awesome-selfhosted VS watchtower

I was in exactly your position a couple of months ago and have just got my first apps running this week!

Im a web developer so had a bit of experience with containers, cli and linux but only basic web related stuff.

Ill detail my journey and then let others tell you how wrong I am.

I bought a thinkcenter m715q for $200ish which was suggested as a good budget starting machine. There's lots of info about this on https://reddit.com/r/homelab , https://reddit.com/r/selfhosted and https://www.servethehome.com

I installed ubuntu and had a play around but then decided proxmox seemed like the way to go for what I wanted to so. So I watched a range of youtubers

> 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!
