I have a problem with the resolution of name outside kubernetes (like google or api of service use) wouldn't update because the TTL of the records is setted to a value like 4292482298.
When kubedns' pod start the ttl is correctly setted to 300 and it is refreshed every 5 minutes.
With dig i'm monitoring the ttl count down and i'm seeing that it restart from 300 but after some days of working it change to 4292482298 that is more than 130 years.

Environment:

  • Kubernetes version v1.11.3
  • hardware configuration: vSphere
  • OS :CoreOS1855
  • Kernel 4.14.67-coreos
  • Install tools: kubespray
  • k8s-dns-kube-dns-amd64:1.14.13
