Istio Ingress Gateway¶

The Istio Ingress Gateway is a mechanism used to expose services running within the Istio Service mesh to external traffic outside of the cluster^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__httpbin__README.md]. In a standard Istio deployment, services are secured inside the mesh and are not directly accessible from outside the cluster^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__httpbin__README.md].

Functionality¶

The Ingress Gateway acts as the entry point for inbound traffic, managing the connection between the external network and the internal services^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__httpbin__README.md]. It allows operators to define rules for how external requests reach specific services, such as the httpbin service used for testing^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__httpbin__README.md].

Usage¶

Configuring an Ingress Gateway is a primary method for enabling access to mesh services from outside the network^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__httpbin__README.md]. This process typically involves defining Gateway and VirtualService resources to route traffic correctly^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__httpbin__README.md].
