Can someone help me with the Ingress controller

Question

Good morning guys!

I took down a staging environment for a product on GCP and ran the deployment scripts again, the backend and frontend service has been setup.

I have an ingress resource and a load balancer up, however, the service is not running. A look at the production app revealed there was something like an ingress controller.

I really don't understand all these and how it was created. Can someone help me understand because I have not seen anything online that makes it clear for me.

Hey, a small explanation on ingress controller

Ingress is split into two main parts – Ingress resources and ingress controller

• Ingress resources-  Ingress Resources defines how you want the requests to the services to be routed.  It contains the main routing rules.

• Ingress controller - What ingress controller does is, it reads the ingress resource’s information and process the data accordingly. So basically, ingress resources contain the rules to route the traffic and ingress controller routes the traffic.

Hope this helps!
