diskimage-builder's Issues

RStudio HTTP server should respond over IPv6

The RStudio image starts a HTTP server on port 80. This server only listens on IPv4, even when the instance has IPv6 connectivity. This should be fixed.

Add missing ConfigDrive support

The images that we build for SWITCHengines users are currently configured to use only the Ec2 data source. This is configured (at least on Debian/Ubuntu) in /etc/cloud/cloud.cfg.d/91-dib-cloud-init-datasources.cfg, which includes something like

datasource_list: [  Ec2, None ]

Some users may want to use ConfigDrive as a data source instead. Possible reasons include paranoia (the unsecured HTTP-over-IPv4 access to the metadata server might be intercepted), or the fact that IPv6-only instances cannot access the metadata server at all. Therefore it would seem better to change the default to e.g.

datasource_list: [  ConfigDrive, Ec2, None ]

For those users who don't user config drives (that is the vast majority of users now), this shouldn't change anything. The hope is that cloud-init will quickly and discreetly (e.g. without generating scary error messages) determine that no ConfigDrive source is present, and fall back to the usual Ec2 data source. That would need to be verified.

Base specialized images on Ubuntu Xenial

RStudio and Zeppelin are based on Ubuntu. So far they still use Ubuntu 14.04 (Trusty). Both RStudio and Zeppelin support Ubuntu 16.04 (Xenial) just fine. It's time for us to upgrade.
