Build image:

    docker images
    docker build --tag gs3-tomcat .
    docker images

Spin up a running container:

    docker run -d --name this-gs3-tomcat -p 8383:8383 gs3-tomcat

    docker ps

Execute an interactive bash session on the container:

    docker exec -it this-gs3-tomcat /bin/bash




To cleanly remove an image:

    docker ps --all

Delete all known instances:

    docker rm <container-name1> <container-name2> ...

Now you can delete the image:

    docker rmi <image-name>
