Hello, I would like to ask if the procedure I am using for update my kolla wallaby is correct. Every week new images are released so I execute the following steps:
1. Pull new images on my local registry
2 pull new images from my local registry to controllers and compute nodes
3 kolla-ansible deploy
Are the above steps the correct way or I missed something? Must I clean something before deploying ? Thanks

This approach is correct. Step 2 will ensure `kolla-ansible deploy` knows that new images are available. You can verify it yourself: after executing step 2, run `docker ps` on your nodes and you should see containers running from images identified only by an ID. This is because the tag (for example wallaby) references the new image. However, as Sean said, changing the tag each time you redeploy will allow you to revert to previous container images if anything went bad. Additionally, it would allow you to skip step 2, since the deploy command will automatically pull images from the local registry, as they will be absent from the nodes.
