Create a Custom Image with the Given Specifications

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.
