Dear release team,
Since Buster was frozen, I worked quite a long time on Octavia, and was
able to make the octavia-agent work properly, as well as building an
Octavia base image using Debian only stuff [1]. It works super well
using the next version of OpenStack, ie: Stein, while Buster has Rocky.
Though I'd like to be able to provide a working Amphorae image using
only stuff from Buster, if possible. This is what this update is about.
The update contains:
- Fix for the vrrp script template.
- Fix for detecting the OS from within Octavia itself.
- Fix for CVE-2019-17134, where the Amphora didn't enforce cert checking.
- Fix for the octavia-agent package init / systemd scripts.
Debdiff is attached. Please allow me to update the Octavia package in
Buster accordingly. Next up, I hope to be able to provide a Debian image
for Octavia through the official cdimage.debian.org repo. I'll do that
through Testing first.
Cheers,
Thomas Goirand (zigo)
[1] If you don't know what Octavia is, it is haproxy as a service, with
a base virtual machine image containing Haproxy and the Octavia Agent.
This image is called "Amphorae", and can be used to provide load balancer
as a service. This is quite nice technology!
