Run Docker Container From Image

Start and create (docker run) an interative (-it) Docker container called copy-example (--name working-directory) from the image called chrisalbon/big-project:working-directory. Open a shell (/bin/bash). Remove the container after it stops (-rm)

docker container run -it --name working-directory chrisalbon/big-project:working-directory /bin/bash

[email protected]:/tmp#

Notice that when the container runs the working directory is tmp
