Hello,

It doesn't seem to be an error with the ECK, it's more like a Kubernetes issue.
If you look closer at the error message, it says:

unable to build kube config due to error: invalid configuration: no configuration has been provided, try setting KUBERNETES_MASTER environment variable

Did you try to specify the KUBERNETES_MASTER environment variable? Again, this is not an ECK/Elasticsearch issue, feel free to open an issue/question on the Kubernetes discuss https://discuss.kubernetes.io/

I used to define it. Guess what, I just didn't put a "-" and whitespaces mistake when I defined the env. No wonder I can't get it right
