Container-based Collector - DNS issues in 35.001

Question

We have found that our 35.001 collector, based on logicmonitor/collector:latest has a /etc/resolv.conf using Google (8.8.8.8 / 8.8.4.4), as well as a domain setting.  This seems to be set at install time, based on the /etc/resolv.conf file timestamps.This prevents intra-cluster DNS lookups.Has anyone else experienced this?

To answer my own question (and hopefully useful to someone else!), we had set (in the Deployment yaml):hostNetwork: true...in order to get Netflow working.  This causes the DNS settings to be copied from the container host.
