Open Stack

Hi all,

I have deployed OpenStack on my system (all with Ubuntu 20.04 Desktop
versions) using kolla-ansible deployment. I am able to launch containers
and open the terminal (console of containers) in the web-browser from the
horizon dashboard. However, when I installed an OpenStack on my system
using *Ubuntu 20.04 Server* version using kolla-ansible deployment, all
containers were running, but I was not able to access the terminal in the
web-browser on the horizon dashboard for the running container. I am
getting an error message "*Firefox can't establish a connection to the
server at wss://...*" All my OpenStack is deployed using the Python virtual
environment. I have been following the exact steps in deploying OpenStack
from "https://docs.openstack.org/kolla-ansible/yoga/user/quickstart.html."
My current OpenStack version is yoga.

Apart from that, I would like to ask if there is any specific path I can
make modifications on my OpenStack. Every time when I deployed a fresh
OpenStack on my system and tried to make some modifications, the path might
not take any effect on the horizon dashboard. Sometimes, modifying the
library in
/var/lib/kolla/venv/lib/python3.8/site-packages/openstack_dashboard and
restarting horizon updates the modification. Sometimes, it might be in
/horizon-source/.../openstack_dashboard/.

Thank you,
Vincent
