You can define your container with ```--net=your_network``` option. +With the addition of [overlay networking](https://docs.docker.com/engine/userguide/networking/get-started-overlay/) in Docker 1.9, your `nginx-proxy` container may need to connect to backend containers on multiple networks. By default, if you don't pass the `--net` flag when your `nginx-proxy` container is created, it will only be attached to the default `bridge` network. This means that it will not be able to connect to containers on networks other than `bridge`. -If your proxy try to access at a container in an unattached network, the request is successful. +If you want your `nginx-proxy` container to be attached to a different network, you must pass the `--net=my-network` option in your `docker create` or `docker run` command. At the time of this writing, only a single network can be specified at container creation time. To attach to other networks, you can use the `docker network connect` command after your container is created: -#### Connect Another Network - -In current Docker release (1.9), you can create a container with only one network.
