Good morning, I am trying to do something simple for a school project, to create three VMs on Azure, and then create a Kubernetes cluster with Kubeadm. I managed to create the VMs and deploy the cluster. However, when I went to do a simple test:

Kubectl create deployment nginx --image nginx
Kubectl expose deployment nginx --type NodePort --port 80

I can’t access the Nginx service. Everything seems fine from what I’ve checked, the service is running, and the pod logs don’t show any errors, so I believe the problem might be with the network.

My Azure setup is quite simple: I created a resource group, within this group I created a VNet, a subnet, three network interfaces, three Linux VMs with Ubuntu, and public IPs for all three VMs. I would like to know if there is anything I can do to address this situation?”
