Looking for a simple card/cal/WebDAV server that runs in docker.
Have tried Davis, Radicale and Baikal but have either struggled to get them working or found them a bitch to maintain.
Doesn’t have to be a DAV type solution. Syncing/backing up contacts and calendars from an android phone is essential.
What troubles were you having with Baikal? I generally let mine just sit with a checked out tag from Git.
