Software requirements

Prior to deploying MKE, consider the following software requirements:

• Run the same version of MCR 19.03.8 or higher on all nodes.

• Run Linux kernel 3.10 or higher on all nodes. For debugging purposes, the host OS kernel versions should match as closely as possible.

• Use a static IP address for each node in the cluster.

Note

MKE does not support user namespaces for nodes.
