Zookeeper Image

[d3bt3ch]

What ZooKeeper image is used by the Strimzi operator. Does the Strimzi operator also manages the ZooKeeper cluster? Can we use an existing ZooKeeper instance with Kafka CRD?

Strimzi always manages its own ZooKeeper cluster that is dedicated to a given Kafka cluster. So you cannot bring your own ZooKeeper or use Strimzi to manage ZooKeeper for some of your other applications.

It is using its own container image - basically, we use our own Kafka image as the Kafka binaries contain ZooKeeper as part of them.

@scholzj Thanks. Also, which means even if we have two Strimzi managed Kafka clusters, there would two Zookeeper clusters. Even in such a situation no two Kafka cluster can share a single Zookeeper cluster managed by Strimzi?

[scholzj]

Correct. Each Kafka cluster has its own ZooKeeper cluster.

Thanks for resolving my query. Does the default Kafka image also comes with Zookeeper as part of them?
