Ingress Controller

Jan 1, 0001

Definition

An Ingress Controller is a specialized load balancer for Kubernetes environments that manages external access to services within a cluster, typically via HTTP/HTTPS. It interprets Ingress resources, which define rules for routing external HTTP/S traffic to internal services. Ingress Controllers can provide additional features such as SSL termination, path-based routing, and virtual host-based routing, enhancing the security and efficiency of traffic management in Kubernetes.
