## Summary - Add two-stage Dockerfile for Loki (Go build → Alpine runtime) in `containers/loki/` - Rewrite kustomize image to `registry.ops.eblu.me/blumeops/loki` - Tag is `v3.6.5-placeholder` until first CI build; will be updated post-build ## Details - UID 10001 matches existing StatefulSet `securityContext` (runAsUser/fsGroup) - CGO_ENABLED=0, ldflags embed version via `github.com/grafana/loki/v3/pkg/util/build` - Clones from `forge.ops.eblu.me/mirrors/loki` (mirror created this session) - Pattern follows miniflux (two-stage Go) + prometheus (ldflags) ## Deployment and Testing - [ ] Trigger container build: `mise run container-build-and-release loki` - [ ] Update kustomize tag to actual build tag - [ ] Deploy from branch: `argocd app set loki --revision feature/loki-container && argocd app sync loki` - [ ] Verify `/ready` endpoint and log ingestion - [ ] After merge: update to `[main]` tag (C0 follow-up) Reviewed-on: #280
