Chapter 1. MicroShift 4.15 release notes
Red Hat build of MicroShift (MicroShift) provides developers and IT organizations with small-form-factor and edge computing delivered as an application that customers can deploy on top of their managed Red Hat Enterprise Linux (RHEL) devices at the edge. Built on OpenShift Container Platform and Kubernetes, MicroShift provides an efficient way to operate single-node clusters in low-resource edge environments.
MicroShift is designed to make control plane restarts economical and be lifecycle-managed as a single unit by the operating system. Updates, roll-backs, and configuration changes consist of simply staging another version in parallel and then - without relying on a network - flipping to and from that version and restarting.
1.1. About this release
Version 4.15 of MicroShift includes new features and enhancements. MicroShift was introduced as Generally Available with MicroShift 4.14. Update to the latest version of MicroShift to receive all of the latest features, bug fixes, and security updates. This release uses Kubernetes 1.28 with the CRI-O container runtime. New features, changes, and known issues that pertain to MicroShift are included in this topic.
You can deploy MicroShift clusters to either on-premise, cloud, or disconnected environments.
MicroShift 4.15 is supported on Red Hat Enterprise Linux for Edge (RHEL for Edge) and Red Hat Enterprise Linux (RHEL) 9.2 and 9.3.
For lifecycle information, see the MicroShift Life Cycle Policy.
1.2. New features and enhancements
This release adds improvements related to the following components and concepts.
1.2.1. Red Hat Enterprise Linux (RHEL)
- MicroShift now runs on Red Hat Enterprise Linux (RHEL) versions 9.2 and 9.3. Compatibility with RHEL 9.3 is an enhancement for MicroShift version 4.15.
MicroShift uses crun and Control Group v2 (cgroup v2). If workloads rely on the cgroup file system layout, they might need to be updated to be compatible with cgroup v2.
- If you run third-party monitoring and security agents that depend on the cgroup file system, update the agents to versions that support cgroup v2.
- If you run cAdvisor as a standalone DaemonSet for monitoring pods and containers, update it to v0.43.0 or later.
- If you deploy Java applications with JDK, ensure you are using JDK 11.0.16 and later or JDK 15 and later, which fully support cgroup v2.
1.2.2. Updating
Updates for both minor releases and patch releases are supported.
1.2.2.1. The following updates are supported
The following list provides update details:
- MicroShift offers in-place updates on RHEL for Edge systems with automatic system rollback capabilities and automatic back up and restore functions.
- Updates of the RPMs on a non-OSTree system such as RHEL are also supported.
- Updates from the 4.14 version are supported.
1.2.2.2. Version logged at start up
Previously, MicroShift did not log its version at start up. The absence of version information made debugging certain scenarios difficult because the update path was unknown. Now, the MicroShift version is logged at start up and available with commands such as journalctl -u microshift | grep "Version"
. (OCPBUGS-19540)
1.2.3. Installation
1.2.3.1. Sample blueprints now included
The microshift-release-info
RPM now contains sample blueprints that can be used for image building. The blueprints include both MicroShift RPM packages and container image references. See Adding the MicroShift service to a blueprint for more information.
1.2.4. Support
1.2.4.1. Getting the etcd version
Previously, you could not query for the etcd version included with MicroShift. Now, the microshift-etcd version
command outputs the MicroShift version and the base version of the etcd database. See The etcd service for more information.
1.2.5. Networking
1.2.5.1. Networking documentation enhancements
Various networking documentation improvements are now available in the MicroShift release.
- Network features with their customization status. A new detailed table of the networking features and their customizations that are accessible in a MicroShift instance are described in MicroShift networking customization matrix.
- Network topology updates. Extensive examples of the Network topology available in your MicroShift instance are also updated, see Network topology.
- Auditing exposed ports examples. The MicroShift documentation now includes procedures on auditing exposed network ports and viewing port log settings. The updated documentation can be viewed in Auditing exposed network ports.
- Adding and closing ports. This release also improved the documentation for adding and closing ports and services in your MicroShift firewall, see Using optional port settings.
- Network policies introduction. With this release, an introduction to setting network policies has been added to the MicroShift documentation. More details are expected to follow in z-stream releases. See Creating network policies
1.2.5.2. Configuring MicroShift on disconnected hosts
You can configure your network settings to run MicroShift on a fully disconnected host. This feature is also enabled in MicroShift version 4.14. For more information, see Configuring network settings for fully disconnected hosts.
1.2.6. Running Applications
1.2.6.1. Operator Lifecyle Manager
With this release, you can use Operator Lifecyle Manager (OLM) to create, apply, and administer add-on Operators. See Using Operator Lifecycle Manager with MicroShift
1.3. Deprecated and removed features
Some features available in previous releases of MicroShift have been deprecated or removed.
Deprecated functionality is still included in MicroShift and continues to be supported; however, it will be removed in a future release of this product and is not recommended for new deployments. For the most recent list of major functionality deprecated and removed within MicroShift 4.15, refer to the tables below. Additional details for more functionality that has been deprecated and removed are listed after the table.
In the following tables, features are marked with the following statuses:
- Available

1.4. Bug fixes
Installation
-
Previously, the
microshift-release-info
RPM depended on themicroshift
RPM. With this release, you can download and install themicroshift-release-info
RPM independently for use in image building. (OCPBUGS-22854) -
Previously, the Greenboot health check script printed outputs for some checks that were not picked up by
journald
, resulting in missing log entries when running thejournalctl -u greenboot-healthcheck
command. With this release, the production of logs by the Greenboot healthcheck has been fixed so that all outputs are linked to thesystemd
unit, making them easily available to read. (OCPBUGS-20037) -
Previously, the MicroShift clean-up script failed if CRI-O services were not present or not running. This prevented MicroShift and its dependencies from fully uninstalling. It also prevented the clean-up script from running on a system with a new installation of the
microshift
RPM that had not started. With this release, the MicroShift clean-up script skips the CRI-O steps if the service is not running, reports that status, and continues with clean-up activities. (OCPBUGS-22936) -
Previously, the Greenboot health check reported a
RED
status when the Logical Volume Manager Storage (LVMS) component was disabled because no volume groups (VGs) were present. Because volume groups are not required for MicroShift, the health check should reportGREEN
without VGs. Now, when LVMS is disabled, the Greenboot health check skips the check for theopenshift-storage
namespace and reportsGREEN
status. (OCPBUGS-25689)
Networking
-
Whenever
advertiseAddress
is configured with an IP address, any network interfaces must also be configured. Previously, manually setting theadvertiseAddress
in the MicroShiftconfig.yaml
to the IP address value that is expected to be set by default, but not manually setting the same IP address for thebr-ex
network bridge on the host, caused theovnkube-master
container in theovnkube-master
pod to crash. With this release, the MicroShift service verifies whetheradvertiseAddress
is set in theconfig.yaml
and whether any interface has the same IP address set. If the two settings are not the same, MicroShift prints an error, for example,Advertise address: %s not present in any interface, advertiseAddress
and fails. This helps ensure the proper configuration before the system starts. (OCPBUGS-27398)
Support
-
Previously,
sos
reports created journal logs in separate files, making it difficult to correlate MicroShift and the Greenboot health check. Now the MicroShiftsos
tool includes a full system journal with an aggregated view in the same log. With this update, you can see one log with a detailed report that shows all of the enabled plugins and data from the different components and applications. (OCPBUGS-19567)
1.5. Asynchronous errata updates
Security, bug fix, and enhancement updates for MicroShift 4.15 are released as asynchronous errata through the Red Hat Network. All MicroShift 4.15 errata are available on the Red Hat Customer Portal. For more information about asynchronous errata, read the MicroShift Life Cycle.
Red Hat Customer Portal users can enable errata notifications in the account settings for Red Hat Subscription Management (RHSM). When errata notifications are enabled, you are notified through email whenever new errata relevant to your registered systems are released.
Red Hat Customer Portal user accounts must have systems registered and consuming MicroShift entitlements for MicroShift errata notification emails to generate.
This section is updated over time to provide notes on enhancements and bug fixes for future asynchronous errata releases of MicroShift 4.15. Versioned asynchronous releases, for example with the form MicroShift 4.15.z, will be detailed in the following subsections.

Bug fixes
- FIPS mode
- Previously, MicroShift used a version of the logical volume manager storage (LVMS) Container Storage Interface (CSI) provider that was not designed for FIPS compliance. This caused MicroShift to fail a FIPS validation test. With this release, the LVMS version 4.15.0 is used as the default CSI storage provider and validation passes.
- When a Red Hat Enterprise Linux (RHEL) version that uses FIPS libraries is installed and started with FIPS enabled, MicroShift containers are automatically enabled to run in FIPS mode. See Running MicroShift containers in FIPS mode.
- Update to the 4.15.2 release to apply this fix for FIPS mode.
Enhancements
- Adds OLM image references in dedicated file
-
Previously, image references for embedding MicroShift OLM in a RHEL for Edge image were part of the
microshift-olm
RPM package. The application package had to be downloaded and run to retrieve the information. With this release, image references are now in the dedicatedmicroshift-olm-release-info
RPM package for easier use. (OCPBUGS-29246)
