(Optional) Unless otherwise specified, kubeadm uses the network interface associated.

If there are more than one installed on the provisioned node, specify the -cri-socketĪrgument to kubeadm init.

(Optional) Since version 1.14, kubeadm tries to detect the container runtime on Linuxīy using a list of well known domain socket paths.

Third-party provider you choose, you might need to set the -pod-network-cidr toĪ provider-specific value.

Choose a Pod network add-on, and verify whether it requires any arguments toīe passed to kubeadm init.

Such an endpoint can be either a DNS name or an IP address of a load-balancer. To high availability you should specify the -control-plane-endpoint to set the shared endpointįor all control-plane nodes.

This crashloop is expected and normal.Īfter you initialize your control-plane, the kubelet runs normally. When you upgrade, the kubelet restarts every few seconds as it waits in a crashloop for

If you have already installed kubeadm, run apt-get update &Īpt-get upgrade or yum update to get the latest version of kubeadm. Slightly as the tool evolves, but the overall implementation should be pretty stable. The implementation of creating the cluster may change The kubeadm tool’s overall feature state is General Availability (GA). This page is written for Kubernetes v1.17. Kubernetes’ version and version skew support policy applies to kubeadm as well as to Kubernetes overall.Ĭheck that policy to learn about what versions of Kubernetes and kubeadmĪre supported.
