Docker Radicale

This is a small docker image for Radicale and easy deployment. Bcrypt authentication inclusive.

Installation

# .env
USER=foo
PASSWORD=secret

# docker-compose.yml
version: '3.8'

services:
  app:
    image: cupcakearmy/radicale:1
    restart: unless-stopped
    env_file: .env
    volumes:
      - ./data:/data
    ports:
      - 80:5232

The env file is not strictly required, but will generate a user with its bcrypt password if missing.

macOS Setup

Without SSL/TLS the native client seems to have problems, once SSL is enabled it works like a charm.

The same setup works for Calendar and on iOS.

Traefik

An example for traefik (v1) can found below.

version: '3.8'

networks:
  proxy:
    external: true

services:
  app:
    image: cupcakearmy/radicale:1
    restart: unless-stopped
    env_file: .env
    volumes:
      - ./data:/data
    networks:
      - proxy
    labels:
      - traefik.enable=true
      - traefik.http.routers.radicale.rule=Host(`radicale.example.org`)
      - traefik.http.routers.radicale.entrypoints=secure
      - traefik.http.routers.radicale.tls.certresolver=le

Customize

Config

You can overwrite the config by simply mounting it into /etc/radicale/config.

User Auth

The default script only creates a default user with the given USER and PASSWORD credentials. For multiple users you need to create the files manually. In the default config this is set to /data/users.

You can add users with htpasswd -bB -c /data/users user pass. And then mount that file to /data/users or whatever you have set in the Radicale config file filesystem_folder, more here.
