Radicale

There is no official docker image. This was the most up to date project.

Step 1: Create Configuration Directory

Create a directory to store your Radicale configuration files:

mkdir -p /srv/Files/Radicale/config

Step 2: Create Configuration File

Create a file named config inside the config directory:

nano /srv/Files/Radicale/config/config

Paste the following configuration into the config file:

# -*- mode: conf -*-
# vim:ft=cfg

# Config file for Radicale - A simple calendar server
#
# Place it into /etc/radicale/config (global)
# or ~/.config/radicale/config (user)
#
# The current values are the default ones

# Use subfolder 'collection-cache' for 'sync-token' cache file structure instead of inside collection folder
# Note: use only on single-instance setup, will break consistency with client in multi-instance setup
#use_cache_subfolder_for_synctoken = False

# Use last modifiction time (nanoseconds) and size (bytes) for 'item' cache instead of SHA256 (improves speed)
# Note: check used filesystem mtime precision before enabling
# Note: conversion is done on access, bulk conversion can be done offline using storage verification option: radicale --verify-storage
#use_mtime_and_size_for_item_cache = False

# Use configured umask for folder creation (not applicable for OS Windows)

# Command that is run after changes to storage, default is emtpy
#  Supported placeholders:

#max_freebusy_occurrence = 10000

Step 3: Create Users File

Create a file named users inside the config directory:

nano /srv/Files/Radicale/config/users

Each line in the users file should contain a username and a bcrypt-hashed password, separated by a colon (:). Use a tool like Browserling's BCrypt Generator to generate the hashed passwords. The file should look like this:

john:$2a$10$l1Se4qIaRlfOnaC1pGt32uNe/Dr61r4JrZQCNnY.kTx2KgJ70GPSm
sarah:$2a$10$lKEHYHjrZ.QHpWQeB/feWe/0m4ZtckLI.cYkVOITW8/0xoLCp1/Wy

Step 4: Create and Run Docker Container

Create a docker-compose.yml file with the following content to define your Docker service:

services:
  docker-radicale:
    container_name: radicale
    ports:
      - 104.152.49.17:5232:5232
    init: true
    read_only: true
    security_opt:
      - no-new-privileges:true
    cap_drop:
      - ALL
    cap_add:
      - CHOWN
      - SETUID
      - SETGID
      - KILL
    deploy:
      resources:
        limits:
          pids: 50
          memory: 256M
    healthcheck:
      test: curl --fail http://localhost:5232 || exit 1
      interval: 30s
      retries: "3"
    volumes:
      - /srv/Files/Radicale/data:/data
      - /srv/Files/Radicale/config:/config:ro
    image: tomsquest/docker-radicale
networks: {}

Run the following command to start the Docker container:

docker-compose up -d

This will start the Radicale server with the specified configuration.
