+If you are running Grafana Agent in a Docker container and you want to expose the API outside the Docker container, you must change the default HTTP listen address from `127.0.0.1:12345` to a valid network interface address.
+You can change the HTTP listen address with the command-line flag: `-server.http.address=0.0.0.0:12345`.
+For more information, refer to the [Server](https://grafana.com/docs/agent/latest/static/configuration/flags/#server) command-line flag documentation.

+You must also publish the port in Docker. Refer to [Published ports](https://docs.docker.com/network/#published-ports) in the Docker documentation for more information.
