Hi Michal,

Based on some comments from the community, I'd like to have your
attention on couple things here.

1. For now, "--db-nb-create-insecure-remote=yes" is set in
ovn-nb-db.json.j2, when deploy ovn-nb-db and ovn-sb-db.

That results a TCP method is set by ovn-ctl script to run
ovsdb-server.

It's recommended to not set TCP method in command line, instead,
create connection table for TCP method. That way, the inactivity
probe interval can be set in the connection table as well.

2. On chassis node (compute node or gateway node), ovsdb-server
opens TCP socket and ovn-controller connects to it. Since this
is local communication, it's recommended to use UNIX socket.
It also avoids inactivity probe.

How can I get update on Kolla container image updates?
For example, I am currently using ussuri, where OVN is 20.03.
I wonder if I can get upgraded ussuri image with OVN 20.06?
Or Kolla container upgrade is aligned with OpenStack release,
like I won't be able to get upgraded OVN until next OpenStack
release? If that's the case, I will just upgrade the container
by myself.


Thanks!

Tony
