Yes, I totally agree. Docker "latest" tag is a bad pattern. We're also not using "latest" in other projects where we choose tags. I was pulling the (default) latest tag because I couldn't see any other tag on hub.docker .com. Based on this and above feedback my conclusion is that the public registry is not reliable enough and we should build our own images and run our own registry. Thanks everyone.

It is not really that. It seems Docker Hub has its worse days and I found myself confused on our or others images from time to time (that they presumably lack expected tags). you could just tag master with latest too
the issue with latest is people have different expectaions. i expect it to be the tip of master e.g. the latest version of the commited code where as other might expect ti to track the latest stable release e.g. victoria
kolla chose not to provide a latest tag since that terminology is not used in the kolla project but that could alway be changed if it was useful or provided better ux you just need to decided what latest means in the context of kolla

The moment that you couldn't find any tags in kolla images might be the generator is pushing. Kolla will generate then push images to Docker Hub. And because this mechanism will working in multiple releases at the same time, it's normal that not showing up image tags in Docker Tag web site when in progress.

Hi Eddie,
That makes sense and works, indeed:
docker pull kolla/centos-source-nova-api:victoria
I was seeing no tags here the other day:
https://hub.docker.com/r/kolla/centos-source-nova-api/tags?page=1&ordering=last_updated
I can see the tags now. It probably just took too long for the tags
to load.
Thanks

Hi Adrian,
IME, there's no image tag for latest. Most of kolla images are
using Openstack release name as tag.
If you want to pull image with specific Openstack release, you should pull them with release name tag.
E.g docker pull kolla/centos.source-nova-api:victoria

Hi,
None of the Kolla images on the Docker public registry are
tagged.
E.g. https://hub.docker.com/r/kolla/centos-source-nova-api
Images don't even have the "latest" tag, though they were
updated 15 hours ago.
And therefore they can't be pulled:
$ docker pull kolla/centos-source-nova-api Using default tag: latest Error response from daemon: manifest for
kolla/centos-source-nova-api:latest not found: manifest unknown: manifest unknown
Is there another public registry where ready-built Kolla images
are available?
Thanks
