If you have your own VPS anyway, there is the Matrix Ansible Playbook which makes the setup with docker containers very easy. But I also get the sentiment that you don’t want to tinker around all the time and just want stuff to work.

Kudos to you for using Matrix in the first place, I hope you can bring a lot of your friends and family to switch over to it. So far this has been the biggest hurdle on my journey 😅
