A DNS name like *.home.hrajfrisbee.cz put "*" into the listener name; the
API server rejected the patch, which blocked every certificate on that
Gateway.
- lowercase the DNS part, spell "*" as "wildcard", map other characters
outside [a-z0-9] to "-"
- names over 253 chars are cut and get a hash suffix instead of a blind cut
- names that were valid before are unchanged

- ci: reject a manual dispatch with tag "latest"; concurrency group per tag
- Dockerfile: declare GIT_COMMIT after the module download layer
- Makefile: docker-build targets linux/amd64 by default
- patch.go: no shared package-level pointers; main.go: no init()
- tests: assert that merge replaces managed listener content
- docs: flows.md startup section matches main.go; review saved to docs/reviews

- check job runs go vet, go build and go test -short before the build
- images are pushed as :<tag> and :sha-<12>; :latest moves only on tag pushes
- GIT_COMMIT build arg and OCI source/created labels

Covers current correct behaviour of the pure functions in internal/gateway.
Known-buggy inputs (wildcards, collisions, truncation) are left out on purpose.

- module path is now gitea.home.hrajfrisbee.cz/kacerr/gatewayapi-certificates-operator
- internal/version resolves the commit from ldflags or Go build info;
--version prints it and the first log line carries it
- --metrics-bind-address is passed to the manager instead of being dropped
- Dockerfile takes GIT_COMMIT, honours TARGETARCH, labels the image revision

- make check runs lint + vet + test-short; lint is pinned to the go.mod
toolchain so it works when the host Go is newer than golangci-lint's
- gofumpt main.go and patch.go; drop unused gatewayGroup/gatewayKind vars

- /ship now commits and pushes with a branch guard and no longer tags;
/release tags vMAJOR.MINOR.PATCH and confirms before pushing
- operator-reviewer and go-operator-reviewer agents from egress-proxies-operator
- committed permission allowlist; settings.local.json ignored

- CLAUDE.md in five sections with Go, testing, plan, changelog, branching
and tagging rules; known sharp edges moved to Gotchas
- docs/flows.md: metrics are served on :8080, name collisions are rejected
by the API server, last-cert deletion never cleans up
- README moved to the repo root, deploy command corrected

Adds kustomization.yaml to enforce explicit resource ordering
(namespace before deployment/service). Updates CI to use
kubectl apply -k instead of kubectl apply -f.

Add build and kubernetes-deploy Gitea Actions workflows, and split deploy/manifests.yaml into individual manifest files.

Kubernetes operator that automates HTTPS listener configuration on
Gateway API Gateway resources whenever a cert-manager Certificate is
created or updated.
Core behaviour:
- Watches cert-manager Certificate resources for the annotation
gateway-cert-operator.io/gateway-name to identify the target Gateway
- Builds HTTPS listeners (prefixed "auto-") from each Certificate's
DNS SANs and merges them into the target Gateway's listener list
- Preserves any manually-managed listeners; removes stale auto-listeners
when Certificates are deleted or their annotations are removed
- Supports optional annotations to override the target namespace and
listener port (default 443)
Components:
- main.go – manager setup, scheme registration,
health/readiness probes
- internal/controller/ – Certificate reconciler with field
indexing and dual-watch pattern
- internal/gateway/patch.go – listener construction, merge, and
equality helpers
- deploy/manifests.yaml – Namespace, RBAC, and Deployment
- docs/README.md – usage guide and architecture notes
- Dockerfile – distroless multi-stage build
