Using a MAAS cloud

Juju works closely with MAAS to deliver the same experience on bare metal that you would get by using any other cloud. Note that the Juju 2.x series is compatible with both the 1.x and 2.x series of MAAS.

Registering a MAAS cloud with Juju

Using the Juju add-cloud command, it is easy to add your MAAS clouds to Juju's list of known clouds. The command is interactive, and will ask for a name and the endpoint to use. A sample session is shown below.


juju add-cloud

...will enter the interactive mode. Enter the desired values to continue.

Cloud Types

Select cloud type: maas

Enter a name for your maas cloud: mainmaas

Enter the API endpoint url:

Cloud "mainmaas" successfully added
You may bootstrap with 'juju bootstrap mainmaas'

This will add both the 'mainmaas' cloud, which you can confirm by running:

juju clouds

This will list the newly added clouds, preceded with the prefix 'local:' which denotes that these are local clouds added by the user:

Cloud        Regions  Default        Type        Description
aws               11  us-east-1      ec2         Amazon Web Services
mainmaas            0                 maas        Metal As A Service

Before you bootstrap this cloud, it is necessary to add the relevant credentials, as explained below.

Adding your MAAS credentials

juju add-credential mainmaas

When prompted for "maas-oauth", you should paste your MAAS API key. Your API key can be found in the Account/User Preferences page in the MAAS web interface, or by using the MAAS CLI:

sudo maas-region apikey --username=<user>

Note: Juju does not echo this key back to the screen.

Now you can create a Juju controller with the bootstrap command:

juju bootstrap mainmaas mainmaas-controller

Above, the Juju controller was called 'mainmaas-controller'.

Manually defining MAAS clouds

If for any reason you would rather define all your MAAS clouds in a single YAML configuration file, Juju can also import cloud definitions. For more details on this, see the documentation on manually adding MAAS clouds
