docker prometheus

cadvisor 與 Prometheus 的完美結合，所以它成爲了容器監控的第一選擇

docker pull google/cadvisor:latest

docker images

sudo docker run \
  --volume=/:/rootfs:ro \
  --volume=/var/run:/var/run:rw \
  --volume=/sys:/sys:ro \
  --volume=/var/lib/docker/:/var/lib/docker:ro \
  --volume=/dev/disk/:/dev/disk:ro \
  --publish=8080:8080 \
  --detach=true \
  --name=cadvisor \
  google/cadvisor:latest

docker ps
