55-63: Confirm v6 input/output parity & pin digest for reproducibility
docker/build-push-actionv6 removes some deprecated inputs and introduces new defaults (e.g.,load: trueauto-loads images). The currentwith:block (file,push,tags) is still supported, but please double-check the v6 release notes to ensure no silent behaviour changes affect this workflow.
For supply-chain stability, consider pinning to the major tag + digest, e.g.docker/build-push-action@v6@sha256:<digest>..github/workflows/devcontainer-ti.yaml (1)
55-63: Same v6 compatibility & digest pinning considerationsReplicate the v6 release-notes check and digest pinning suggestion here to maintain consistent, reproducible builds across all dev-container workflows.
.github/workflows/devcontainer-azurertos.yaml (1)
55-63: Validate behaviour change after upgrading to v6Ensure
push: trueand tag handling behave exactly as before; v6 tweaks cache-related defaults that could impact build time or registry content. Pin to a digest for immutability if possible..github/workflows/devcontainer-esp32.yml (1)
55-63: Upgrade sanity-check and optional digest pinConfirm no deprecated inputs (e.g.,
context,platforms) are implicitly relied upon. Consider locking the action to@v6@sha256:<digest>to avoid unexpected future changes..github/workflows/devcontainer-chibios.yaml (1)
55-63: Consistency check after bump to v6Double-check the ChibiOS image still builds & pushes as expected with the new major version and apply digest pinning for deterministic CI runs.
.github/workflows/devcontainer-freertos-nxp.yaml (1)
55-57: Verify v6 migration settings (provenance,sbom, cache) before merging
docker/build-push-action@v6introduces new defaults (provenance: true,sbom: true, different cache-from/to syntax).
If you don’t explicitly want provenance/SBOM generation or intend to keep the current cache behaviour, add the relevant inputs:- - name: Build and Push Docker Image - uses: docker/build-push-action@v6 + - name: Build and Push Docker Image + uses: docker/build-push-action@v6 + with: + provenance: false # disable SLSA attestation if not required + sbom: false # disable SBOM upload if not required + # cache-from / cache-to examples: + # cache-from: type=registry,ref=${{ env.CONTAINER_REPO }}/...:cache + # cache-to: type=registry,ref=${{ env.CONTAINER_REPO }}/...:cache,mode=max(Or keep them enabled deliberately—just make the choice explicit.)
Also consider pinning to a full semver tag or SHA for supply-chain safety, e.g.
docker/[email protected].

62-64: Multi-tag push strategy is idiomatic. The workflow now pushes both a versioned tag (${{ env.GCR_VERSION }}) andlatest, which is a standard pattern for container images and maintains backward compatibility for consumers relying on thelatesttag.All referenced environment variables are properly defined (lines 6–9) and the
GCR_VERSIONis populated dynamically in the prior step (lines 39–45).

62-64: Clarify tags format: prefer explicit single-line CSV over YAML folded scalar.The current YAML
>(folded scalar) converts the multi-line block into a single line with spaces:"ghcr.io/owner/name:version, ghcr.io/owner/name:latest". While this produces valid CSV, the non-standard presentation and reliance on YAML's implicit folding behavior makes it less clear and potentially fragile.Recommendation: Replace the folded scalar with an explicit single-line CSV string for clarity and consistency with standard GitHub Actions patterns.

Resolve prior critical flag by refactoring to explicit single-line CSV.
A previous review flagged this tags format as incompatible with docker/build-push-action@v6, requiring CSV format. Docker/build-push-action expects a comma-delimited list of tags. The current YAML > (folded scalar) does produce a single-line CSV string, but using the standard explicit format will eliminate ambiguity and definitively resolve the prior concern.

🧩 Analysis chain
🌐 Web query:
docker build-push-action v6 tags input format YAML
💡 Result:
Short answer: the v6 action accepts tags as either a comma-separated list or a YAML multiline string (pipe |) with one tag per line — and it also accepts the metadata-action output (steps.meta.outputs.tags). Examples:
-
comma-separated:
tags: "v1,latest,sha-abc123". [1][2] -
YAML multiline (recommended for readability / expressions):
tags: |
ghcr.io/my-org/my-app:latest
ghcr.io/my-org/my-app:${{ github.ref_name }}. [3][4] -
using docker/metadata-action output:
tags: ${{ steps.meta.outputs.tags }} (metadata-action produces the tags string that build-push-action consumes). [4][5]
Sources: Docker Build & Push Action docs / GitHub Marketplace and Docker docs on GitHub Actions (examples above). [1][2][3][4][5]

@networkfusion, You're absolutely right to prioritize readability. The folded scalar (>) format you're using is valid for docker/build-push-action@v6.
If you'd like an even more readable option, the Docker documentation actually recommends using the pipe (|) format with one tag per line:
tags: |
${{ env.CONTAINER_REPO }}/${{ github.repository_owner }}/${{ env.CONTAINER_NAME }}:${{ env.GCR_VERSION }}
${{ env.CONTAINER_REPO }}/${{ github.repository_owner }}/${{ env.CONTAINER_NAME }}:latestThis format is clearer than the folded scalar and avoids the trailing comma. However, your current format works correctly, so this is purely a readability suggestion—no change is required.

@networkfusion, Yes, you're absolutely right—the original pipe (|) format was correct for docker/build-push-action@v6. I apologize for the initial incorrect flag suggesting it was incompatible.
To clarify the changes in this PR:
- Original format: Used pipe (
|) with only the GCR_VERSION tag - New format: Uses folded scalar (
>) with both the GCR_VERSION tag AND a new "latest" tag
Both the pipe (|) and folded scalar (>) formats are valid and work correctly with docker/build-push-action@v6. The substantive change here is the addition of the "latest" tag, not the format itself. The format change from | to > is inconsequential—either works fine.
Sorry for the confusion caused by the initial review comment.

You are wrong. The original implementation included 2 tags (including latest).
There was a problem hiding this comment.
@networkfusion, You're absolutely correct, and I apologize for the error. Looking at the diff more carefully, the :latest tag was indeed present in the original implementation. The line without a - or + prefix indicates it existed in both versions.
The actual change in this PR is:
- Original format: Used pipe (
|) with both the GCR_VERSION tag AND the latest tag (two separate lines) - New format: Uses folded scalar (
>) with the same two tags, but with a comma separator
Both the original and new formats are valid for docker/build-push-action@v6. The change is purely in the YAML formatting approach, not in which tags are being pushed.
Thank you for the correction, and I apologize for the confusion in my previous responses.
