Hello Greg,

When you restart the Horizon container, it keeps running from the existing,
modified container image. The container image is only recreated from the
pulled image by deploy or reconfigure actions in Kolla. So, if you don't
want to use Kolla to build a new image (which I would recommend as you can
keep your modifications in version control!), you can `docker commit` your
changes into a new image, which you could push to your local registry for
redeploying later.

Best wishes,
Pierre
