Self-Hosted Main

My Pi runs ubuntu 22.04 and docker with portainer, watchtower, adguardhome and tailscale

I use Docker on my Pi for one simple reason: management. While it's true that some services are set and forget, there will be times when you will need to check on a particular service's health, and Docker makes it a little easier by having each service on it's own environment. You can restart every service individually with ease, and even nuke something if needed without wrecking the whole system.

I use Portainer, and everything on Docker inside it.

If you're already familiar with it and can maybe even reuse some compose files, it's definitely worth it. Even on a Pi.

It is up to you. Using Docker makes it easier for administration and evolution, but bare metal is sufficient if you are comfortable with it (which every self-hoster should be).

i recently got my first raspberry pi and have a drupal website which consists of three docker container. not sure how it’ll handle high traffic but so far it works like a charme.

Yes. Using docker is not like running your services inside VMs. It's a pretty lightweight way of structuring your services, with the host kernel shared by all instances.

I run everything in Docker on my RPi 4 and it works very well.

I just installed paperless-ngx on my Pi with Docker. I read the instructions on doing it bare metal and thought "Nope!" So yeah, it can save you some work.
