AWS cloud provider forces the hostname, or at least the node name, to be the same as AWS' PrivateDnsName, this leads to the node being removed if a different node name is used.

It should be allowed to use any name as the node name and map it to a tag.

Is there any problem with this? I can provide a PR. It's really cumbersome to use ip-x-x-x-x.region.compute.internal as it doesn't pair with the rest of my infrastructure.

Environment:

• Kubernetes version (use kubectl version): 1.7.5
• Cloud provider or hardware configuration: AWS
• OS: Arch Linux
• Kernel (e.g. uname -a): Linux ip-10-0-50-10 4.12.8-1-ec2 Unit test coverage in Kubelet is lousy. (~30%) #1 SMP Mon Aug 21 22:43:04 PDT 2017 x86_64 GNU/Linux
