How do I access Kubernetes API from outside?
Accessing services running on the cluster
- Access services through public IPs. Use a service with type NodePort or LoadBalancer to make the service reachable outside the cluster.
- Access services, nodes, or pods using the Proxy Verb.
- Access from a node or pod in the cluster.
How do I connect to external Kubernetes cluster?
Access from a node or pod in the cluster.
- Run a pod, and then connect to a shell in it using kubectl exec. Connect to other nodes, pods, and services from that shell.
- Some clusters may allow you to ssh to a node in the cluster. From there you may be able to access cluster services.

How to access the Kubernetes API in proxy mode?
To protect against man in the middle attacks, you’ll need to import a root cert into your browser. Using the Go or Python client libraries provides accessing kubectl in proxy mode. The following command runs kubectl in a mode where it acts as a reverse proxy. It handles locating the API server and authenticating. See kubectl proxy for more details.
