Red Hat OpenShift Container Platform provides developers and IT organizations with a hybrid cloud application platform for deploying both new and existing applications on secure, scalable resources with minimal configuration and management. OpenShift Container Platform supports a wide selection of programming languages and frameworks, such as Java, JavaScript, Python, Ruby, and PHP.
Built on Red Hat Enterprise Linux (RHEL) and Kubernetes, OpenShift Container Platform provides a more secure and scalable multitenant operating system for today’s enterprise-class applications, while delivering integrated application runtimes and libraries. OpenShift Container Platform enables organizations to meet security, privacy, compliance, and governance requirements.
About this release
OpenShift Container Platform (RHSA-2024:xxxx) is now available. This release uses Kubernetes 1.30 with CRI-O runtime. New features, changes, and known issues that pertain to OpenShift Container Platform 4.18 are included in this topic.
OpenShift Container Platform 4.18 clusters are available at https://console.redhat.com/openshift. With the Red Hat OpenShift Cluster Manager application for OpenShift Container Platform, you can deploy OpenShift Container Platform clusters to either on-premises or cloud environments.
OpenShift Container Platform 4.18 is supported on Red Hat Enterprise Linux (RHEL) 8.8-8.10, and on Red Hat Enterprise Linux CoreOS (RHCOS) 9.4.
You must use RHCOS machines for the control plane, and you can use either RHCOS or RHEL for compute machines. RHEL machines are deprecated in OpenShift Container Platform 4.16 and will be removed in a future release.
Starting from OpenShift Container Platform 4.14, the Extended Update Support (EUS) phase for even-numbered releases increases the total available lifecycle to 24 months on all supported architectures, including x86_64, 64-bit ARM (aarch64), IBM Power® (ppc64le), and IBM Z® (s390x) architectures.
Beyond this, Red Hat also offers a 12-month additional EUS add-on, denoted as Additional EUS Term 2, that extends the total available lifecycle from 24 months to 36 months. The Additional EUS Term 2 is available on all architecture variants of OpenShift Container Platform.
Commencing with the OpenShift Container Platform 4.14 release, Red Hat is simplifying the administration and management of Red Hat shipped cluster Operators with the introduction of three new life cycle classifications; Platform Aligned, Platform Agnostic, and Rolling Stream. These life cycle classifications provide additional ease and transparency for cluster administrators to understand the life cycle policies of each Operator and form cluster maintenance and upgrade plans with predictable support boundaries. For more information, see OpenShift Operator Life Cycles.
OpenShift Container Platform is designed for FIPS. When running Red Hat Enterprise Linux (RHEL) or Red Hat Enterprise Linux CoreOS (RHCOS) booted in FIPS mode, OpenShift Container Platform core components use the RHEL cryptographic libraries that have been submitted to NIST for FIPS 140-2/140-3 Validation on only the x86_64, ppc64le, and s390x architectures.
For more information about the NIST validation program, see Cryptographic Module Validation Program. For the latest NIST status for the individual versions of RHEL cryptographic libraries that have been submitted for validation, see Compliance Activities and Government Standards.
OpenShift Container Platform layered and dependent component support and compatibility
The scope of support for layered and dependent components of OpenShift Container Platform changes independently of the OpenShift Container Platform version. To determine the current support status and compatibility for an add-on, refer to its release notes. For more information, see the Red Hat OpenShift Container Platform Life Cycle Policy.

When you run Cloud-native Network Functions (CNF) latency tests on an OpenShift Container Platform cluster, the test can sometimes return results greater than the latency threshold for the test; for example, 20 microseconds for
cyclictesttesting. This results in a test failure. (OCPBUGS-42328)
Asynchronous errata updates
Security, bug fix, and enhancement updates for OpenShift Container Platform 4.18 are released as asynchronous errata through the Red Hat Network. All OpenShift Container Platform 4.18 errata is available on the Red Hat Customer Portal. See the OpenShift Container Platform Life Cycle for more information about asynchronous errata.
Red Hat Customer Portal users can enable errata notifications in the account settings for Red Hat Subscription Management (RHSM). When errata notifications are enabled, users are notified through email whenever new errata relevant to their registered systems are released.
|
Red Hat Customer Portal user accounts must have systems registered and consuming OpenShift Container Platform entitlements for OpenShift Container Platform errata notification emails to generate. |
This section will continue to be updated over time to provide notes on enhancements and bug fixes for future asynchronous errata releases of OpenShift Container Platform 4.18. Versioned asynchronous releases, for example with the form OpenShift Container Platform 4.18.z, will be detailed in subsections. In addition, releases in which the errata text cannot fit in the space provided by the advisory will be detailed in subsections that follow.
|
For any OpenShift Container Platform release, always review the instructions on updating your cluster properly. |
RHSA-2024:XXXX - OpenShift Container Platform 4.18.0 image release, bug fix, and security update advisory
