+## CI/CD & Deployment
+
+- CI workflow: `.gitea/workflows/ci.yml` — build → docker → deploy on push to main
+- Build step skips integration tests (`-DskipITs`) — Testcontainers needs Docker daemon
+- Docker: multi-stage build (`Dockerfile`), `$BUILDPLATFORM` for native Maven on ARM64 runner, amd64 runtime
+- `REGISTRY_TOKEN` build arg required for `cameleer3-common` dependency resolution
+- Registry: `gitea.siegeln.net/cameleer/cameleer3-server` (container images)
+- K8s manifests in `deploy/` — ClickHouse StatefulSet + server Deployment + NodePort Service (30081)
+- Deployment target: k3s at 192.168.50.86, namespace `cameleer`
+- Secrets managed in CI deploy step (idempotent `--dry-run=client | kubectl apply`)
+- Docker build uses buildx registry cache + `--provenance=false` for Gitea compatibility
