第1章 Update options with Red Hat build of MicroShift and Red Hat Device Edge
Updates are supported on Red Hat build of MicroShift beginning with the General Availability version 4.14.
1.1. Red Hat Device Edge updates
You can update Red Hat Enterprise Linux for Edge (RHEL for Edge) images or Red Hat Enterprise Linux (RHEL) with or without updating the Red Hat build of MicroShift version if the version combination is supported. See the following table for details:
Red Hat Device Edge release compatibility matrix
Red Hat Enterprise Linux (RHEL) and MicroShift work together as a single solution for device-edge computing. You can update each component separately, but the product versions must be compatible. Supported configurations of Red Hat Device Edge use verified releases for each together as listed in the following table:
| RHEL Version(s) | MicroShift Version | Supported MicroShift Version → Version Updates |
|---|---|---|
| 9.4 | 4.17 | 4.17.1 → 4.17.z |
| 9.4 | 4.16 | 4.16.0 → 4.16.z, 4.16 → 4.17 |
| 9.2, 9.3 | 4.15 | 4.15.0 → 4.15.z, 4.15 → 4.16 on RHEL 9.4 |
| 9.2, 9.3 | 4.14 | 4.14.0 → 4.14.z, 4.14 → 4.15 or 4.14 → 4.16 on RHEL 9.4 |
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 cluster, or both. For more information, see the Red Hat Device Edge release compatibility matrix.
