We are trying to running an application (a java servlet that connects to guacamole server) on flexible appengine, in our troubleshooting it looks like there is a nginx proxy on the google cloud instance (the instance from which docker image is running).
Is there a way we customize the nginx configuration the google cloud instance to help resolve our issues?
Nope. The proxy is part of our infrastructure that you can't really customize. Can you be a little more specific? What are you trying to do?
