==Investigation 1: Creating a Docker Swarm==

*Install Docker on three virtual machines of your choice.

*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).
