3.2. Applying minor-version updates with RPMs

Procedure

1. 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-4.17-for-rhel-9-$(uname -m)-rpms \
       --enable fast-datapath-for-rhel-9-$(uname -m)-rpms

2. 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

3. Avoid unintended future updates into an unsupported configuration by locking your operating system version with the following command:

   $ sudo subscription-manager release --set=9.4

4. Update the MicroShift RPMs by running the following command:

   $ sudo dnf update microshift

5. Reboot the host to apply updates by running the following command:

   $ sudo systemctl reboot

Verification

1. Check if the health checks exited with a successful boot by running the following command:

   $ sudo systemctl status greenboot-healthcheck

2. Check the health check logs by running the following command:

   $ sudo journalctl -u greenboot-healthcheck
