Connecting to a cluster

Ensure you're properly authenticated to your cluster.

You can do this by running kubectl cluster-info and verifying that you get a response. Follow the guide here to install kubectl. The response looks something like

➜  kube-knots git:(main) ✗ kubectl cluster-info
Kubernetes control plane is running at https://127.0.0.1
GLBCDefaultBackend is running at https://127.0.0.1/api/v1/namespaces/kube-system/services/default-http-backend:http/proxy
KubeDNS is running at https://127.0.0.1/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
KubeDNSUpstream is running at https://127.0.0.1/api/v1/namespaces/kube-system/services/kube-dns-upstream:dns/proxy
Metrics-server is running at https://127.0.0.1/api/v1/namespaces/kube-system/services/https:metrics-server:/proxy
