Kubeadm init control plane endpoint1/13/2024 You can copy the kubeconfig file from the controlplane node(~/.kube/config ) to local and export the KUBECONFIG variable or directly access the cluster from the controlplane node. Run 'kubectl get nodes' on the control-plane to see this node join the cluster. * The Kubelet was informed of the new secure connection details. * Certificate signing request was sent to apiserver and a response was received. Waiting for the kubelet to perform the TLS Bootstrap. Writing kubelet environment file with flags to file "/var/lib/kubelet/kubeadm-flags.env" Writing kubelet configuration to file "/var/lib/kubelet/config.yaml" FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -o yaml' Load the br_netfilter module and let iptables see bridged traffic sudo modprobe overlay Sudo apt-mark hold kubelet kubeadm kubectl Kubeadm | kubectl | kubelet install curl -s | sudo apt-key add -Įcho "deb kubernetes-xenial main" | sudo tee /etc/apt//kubernetes.list Let's being!! Step 1 - Run this on all the machines Now that we know some of the cool features, let's set up a Kubernetes cluster on Ubuntu 20.04 machines for version 1.26.Ĥ Ubuntu 20.04 instances with ssh access to them, you can use any cloud provider to launch these instancesĮach instance should have a minimum of 4GB of ram Loadbalancers can now use multiple protocols like UDP and TCP both.ĭynamic resource allocation will let the pods use external hardware resources NodeInclusionPolicy moves to beta - this is to indicate whether to take taints/tolerations into consideration when calculating Pod Topology Spread skew. PodSchedulingReadiness - You can now specify using the new schedulinggates feature in the pod to mark the pod as SchedulingGated. metrics/slis for Kubernetes binaries for better health dashboards of Kubernetes components. Kubernetes metrics include significant improvements: The framework moves to alpha with all the metrics documented here. Not a Windows fan but I think this is also highlighted as a major feature in the release - Support for running privileged containers on windows nodes graduates to beta. Kuberentes release signing - graduates to beta and binaries now ship additional *.sig (signature) and *.cert (certificate) files side by side with the artifacts for verifying their integrity. So to work with Kubernetes 1.26, containerd 1.6.0 is required.ġ - the vSphere and Azure in-tree driver migration to CSI have graduated to Stable.Ģ - With 1.26 CSI drivers now have the option to apply the fsGroup settings during attach or mount time of the volumes.ģ - GlusterFs and OpenStack cinder in-tree storage is removed in this release. kubeadm init -image-repository=ĬRI v1alpha2 removed - kubelet will not register the node if the container runtime doesn't support CRI v1. The new release images will now be under - This will provide faster downloads and also removes a single point of failure. Kubernetes 1.26 was released four days ago a huge thanks to the release team for pulling off this awesome release!
