Chapter 3. Updating RPMs manually
Updating Red Hat build of MicroShift for non-image-based Red Hat Enterprise Linux (RHEL) systems requires updating the RPMs. For patch releases, such as 4.20.1 to 4.20.2, simply update the RPMs. For minor-version release updates, add the step of enabling the update repository by using your subscription manager.
You can back up application data as needed and move the data copy to a secure location when using any update type.
3.1. Applying patch updates using RPMs
Updating MicroShift on non rpm-ostree systems such as Red Hat Enterprise Linux (RHEL) requires downloading then updating the RPMs. For example, use the following procedure to upgrade from 4.20.1 to 4.20.2.
Keeping component versions in a supported configuration of Red Hat Device Edge can require updating MicroShift and RHEL at the same time. Ensure that your version of RHEL is compatible with the version of MicroShift you are updating to, especially if you are updating MicroShift across two minor versions. Otherwise, you can create an unsupported configuration, break your node, or both. For more information, see the Red Hat Device Edge release compatibility matrix.
Prerequisites
- The system requirements for installing MicroShift have been met.
- You have root user access to the host.
- The version of MicroShift you have is compatible to upgrade to the version you are preparing to use.
- You have verified that your host operating system is compatible with the version of MicroShift you are preparing to install.
- You have completed a system backup.
You cannot downgrade MicroShift with this process. Downgrades are not supported.
Procedure
Update the MicroShift RPMs by running the following command:
sudo dnf update microshift
$ sudo dnf update microshiftCopy to Clipboard Copied! Toggle word wrap Toggle overflow Restart MicroShift by running the following command:
sudo systemctl restart microshift
$ sudo systemctl restart microshiftCopy to Clipboard Copied! Toggle word wrap Toggle overflow
The greenboot system health check runs on this update type, but does not perform any actions. If the update fails, an error message appears with the instruction to check the logs.
3.2. Applying minor-version updates with RPMs
Updating a MicroShift minor version on non rpm-ostree systems such as Red Hat Enterprise Linux (RHEL) requires downloading then updating the RPMs. For example, use the following procedure to update from 4.18 to 4.20.
Keeping component versions in a supported configuration of Red Hat Device Edge can require updating MicroShift and RHEL at the same time. Ensure that your version of RHEL is compatible with the version of MicroShift you are updating to, especially if you are updating MicroShift across two minor versions. Otherwise, you can create an unsupported configuration, break your node, or both. For more information, see the Red Hat Device Edge release compatibility matrix.

Procedure
For all lifecycles, enable the repository for the release you want to update to by running the following command:
sudo subscription-manager repos \ --enable rhocp-4.20-for-rhel-9-$(uname -m)-rpms \ --enable fast-datapath-for-rhel-9-$(uname -m)-rpms$ sudo subscription-manager repos \ --enable rhocp-4.20-for-rhel-9-$(uname -m)-rpms \ --enable fast-datapath-for-rhel-9-$(uname -m)-rpmsCopy to Clipboard Copied! Toggle word wrap Toggle overflow For extended support (EUS) releases, also enable the EUS repositories by running the following command:
sudo subscription-manager repos \ --enable rhel-9-for-$(uname -m)-appstream-eus-rpms \ --enable rhel-9-for-$(uname -m)-baseos-eus-rpms$ sudo subscription-manager repos \ --enable rhel-9-for-$(uname -m)-appstream-eus-rpms \ --enable rhel-9-for-$(uname -m)-baseos-eus-rpmsCopy to Clipboard Copied! Toggle word wrap Toggle overflow Avoid unintended future updates into an unsupported configuration by locking your operating system version with the following command:
sudo subscription-manager release --set=9.6
$ sudo subscription-manager release --set=9.6Copy to Clipboard Copied! Toggle word wrap Toggle overflow Update the MicroShift RPMs by running the following command:
sudo dnf update microshift
$ sudo dnf update microshiftCopy to Clipboard Copied! Toggle word wrap Toggle overflow Reboot the host to apply updates by running the following command:
sudo systemctl reboot
$ sudo systemctl rebootCopy to Clipboard Copied! Toggle word wrap Toggle overflow
The system health check runs on this update type, but does not perform any actions. If the update fails, an error message appears with the instruction to check the logs.
Verification
Check if the health checks exited with a successful boot by running the following command:
sudo systemctl status greenboot-healthcheck
$ sudo systemctl status greenboot-healthcheckCopy to Clipboard Copied! Toggle word wrap Toggle overflow Check the health check logs by running the following command:
sudo journalctl -u greenboot-healthcheck
$ sudo journalctl -u greenboot-healthcheckCopy to Clipboard Copied! Toggle word wrap Toggle overflow
