Expected behavior When I run a Kubernetes NodePort (or LoadBalancer) service, I can reach the service, probably via the host-exposed port on localhost; that is, if kubectl get services says it is a NodePort service on ports 80:31234/TCP,...
Services simply point to pods using labels. Since services are not node-specific, a service can point to a pod regardless of where it runs in the cluster at any given moment in time. By exposing a service IP address as well as a DNS service name, the application can be reached by eith...
NodePort is a type of service in Kubernetes that allocates a port on each node in the cluster. When a service is exposed as NodePort, Kubernetes automatically maps the service to the allocated port on each node. This allows external traffic to reach the service through any node’s IP addres...
