Walkthrough

Workflow refactors Docker image build/push: switches from per-arch matrix and manifest creation to a single buildx build for linux/amd64 and linux/arm64 with metadata-derived tags/labels, full checkout, consolidated registry login, updated actions (build-push v5), and removal of legacy version/env handling and separate manifest jobs.

Poem

I hopped through YAML fields tonight,
Dropped extra matrices from my sight.
Two arches baked in one warm loaf,
Tags from whispers—metadata’s oath.
No manifest maze, just push and go—
Carrots cached? Not anymore—ho ho!
Ship it swift, ears in the flow.
