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.
Would have said baikal if you haven’t alteady mentioned it. Can’t confirm that it’s a bitch to maintain, runs in my webjail for more than a year now. (Before I used nextcloud which IS a bitch in all matters…) The only hiccup was self induced, forgot to install it after php upgrade (FreeBSD, pkg is named php83-baikal for example).
Specifically for webdav (Joplin sync) I use dave, though unmaintained no issues so far (internal network only, not web facing).
