Exclude containers without using labels?

[Skylark13]

Hello,

I wonder if there is another way to exclude checking for updates for specific containers.

From what I understand, if I don't want WUD to check for updates for specific containers, I have two options:

• either set WUD_WATCHER_{watcher_name}_WATCHBYDEFAULT to true (the default) and then set wud.watch to false on containers I want to ignore, or
• set WUD_WATCHER_{watcher_name}_WATCHBYDEFAULT to false and then set wud.watch to true on all containers I want to check for updates.

In my use case, the first option is not possible, and the second is possible but not ideal, because whenever I add a new container I would need to remember to add that label to it (not the end of the world, but ideally I'd like to not need to remember this in 6 months, a year or more when I go to try a new app and wonder why WUD is never showing updates for it).

My use case is that I am running TrueNAS with a few "apps" (which are docker containers, but which are managed by the TrueNAS OS itself), and in addition I am running some of my own containers (using Portainer). I cannot change the docker-compose for those containers so that's why the first option is not possible (well I can, but only by converting them to a "custom app" which I would prefer not to do, if I do that I might as well stop using TrueNAS apps and just manage all my own containers, but using apps has a few nice ease-of-use features).

I want WUD to only tell me about updates for the non-TrueNAS containers, because I cannot update the ones managed by TrueNAS myself anyways, and TrueNAS publishes updates when they feel like it and I can see and apply them in the TrueNAS web UI, so it's not useful to see them in WUD too.

So far I have just been ignoring the TrueNAS container updates, but it would be nice to be able to have WUD ignore the TrueNAS apps and see "0 updates available" 😄

What I would like is a way for WUD to ignore certain containers from the server's own settings. It could be a substring/regex match. For example if there was a way to do something like:

    ...
    environment:
        - WUD_WATCHER_{watcher_name}_EXCLUDECONTAINERS=^ix-

This would work great for me, because the names of all containers managed by the TrueNAS apps system start with the string "ix-".

Let me know if I missed something that already exists in the docs. If this would not be generally useful in your opinion, feel free to let me know, and I'll do it the other way even if it's not what I'd prefer.

Thanks in advance.
