In upgrading to MKE 3.5.x, be aware that MKE versions 3.5.0 - 3.5.5 each run a version of etcd that is older than the version Mirantis includes with MKE 3.4.14. As such, MKE 3.4.14 can only be upgraded to MKE 3.5.6 or later. Parallel to this, it is necessary to target MKE 3.6.1 or later when upgrading from MKE 3.5.6 and later to 3.6.x.

The etcd component, by design, will not accept a downgrade of itself.

Known issues

  • Use of Node Feature Discovery (NFD) Pods can result in a crash loop in Linux systems that run MCR 20.10.8 and earlier (moby/moby#42836).

    As a workaround, update MCR to version 20.10.9 or later.

  • As MKE does not support cgroup v2 on Linux platforms, RHEL 9.0 users will be unable to use the software due to cgroup v2 default enablement.

    As a workaround, RHEL 9.0 users must disable cgroup v2.
