For this exercise, the goal is to create a custom image with the given specifications. We must first initialize LXD with default options. Then, we need to create a container with a CentOS 7 image. Afterwards, we must install and enable Apache web server and MariaDB. Next, we publish our container and create a local image. Lastly, we must create a container from the newly-created image and verify that Apache web server and MariaDB are both running.
Successfully complete this lab by achieving the following learning objectives:
- Initialize LXD and Create a Container with the CentOS 7 Image
Initialize LXD with default options.

- Publish the Container and Create a Local Image
lxc stop our-test-container
lxc publish our-test-container --alias my-new-image
lxc delete our-test-container
- Create a Container from the Newly-Created Image and Verify Apache Web Server and MariaDB are Both Running
