[Kimchi-devel] [PATCH v4 2/3] Github #329: Kimchid, config.py.in and server.py changes

From: Daniel Henrique Barboza <danielhb(a)linux.vnet.ibm.com&gt; Two new config options were added in config.py.in - proxy_port and proxy_ssl_port - to allow more control in the ports that the proxy will bind. The defaults proxy ports are 8000 and 8001 (ssl) and default kimchid ports are 8010 and 8011. The default proxy ports were chosen to avoid editing the existing firewall configuration (now that nginx is process being exposed). Kimchid creates the proxy configuration according to user-defined parameters. server.py registers the terminate_proxy() method to a cherrypy engine that fires when the server is shut down.
