Any block on mcr.microsoft.com or docker.io from KZ would stall our
builds. Mirror docker base images into 127.0.0.1:5001 under mirror/*
via daily systemd timer, and point Dockerfiles + compose + CI at the
local copies.
Mirror:
node:20-alpine → 127.0.0.1:5001/mirror/node:20-alpine
nginx:1.27-alpine → 127.0.0.1:5001/mirror/nginx:1.27-alpine
postgres:16-alpine → 127.0.0.1:5001/mirror/postgres:16-alpine
mcr.microsoft.com/dotnet/sdk:8.0 → 127.0.0.1:5001/mirror/dotnet-sdk:8.0
mcr.microsoft.com/dotnet/aspnet:8.0 → 127.0.0.1:5001/mirror/dotnet-aspnet:8.0
Infra (committed for reproducibility):
- deploy/mirror-base-images.sh — pull/tag/push (idempotent)
- deploy/food-market-mirror-base-images.{service,timer} — daily refresh,
installed on stage server
Usage in build-time:
- Dockerfile.api/web take ARG LOCAL_REGISTRY=127.0.0.1:5001 with the local
copy as default, so the same Dockerfile still builds from docker.io if
you pass --build-arg LOCAL_REGISTRY=docker.io (well, almost).
- docker-compose.yml postgres: image via ${REGISTRY}/mirror/postgres.
- ci.yml postgres service container: local mirror.
