check / check (push) Successful in 23s
The canonical documents told every repo to exclude .git from the build context, default ARG VERSION to dev and never run git describe in a build stage, so an image built from a clone with no build argument reported dev. .dockerignore now sends .git but keeps out .git/config, which can hold a credential. The Dockerfile example installs git, takes the VERSION build argument when one is given and otherwise git describe --tags --always, and fails when .git exists but the version is empty, dev or unknown. The policy and both checklists state the rule in the same words, including that a plain docker build . with no build arguments must succeed. Model: opus-5-5
