Repackages gcr.io/cadvisor/cadvisor as a versioned, buildable image + compose service.

• Dockerfile → static metadata (Prometheus scrape labels).
• docker-compose.yml → everything host-specific.

Prerequisites

The traefik (or whatever you name it via WEB_NET) Docker network must already exist, e.g.:

docker network create --driver bridge --subnet 172.31.0.0/16 traefik

Usage

docker compose up -d --build

or

docker run -d \
  --name cadvisor \
  --restart unless-stopped \
  --privileged \
  --network traefik \
  --device /dev/kmsg \
  --label prometheus_address=cadvisor:8080 \
  --label prometheus_scrape=true \
  -v /:/rootfs:ro \
  -v /var/run:/var/run:rw \
  -v /sys:/sys:ro \
  -v /var/lib/docker:/var/lib/docker:ro \
  --log-driver syslog \
  --log-opt syslog-address=udp://127.0.0.1:5514 \
  --log-opt tag="{{.Name}}" \
  ghcr.io/saashup/cadvisor:latest

Metrics are exposed on the container's :8080/metrics, reachable from other containers on the same network as http://cadvisor:8080/metrics.
