Red Hat SummitChapter 10. Supported Configurations
Supported configurations for the Streams for Apache Kafka 2.7 release.
10.1. Supported platforms
The following platforms are tested for Streams for Apache Kafka 2.7 running with Kafka on the version of OpenShift stated.
| Platform | Version | Architecture |
|---|---|---|
| Red Hat OpenShift Container Platform | 4.12 to 4.16 | x86_64, ppc64le (IBM Power), s390x (IBM Z and IBM® LinuxONE), aarch64 (64-bit ARM) |
| Red Hat OpenShift Container Platform disconnected environment | Latest | x86_64, ppc64le (IBM Power), s390x (IBM Z and IBM® 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) | Latest | x86_64 |
| Red Hat MicroShift | Latest | x86_64 |
| Red Hat OpenShift Local | 2.13-2.19 (OCP 4.12), 2.20-2.28 (OCP 4.13), 2.29-2.33 (OCP 4.14), 2.34-2.38 (OCP 4.15), 2.39 and newer (OCP 4.16) | x86_64 |
OpenShift Local is a limited version of Red Hat OpenShift Container Platform (OCP). Use only for development and evaluation on the understanding that some features may be unavailable.
Unsupported features
- Red Hat MicroShift does not support Kafka Connect’s build configuration for building container images with connectors.
- IBM Z and IBM® LinuxONE s390x architecture does not support Streams for Apache Kafka OPA integration.
FIPS compliance
Streams for Apache Kafka 2.7.0 is designed for FIPS. Streams for Apache Kafka container images are based on RHEL 9.2, which has been 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.
OpenShift Container Platform 4.12 is the last version to support FIPS 140-2. Given the uncertainty surrounding the validation timeline for future OpenShift versions by NIST, Streams for Apache Kafka will be supported on OpenShift 4.12 until further notice.
10.2. 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. Clients are supported for use with Streams for Apache Kafka 2.7 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® 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 2.7.0. 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.
10.3. 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
Apache ZooKeeper is supported solely as an implementation detail of Apache Kafka and should not be modified for other purposes. Additionally, the cores or vCPU allocated to ZooKeeper nodes are not included in subscription compliance calculations. In other words, ZooKeeper nodes do not count towards a customer’s subscription.
10.4. Additional supported features
- Kafka Bridge
- Drain Cleaner
- Cruise Control
- Distributed Tracing
- Streams for Apache Kafka Console (technology preview)
- Streams for Apache Kafka Proxy (technology preview)
Streams for Apache Kafka Console and Streams for Apache Kafka Proxy are not production-ready. For the technology previews, they have been tested on x86 and amd64 only.
See also, Chapter 12, Supported integration with Red Hat products.
10.5. 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.
