User Datagram Protocol (`UDP`)

Setup your sandbox environment with Docker and Docker Compose, and clone the Envoy repository with Git.

Used to make HTTP requests.

Used to send packets.

This sandbox provides a very simple example of Envoy proxying UDP.

It also demonstrates UDP traffic stats provided by the Envoy admin endpoint.

Change directory to examples/udp in the Envoy repository.

Envoy should proxy UDP on port 10000 to an upstream server listening on port .

Envoy also provides an admin endpoint listening on port 10001.

You can use netcat to send packets to the upstream server, proxied by Envoy:

Checking the logs of the upstream server you should see the packets that you sent:
