Kubernetes Ingress

Kubernetes Ingress is an API object that allows developers to expose their apps and govern external access by giving http/s routing rules to services within a Kubernetes cluster. It can help to simplify production setups by providing a simple way to implement traffic routing rules rather than having to create specialized load balancers or manually expose each service within a node.

When To Use Kubernetes Ingress

• Ingress gateway is a network component that resides at the mesh’s boundary and handles ingress traffic.
• The set of routing rules known as Kubernetes ingress controls how outside users may access services that are hosted within a Kubernetes cluster.
• A load balancer operates outside of a cluster while pods operate inside of it in a typical Kubernetes application. After receiving connections from the internet, the load balancer directs traffic to an edge proxy located inside your cluster.
• Traffic is then routed into your pods by means of this edge proxy. Because it is frequently set using ingress resources in Kubernetes, the edge proxy is also referred to as an ingress controller. Nevertheless, it may also be configured with custom resource definitions (CRDs) or annotations.

Kubernetes is an open-source container orchestration system designed to automate software deployment, scalability, and administration. Kubernetes, ingress and egress are two concepts that refer to how traffic enters and departs a cluster. Ingress in Kubernetes at its most basic. Ingress is the process of directing external traffic into the Kubernetes cluster. In other words, it serves as an entrance point for incoming traffic to the cluster’s services.
