About this Hands-on Lab

In this hands-on lab, we are going to use Cockpit to create user accounts and manage the life cycle of a Docker image. The first step will be to log in to Cockpit and create two user accounts in the `Accounts` module. This will be followed by confirming the `Containers` module is installed and then download the container image for testing. The last step will be to use the `Containers` module and simulate a container life cycle using the downloaded image.

Additional Resources

The development team at your company is evaluating Docker as an option to simplify testing environments. The majority of the developers are not familiar with Docker management and have determined they would like to see if Cockpit can manage containers well enough to meet the teams requirements. A server has been provisioned for the project and senior leadership would like to have two developers, Michael Bolton and Samir Nagheenanajar, pilot the Cockpit management process.
