Certified Kubernetes Administrator (CKA) Practice Test

Kubernetes Ingress is primarily designed to manage external access to services within a Kubernetes cluster. By utilizing Ingress, users can define rules for routing external HTTP(S) traffic to the backend services based on hostnames or path-based rules, enabling efficient management of service endpoints.

Ingress acts as a bridge between the outside world and the services running inside the cluster, allowing for a single point of entry and simplifying the management of multiple services. This capability is particularly useful for applications that require load balancing, SSL termination, and path-based routing, providing a cohesive way to handle incoming traffic.

In contrast, scheduling pods on nodes is the responsibility of the Kubernetes scheduler, which ensures that pods are assigned to appropriate nodes based on resource availability and other constraints. Enforcing network policies is handled by the network plugin, allowing control over communication between services. Creating custom resources pertains to extending Kubernetes with resources not natively supported, which is accomplished through the use of Custom Resource Definitions (CRDs).
