I’ve set up a Kubernetes cluster on Google Cloud Platform (GCP) using kubeadm with the following configuration:
Cluster Setup
3 Virtual Machines (VMs) on GCP 1 Master Node and 2 Worker Nodes Installed nginx-ingress-controller and MetalLB on the Master Node
Issue
I deployed an application and exposed it as a ClusterIP service, then created an Ingress resource for this service. The Ingress shows the IP assigned by nginx-ingress-controller, but I cannot access the service through this IP from the public internet.
Steps Taken
Verified the configurations for nginx-ingress-controller and MetalLB Confirmed that MetalLB assigned the correct external IP Checked GCP firewall rules to allow external access to relevant ports
