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’]**
