You need to commit the changes you make to the container and then run it. Try this:
sudo docker pull ubuntu
sudo docker run ubuntu apt-get install -y ping
Then get the container id using this command:
sudo docker ps -l
Commit changes to the container:
sudo docker commit <container_id> iman/ping
Then run the container:
sudo docker run iman/ping ping www.google.com</nowiki>
