System Requirements

Exact system requirements will be dependent upon a lot of factors, however, for the most part, any relatively modern linux operating system will fit the bill.

• Linux kernel >= 4.9.17
• systemd
• iptables (optional)

Newer versions of the kernel will enable using cilium's NodePort feature, which will replace the need to deploy kube-proxy (and therefore not need iptables also).

Dependencies

• kubelet >= 1.14.x
• containerd >= 1.2.6
• CNI >= 0.7.5
