Radicale

2026-04-15

Radicale is a lightweight CalDAV and CardDAV server for syncing calendars and contacts across devices.

This compose file deploys Radicale. Calendar and contact data is stored on an NFS volume, and the service is proxied through a Traefik reverse proxy with Cloudflare TLS certificates.
