红帽全球峰会第 2 章 Updating RPMs on a RHEL for Edge system
You can update MicroShift on Red Hat Enterprise Linux for Edge (RHEL for Edge) by embedding the new version of MicroShift on a new operating system image.
2.1. MicroShift updates on an RHEL for Edge system
Updating MicroShift on a Red Hat Enterprise Linux for Edge (RHEL for Edge) system requires building a new RHEL for Edge image containing the new version of MicroShift and any associated optional RPMs. After you create the rpm-ostree image with MicroShift embedded, you can boot into that operating system image.
The procedures are the same for minor-version and patch updates. For example, use the same steps to upgrade from 4.18 to 4.19 or from 4.19.2 to 4.19.3. The following details apply:
- Back up and system rollback are automatic with this update type.
- You can use the following workflow to update applications running in the MicroShift cluster. Ensure compatibilities between the application and the adjacent versions of MicroShift and RHEL for Edge before starting an update.
Downgrades other than automatic rollbacks are not supported. The following procedure is for updates only.
重要The steps you use depends on how your existing deployment is set up. The following procedure outlines the general steps you can take, with links to the RHEL for Edge documentation. The RHEL for Edge documentation is your resource for specific details on building an updated operating system image.
