Continuing in our series on CLI-only MAAS operation, it’s time to deploy machines. In the previous post, we reached the point of creating and commissioning machines, using only the MAAS CLI. Moving forward, there are two key steps: acquiring machines, and then deploying them. Let’s take a look
Acquiring a machine using the CLI
When a machine has finished commissioning,we can acquire it like this:
stormrider@wintermute:~$ maas admin machines allocate \
system_id=bhxws3If you correctly enter this command — substituting your own machine’s system ID for the bhxws3shown here — you should get JSON output similar to this:
Success.
Machine-readable output follows:

}Acquisition is a simple step, but it executes the key operation of associating your user with the machine in question, which gives you control of that resource. Once you’ve acquired a machine, deployment is the next step.
Deploying a machine with the CLI
Finally, we can deploy the machine this way:
stormrider@wintermute:~$ maas admin machine deploy bhxws3Again, if you’ve properly entered the command and correctly substituted your machine’s system ID, you should get JSON that looks something like this:
Success.
