• The startup script will auto-discover a public and private IP address, which can be environmentally overridden;
• The startup script will also accept a JSON_CONFIG environment variable containing a JSON formatted string with a config key array of lines to add to the generated coturn configuration file;
• There is presently support compiled in for sqlite3, redis, mysql, and postgresql;
• Mongo support is commented out, as it adds 130M to the image size.
