Docker Swarm: automatically update service when new image is released
Since watchtower doesn't support Docker Swarm I've come across shepherd but the author has stated that he wont be maintaining the project anymore which makes me reluctant to use it.

Reminder to do some docker maintenance
Shepherd for those of that run docker swarm.
- Watchtower with Docker Swarm?

Do you have auto update for your containers ? (with watchtower for example)
Not at production (there are strict versioned images), but personally I use Shepherd in my distributed Docker Swarm (many hosts in different locations, even different architectures). I wonder why people say about some terrible issues. I must be very lucky: for over a year usage I've had only single one problem when service wasn't properly restarted (I remember it was Traefik). The only services excluded from auto-update are PostgreSQL and MongoDB (MariaDB works fine with auto updates).

Docker image update notifier
Because all my Docker services are running in Docker Swarm I use similar project shepherd (available also at dockerhub). Not many features, but extremely easy to set up and it does its job (check, download and restart any service when new image is available, so I don't need to care about program updating at all).

> if you're using the docker image, upgrades are a breeze. Just bump the tag on the image, redeploy, and you're done.
Or you could just run Watchtower beside it and it will automatically update your docker containers. https://github.com/containrrr/watchtower If you are OK with automated updates.

The Curse of Docker
So i primarily use containers on my local machine walled off from the internet, so it's not a big concern for me. Watchtower [1] is popular among home server users too which automatically updates containers to the latest image.
For production uses I think companies generally build their own containers. They would have a common base linux container and build the other containers based off that with a typical CI/CD pipeline. So if glibc is patched, it's probably patched in the base container and the others are then rebuilt. You don't have to patch each container individually, just the base. Production also minimizes the scope of containers with nothing installed except what's necessary so they have few dependencies.

Running watchtower weekly or whenever new image is available
I checked https://containrrr.dev/watchtower/ and Arguments, but I don't understand where to attach that using portainer.

Again, there are options to automate some of the burden here by using tools such as Watchtower.
