Official Docker images

Castopod pushes 3 Docker images to the Docker Hub during its automated build process:

Additionally, Castopod requires a MySQL-compatible database. A Redis database can be added as a cache handler.

Supported tags

  • develop [unstable], latest development branch build
  • beta [stable], latest beta version build
  • latest [stable], latest version build
  • 1.x.x [stable], specific version build (since 1.0.0)

Example usage

  1. Install docker and docker-compose

  2. Create a docker-compose.yml file with the following:

    version: "3.7"
    services:
    app:
    image: castopod/castopod:latest
    container_name: "castopod-app"
    volumes:
    - castopod-media:/var/www/castopod/public/media
    environment:
    MYSQL_DATABASE: castopod
    MYSQL_USER: castopod
    MYSQL_PASSWORD: changeme
    CP_BASEURL: "https://castopod.example.com"
    CP_ANALYTICS_SALT: changeme
    CP_CACHE_HANDLER: redis
    CP_REDIS_HOST: redis
    CP_REDIS_PASSWORD: changeme
    networks:
    - castopod-app
    - castopod-db
    ports:
    - 8000:8000
    restart: unless-stopped
    mariadb:
    image: mariadb:10.5
    container_name: "castopod-mariadb"
    networks:
    - castopod-db
    volumes:
    - castopod-db:/var/lib/mysql
    environment:
    MYSQL_ROOT_PASSWORD: changeme
    MYSQL_DATABASE: castopod
    MYSQL_USER: castopod
    MYSQL_PASSWORD: changeme
    restart: unless-stopped
    redis:
    image: redis:7.0-alpine
    container_name: "castopod-redis"
    command: --requirepass changeme
    volumes:
    - castopod-cache:/data
    networks:
    - castopod-app
    volumes:
    castopod-media:
    castopod-db:
    castopod-cache:
    networks:
    castopod-app:
    castopod-db:

    You have to adapt some variables to your needs (e.g. CP_BASEURL, MYSQL_ROOT_PASSWORD, MYSQL_PASSWORD and CP_ANALYTICS_SALT).

  3. Setup a reverse proxy for TLS (SSL/HTTPS)

    TLS is mandatory for ActivityPub to work. This job can easily be handled by a reverse proxy, for example with Caddy:

    #castopod
    castopod.example.com {
    reverse_proxy localhost:8000
    }
  4. Run docker-compose up -d, wait for it to initialize and head on to https://castopod.example.com/cp-install to finish setting up Castopod!

  5. You’re all set, start podcasting! 🎙️🚀
