Does Kubernetes run on any architecture other than Intel/AMD64? Yes it does, since v1.3.0.
Lucas Käldström (@luxas), a general upper secondary school student, added support for ARM and ARM 64-bit to the core codebase earlier this year. Kubernetes is all about letting you choose the container runtime, the operating system, the environment (cloud vs bare metal) etc., so why wouldn’t you like to choose CPU architecture as well?

The talk demonstrates Kubernetes’ multi-architecture features in a very practical manner: by having a 10-node cluster of credit-card-sized devices with three architectures (amd64, arm and arm64) in front of the audience. The cluster is deployed with kubeadm. For the demo, a cross-platform nginx workload will be created from the dashboard, deployed to all nodes regardless of architecture, monitored via an auto-updating grafana dashboard and autoscaled by a Horizontal Pod Autoscaler while traffic is generated against the cluster’s Ingress controller. And just to make things more exciting, a node’s power cable may be unplugged by a volunteer from the audience, at any time during the heavy traffic to demonstrate Kubernetes’ auto-healing functions.
