Answer 3

Was facing the same problem with accessing GKE master from Google Cloud Shell.

Then I followed this GCloud doc to solve it.

1. Open GCloud Shell

2. Get External IP of the current GCloud Shell with:

   dig +short myip.opendns.com @resolver1.opendns.com

3. Add this External IP into the "Master authorized networks" section of the GKE cluster - with a CIDR suffix of /32

After that, running kubectl get nodes from the GCloud Shell worked right away.

Answer 4

You have to run first

minikube start

on your terminal. This will do following things for you:

 Restarting existing virtualbox VM for "minikube" ...
⌛  Waiting for SSH access ...

If you are using azure and have recently changed your password try this:

az account clear
az login

After logging in successfully:

az aks get-credentials --name project_name --resource-group resource_group_name

Now when you run

kubectl get nodes

you should see something. Also, make sure you are using the correct kubectl context.

If you use minikube then you should run, kubectl config use-context minikube If you use latest docker for desktop that comes with kubernetes then you should run, kubectl config use-context docker-for-desktop
