][7]. Abbreviated SHAs are not recommended and may not be accepted by all security policies [7]. 2. Maintain Human Readability: A common best practice is to include the human-readable version tag as a comment in the workflow file (e.g., uses: actions/checkout@3df4ab1 # v4.0.0) [3][6][5]. This makes the workflow easier to understand and allows tools like Dependabot or Renovate to track and suggest updates [8][9][5]. 3. Automate Updates: Pinning does not mean you stop receiving updates. You can configure dependency management tools such as Dependabot or Renovate to monitor the referenced action's repository and open pull requests that update the SHA and the version comment automatically [8][9][5]. 4. Enforce via Policies: GitHub allows organization and repository administrators to enforce SHA pinning through Actions policies [1][10]. When enabled, any workflow that attempts to use a mutable reference (like a tag or branch) will fail, ensuring compliance across the organization [10][8][5]. 5. Security Context: While SHA pinning is the most secure option, GitHub still recommends that you only trust actions from creators you know [1][2]. The "Verified creator" badge on the GitHub Marketplace is one indicator of trustworthiness, but SHA pinning remains the primary defense against supply-chain attacks where a valid action repository is compromised [1][2][5]. Official documentation emphasizes that pinning to a full-length commit SHA is currently the only way to treat an action dependency as an immutable release [1][2].

Pin the shared Buildx action to an immutable commit SHA.
All three workflows use gooddata/github-actions/docker/setup-buildx@master. Replace @master with the same verified 40-character commit SHA in all three locations. Do not use an unverified SHA.

What
Replace
docker/setup-buildx-action@v3with the shared wrappergooddata/github-actions/docker/setup-buildxat 3 call site(s). No inputswere being passed, so this is a one-line swap per site.
Why
Two things come with the wrapper:
through the NAT gateway
/docker/buildx, so Kubernetes can account for the buildImpact
nothing starts being enforced
other than
docker-containerDepends on gooddata/github-actions#417 (wrapper default
offtoauto).Merging this before that one is harmless, it just does not re-parent yet.
