.github/workflows/docker.ymlusesdocker/metadata-action@v6; the latest v6 release isv6.1.0(May 22, 2026), so@v6will pick up new v6.x changes automatically. v5→v6 includes breaking updates (notably Node 24 runtime requirement on the runner, plus an ESM transition and input-handling/tag behavior changes around#values). Ensure your workflow’sruns-onrunner meets the Node 24 requirement and that tag/label generation still matches expectations with your current inputs.
46-46: Update/buildx-action v4 compatibility check
.github/workflows/docker.ymlusesdocker/setup-buildx-action@v4(line 46). Latest release is v4.1.0 (2026-05-22), so@v4will float across future v4.x updates.v3 → v4 breaking changes to account for:
- Deprecated inputs/outputs removed (can break workflows referencing them)
- Default runtime changed to Node 24 (requires GitHub Actions runner v2.327.1+)
- Implementation switched to ESM (usually internal, but can affect packaging/runtime assumptions)
Verify this workflow doesn’t use any removed/deprecated inputs/outputs and that the GitHub runner version requirement is met; otherwise consider pinning to
v4.1.0(or a commit SHA) for immutability.Snippet

20-20: Update on docker/login-action@v4 (latest + v3→v4 breaking changes)
docker/login-action@v4tracks the latest stable release in the v4 major line (currently v4.2.0). The v3→v4 breaking changes are primarily about the runtime/runner requirements (Node 24 and a newer GitHub Actions runner, mainly relevant to self-hosted/older runners) and internal ESM changes; they don’t introduce new required inputs for this workflow’s usage (username/password, withregistryonly provided on the GHCR login).

🧹 Nitpick | 🔵 Trivial | ⚡ Quick win
Consider pinning actions to commit hashes for supply chain security.
The action reference uses a mutable tag (@v4) rather than a pinned commit SHA. While the Docker organization is generally trusted, pinning to a specific commit hash prevents potential supply chain attacks where a compromised tag could point to malicious code.
🔒 Example: Pin to commit hash
First, find the commit SHA for v4.0.0 (or latest v4.x), then apply:
- uses: docker/login-action@v4
+ uses: docker/login-action@<commit-sha> # v4.x.y
with:
username: ${{ secrets.DOCKERHUB_USERNAME }}
- # Use a Docker Hub Personal Access Token (PAT) for improved security
+ # Use a Docker Hub Personal Access Token (PAT) for improved security

🧩 Analysis chain
🌐 Web query:
What is the latest version of docker/build-push-action and are there breaking changes between v6 and v7?
💡 Result:
As of June 6, 2026, the latest version of docker/build-push-action is v7.2.0 [1]. The transition from v6 to v7 introduced several breaking changes and technical updates [2][3]: 1. Runtime Requirements: v7 upgraded to Node 24 as the default runtime, which requires the GitHub Actions Runner to be v2.327.1 or later [2][3]. 2. Removal of Deprecated Environment Variables: Support for the following environment variables was removed: - DOCKER_BUILD_NO_SUMMARY [2][3] - DOCKER_BUILD_EXPORT_RETENTION_DAYS [2][3] 3. Tooling Changes: Legacy support for the export-build tool (used for build summaries) was removed [2][3]. Additionally, the action switched to ECMAScript Modules (ESM) [2]. If you are upgrading from v6, ensure your runner environment meets the minimum version requirement and check your workflow configuration to ensure you are not relying on the removed environment variables [2].

The Docker build workflow was updated to ensure it uses a Personal Access Token (PAT) for Docker Hub authentication instead of a password. Although the workflow was already using a secret named
DOCKERHUB_TOKEN, I have added a clarifying comment to ensure the secret's purpose is clear. Additionally, I updated all Docker-related GitHub Actions to their latest stable major versions to follow best practices and ensure compatibility. The project build and tests were verified to pass after these changes.PR created automatically by Jules for task 5396846419753865108 started by @Oxygen-Low
