Requirements

See the RKE2 Support Matrix for all the OS versions that have been validated with RKE2. In general, RKE2 should work on any Linux distribution that uses systemd and iptables.

The RKE2 Windows Node (Worker) agent has been tested and validated on the following operating systems, and their subsequent non-major releases:

Open a new Powershell window with Administrator privileges

In the new Powershell window, run the following command.

This will require a reboot for the Containers feature to properly function.

When limited on CPU and RAM on the control-plane + etcd nodes, there could be limitations for the amount of agent nodes that can be joined under standard workload conditions.

It is recommended to join agent nodes in batches of 50 or less to allow the CPU to free up space, as there is a spike on node join. Remember to modify the default cluster-cidr if desiring more than 255 nodes!

This data was retrieved under specific test conditions. It will vary depending upon environment and workloads. The steps below give an overview of the test that was run to retrieve this. It was last performed on v1.27.4+rke2r1. All of the machines were provisioned in AWS with standard 20 GiB gp3 volumes.

RKE2 performance depends on the performance of the database, and since RKE2 runs etcd embeddedly and it stores the data dir on disk, we recommend using an SSD when possible to ensure optimal performance.

Typically, all outbound traffic will be allowed.
