[Question] How to use minor version but monitor for patch

[RichyHBM]

Hello, I am looking to answer a question regarding docker image versions.

I want to use minor versions for my docker images where available, i.e. 1.23, but have WUD notify me when a new patch version is available. This works ok using patch compatible regex, however if I update that container to the latest patch, WUD still lists it as an available update, even though they are at the latest.

Is there any setting that can achieve the desired outcome? Would I need to watch digests as I currently disable this where possible to minimize on dockerhub API calls

Hello,

I'm not sure to exactly understand your situation; can you provide a small example of your configuration, please?

If I take the example of nginx, they provide the same image as 1, 1.27 and 1.27.0.

I basically would say:

• if you want to keep your image up to date as soon as a new patch is available, use the 1.27.0 tag and set wud the include regex \d\.\d\.\d
• if you want to keep your image up to date as soon as a new minor is available, use the 1.27 tag and set wud the include regex \d\.\d
• if you want to keep your image up to date as soon as a new major is available, use the 1 tag and set wud the include regex \d

But maybe I have misunderstood your issue...

@fmartinou I think I get what @RichyHBM meant, as apparently I'm in a similar situation (use major and watch for minor updates). Let me explain:

• Let's say I'm running a Postgres container; in my compose.yml I specify the image as postgres:16.
• I want WUD to notify me when a new minor version like 16.3 is available (which means 16 has also been updated on Docker Hub and I can just run docker compose pull to get it without having to change compose.yml), so I set wud.tag.include=^16\.\d+$$.
• Now, even if my local postgres:16 image is up-to-date and actually has the same digest as postgres:16.3's, WUD still shows that a minor update is available.
• Thinking that if WUD sees that they have the same digest, it'll know that there's in fact no update, I set wud.watch.digest=true and recreate the container.
• However, WUD still says that there's an update, even though now I can see on WUD's container page that the current image's digest and the "new" one's digest are the same:

If WUD would compare digests with wud.watch.digest=true even when tags are different (16 vs. 16.3 in this example) to decide whether there's an update, it would be perfect.

I'm aware that I can set wud.tag.include=^16$$ and wud.watch.digest=true to get "correct" notifications, but that way WUD won't be able to show what minor version the update is—is it 16.3 or 16.4?

I think this is kinda finicky and it's totally fine if you decide to keep the current behavior. Just wanted to chime in and try to make it clear. Thanks for this useful piece of software!
