hello I want to ask a question , I want to deploy one zookeeper cluster , I want to get pod names ending with 0-N numbers by env “valueFrom” , for example:  
I deployed three pods named zookeeper through statefulset mode. Their three pod names are zookeeper-0, zookeeper-1 and zookeeper-2. How do I get the final 0, 1 and 2?  
I found that I can only get the pod-name. Here is how I got it. Can anyone help me find out how to get the number?

```
      **env:**

```

\*\* - name: ZOO\_SERVER\_ID\*\*  
\*\* valueFrom:\*\*  
\*\* fieldRef:\*\*  
\*\* fieldPath: metadata.labels[‘[statefulset.kubernetes.io/pod-name](http://statefulset.kubernetes.io/pod-name)’]\*\*
