In correlation with the end of life (EOL) for MKE 3.4.x, maintenance of this documentation set was discontinued as of 2023-APR-11. Click here for the latest MKE 3.x version documentation.

MKE 3.4 Compatibility Matrix

Mirantis Kubernetes Engine (MKE, and formerly Docker Enterprise/UCP) provides enterprises with the easiest and fastest way to deploy cloud native applications at scale in any environment.

Support for MKE is defined in the Mirantis Cloud Native Platform Subscription Services agreement.

Operating system compatibility

• As MKE functionality is dependent on MCR, MKE operating system compatibility is contingent on the operating system compatibility of the MCR versions with which a particular MKE version is compatible.

• Windows Server 2022 is not supported by MKE 3.4.x.

[1]

MKE 3.4.3 was discontinued shortly after release due to an issue that caused support dumps to fail and nodes to disconnect. Mirantis strongly recommends that customers who deployed MKE 3.4.3 upgrade to MKE 3.4.4 (or later).

[2]

Users running kernel version 4.15 or earlier on MKE 3.4.2 must either upgrade to kernel version 4.16 (or later) or upgrade to MKE 3.4.4 (or later).

[3]

MKE 3.4.1 was discontinued shortly after release due to an issue that prevents service creation from MKE client bundles and CI/CD pipeline deployment. This issue can interrupt MSR availability. Mirantis strongly recommends that customers who deployed MKE 3.4.1 upgrade to MKE 3.4.2 (or later).

Important

Be aware that RHEL 9 provides cgroup v2 by default. To run MKE on RHEL 9, you must change the platform configuration to cgroup v1.
