Dockerized WordPress on a Raspberry Pi
This blog runs on a a Raspberry Pi since 9th April 2019 and surprisingly the Pi performs quiete well. WordPress on itself does not need too many ressources for my use case since i don’t have hundreds of visitors per day, leaving capcaity for other applications.
The current setup includes an out of the box docker-compose and a backup script which uploads files to the dropbox cloud storage. In this series i would like to give you a short introduction how my setup works and how you could set it up by yourself.
