I've developed a web application using clojure/compojure (JVM based) and while developing I tested it using embedded jetty that runs on
0.0.0.0:8080. I would now like to deploy it to run on port 80 on ubuntu. I do dynamic virtual hosting, so any request for any host that arrives on port 80 should be handled by my application.
The issues that worries me are:
- I can still run it embedded but I'm worried about running my app as root (needed for binding to port 80). I'm not sure if I can 'give up root' when in the JVM. Do I need to be concerned by this?
- besides, serving web applications is a known problem and I should be using known solutions for this (jetty or tomcat)
- but especially tomcat seems very heavy weight. Besides, I only have one application that listens to
/*and does routing internally. (with compojure/ring). What I'm trying to say with this is that tomcat by default assigns WARs to subfolders which I don't want.
So basically what I need is some very safe way of binding to port 80 on ubuntu that can with minimal interference send all requests to my app. Any ideas?
