I have installed 1 master and two nodes. I have created namespace for a POD. I have launched a Yaml file provided by linux academy on a tutorial see below tutorial But I when I do my command curl it's doesn't work.

[rbo@K8SMaster ~]$ curl 10.244.1.2:80

Yaml file

apiVersion: v1
kind: Pod
metadata:
  name: examplepod
  namespace: pod-example
spec:
  volumes:
  - name: html
    emptyDir: {}
  containers:
  - name: webcontainer
    image: nginx
    volumeMounts:
    - name: html
      mountPath: /usr/share/nginx/html
  - name: filecontainer
    image: debian
    volumeMounts:
    - name: html
      mountPath: /html
    command: ["/bin/sh", "-c"]
    args:
      - while true; do
         date >> /html/index.html;
         sleep 1;
        done

Command:

    [rbo@K8SMaster ~]$ kubectl get nodes
