I’m trying to find a video that demonstrated automated container image updates for Kubernetes, similar to Watchtower for Docker. I believe the video was by @geerlingguy@mastodon.social but I can’t seem to find it. The closest functionality that I can find to what I recall from the video is k8s-digester. Some key features that were discussed include:

  • Automatically update tagged version number (eg - Image:v1.1.0 -> Image:v1.2.0)
  • Automatically update image based on tagged image’s digest for tags like “latest” or “stable”
  • Track container updates through modified configuration files
    • Ability to manage deploying updates through Git workflows to prevent unwanted updates
  • Minimal (if any) downtime
  • This may not have been in the video, but I believe it also discussed managing backups and rollback functionality as part of the upgrade process

While this tool may be used in a CI/CD pipeline, its not limited exclusively to Git repositories as it could be used to monitor container registries from various people or organizations. The tool/process may have also incorporated Ansible.

If you don’t know which video I’m referring to, do you have any suggestions on how to achieve this functionality?

EDIT: For anyone stumbling on this thread, the video was Meet Renovate - Your Update Automation Bot for Kubernetes and More! by @technotim@mastodon.social, which discusses the Kubernetes tool Renovate.

    I found what I was looking for - Renovate. I was wrong about it making branches (just makes pull requests). Looking into it a little further though, it seems people use Renovate (to automate updates) in conjunction with something like Argo (to automate deployments).

    I think Keel does both of those tasks? I still need to research the similarities/differences of Keel and Renovate a bit further. Thanks again for the recommendation!
