I have several years of Linux experience and I know how to fix my own problems, and I have experience self-hosting using Docker and Docker Compose, but I really feel that I don’t know how to self-host and that I just copy and paste commands without understanding it, I would really like to learn how to self-host by myself but I don’t know how I can start or with what resources for newbies I can start with.
I am interested in self-hosting several services, but the one I am currently most interested in is changedetection.io, as there are multiple such services but they all require a membership fee, and I prefer to self-host on my own.
Proxmox is a hypervisor, which is an OS that is built to run Virtual Machines (proxmox also runs containers). It is open source and can be installed for free, just like any other linux distribution, the same way Windows is installed. There are tons of tutorials out there on how to use it.
From there, you could setup some popular containers, including nextcloud, or even install full OS’s in virtual machines to install software manually on them. It is a great first step, especially if you have limited access to hardware.
Holy shit, that sound super useful, thank you so much and everyone who has answered.
