3. Configure Kubectl

Run the ibmcloud ks clusters command to verify the terminal and setup for access to the cluster

ibmcloud ks clusters

Configure the kubectl cli available within the terminal for access to your cluster.

ibmcloud ks cluster config --cluster [cluster name]

Verify access to the Kubernetes API.

kubectl get namespace

You should see output similar to the following, if so, then your're ready to continue.
