<p>I am trying to run Kafka cluster on AWS EKS cluster (v1.16). I am using bitnami helm charts.</p>

<a href="https://github.com/bitnami/charts/tree/master/bitnami/zookeeper" rel="nofollow noreferrer">https://github.com/bitnami/charts/tree/master/bitnami/zookeeper</a></p>
<p>I have deployed zookeeper ensemble successfully using below command:</p>
<pre><code>helm install zookeeper bitnami/zookeeper --set replicaCount=3 --set auth.enabled=false --set allowAnonymousLogin=true --set persistence.storageClass=ebs --set persistence.accessModes={ReadWriteOnce} --set persistence.size=1Gi --set podLabels.&quot;app\.kubernetes\.io/version&quot;=&quot;1.0&quot;
</code></pre>
<p>It outputs:</p>
<pre><code>ZooKeeper can be accessed via port 2181 on the following DNS name from within your cluster:

    zookeeper.pulse.svc.cluster.local
</code></pre>
<p>Now, I am trying to deploy Kafka cluster with below command:</p>
<pre><code>helm install kafka bitnami/kafka --set replicaCount=3 --set zookeeper.enabled=false --set externalZookeeper.servers=zookeeper.pulse.svc.cluster.local --set autoCreateTopicsEnable=true --set persistence.storageClass=ebs --set persistence.accessModes={ReadWriteOnce} --set persistence.size=1Gi --set podLabels.&quot;app\.kubernetes\.io/version&quot;=&quot;1.0&quot;
</code></pre>
<p>It outputs:</p>
<pre><code>Kafka can be accessed by consumers via port 9092 on the following DNS name from within your cluster:

    kafka.pulse.svc.cluster.local

Each Kafka broker can be accessed by producers via port 9092 on the following DNS name(s) from within your cluster:
    kafka-0.kafka-headless.pulse.svc.cluster.local
    kafka-1.kafka-headless.pulse.svc.cluster.local
    kafka-2.kafka-headless.pulse.svc.cluster.local
</code></pre>
<p>It creates 3 pods but none of the pod is able to connect to zookeeper. I am not getting what is the issue here.<br />
Kafka pod logs:</p>

<p>Please help.</p>
<p><strong>UPDATE</strong><br />
HI,
It comes out to be the Istio porxy issue. I uninstalled Istio and it worked out.

NumeroUno
<p>This works fine for me on my local cluster.  Since you are using EKS, you are most likely using <a href="https://docs.aws.amazon.com/eks/latest/userguide/cni-custom-network.html" rel="nofollow noreferrer">AWS CNI</a>(?). CNI allocates IP addresses in your VPC and if you are not allowing your security groups access to the VPC range it will not be able to access the pods. (<code>172.20.162.36:2181</code> looks like VPC address for example).</p>
<p>Another thing you can check if is if you have some NetworkPolicy preventing access:</p>
<pre class="lang-sh prettyprint-override"><code>kubectl get netpol
</code></pre>
<p>It's kind of odd that you get the <em><strong>expected</strong></em> response from Zookeeper:</p>
<pre class="lang-sh prettyprint-override"><code>curl zookeeper.pulse.svc.cluster.local:2181
curl: (52) Empty reply from server
</code></pre>
<p>So it could be possible that <code>zookeeper.pulse.svc.cluster.local</code> is resolving to an 'accessible' :2181. In any case, it looks like a firewall/network policy issue.</p>
