I deploy and update my service similiar to this fantastic guide: https://nickcunningh.am/blog/how-to-automate-version-updates-for-your-self-hosted-docker-containers-with-gitea-renovate-and-komodo
Basically I run Komodo, which pulls a git repo. Renovate opens a PR (and most of the time the changelog is included, so I can quickly check what happened) for new versions. Once merged a webhook fires to tell Komodo to pull the new version.
I really recommend this approach now. Once setup it is very automatic, but not to the point of YOLO-automation like Watchtower and :latest 😅




Not that I am aware of. Komodo should be compatible with podman as well.
