ClusterIP
A ClusterIP service is the default type of service in Kubernetes. It creates a service inside the Kubernetes cluster, which can be accessed by other applications in the cluster, without allowing external access.
NodePort
A NodePort service opens a specific port on all the Nodes in the cluster, and any traffic sent to that port is forwarded to the service. The service cannot be accessed from the cluster IP.
LoadBalancer
A LoadBalancer is a standard way to expose a Kubernetes service externally so it can be accessed over the internet. If you are using Google Kubernetes Engine (GKE), this creates a Network Load Balancer with one IP address, which external users can access and are then forwarded to the relevant node in your Kubernetes cluster. A LoadBalancer can also be accessed in the same way as a ClusterIP or NodePort
