About Confluent Operator

Confluent Operator allows you to deploy and manage Confluent Platform as a cloud-native, stateful container application on Kubernetes and OpenShift. The automation provided by Kubernetes, Operator, and Helm greatly simplifies provisioning and minimizes the burden of operating and managing Confluent Platform clusters. Operator also provides you with the portability to use Apache Kafka® in multiple provider zones and across both your private and public cloud environments.


  • Automates Confluent Platform deployment using Helm.
  • Automates Confluent Platform management.
  • Uses default Kubernetes StorageClass-based provisioners for persistent volume storage (such as Google persistent disks, AWS EBS, and Azure disk storage).
  • Automates cluster authentication and security configuration using:
    • SASL/PLAIN with TLS certificates
    • TLS two-way (mutual) authentication
    • TLS in-transit encryption for all deployed components.
Updating and upgrading
  • Provides automated rolling updates for configuration changes.
  • Provides automated rolling upgrades with no impact to Kafka availability.
Provides elastic scaling for new Confluent Platform components (with manual rebalancing).
Restores a Kafka pod with the same Kafka broker ID, configuration, and persistent storage volumes if a failure occurs.
  • Supports metrics aggregation using JMX/Jolokia.
  • Supports aggregated metrics export to Prometheus.
