I've found a bug, and:
Description
#370 has broken example documentation from Docker on how one could use the metadata action in a larger workflow to build multi-platform images in GitHub Actions. Specifically, attempting to rename the temporary bake file generated by the metadata action in a follow-up step.
mv "${{ steps.meta.outputs.bake-file }}" "/tmp/bake-meta.json"
https://docs.docker.com/build/ci/github-actions/multi-platform/#with-bake
Attempting to do so now results in an action error like:
Run mv "cwd:///home/runner/work/_temp/docker-actions-toolkit-HBnX10/docker-metadata-action-bake.json" "/tmp/bake-meta.json"
mv: cannot stat 'cwd:///home/runner/work/_temp/docker-actions-toolkit-HBnX10/docker-metadata-action-bake.json': No such file or directory
Error: Process completed with exit code 1.
Expected behaviour
File is found and renamed.
Actual behaviour
File not found.
