Chapter 4. About updating Red Hat build of MicroShift RPMs manually
Updating Red Hat build of MicroShift for non-OSTree systems such as Red Hat Enterprise Linux (RHEL) requires downloading then updating the RPMs. For patch releases, such as 4.15.1 to 4.15.2, download and update the RPMs. For minor-version release updates, add the step of enabling the update repository using your subscription manager.
MicroShift updates are supported from one minor version to the next in sequence. For example, you must update 4.14 to 4.15.
For either upgrading with patch updates or a minor-version update, you can back up application data as needed and move the data copy to a secure location.
4.1. 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. A system reboot is not required for patch updates. For example, use the following procedure to upgrade from 4.14.0 to 4.14.1.
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
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.
4.2. 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 4.14 to 4.15.
You can only update MicroShift from one version to the next in sequence. Jumping minor versions is not supported. For example, must update 4.14 to 4.15.
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
Enable the MicroShift repositories by running the following command:
$ sudo subscription-manager repos \ --enable rhocp-4.15-for-rhel-9-$(uname -m)-rpms \ --enable fast-datapath-for-rhel-9-$(uname -m)-rpmsUpdate the MicroShift RPMs by running the following command:
$ sudo dnf update microshift
Reboot the host to apply updates by running the following command:
$ sudo systemctl reboot
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
Check the health check logs by running the following command:
$ sudo journalctl -u greenboot-healthcheck
