Build Grafana Images

Home-built container images for Grafana and its dashboard sidecar, published to registry.ops.eblu.me/blumeops/.

Grafana

Dockerfile: containers/grafana/Dockerfile Image: registry.ops.eblu.me/blumeops/grafana

Downloads the official Grafana OSS tarball for the target architecture (arm64/amd64), installs it into Alpine, and sets up standard paths.

# Update version in Dockerfile
# ARG CONTAINER_APP_VERSION=12.3.3
 
mise run container-build-and-release grafana

Gotchas:

  • Tarball directory name: Extracts to grafana-<version> (e.g. grafana-12.3.3), not grafana-v<version>.
  • Binary PATH: The binary lives at bin/grafana inside the extracted directory. The Dockerfile sets ENV PATH="/usr/share/grafana/bin:$PATH".
  • UID 472: Matches the official Grafana image for PVC ownership compatibility.

Grafana Sidecar

Build: containers/grafana-sidecar/container.py (native Dagger) Image: registry.ops.eblu.me/blumeops/grafana-sidecar

Clones the kiwigrid/k8s-sidecar source from the forge mirror, installs the Python package into a venv, and copies it into a Python Alpine runtime image.

# Update VERSION in container.py
 
mise run container-build-and-release grafana-sidecar

Gotchas:

  • UID 65534: Matches upstream’s nobody user convention for non-root execution.
  • Forge mirror name: mirrors/kiwigrid-grafana-sidecar (not k8s-sidecar).
  • Health endpoint: 2.x exposes /healthz on port 8080 (liveness + readiness probes configured in deployment).
