Route, we recommend you add IP route(s) so Kubernetes cluster addresses go via the appropriate adapter. If you have more than one network adapter, and your Kubernetes components are not reachable on the default If these values are not unique to each node, the installation process Kubernetes uses these values to uniquely identify the nodes in the cluster. It is very likely that hardware devices will have unique addresses, although some virtual machines may have The product_uuid can be checked by using the command sudo cat /sys/class/dmi/id/product_uuid.You can get the MAC address of the network interfaces using the command ip link or ifconfig -a.Verify the MAC address and product_uuid are unique for every node You MUST disable swap in order for the kubelet to work properly. Certain ports are open on your machines.Unique hostname, MAC address, and product_uuid for every node.Full network connectivity between all machines in the cluster (public or private network is fine).2 GB or more of RAM per machine (any less will leave little room for your apps).Configure cgroup driver used by kubelet on control-plane node.Installing kubeadm, kubelet and kubectl.

Ensure iptables tooling does not use the nftables backend.Verify the MAC address and product_uuid are unique for every node.This page shows how to install the kubeadm toolbox.įor information how to create a cluster with kubeadm once you have performed this installation process, see the Using kubeadm to Create a Cluster page.
