In OMV4 I install additional webpages/services via the way explained by ryecoaaron in (for instance) this topic. I have Spotweb installed via this tutorial.
The tutorial requires the MySQL and Nginx plugins, both will not be present as plugin in OMV5, Docker has to be used instead (source). I'm experimenting/learning in OMV4 so I can upgrade to OMV5 when it's stable.
I've searched the forum (specifically these tutorials and the video tutorials Techno Dad Life has made).
How can the tutorial from ryecoaaron be used in Docker?
For info: I'm running this on an ARM system.
