hbm VS watchtower

Beware that harbormaster is also the name of a program for adding RBAC to docker: https://github.com/kassisol/hbm

It's kind of abandonware because it was the developer's PhD project and he graduated, but it is rather unfortunately widely used in one of the largest GEOINT programs in the US government right now because it was the only thing that offered this capability 5 years ago. Raytheon developers have been begging to fork it for a long time so they can update and make bug fixes, but Raytheon legal won't let them fork a GPL-licensed project.

> 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.

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.

You can use Watchtower (https://containrrr.dev/watchtower/) that solves problem of manual pulling on VPS.

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.

Have you ever deployed a Docker app on a server, but everytime you push a new version of your image to a Docker registry you need to manually restart your app? If you want to automate this restarting, this blog post is for you! I am now going to show you how you can do this with literally 1 simple command using Watchtower!
