how to set advertisedListeners in broker.conf for different broker pods , when i use pulsar in k8s，such as：
```
pulsar-cluster-broker-0
pulsar-cluster-broker-1
pulsar-cluster-broker-2
```
and broker.conf for pod: pulsar-cluster-broker-0
```
advertisedListeners=internal:pulsar://pulsar-cluster-broker-0.pulsar-cluster-broker.pulsar.svc.cluster.local:6650,external:pulsar://x.x.x.x34000
```
for pulsar-cluster-broker-1
```
advertisedListeners=internal:pulsar://pulsar-cluster-broker-1.pulsar-cluster-broker.pulsar.svc.cluster.local:6650,external:pulsar://x.x.x.x34000
```
in pulsar-broker ConfigMap value:
```
advertisedListeners: ""
```
and i can get POD_NAME in env.
```
env:
- name: POD_NAME
valueFrom:
fieldRef:
apiVersion: v1
fieldPath: metadata.name

you can customize your apply-config-from-env.py script, in `# Update values from Env` block, add some code like:
```
if k.startswith('advertisedListeners'):
v = advertisedListenersValue(os.environ['POD_NAME'])
lines[idx] = '%s=%s\n' % (k, v)
```

# add value for advertisedListeners
# in broker configmap: advertisedListeners: "internal:pulsar://%s.pulsar-cluster-broker.pulsar.svc.cluster.local:6650,external:pulsar://x.x.x.x:30012"

fine, The problem of using your own scripts to render broker.conf is simple, I struggled with the default script and didn't see the logic to handle the `advertisedListeners`， thank you , I understand !
