General Usage

• Start a container in the background:

    $ docker run -d jenkins
  

• Start an interactive container:

    $ docker run -it ubuntu bash
  

• Export port from a container:

    $ docker run -p 80:80 -d nginx
  

• Start a named container:

    $ docker run --name mydb redis
  

• Restart a stopped container:

    $ docker start mydb
  

• Stop a container:

    $ docker stop mydb
  

• Add metadata to a container:

    $ docker run -d --label=traefik.backend=jenkins jenkins
  

Build Images

• Build an image from Dockerfile in the current directory:

    $ docker build --tag myimage .
  

• Force rebuild of a Docker image:

    $ docker build --no-cache .
  

• Convert a container to an image:

    $ docker commit c7337 myimage
  

Debug

• Run another process in a running container:

    $ docker exec -it c7337 bash
  

• Show live logs of a running daemon container:

    $ docker logs -f c7337
  

• Show exposed ports of a container:

    $ docker port c7337
  

Volumes

• Create a local volume:

    $ docker volume create --name myvol
  

• Mounting a volume on container start:

    $ docker run -v myvol:/data redis
  

• Destroy a volume:

    $ docker volume rm myvol
  

• List volumes:

    $ docker volume ls
  

Manage Containers

• List running containers:

    $ docker ps
  

• List all containers (running & stopped):

    $ docker ps -a
  

• Delete all stopped containers:

    $ docker rm $(docker ps --filter status=exited -q)
  

• Start a container automatically removed on stop:

    $ docker run --rm ubuntu bash
  

• Query a specific metadata of a running container:

    $ docker inspect -f '{{ .NetworkSettings.IPAddress }}' c7337
  

Networking

• Create a local network:

    $ docker network create mynet
  

• Attach a container to a network on start:

    $ docker run -d --net mynet redis
  

• Connect a running container to a network:

    $ docker network connect mynet c7337
  

• Disconnect a container from a network:

    $ docker network disconnect mynet c7337
  

• List all containers with a specific label:

    $ docker ps --filter label=traefik.backend
  

Cleanup

• Remove all unused images:

    $ docker rmi $(docker images -q)
