⁠tcp-proxy-docker

⁠Description

Simple utility to relay tcp traffic to a specific host and port.

It can prove useful if you want to temporarily bind a running container port to your host.

⁠Usage

tcp-proxy host port

⁠Examples

To relay all TCP connections on your port 1234 to my.cool.host:8080:

docker run -it --rm -p 1234:8080 hpello/tcp-proxy my.cool.host 8080

To access a container running on the compose_default network, with name api and port 8080:

docker run -it --rm --network compose_default -p 1234:8080 hpello/tcp-proxy api 8080

⁠Listen port

By default, tcp-proxy will listen on the same port as the one specified.

This can be overriden by setting the LISTEN_PORT environment variable.
