🏔️ Alpine - Radicale

CalDAV and CardDAV server with LDAP/AD authentication

SYNOPSIS

What can I do with this? This image will run Radicale with an additional LDAP/AD authentication plugin. You can use this image to store or share calendars or address books, or both. Create fine grained ACL via the rights config, where you can give certain people read-only access to objects in your shared address books or calendars.

VOLUMES

• /radicale/etc - Directory of default.conf
• /radicale/var - Directory of all calendars, adressbooks and all other objects
• /radicale/ssl - Directory of ssl certificates for TLS
