<p>I have used this document for creating kafka <a href="https://kow3ns.github.io/kubernetes-kafka/manifests/" rel="nofollow noreferrer">https://kow3ns.github.io/kubernetes-kafka/manifests/</a></p>
<p>able to create zookeeper, facing issue with the creation of kafka.getting error to connect with the zookeeper.</p>
<p>this is the manifest i have used for creating
for kafka:</p>
<p><a href="https://kow3ns.github.io/kubernetes-kafka/manifests/kafka.yaml" rel="nofollow noreferrer">https://kow3ns.github.io/kubernetes-kafka/manifests/kafka.yaml</a>
for Zookeeper</p>

<a href="https://i.stack.imgur.com/Ang7w.png" rel="nofollow noreferrer">kafka deployed manifest</a></p>

<p>Your Kafka and Zookeeper deployments are running in the <code>kaf</code> namespace according to your screenshots, presumably you have set this up manually and applied the configurations while in that namespace? Neither the Kafka or Zookeeper YAML files explicitly state a namespace in metadata, so will be deployed to the active namespace when created.</p>
<p>Anyway, the Kafka deployment YAML you have is hardcoded to assume Zookeeper is setup in the <code>default</code> namespace, with the following line:</p>
<pre><code>          --override zookeeper.connect=zk-cs.default.svc.cluster.local:2181 \
</code></pre>
<p>Change this to:</p>
<pre><code>          --override zookeeper.connect=zk-cs.kaf.svc.cluster.local:2181 \
</code></pre>
<p>and it should connect. Whether that's by downloading and locally editing the YAML file etc.</p>
<p>Alternatively deploy Zookeeper into the <code>default</code> namespace.</p>
<p>I also recommend looking at other options like <a href="https://github.com/bitnami/charts/tree/master/bitnami/kafka/#installing-the-chart" rel="nofollow noreferrer">Bitnami Kafka Helm charts</a> which deploy Zookeeper as needed with Kafka, manages most of the connection details and allows for easier customisation. It is also kept far more up to date.</p>
