MKE hardware requirements

Take careful note of the minimum and recommended hardware requirements for MKE manager and worker nodes prior to deployment.

Note

  • High availability (HA) installations require transferring files between hosts.

  • On manager nodes, MKE only supports the workloads it requires to run.

  • Windows container images are typically larger than Linux container images. As such, provision more local storage for Windows nodes and for any MSR repositories that store Windows container images.

    • 79 GB available storage for the /var partition, unpartitioned

    OR

    • 79 GB available storage, partitioned as follows:

      • 25 GB for a single /var/ partition

      • 25 GB for /var/lib/kubelet/ (for installations and future upgrades)

      • 25 GB for /var/lib/docker/

      • 4 GB for /var/lib/containerd/

  • 4 GB RAM

  • 15 GB storage for the /var/ partition

Recommended hardware requirements
