Kubernetes Ingress
Kubernetes Ingress is an API object that manages external access to services within a Kubernetes cluster, typically HTTP and HTTPS traffic. It provides routing rules, load balancing, SSL/TLS termination, and name-based virtual hosting, acting as a traffic controller for incoming requests. Ingress resources define how traffic should be routed to different services based on hostnames, paths, or other criteria.
Developers should learn Kubernetes Ingress when deploying web applications or APIs in Kubernetes to expose services externally without using NodePort or LoadBalancer services directly, which can be less flexible. It is essential for managing complex routing scenarios, such as hosting multiple domains on a single cluster, implementing canary deployments, or securing traffic with TLS certificates. Use cases include microservices architectures, multi-tenant applications, and cloud-native deployments requiring scalable ingress management.
