Latest Watchtower fork?

cross-posted from: https://lemmy.world/post/26728988

Hi - I'm rebuilding my homelab and want to give docker compose another try. It looks like Watchtower is years out of date now. I see two forks that look more promising per https://techgaun.github.io/active-forks/index.html#https://github.com/containrrr/watchtower

These two: https://github.com/beatkind/watchtower https://github.com/nicholas-fedor/watchtower

The former seems to have more activity. What are you all using?

Those of you self hosters who use watchtower, what's your use case?

I only let me notify about updates. I don't want autoupdates, because some projects may have breaking changes (looking at you Immich 😁)

I get a message from watchtower over Gotify and then I can read the changelog

I've been thinking about this. Can you do that with watchtower? Don't need diem or anything?

It is very easy. Here is my compose:

services:
  watchtower:
    image: containrrr/watchtower
    container_name: watchtower
    restart: always
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /etc/localtime:/etc/localtime:ro
    command: --interval 10800
    logging:
      driver: local
    environment:
          WATCHTOWER_NOTIFICATION_URL: gotify://
          WATCHTOWER_NOTIFICATIONS_HOSTNAME: Fancy name
          WATCHTOWER_MONITOR_ONLY: true
          WATCHTOWER_WARN_ON_HEAD_FAILURE: never

Every 3 hours it will check for updates, send a message via Gotify and pull the new images. It will not restart the containers with the new images.

Is it possible to have it auto update say one container and notify the rest?

Yes. There is a label you would need to apply to all of your containers to specify whether or not to update: com.centurylinklabs.watchtower.monitor-only=true

Honestly I think this might be a better way than what I’m using now. I’ve subbed to dockerrelease.io (edit: docker-notify.com) and releasealert.dev … get spammed all day everyday because the devs keep pushing all sorts of updates to old branches… or because those sites aren’t configured well.

Automatic updates. Works like a dream. Depending on what you are running it can obviously cause issues, either server side breaking or server,client communication issues

Auto update. Works like a charm, except PostgreSQL. For me it's good enough and even though works with containers, where they don't recommend it. I do have backups and for my private time, I don't get paid, so it should be as maintenance as possible from my side.

I do check from time to time if something is broken and I noticed a container where they removed a version tag, I was using. The "biggest" thing that was broken, was my gitea server where they changed the config for the default Theme.

Also that's why I hate PostgreSQL. It requires manual labor for updating. Had a recipe Docker and they cut support for previous major version quickly. Not good. That stuff could break, ist an option with every update. This is why backups exist. As a single user, it's not a problem. For a big system, I wouldn't do auto updates, so I can check if everything works.

I use it to auto update nginx and haproxy containers, since they adhere very well to semver there is very little risk of breakage if you use the correct tag and not just :latest. I haven't had a single issue in many years, and it's nice to know that I'll get critical security updates within 24h of images being pushed.

Yeah but what are you updating that is so non-critical you can trust watchtower to update it unattended, without reading release notes?

Years out of date

What problems does it have? Never ran into an issue for my usecase.

I don't know. Last time I used it was maintained. Seems like a security vulnerability running something this critical out of date, no?

Just because there is no update does not mean there are security vulnerabilities to worry about, or do you have a specific one that is not fixed?

The attack vector seems very narrow to me. It checks the container registry downloads the containers and runs some docker commands.

It has no interface, so in order to attack it you either have to compromise the container registry (but then it would be easier to compromise the containers you download) the secure connection used to download the containers (https is quite stable) or something on the server side.

Also the project does not really look that abundant to me.

EDIT: So i have not checked this, but watchtower is probably using docker for most steps anyway? So basically the only thing that could be attacked is via the notifications watchtower is sending?
