kubectl not getting all pods

Question

I am using Google Cloud Platform, and I have two different kubernetes clusters running on GKE. Now these clusters are zonal clusters, and are running on different zones. the issue is when I am using the cloud shell, kubectl get pods is getting pods from another cluster. I have used kubectl config set-cluster xxx to set the cluster, but still, the other pods are showing only.

If kubectl get pods returns pods from another cluster, your kubectl configuration is probably pointing to the other cluster.

You can check the current context (current cluster) kubectl is using with: kubectl config current-context.

Note that, as the GKE documentation highlights:

When you create a cluster using the Google Cloud console or using gcloud CLI from a different computer, your environment's kubeconfig file is not updated. Additionally, if a project team member uses gcloud CLI to create a cluster from their computer, their kubeconfig is updated but yours is not. The kubeconfig entry contains either:

Your credentials as shown in gcloud auth list, or

The application default credentials, if configured.

To generate a kubeconfig context in your environment, ensure that you have the container.clusters.get permission. The least-privileged IAM role that provides this permission is container.clusterViewer.

To generate a kubeconfig context for a specific cluster, run the following command:

gcloud container clusters get-credentials CLUSTER_NAME

Replace CLUSTER_NAME with the name of your cluster.

If the target cluster is not running in the default zone or region, or if you did not set a default zone or region, you need to supply the region (--region=REGION) or zone (--zone=ZONE) in the command.

Note: Running gcloud container clusters get-credentials also changes the current context for kubectl to that cluster.
