Any tips on how to check dockerhub images for new tags

Docker Hub
1

I have a lot of images running on my home platform, and as its my home platform I don’t have a team of people who are constantly monitoring patches etc for each component.

It would be great to have some kind of application that I can input dockerhub repositories in, and monitor if any new tags have been posted, and have this information collected in one place. For example:
gitlab: 1.2.34
python: 2.3.4
traefik: 6.4.3

I’m sure something like this already exists but I must be searching for the wrong keywords… otherwise I guess I have a fun project in front of me :smiley:

You might find what you are looking for in the Watchtower documentation: Without updating containers

Unfortunately Watchtower may still do a pull if the image has changed, so there’s a risk of accidental update.

This request seem to be so ubiquitous, and being able to query an action before doing it is so fundamental to good IT practice, why isn’t it part of the core product?

Is it safe to assume that you already raised a feature request in the docker github repo?
After all this is open source and it is a collective effort to make the dream come true.

My main intent was to highlight that Watchtower unfortunately doesn’t solve the problem fully, but I also added to one of the feature requests:

I had a further look at this since I really need something for my media centre installation, and it is just about possible using a bash script. No idea how reliable it will be in the long-run, hopefully it won’t be needed when it’s in the core, but for me it works for now.
