unable to access pod from external world

[nayabatir1]

apiVersion: v1
kind: Pod
metadata:
  name: nginx-pod
  labels:
    name: nginx-pod
spec:
  containers:
    - name: nginx
      image: nginx
      ports:
        - containerPort: 80

I used this yml config to create a pod. I tried to access pod through network namespace, but unable to do so resulted in connection timeout. but when curl inside the container index.html loads correctly.
