I would like to use docker compose to create a stack. one container for playing media from streaming services, and one container to take that media and record it. how would i go about that?

Creating a stack using Docker Compose for a media streaming application and a recording application involves several steps. Below, I'll outline a basic approach to get you started. ### Step 1: Identify Media Streaming and Recording Tools 1. **Media Streaming**: Assume you're using a tool like **Plex Media Server** or **Jellyfin** for media streaming. These applications can serve media to clients. 2. **Recording**: For recording media, you could use a tool like **Streamlink** or **ffmpeg**. Streamlink allows you to stream and record content from sites like Twitch, YouTube, etc. ### Step 2: Create a Docker Compose File Here's an example `docker-compose.yml` for a Plex server and Streamlink. ```yaml version: '3.7' services: plex: image: plexinc/pms-docker container_name: plex network_mode: "host" # Use host networking for Plex to access local networks environment: - PLEX_CLAIM=<your_plex_claim_token> # Get this from Plex website - PLEX_UID=1000 - PLEX_GID=1000 volumes: - ./plex/config:/config - ./plex/transcode:/transcode - ./media:/data # The folder where your media files will be stored streamlink: image: streamlink/streamlink container_name: streamlink depends_on: - plex volumes: - ./recordings:/recordings # Where you want to save recordings command: streamlink [stream_url] best -o /recordings/recorded_stream.ts # Replace [stream_url] with the actual stream URL ``` ### Step 3: Create Directory Structure ```bash mkdir -p plex/config plex/transcode media recordings ``` ### Step 4: Generate Plex Claim Token 1. Sign in to your Plex account. 2. Go to the [Plex Claim Token page](https://www.plex.tv/claim/). 3. Copy your claim token and replace the `<your_plex_claim_token>` in the `docker-compose.yml`. ### Step 5: Run the Docker Compose Stack Make sure you are in the directory where your `docker-compose.yml` file is located. Run the following command to start the stack: ```bash docker-compose up -d ``` ### Step 6: Access the Applications - **Plex**: Open a browser and go to `http://localhost:32400/web` to access your Plex server. - **Streamlink**: You need to configure or run the Streamlink command that you specified in the `docker-compose.yml`. You may want to use a specific URL for [stream_url]. ### Additional Notes 1. **Dependencies**: Your recording container (`streamlink`) is set to depend on `plex`. Ensure that your recording logic works after starting Plex. 2. **Recording Triggers**: If you need to automate your recording logic or schedule recordings, consider creating a separate service that calls the Streamlink command or scheduling it with a cron job. 3. **Security and Networking**: Depending on your use case, you might want to adjust network configurations and security settings for your setup. 4. **Testing**: Ensure to test all components after starting them. Use logs (`docker-compose logs`) to troubleshoot any issues that may arise. 5. **Overwrite Streamlink command**: To make the `streamlink` service record only when needed, you might need to manually trigger the command or set up a mechanism (like a REST API or a task scheduler) to run the command based on specific conditions. This setup is a basic start. Depending on your specific requirements and tools you choose, adjustments might be necessary.
