Docker

• Check CRI container run with ID

crictl ps --id 

• Run docker debug

sudo dockerd -H unix:// --debug

• Show disk docker

docker system df

• Clear image

nohup docker system prune -a -f &
docker builder prune --force --filter "until=240h"

• Clear log container or truncate all containers

/var/lib/docker/containers/xxx
truncate -s 0 xxx-json.log.1

• Limit log size with compose

    logging:
      driver: "json-file"
      options:
        max-size: "10m"
        max-file: "3"

• Limit log size with command

docker run -d \
  --log-opt max-size=10m \
  --log-opt max-file=3 \
  abc

• Print docker-compose from container

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock ghcr.io/red5d/docker-autocompose conatainer_name > docker-compose.yml

• Check list socket

sudo netstat -lx | grep docker.sock
