juju openstack-base guide is not clear

[Junaid Ali]

Hi Yinon,

I would suggest you to read https://jujucharms.com/do
cs/stable/getting-started
and
https://docs.ubuntu.com/maas/2.1/en/

MAAS will provision the nodes. If you check the bundle.yaml file, it has a
machine section in it where Juju has specified some machines to be
provisioned by MAAS. You should probably look for Juju constraints
<https://jujucharms.com/docs/2.0/charms-constraints>

Yes, PXE, management are mapped onto the same network (eth0). You can
use network
spaces <https://jujucharms.com/docs/stable/network-spaces> feature of Juju
to use different APIs on different networks but I think the commands in the
shared link need update.

You can deploy the cloud using bundle.yaml by simply running:
$ juju deploy bundle.yaml

Question: Where do I specify the IPs of the target hosts, or the MAAS

Machines will be provisioned by MAAS using the constraints (and series)
specified in bundle.yaml. Juju makes use of machine IDs (check machine
section in bundle.yaml) to deploy service/s to a specific machine.


I hope it will help you a bit.

Thanks,
Junaid
