Ship a distroless image so the plugin can run in-cluster in serve mode,
letting developer laptops use the shared cache without S3 credentials.
- Dockerfile: golang builder running `make build`, distroless static nonroot
- `make docker` for a local smoke build
- `.woodpecker/docker.yaml` pushes to docker-internal on tag
- README: image name and the SSL_CERT_DIR mount the internal CA needs
Upstream publishes no releases, so CI has nothing to curl.
- pin cmd/go-cache-plugin at 3031b5d via the go.mod tool directive
- build a static stripped binary with make build
- test the built binary: static ELF, pinned provenance, and a real
go build driven through it as a GOCACHEPROG against a stub S3
- add PR build/test/pre-commit workflows and a tag release workflow
attaching linux/amd64 and linux/arm64 to a Gitea release
