Deployment
Warning
If you can't login, make sure you are accessing the service over localhost or https otherwise set HTTP_ALLOWED=true
# docker-compose.yml services: convertx: image: ghcr.io/c4illin/convertx container_name: convertx restart: unless-stopped ports: - "3000:3000" environment: - PUID=1000 # user id for file permissions (should match your host user id) - JWT_SECRET=aLongAndSecretStringUsedToSignTheJSONWebToken1234 # will use randomUUID() if unset # - HTTP_ALLOWED=true # uncomment this if accessing it over a non-https connection volumes: - ./data:/app/data
or
docker run -p 3000:3000 -e PUID=1000 -e PGID=1000 -v ./data:/app/data ghcr.io/c4illin/convertx
Ensure PUID and PGID match your host user (id -u and id -g) to avoid permission issues on the mapped ./data volume. If you get unable to open database file, verify the directory permissions or run chown -R $USER:$USER path on the path you choose.
Then visit http://localhost:3000 in your browser and create your account. Don't leave it unconfigured and open, as anyone can register the first account.
Environment variables
All are optional, JWT_SECRET is recommended to be set.
