Hey there, creator of Vikunja here.
It's really awesome to see people using Vikunja
I'm not very familiar with cloudron so this is probably a noob question, but is there a special reason you're creating seperate docker images instead of using the official ones? This feels a bit like doubled effort.
Maybe we could even officially support cloudron with releases automatically published through our ci.
Also, please don't hesitate to ping me if you have any questions about Vikunja, either here or in Vikunja's Forum or through other ways.
