# Official Docker images
|
|
|
|
Castopod pushes 2 Docker images to the Docker Hub during its automated build
|
|
process:
|
|
|
|
- [**`castopod/app`**](https://hub.docker.com/r/castopod/app): the app bundle
|
|
with all of Castopod dependencies
|
|
- [**`castopod/web-server`**](https://hub.docker.com/r/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
|
|
- `1.0.0-beta.x` [stable], specific beta version build (since `1.0.0-beta.22`)
|
|
|
|
## Example usage
|
|
|
|
1. Install [docker](https://docs.docker.com/get-docker/) and
|
|
[docker-compose](https://docs.docker.com/compose/install/)
|
|
2. Create a `docker-compose.yml` file with the following:
|
|
|
|
```yml
|
|
version: "3.7"
|
|
|
|
services:
|
|
app:
|
|
image: castopod/app:beta
|
|
container_name: "castopod-app"
|
|
volumes:
|
|
- castopod-media:/opt/castopod/public/media
|
|
environment:
|
|
MYSQL_DATABASE: castopod
|
|
MYSQL_USER: castopod
|
|
MYSQL_PASSWORD: changeme
|
|
CP_BASEURL: "http://castopod.example.com"
|
|
CP_ANALYTICS_SALT: changeme
|
|
CP_CACHE_HANDLER: redis
|
|
CP_REDIS_HOST: redis
|
|
networks:
|
|
- castopod-app
|
|
- castopod-db
|
|
restart: unless-stopped
|
|
|
|
web-server:
|
|
image: castopod/web-server:beta
|
|
container_name: "castopod-web-server"
|
|
volumes:
|
|
- castopod-media:/var/www/html/media
|
|
networks:
|
|
- castopod-app
|
|
ports:
|
|
- 8080:80
|
|
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"
|
|
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](https://caddyserver.com/):
|
|
|
|
```
|
|
#castopod
|
|
castopod.example.com {
|
|
reverse_proxy localhost:8080
|
|
}
|
|
```
|
|
|
|
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! 🎙️🚀
