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.

The following video provides an introduction to Confluent Operator. See Introduction to Kubernetes and Confluent Operator for additional Kubernetes and Confluent Operator videos.

Features

Deploying
  • 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.
Scaling
Provides elastic scaling for new Confluent Platform components (with manual rebalancing).
Resiliency
Restores a Kafka pod with the same Kafka broker ID, configuration, and persistent storage volumes if a failure occurs.
Monitoring
  • Supports metrics aggregation using JMX/Jolokia.
  • Supports aggregated metrics export to Prometheus.

Supported environments

Confluent Operator automates the deployment and management of Confluent Platform on Kubernetes. With Confluent Platform 5.5, Confluent Operator supports Kubernetes versions 1.13 to 1.18 with any Cloud Native Computing Foundation (CNCF) conformant offering. A full list of CNCF conformant Kubernetes offerings can be found here.

Important

Red Hat OpenShift support: Red Hat includes official support for Helm 3 starting with OpenShift version 4.4. If you are using an older version of OpenShift, you need to use Helm 2 to deploy Operator and Confluent Platform 5.5. After downloading the bundle, click the v5.3.2 tab at the bottom of this page and use the Helm 2 instructions for OpenShift deployments.
