port-forward
==========================
Forward your traffic behind NAT, expose certain services in containers etc.

## Usage

Define the following environment variables to configure port-forwarding.

Variable | Description | Optional
-------- | ----------- | --------
REMOTE_HOST | IP or address of the host you want to forward traffic to | no
REMOTE_PORT | Port on remote host to forward traffic to | yes (80)
LOCAL_PORT | Port where container listens | yes (80)

The `socat` process within the container will listen by default to port 80, use `-p`docker
flag to map the port of the local machine where it will listen to traffic to be forwarded.


```bash
docker run \
	--name port-forward \
	-d \
	--restart always \
	--publish 81:80 \
	--ENV REMOTE_HOST=example.com \
	--ENV REMOTE_PORT=82 \
	--ENV LOCAL_PORT=80 \
	newnius/port-forward
```
