nginx-echo-server

A simple openresty based image which acts as a catch-all server and echos back the request. A very poor man's version of httpbin.

Features

• HTTP and HTTPS using self signed certificates
• Echoes both request headers and body
• Accepts any URL and HTTP method

API

• /status/{httpStatus} - Responds with the given HTTP status
• /jwt - Expects a JWT token as the body and returns the decoded token (Requires the JWT_SECRET environment variable to be set)
• /websocket - WebSocket which echos the received payload. Responds to ping with pong.
• /any/path/here - Matches any other path and simply echoes back the request headers and body
