I am trying out MaaS and Juju for the first time and have run
into a couple of questions that I haven't been able to find
answers to in the documentation or by searching.
My setup is as follows: One server installed from scratch with
the "create maas server" option on the 12.04 server cdrom and
two nodes that PXE boot from the MaaS server.
1. I have the two nodes able to be started from the MaaS
webinterface with WoL. However, once they are booted I have been
unable to find a way of shutting them down or rebooting them
except by physically walking up to them and pressing the power
button or ctrl-alt-delete. Is there no remote way of doing this?
2. In continuance of Q1, I have added my SSH public key in
the MaaS webinterface, but I have been unable to login to any of
the nodes over SSH. Are there no accounts enabled on MaaS nodes?
(this would enable remote shutdown/reboot)
3. I have setup ~/.juju/environments.yaml according to the
MaaS guide with the OAuth key for my MaaS user. When I run 'juju
bootstrap' it seems to work, but 'juju status' only shows one
machine. In the MaaS webinterface it says that one of the nodes
is allocated to my user, the other still says 'Ready'. How do I
get both machines to be available for deployment of juju charms?
4. If I later want to add more nodes, will I need to do a new
bootstrap to have them available to juju or is there a way to

1. You can login into the server with the ssh option of juju.
Therefore your SSH key must be already imported into the node.
2. How have you installed the nodes? Normally the SSH key is added
when you bootstrap the juju environment and install the node.
3. If you do 'juju bootstrap', one of the nodes will be dedicated to
juju, and will be used to launch and orchestrate other instances.
When you add, for example, a node for MySQL 'juju deploy mysql',
another node will be allocated to your user account.
4. You don't have to bootstrap again. When your node's are ready,
you can deploy a charm to it.
Again, how did you install the MAAS invironment?
I use the next steps.
1. Installer the maas server with the "create maas server" option
(also create superuser and install maas-dhcp)
2. create a ssh key for the user
3. import the ssh key into maas
4. create the file ~/.juju/environments.yaml' with the correct
5. Add the nodes to the maas webinterface. This will boot the
servers (WOL) with the ephemeral boot image, after a short while
(maybe a minute), the server will automatically shutdown and the
status of the server will be ready in the webinterface.
6. do 'juju bootstrap', this will boot one of the nodes by WOL and
start a installation of ubuntu. It will also import you SSH key into
7. do 'juju deploy mysql', this will boot another node by WOL ans
start a installation of ubuntu including MySQL and will also import
you SSH key.
