did you specify the right host or port? error on Kubernetes

The issue is that your kubeconfig is not right. To auto-generate it run:

gcloud container clusters get-credentials "CLUSTER NAME"

This worked for me.

Make sure your config is set to the project -

gcloud config set project [PROJECT_ID]

1. Run a checklist of the Clusters in the account:

gcloud container clusters list

2. Check the output :

NAME           LOCATION       MASTER_VERSION  MASTER_IP      MACHINE_TYPE  NODE_VE.      NUM_NODES  STATUS
alpha-cluster  asia-south1-a  1.9.7-gke.6     35.200.254.78  f1-micro      1.9.7-gke.6   3          RUNNING

3. Run the following cmd to fetch credentials for your running cluster:

gcloud container clusters get-credentials your-cluster-name --zone your-zone       --project your-project

4. The following output follows:

Fetching cluster endpoint and auth data.
kubeconfig entry generated for alpha-cluster.

5. Try checking details of the node running kubectl such as below to list all pods in the current namespace, with more details:

kubectl get nodes -o wide

Should be good to go.

I had same error, this worked for me. Run

minikube status

if the response is

type: Control Plane
host: Stopped
kubelet: Stopped
apiserver: Stopped
kubeconfig: Stopped

run minikube start

type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured

You can proceed
