# Homelab Artifact Cache

This optional Debian-host stack caches repeated downloads during rebuilds.

- `apt-cacher-ng` on port `3142` for Debian/Ubuntu apt packages
- Docker registry pull-through cache on port `5001` for Docker Hub images

It is intentionally separate from the main homelab pipeline. Start it when you
want faster rebuilds and a little more tolerance for upstream outages.

```bash
cd infra/artifact-cache
docker compose up -d
```

Client examples:

```bash
echo 'Acquire::http::Proxy "http://192.168.100.73:3142";' | sudo tee /etc/apt/apt.conf.d/01homelab-cache
docker pull 192.168.100.73:5001/library/debian:bookworm
```
