Recommended containerized CardDAV/CalDAV solution?

The Stoned Hacker@lemmy.world to Selfhosted@lemmy.world – 20 points –

Hello! I am migrating some services from an old cloud instance to my homelab. The cloud instance was running NextCloud and as I don't really need the entirety of NextCloud, I'm moving to individual services. It's now time for me to move the most important thing from this NextCloud instance: my calendars and contacts.

I'm looking for a good containerized service to run this. I've taken a look at both Baikal and Davis, but both seem to have issues running rootless. As I have Kerberos throughout my network and am storing the persistent volumes on an NFS share, I prefer to run all my containers under dedicated service accounts. This also means that I would like the DAV server to have LDAP or IMAP authentication. I am also using podman quadlets rather than docker compose, but I can figure out the translation on my own. Worst case scenario here is I just run Davis and talk to the dev about the issues I have (which will probably be done anyways), but I'd like to get something up and running sooner rather than later. Any solutions would be greatly helpful. If there isn't a good containerized solution, I'm also willing to make an LXC or VM but I'd prefer to stick to containers. Thank you!

There's Radicale

+1 for radicale, I’ve been using it for several years now and have barely had to give it any attention at all.

I'm mainly concerned about auth with this one, it seems a little too barebones for my use case. Thanks for the suggestion though!

I second this if OP's not a fan of or doesn't need all of Nextcloud.

Can someone please ELI5 Radicale for me?

I've come across it before but just can't wrap my head around it. Thank you.

Simple Cal.And CardDAV server. Woks very well.

Well I almost have a solution for you, but it’s not ready yet. I have a WebDAV server called Nephele, but I haven’t finished writing the CardDAV and CalDAV extensions for it. I should be done with it in a few months. (My priorities are on my commercial project right now, then back to open source stuff in a couple months.)

Will keep an eye on this, looks interesting!

I am currently running baikal using podman, quadlets, rootless mode. What kind of issue did you have?

That said, although baikal does get the job done, I am actually considering migrating to nextcloud just because of caldav/carddav, since it seems to be the most complete implementation out there.

It is worth taking a look at the features you need before fully migrating. As far as I can tell baikal may have some issues for some people with invitations, sharing calendars and sending email.

I've seen people recommend radicale, which probably works well, but from what I read is the least adherent to caldav/carddav protocols.
