So, right out the gate, I realize Watchtower has been abandoned. I get that. Still, it’s a great app. 95% of the time, it works every time.
The issue I have is as follows:

It doesn’t do this everytime, and it’s not one particular container. It seems random. For the example of SearxNG, I have not specified a MAC address.

In fact, I’ve never specified a specific MAC for any of my containers, and just let Docker do what it do. I’m just wondering if anyone has run up on this issue, and what did you do to remediate it, besides use another updater app? I like Watchtower, but only 95% of the time. LOL
It’s not a huge issue spinning the container back up. Takes less than 30 sec. However, that’s not how it’s supposed to work, so I seek input.
ETA: Just adding this for anyone who is testing the Watchtower fork or are thinking about it. Day 2, and everything is running just fine. I have not had any of the issues that I had with OG Watchtower:

Tooting my own horn here and I know it’s not a 1-1 replacement, but as others mentioned some great alternatives (diun, cup, wud) I’d like to suggest dockcheck.
I’m a big fan of options my dude. Checked it out. Looks very interesting. I do like these video caps you guys include in your instructions. Being a very visual person, it helps out a lot. It is bookmarked in my projects folder.
Thank you! Yeah I’m the same - if the first thing I see on a project page is some picture or video or output of what it’s about I’m much more intrigued to read on.
Did not know it was abandoned, will look thru all this tonight.
Perhaps I should clarify. The project ‘appears’ to have been abandoned or is no longer being maintained. I don’t want to go starting shit that doesn’t need starting.
Here is a fork of watchtower that is meant to keep things up to date that might work for you. I haven’t tried it yet but am setting it up now.
Thanks, I’ll give it a go

So far so good with my change. :)
Day 1. It seems to work:

Personally having great results with Diun. Same idea (check for newer container image) and works 100% for me.
Don’t know if it can automatically load and restart containers, rather do that personally.
What is the point of this type of service if you’re not getting it to automatically load and restart containers?
Does it notify you of newer container images or something?
I never bothered to set up watchtower because I didn’t want it to just apply updates before I could read the changelog. But maybe I was confused about its purpose.
Exactly this. It checks periodically if a newer image for the tag of the container is available (e.g. vaultwarden:latest) and tells you about it. You can setup mail, sms, Teams, you name it.
So then you know a new version is available, can check the changelog and decide if the update is worth it.
Ah sweet! Good to know, thanks!
It’s on the list.
