Must Have Docker Containers on your Home Server

Januar 10, 2023 - Lesezeit: 2 Minuten

Your home server could be huge server racks, a NAS such as Synology or a Mini PC such as a Raspberry Pi. Regardless of the hardware choice, as long as you can install and run container management systems such as Portainer CE, Ranger, Yacht, etc. the following containers might prove as helpful and improve your digital & real life tremendously.

But first thing first, what you might need as a minimal set-up could be a Raspberry Pi. I would say a Raspberry Pi 4b with 4GB of RAM should be sufficient, but 8GB is definitely the preferred option. The next thing you need is to have docker installed. Once that's ready, you can choose between Portainer CE, Ranger, Yacht or any other container dashboards you find suitable for you out there. For my personal taste, OpenShift and Ranger are overkills while Yacht is beautiful and has huge potential, but too unstable. Hence up to this point in time, I stick with Portainer CE, which does the job quite well and supports more hosts than Yacht. 

Heimdall

The first tool I would recommend is Heimdall. It is an application dashboard, very simple to set up and beautiful at the same time. Applications in your home network will be accessible with a few clicks and look much more attractive. Some apps are even better integrated and display elegant interactive details on the thumbnail.

One of the major advantages of Heimdall is the easy set-up and sleek design. In case you are looking for even more performance, you can go for Fenrus. If you want more configuration options and are familiar with Linux environment, Organizr might be something interesting. Homer and Dashy are also on the show if your heart longs for other alternatives.
