External DNS

Configure external DNS servers for Kubernetes clusters.

This is a new Kubernetes Incubator project and will incorporate features from the following existing projects:

• Kops DNS Controller
• Mate
• wearemolecule/route53-kubernetes

Features

• External DNS should be able to create/update/delete records on Cloud Provider DNS server
• Configurable Cloud Provider
• External DNS should take the ownership of the records created by it
• Support Kubernetes Service(type=Loadbalancer), Ingress and NodePorts
• Support DNS naming via annotations
• Fault Tolerance
• Support weighted records annotations - allow different resources share same hostname, and respective weighted records should be created.
• Support multiple hosted zones - therefore External DNS should be able to create records as long as there exist a hosted zone matching the desired hostname

Minor Features

• Should do smart cloud provider updates, i.e. Cloud Provider API should be called only when necessary
• High Availability - should be possible to run multiple instances of External DNS
• Should be able to monitor resource changes via K8S API for quick updates
• New DNS record sources (e.g. TPRs) and targets (e.g. Azure DNS) should be pluggable and easy to add
