Watchtower: Multiple running watchtower instances

[zamberjo]

Describe the bug

I am implementing watchtower and I would like to know how I can do my
case of use.

I have 2 types of containers: [image]:test and [image]:prod.

I would like the containers with tag test to be updated every 5 minutes. And the containers with tag prod through a schedule at 5am.

After studying it, I have decided to implement 2 watchtower:

• The first with name watchtower-test with args:
  --cleanup --tlsverify --interval 300 --label-enable
   - The second with name watchtower-prod with args:
  --cleanup --tlsverify --schedule "0 0 5 * * *"

And add to [image]:test containers the label:
com.centurylinklabs.watchtower.enable = true

But I just realized that there cannot be 2 active watchtower containers.
see code

Could this deletion be parameterized?
Is there another possible solution? What do you think?

To Reproduce

$ docker run -d --name watchtower-prod --label com.centurylinklabs.watchtower.enable=false -v /var/run/docker.sock:/var/run/docker.sock containrrr/watchtower:0.3.10
[some_id1]

$ docker run -d --name watchtower-test --label com.centurylinklabs.watchtower.enable=false -v /var/run/docker.sock:/var/run/docker.sock containrrr/watchtower:0.3.10
[some_id2]

$ docker ps --all --quiet --filter name='watchtower$'|wc -l
1

Hi there! 👋🏼 As you're new to this repo, we'd like to suggest that you read our code of conduct as well as our contribution guidelines. Thanks a bunch for opening your first issue! 🙏

I just reasoned around something very similar to what you're trying to achieve (although that user had a completely different goal) in #440. By adding a WATCHTOWER_SCOPE_UID env var, we could allow for multiple watchtower instances, as each would only kill other instances with the same scope uid.

Unfortunately, I don't really have time to implement this change at this point, so if you'd like to have a go at it, it would be awesome. I would of course aid as much as possible with reviews, cheers and cookies! 😅

I can try to implement the WATCHTOWER_SCOPE_UID approach

Hi @victorcmoura that would be great. The truth is that I have never programmed in GO, so it would be very helpful.
