Chapter 12. Supported Configurations Supported configurations for the Streams for Apache Kafka 2.9 release. 12.1. Supported platforms The following platforms are tested for Streams for Apache Kafka 2.9 running with Kafka on the version of OpenShift stated. Platform Version Architecture Red Hat OpenShift Container Platform 4.14 and later x86_64, ppc64le (IBM Power), s390x (IBM Z and IBM(R) LinuxONE), aarch64 (64-bit ARM) Red Hat OpenShift Container Platform disconnected environment Latest x86_64, ppc64le (IBM Power), s390x (IBM Z and IBM(R) LinuxONE), aarch64 (64-bit ARM) Red Hat OpenShift Dedicated Latest x86_64 Microsoft Azure Red Hat OpenShift (ARO) Latest x86_64 Red Hat OpenShift Service on AWS (ROSA) Includes ROSA with hosted control planes (HCP) Latest x86_64 Red Hat build of MicroShift Latest x86_64 Unsupported features Red Hat MicroShift does not support Kafka Connect's build configuration for building container images with connectors. IBM Z and IBM(R) LinuxONE s390x architecture does not support Streams for Apache Kafka OPA integration. FIPS compliance Streams for Apache Kafka is designed for FIPS. Streams for Apache Kafka container images are based on RHEL 9.2, which contains cryptographic modules submitted to NIST for approval. To check which versions of RHEL are approved by the National Institute of Standards and Technology (NIST), see the Cryptographic Module Validation Program on the NIST website. Red Hat OpenShift Container Platform is designed for FIPS. When running on RHEL or RHEL CoreOS booted in FIPS mode, OpenShift Container Platform core components use the RHEL cryptographic libraries submitted to NIST for FIPS validation only on the x86_64, ppc64le (IBM Power), s390x (IBM Z), and aarch64 (64-bit ARM) architectures. For more information about the NIST validation program, see Cryptographic Module Validation Program . For the latest NIST status for the individual versions of the RHEL cryptographic libraries submitted for validation, see Compliance Activities and Government Standards . 12.2. Supported clients Only client libraries built by Red Hat are supported for Streams for Apache Kafka. Currently, Streams for Apache Kafka only provides a Java client library, which is tested and supported on kafka-clients-3.8.0.redhat-00007 and newer. Clients are supported for use with Streams for Apache Kafka 2.9 on the following operating systems and architectures: Operating System Architecture JVM RHEL and UBI 8 and 9 x86, amd64, ppc64le (IBM Power), s390x (IBM Z and IBM(R) LinuxONE), aarch64 (64-bit ARM) Java 11 (deprecated) and Java 17 Clients are tested with Open JDK 11 and 17, though Java 11 is deprecated in Streams for Apache Kafka 2.7 and will be removed in version 3.0. The IBM JDK is supported but not regularly tested against during each release. Oracle JDK 11 is not supported. Support for Red Hat Universal Base Image (UBI) versions correspond to the same RHEL version. 12.3. Supported Apache Kafka ecosystem In Streams for Apache Kafka, only the following components released directly from the Apache Software Foundation are supported: Apache Kafka Broker Apache Kafka Connect Apache MirrorMaker Apache MirrorMaker 2 Apache Kafka Java Producer, Consumer, Management clients, and Kafka Streams Apache ZooKeeper Note Apache ZooKeeper is supported solely as an implementation detail of Apache Kafka and should not be modified for other purposes. 12.4. Additional supported features Kafka Bridge Drain Cleaner Cruise Control Distributed Tracing Streams for Apache Kafka Console Streams for Apache Kafka Proxy (technology preview) Note Streams for Apache Kafka Proxy is not production-ready. For the technology preview, it has been tested on x86 and amd64 only. See also, Chapter 14, Supported integration with Red Hat products . 12.5. Console supported browsers Streams for Apache Kafka Console is supported on the most recent stable releases of Firefox, Edge, Chrome and Webkit-based browsers. 12.6. Subscription limits and core usage Cores used by Red Hat components and product operators do not count against subscription limits. Additionally, cores or vCPUs allocated to ZooKeeper nodes are excluded from subscription compliance calculations and do not count towards a subscription. 12.7. Storage requirements Streams for Apache Kafka has been tested with block storage and is compatible with the XFS and ext4 file systems, both of which are commonly used with Kafka. File storage options, such as NFS, are not compatible.
