Official Docker images #

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

• castopod/castopod: an all in one castopod image using nginx unit
• castopod/app: the app bundle with all of Castopod dependencies
• castopod/web-server: an Nginx configuration for Castopod

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! 🎙️🚀
