Add dnsmasq to allow us to resolve internal DNS

Opened this issue · 1 comments

I'd like to add dnsmasq to the image - principally to make it possible to forward GC2 DNS resolution to the appropriate servers. There are a few questions around this....

  • The routing inside the MAN makes routing from AWS to the DNS servers in the INFRA part of the GC2 network impossible at the moment
  • This currently is only useful when in a VPC connected to GC2, otherwise this serves no purpose, although should have no impact
  • Do we want this on all servers?
  • What cache times do we want? Disabling the caching or both positive and negative results will make this behave much like

Almost done - although should disable caching as this has unexpected effects.
