A very simple HTTP echo server with support for web-sockets.

• Any messages sent from a web-socket client are echoed.
• Visit /.ws for a basic UI to connect and send web-socket messages.
• Requests to any other URL will return the request headers and body.
• The PORT environment variable sets the server port.
• No TLS support yet :(

To run as a container:

docker run --detach -P jmalloc/echo-server

To run as a service:

docker service create --publish 8080 jmalloc/echo-server
