Inside our running container let's add the `json` gem.
Inside our running container first let's update Ruby:
root@0b2616b0e5a8:/# gem install json
root@0b2616b0e5a8:/# apt-get install -y ruby2.0-dev
Now let's add the `json` gem.
root@0b2616b0e5a8:/# gem2.0 install json
Once this has completed let's exit our container using the `exit`
command.
