I'm not having any luck in changing the name of a worker node in AWS EKS. I have not been able to find any documentation regarding how the node is named by default.
Currently my nodes are named as follows, for example
NAME STATUS ROLES AGE VERSION
ip-10-241-111-216.us-west-2.compute.internal Ready 44m v1.14.7-eks-1861c5I've tried passing in --hostname-override through the user data but it didn't seem to have any effect.
This is a known limitation in AWS EKS and its discussed this GitHub issue and it's still open.
Few other cloud providers respect the --hostname-override flag with some conditions. Those can be found in official Kubernetes documentation.
