05 - Deploying machines

When it's finished commissioning, I can acquire a machine like this:

Having once acquired the machine, which basically gives my username control, I can deploy the machine this way:

Okay, done with that much. I have installed and configured MAAS, started DHCP, created a machine, commissioned it, acquired it, and deployed it without touching the UI. Next, I'm going to get a large number of machines online – both LXD VMs and libvirt VMs – and see if I can do a little jq magic to get some more human-readable output from the MAAS CLI.
