Closes wind-c#137. This change adds three deliverables: 1. A maintained Helm chart at deploy/helm/comqtt supporting both single-node (Deployment) and clustered (StatefulSet + Raft + Gossip) modes. The chart includes: - values.schema.json with conditional rules (cluster mode requires odd replicaCount and persistence.enabled=true) - A runtime entrypoint shim that renders the broker config from a ConfigMap template, computing seed members from replicaCount + the headless Service FQDN, and enabling --raft-bootstrap only when both pod-0 AND the Raft data dir is empty (idempotent on restart) - PodDisruptionBudget pinned to Raft quorum (ceil((n+1)/2)) - Soft pod anti-affinity by default; hard via cluster.hardAntiAffinity - Per-replica PVCs via volumeClaimTemplates - liveness, readiness, and startup probes (all tunable) - Optional dashboard Ingress with documented MQTT-TCP caveats - Optional ServiceMonitor for kube-prometheus-stack - helm test pod that performs a mosquitto pub/sub round trip - chart README with full values reference, upgrade notes, and limitations (no operator, no automatic Raft member eviction) 2. .goreleaser.yaml building cmd/single + cmd/cluster across linux, darwin, windows × amd64, arm64. Builds multi-arch (amd64 + arm64) Docker images via goreleaser dockers + docker_manifests, publishing to ghcr.io/wind-c/comqtt with semver, minor, and latest tags. 3. .github/workflows/{release,chart-lint-test,chart-release}.yaml: - release.yaml triggers on tag push, runs GoReleaser, publishes binaries to GitHub Releases and images to GHCR - chart-lint-test runs ct lint + helm template + a kind boot test across single and cluster CI value files - chart-release runs helm/chart-releaser-action on push to main Implementation note: cmd/cluster/main.go replaces all CLI flag values with the loaded --conf file when one is supplied, so passing --raft-bootstrap as a CLI flag alongside --conf is silently ignored. The chart works around this by templating the config file itself at runtime via the entrypoint shim. Bitnami sub-charts (Redis/MySQL/Postgres) are intentionally NOT bundled because the public bitnami/* Docker images now require authentication. The chart documents bring-your-own and ships an example Valkey manifest at deploy/helm/comqtt/ci/valkey.yaml as the recommended OSS RESP store. Verification gauntlet (all passed locally on kind v0.31.0): - helm lint deploy/helm/comqtt - helm template (single + cluster) - kubectl --dry-run=client apply - helm install single + helm test (MQTT pub/sub round trip) - helm install cluster (3-node Raft, leader election + member join) - Cross-node MQTT: subscribe on cluster-comqtt-0, publish to cluster-comqtt-2, message delivered via shared Valkey state - Bootstrap idempotency: kubectl delete pod cluster-comqtt-0 -> "genesis pod but raft dir is non-empty; bootstrap suppressed"
