An Ingress in Kubernetes is a collection of rules that allow inbound connections to reach services. Attend this webinar to learn when to use Ingress controllers. It will cover the types of ingress controllers along with relevant use cases. We will walk you through a demo of configuring Ingress for a web application.

4. Recap - Service Types
● ClusterIP
○ Service is reachable only from inside of the cluster.
● NodePort
○ Service is reachable through <NodeIP>:NodePort address.
● LoadBalancer
○ Service is reachable through an external load balancer mapped to
<NodeIP>:NodePort address

6. Overview of Ingress
● An Ingress is a collection of rules that allow inbound
connections to reach the cluster services
● Configured to expose services through
○ External URLs
○ Load Balancers
○ SSL-terminated endpoints
○ Name-based virtual hosting

8. Demo
Exploring Ingress with GKE

9. Ingress in Kubernetes
● Special type of controller deployed within the cluster
● A daemon, deployed as a Kubernetes Pod, that watches
the apiserver's /ingresses endpoint for updates to the
Ingress resource
● Fundamentally different from other controllers
