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.
tcp-proxy host port
To relay all TCP connections on your port 1234
to my.cool.host:8080
:
docker run -it --rm -p 1234:8080 ralphi2811/tcp-proxy:latest 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 ralphi2811/tcp-proxy:latest api 8080
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.
