Manage external Juju controllers

Register the Juju controller

As a prerequisite, perform the following steps in existing Juju controller

• Add a Juju user.
• Grant necessary permissions to the Juju user.

Adding the Juju user will generate a registration token which is required to register the Juju controller in the MicroStack deployment.

To register the controller in MicroStack use the register-controller command:

sunbeam juju register-controller NAME TOKEN

NAME is an arbitrary name to refer the Juju controller in MicroStack.

TOKEN is the registration token generated during Juju user creation.

For example, to register an existing controller with the name prod-controller-01 using a token generated as detailed above:

sunbeam juju register-controller prod-controller-01 \
