Indeed, I wouldn't advise pulling upstream container images directly to your compute hosts. You should mirror the container images into a local registry. This will ensure you get a homogeneous deployment.

Just a little operator anecdote,  we build all our our images using the kolla image builder instead of pulling from public repos.  It gives us a better option for versioning our containers so we get homogeneous deployments.  When we used the upstream repos we couldn't guarantee that our images would be the same between say the original deployment and the deployment of some new computes a month or so later.

It is generally recommended to use the stable branch, for example stable/xena in your case, to get the most recent images.
You can build your own or pull them from quay.io.

Hello.

I have a question.

I use kolla-ansible 13.0.0 and kolla 13.0.0 images then I upgrade kolla-ansible to 13.8.0. I will use kolla 13.8.0 to build new images?

Thank you. Regards
