NodePort and LoadBalancer
Explore how NodePort and LoadBalancer service types work in Kubernetes to expose applications beyond the cluster. Learn how NodePort opens ports on all nodes for external access, while LoadBalancer automates cloud load balancer provisioning. Understand their roles in routing traffic to pods for efficient and stable application access.
We'll cover the following...
NodePort
This is the type of service we have been using so far, and it builds on top of the ClusterIP type. You can think of it as an extension, so everything we can do with a ClusterIP, we can also do with a NodePort service.
In addition to allowing applications that are running in our cluster to talk to each other, it will also allow us to expose our application to the outside world. It works by opening a port on all the worker nodes we have in our cluster, and then redirecting requests received ...
