init-envsubst

Tiny K8s init-container helper. Alpine 3.21 with envsubst, curl, jq, ca-certificates baked in.

Why

Drop-in replacement for alpine:3.X init containers that run apk add --no-cache gettext at startup. Eliminates the network dependency on dl-cdn.alpinelinux.org at pod start time.

Use

initContainers:
  - name: config-init
    image: ghcr.io/oddie-apps/init-envsubst:latest
    command: [sh, -c, "envsubst < /src/config.yaml > /dst/config.yaml"]

Tags

  • latest — current alpine 3.21 build
  • alpine-3.21 — pinned to alpine 3.21
  • <git-sha> — immutable per commit

Build cadence

CI rebuilds on push, manual dispatch, or weekly (Mondays 06:00 UTC) to pick up alpine package patches.
