Description: A node port is a type of service that exposes a port on each node of a cluster, allowing external traffic to access the service. This feature is fundamental in microservices and container architectures, where the goal is to facilitate communication between different components of a distributed application. By exposing a port on each node, it ensures that the service is accessible from any point in the cluster, improving availability and scalability. Node ports are particularly useful in environments where load balancing is required, as they allow efficient distribution of traffic among available nodes. Additionally, this configuration simplifies service management, as administrators can access them without needing to know the specific location of each container within the cluster. In summary, node ports are a key tool for optimizing connectivity and performance in distributed systems, facilitating interaction between users and the services running in a cluster.
