openHAB with InfluxDB, and Grafana, on Docker!

Wow, what a long title. But this is the setup I want. Tutorials on the internet are either hard (impossible) to follow or outdated. Until today, I use JDBC persistence and MariaDB as database (because I already have it for my Nextcloud). For the data generated through my smart home, this is not the best choice. Soon I’ll also have photovoltaics on my roof where I want to do some visualization. So why not use the chance to move on and do a clean setup with all the things named in the title?
