Sonatype CLM Server - Installation And Deployment Guide

One option to expose the CLM server via https, is to use an external server like Apache httpd or nginx and configure it for reverse proxying the external connections via https to internal http connection. This reverse proxy can be installed on the same server as the Sonatype CLM server or a different server and numerous tutorials for this setup are available on the internet.

A second option is to directly configure SSL support for Dropwizard.
