Background: I have a Raspberry Pi 4 running OSPi with a regular SD card. Since I had an SD card failure on another (indoor) Raspberry PI, I thought it would be a good idea to replace the old SD with a better (more outdoor suitable) one on the OSPi better now then before it breaks too. Also I need to upgrade OSPi to the latest version. And also I want to install Home Assistant – and Home Assistant is installed as Docker image by recommended default (https://www.home-assistant.io/installation/raspberrypi#install-home-assistant-container). Also, there is Apache running as an https service. Anyway, so I thought for the sake of an easier migration and upgrades in the future to also run OpenSprinkler (and all other services) using Docker.
