Pods IP address from inside a container in the pod

Question

I'm trying to run Aerospike cluster in kubernetes and the config files need its own IP address. How do I get pods IP address from inside a container in the pod.

Answer 1

Make sure that your pod yaml file has an environment variable that sets the ip address. You can do this by adding the config blog defined bellow:

 env:
    - name: MY_POD_NAME
      valueFrom:
        fieldRef:
          fieldPath: metadata.name
    - name: MY_POD_NAMESPACE
      valueFrom:
        fieldRef:
          fieldPath: metadata.namespace
    - name: MY_POD_IP
      valueFrom:
        fieldRef:
          fieldPath: status.podIP

Recreate the pod/rc and then try

echo $MY_POD_IP
