Just as a heads up, in the 2.3 release we're adding support to define connection methods on a per image/OS basis.
We have a lot of the code work done and it's fairly stable in the repository. See VCL-30 and VCL-526 https://issues.apache.org/jira/browse/VCL-30 https://issues.apache.org/jira/browse/VCL-526 The basic flow would be to start the service and open the defined port in the OS level firewall.
