A very simple HTTP echo server with support for websockets.

• Any messages sent from a websocket client are echoed
• Visit /.ws for a basic UI to connect and send websocket messages
• Requests to any other URL will return the request headers and body

• The PORT environment variable sets the server port, which defaults to 8080
• Set the LOG_HTTP_BODY environment variable to dump request bodies to STDOUT

The examples below show a few different ways of running the server with the HTTP server bound to a custom TCP port of 10000.

make release
docker build . -t echo

To run as a container:

docker run -p 8080:8080 echo:latest --rm

or with environment variables:

docker run -e IDENTIFIER=[ID] -e LOG_HTTP_BODY=true [-e etc...] -p 8080:8080 echo:latest --rm

You can hit the application in a browser at http://0.0.0.0:8080/.ws (provided you didn't change the default port).
