The end of support date only applies to minor versions, for example 7.3.x. Maintenance versions follow the same two year lifecycle of the minor version. For example, the end of support for Confluent Platform 3.3.4 ends on August 1, 2020.
The two year support policy is standard. End of support is extended one year for Platinum support agreements.
Platinum support does not extend the support timeline for Confluent for Kubernetes (CFK) / Operator.
You can apply your Platinum support contract to the Confluent Platform components deployed by CFK / Operator when both of the following conditions are true:
- You are on a currently supported version of CFK / Operator. See Supported versions of CFK.
- The Confluent Platform version you want to use is compatible with a currently supported version of CFK / Operator.
Each version of Confluent Platform includes several component services which are only compatible in that specific Confluent Platform version. There are exceptions, including clients and Confluent Control Center, which can be used across versions. All services included in Confluent Platform are supported, including Apache Kafka® and its subcomponents: Kafka brokers, Apache ZooKeeper™, Java and Scala clients, Kafka Streams, and Kafka Connect.
Preview Releases¶
Features designated with “preview” status in this documentation are not intended for production use. They should only be used for evaluation and non-production testing purposes or to provide feedback to Confluent.
Confluent encourages customers to submit questions and suggestions about preview features using the Confluent Support Portal.
Preview features are not “Supported Software” under Confluent’s support policies.
Additionally, Confluent may make changes to preview user experience and APIs before they are released for production use.
Operating Systems¶
Confluent Platform and clients support these operating systems.
It is recommended that you run Confluent Platform across uniform OS, Confluent Platform, and JAVA versions.
Important
Confluent Platform is not currently supported on ARM64 processors for production workloads.
| Operating System | 7.3.x | 7.2.x | 7.1.x | 7.0.x | 6.2.x | 6.1.x | 6.0.x | 5.5.x |
|---|---|---|---|---|---|---|---|---|
| RHEL/CentOS 7.x (deprecated *) | yes | yes | yes | yes | yes | yes | yes | yes |
| RHEL/CentOS 8.x | yes | yes | yes | yes | yes | yes | yes | no |
| Debian 9 (stretch) (deprecated *) | yes | yes | yes | yes | yes | yes | yes | yes |

| Ubuntu 20.04 LTS (focal) | yes | yes | yes | yes | no | no | no | no |
* Deprecated: Support for these OS versions are deprecated because they have reached their end of life. The OS is currently supported for Confluent Platform 7.3, but this support may be removed in a future release.
- SELinux
- Confluent Platform is supported on RHEL, CentOS, Debian and Ubuntu Linux Operating Systems. Confluent is not accountable for Security-Enhanced Linux (SELinux) policy development, support, or enforcement. If you experience issues running Confluent Platform with SELinux enabled on a supported Linux Operating System, contact your OS provider for assistance.
- Windows
Windows is not currently supported for Confluent Platform.
Windows 8.1 and later, as well as Windows 2016 and later, are supported by the C/C++ and .NET clients.
- macOS
- macOS 10.14 and later is supported for testing and development purposes only.
- File descriptors
- For the file descriptor requirement for Kafka, see File Descriptors and mmap.
- ulimit
Control Center requires many open RocksDB files. Set the
ulimitfor the number of open files to a minimum value of 16384 using theulimit -ncommand.For the other Confluent Platform components, specifically Schema Registry and Replicator, you can leave the
ulimitas the OS default.- RHEL with TLS
When installing Confluent Platform on RHEL8 with TLS encryption, you must add DH Key Size JVM Parameters for each component. For more information, see Strong crypto defaults in RHEL 8 and deprecation of weak crypto algorithms.
Set the following component-level environment variables to the argument:
- Control Center:
CONTROL_CENTER_OPTS=-Djdk.tls.ephemeralDHKeySize=2048 - Schema Registry:
SCHEMA_REGISTRY_OPTS=-Djdk.tls.ephemeralDHKeySize=2048 - Kafka, ZooKeeper, and Connect:
KAFKA_OPTS=-Djdk.tls.ephemeralDHKeySize=2048 - REST Proxy:
KAFKAREST_OPTS=-Djdk.tls.ephemeralDHKeySize=2048 - ksqlDB:
KSQL_OPTS=-Djdk.tls.ephemeralDHKeySize=2048
- Control Center:
Java¶
Java 17 is the recommended version in this version of Confluent Platform. Java 11 and Java 8 are also supported.
Java 8 is now deprecated in Confluent Platform, and the support for Java 8 will be removed in Confluent Platform 8.0.
From a security perspective, we recommend the latest released patch version as older freely available versions have disclosed security vulnerabilities.
Use the latest released patch version of Java to ensure known security vulnerabilities are addressed.
Java 9 and 10 are not supported in Confluent Platform as those versions are short-term rapid release versions.
For more information about Java versions, see Java Version History.
You need to separately install the correct version of Java before you start the Confluent Platform installation process.
We recommend using the full JDK to help Confluent Support with troubleshooting and to provide better support when you experience issues with Confluent Platform.
OpenJDK, Zulu OpenJDK, Eclipse Temurin (formerly known as AdoptOpenJDK), and Oracle are supported with Confluent Platform.

- [1] Cannot configure Control Center to monitor multiple Kafka clusters.
- [2] Cannot have RBAC enabled on the source or target cluster.
- [3] Cannot enable both SASL and mTLS for ZooKeeper out of the box. See Ansible Troubleshooting for enabling both authentication modes using config overrides.
- [4] Only available for new installations. Supports central management of RBAC across multiple Kafka clusters.
- [5] Only available for new installations. Does not support centrally managing ACLs across multiple Kafka clusters.
- [6] Does not support ZooKeeper configuration Secrets.
You can manually configure the features marked as Not available outside of the scope of Ansible Playbooks for Confluent Platform. If you take the hybrid installation approach, refer to the appropriate installation document in Confluent documentation to ensure your install path of mixing Ansible installation and manual installation is supported.
Docker¶
If you are not using a higher-level container orchestration system like Kubernetes, Confluent Platform Docker images are available for use directly with Docker. Docker version 1.11 or later running on a supported operating system is required to use the Docker images.
