Simple RTMP Restreamer automatically saves all stream and target configuration to a file named simple-rtmp-restreamer.data.json in the application’s working directory. Every time you create or delete a stream, or add or remove a restream target, the file is written immediately. Without a persistent volume mount, this file lives inside the container and is lost when the container is removed or recreated.

​
Mount a persistent volume

To keep your configuration across container restarts and upgrades, mount the data file from your host into the container. Add a volumes entry to your docker-compose.yml:
docker-compose.yml
services:
  restreamer:
    image: ghcr.io/kbats183/simple-rtmp-restreamer:latest
    ports:
      - "6070:6070"
      - "1935:1935"
    volumes:
      - ./simple-rtmp-restreamer.data.json:/app/simple-rtmp-restreamer.data.json
Before starting the container for the first time, create an empty file on the host so Docker does not create a directory in its place: 
touch simple-rtmp-restreamer.data.json
If you do not mount the data file as a volume, your stream configuration is lost every time the container restarts or is recreated. Always mount this file in production deployments.

​
Back up your configuration

To back up your stream configuration, copy the JSON file to a safe location: 
cp simple-rtmp-restreamer.data.json simple-rtmp-restreamer.data.backup.json
The file is plain JSON and can be stored in version control, copied to remote storage, or included in an automated backup routine.

​
Restore from a backup

To restore a previous configuration, replace the data file and restart the container: 
cp simple-rtmp-restreamer.data.backup.json simple-rtmp-restreamer.data.json
docker compose restart restreamer

​
Data file format

The file contains a JSON array of stream objects. Each stream has a name and a list of restream targets: 
[
  {
    "name": "my-stream",
    "targets": [
      { "name": "YouTube", "url": "rtmp://a.rtmp.youtube.com/live2/YOUR_KEY" }
    ]
  }
]
You can edit this file manually to bulk-import streams or targets, then restart the container to apply changes.
