This will display the version of docker in use.


$ docker info

This will display comprehensive information about your docker installation, including how many images and containers there are, and lots of othe information, including the Docker version.


$ docker attach container_name

 This command will reconnect you to an interactive session, if one exists on your container.


$ docker run hello-world

This will test the Docker configuration, by pulling the 'hello-world' image and running it once as a container, giving some very succinct output.


$ docker image ls

This will list all current images available to this Docker host (e.g. including hello-world, if you've run the previous command).


$ docker container ls -all

Lists all containers, including ones that have run since this Docker host was last started up.


$ docker ps

This will list all running containers. Adding an -a flag lists all containers, both stopped and running.


$ sudo docker stop $(sudo docker ps -a -q)

This will stop all containers.


$ sudo docker rm -f $(sudo docker ps -a -q)

This will forcibly remove all containers
