kubelogin binary not included in Docker image for AKS Cluster with Azure AD RBAC

[kylelee24]

When you connect to an Azure Kubernetes Service (AKS) cluster through Azure CLI using az aks get-credentials, the ~/.kube/config file will use kubelogin in the command resulting in the following error:

$ ./k8sviz.sh

NOTE: This behaviour is the same when using kubectl.

I ended up just downloading kubelogin locally and then updating the Dockerfile and added it to the image and PATH. The code is not worth sharing.
