Kubernetes Ingress Diagram Workflow
The detailed process is as follows:
1. Kubernetes cluster administrators deploy an Ingress Controller in Kubernetes.
2. The Ingress Controller continuously monitors changes to IngressClass and Ingress objects in the Kubernetes API Server.
3. Administrators apply IngressClass and Ingress to deploy the gateway.
4. Ingress Controller creates the corresponding ingress gateway and configures the routing rules according to the administrator’s configuration.
5. If in the cloud, the client accesses the load balancer for that ingress gateway.
6. The gateway will route the traffic to the corresponding back-end service based on the host and path in the HTTP request.
Istio supports both the Ingress and Gateway APIs. Below is an example configuration using the Istio Ingress Gateway, which will be created later using the Gateway API:
