Working with LXD Containers

LXD, or the Linux Container Daemon, lets us leverage the resource-lite LXC virtualization method, as well as providing additional support for the container images we use to spin up our containers. In this lab, we'll be creating a test LAMP stack by setting up two containers: one for our website and one for a database. Note the lab has been updated with a more recent alpine/edge image as alpine/3.10 is no longer available.
