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 @[email protected] 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 @[email protected], which discusses the Kubernetes tool Renovate.
I don’t believe it has any git integration and just updates the deployed manifests directly.
As far as revision history I’m not certain.
If you are looking for git integration you might want to look into Argo.
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!
