Does Juju really need two nodes?

Question

Hi I am trying to deploy openstack with Juju and MAAS. But the Juju bootstap is still with the Status Connecting to Environment:

marcel@ubuntu20:~$ juju -v status

I waited now two days and nothing happened:

But I have only one node because I wanted to check if it is realy working before I continue and install more nodes. But I read https://wiki.ubuntu.com/ServerTeam/MAAS/Juju Have at least two nodes added to your MAAS. That I need at least two nodes. Do I really need two nodes? that the Bootstap is working ? I am not in the lab so I can't install one more node so easy. But if it will work I will than I will go there...

And is there anyway to do the Bootstrap manually that I can do it instand. I am running out of time and I really need to deploy openstack I can't wait days to do the bootstap.

Answer 1

JuJu does need 2 nodes to do anything useful. You should be able to bootstrap your juju maas environment with 1 node, but that would be it.

It seems to me that the juju bootstrap node has had some issue in your case. I do not think installing an additional node would fix your problem.

Could you collect (and post somewhere) the contents of: /var/log/cloud-init-output.log /var/log/cloud-init.log /var/log/juju

I suspect if you look in /var/log/cloud-init-output.log on the bootstrap node you might see something that points to your problem.
