nodepool-base

Tasks to deal with image metadata and other Nodepool cloud specific tweaks.

Name resolution

The image should have the unbound DNS resolver package installed, the nodepool-base element then configures it to forward DNS queries to:

NODEPOOL_STATIC_NAMESERVER_V4, default: 1.0.0.1 NODEPOOL_STATIC_NAMESERVER_V4_FALLBACK, default: 8.8.8.8.

If NODEPOOL_STATIC_NAMESERVER_POPULATE_IPV6 is set to 1 then the following two servers will be configured as forwarders too

NODEPOOL_STATIC_NAMESERVER_V6, default: 2606:4700:4700::1111 NODEPOOL_STATIC_NAMESERVER_V6_FALLBACK, default: 2001:4860:4860::8888

Note externally setting either of these values implies NODEPOOL_STATIC_NAMESERVER_POPULATE_IPV6=1
