-${{ content_synopsis }} This image will run netbird from a single image (not multiple) rootless and distroless for more security. Due to the nature of a single image and not multiple, you see in the [compose.yaml](https://github.com/11notes/docker-netbird/blob/master/compose.yaml) example that an ```entrypoint:``` has been defined. This image also needs some environment variables present in your **.env** file. This image's defaults (management.json) as well as the example **.env** are to be used with Keycloak as your IdP and Traefik as your reverse proxy. You can however provide your own **management.json** file and use any IdP you like and use a different reverse proxy.
