Open Stack

Hi Tony,

This isn't a bad place to ask questions if you like email discussion.
Just make sure to prefix your email subject lines with [kolla].
We are also on IRC (#openstack-kolla on the OFTC network).

I will reply to your questions inline.

I searched online and came across other ansible users that state their playbooks were hanging and were able to resolve by clearing cache. I've tried clearing out ~/.ansible/* and /tmp/* on the control host. Also tried doing the same on the all-in-one host without success. This issue came about after doing a full destroy of the environment and then redeploying, making a minor config change and then redeploying.

We would need more information to help you.

What does your configuration look like, in particular the network and
this bridge you mention?
What command did you run and at which step does Kayobe hang?
Are you able to SSH to your hosts successfully?

Kayobe doesn't set a password for the "stack" user, you should use SSH
keys to connect.

I've attached the logs that appear at the point the network dies: https://pasteboard.co/K65qwzR.png

Again it would be good to see your network configuration. Do you have
a single interface without any VLAN tagging that you are trying to use
with Kayobe?
