==Investigation 1: Creating a Docker Swarm==
*Install Docker on three virtual machines of your choice.
**'''Note: ''' Do not use Docker on your host, as it may interfere with other services covered in this course.**'''Note2:''' Do not install Docker from the default CentOS repository! Refer to your lecture notes and slides for the correct method.
*Pick one of your machines to be the swarm manager, start a swarm on it, and make the others join the swarm as nodes.
==Investigation 2: Deploying an image across the swarm==
*Run a container using the existing image for httpd and make some changes to the index.html file by using docker exec (The exact content is not important just include some text that says ‘version 1’, I just want to see that you can modify it).
*Write a compose file that will deploy one copy of your container onto each of your machines.
==Submission==
