Unable to fetch broker ID using kubectl command

I want to fetch the list of broker ids in a cluster using kubectl exec command.

I am able to run the commands from inside the pod and fetch the list of broker ids, however I need to find the list without having to go inside.

I am using kafka helm charts from incubator and Kubernetes distribution which comes along with docker for Mac.

kubectl exec hissing-warthog-kafka-1 -- /usr/bin/zookeeper-shell hissing-warthog-zookeeper:2181 <<< "ls /brokers/ids"

Expected result: Welcome to ZooKeeper! JLine support is enabled

WATCHER::

WatchedEvent state:SyncConnected type:None path:null [zk: hissing-warthog-zookeeper:2181(CONNECTED) 0] ls /brokers/ids [0, 1, 2]

Actual result: Connecting to hissing-warthog-zookeeper:2181 Welcome to ZooKeeper! JLine support is enabled

WATCHER::

WatchedEvent state:SyncConnected type:None path:null [zk: hissing-warthog-zookeeper:2181(CONNECTED) 0]

It should work in following way:

kubectl exec hissing-warthog-kafka-1 -- /usr/bin/zookeeper-shell hissing-warthog-zookeeper:2181 -c ls /brokers/ids

Hope this helps.
