Kubeadm is a tool for bootstrapping and managing a Kubernetes cluster. It provides a simple way to initialize a cluster by automating the tasks required to set up the control plane, join worker nodes, and configure networking. Kubeadm also includes features such as upgrading the cluster and adding or removing nodes.
Kubeadm follows the Kubernetes API conventions and can be used with any Kubernetes distribution. It requires minimal configuration and can be used to set up a production-grade cluster in minutes. Kubeadm uses kubeadm-init for initializing the control plane, kubeadm-join for joining worker nodes, and kubeadm-upgrade for upgrading the cluster.
Kubeadm supports multiple network providers, including Calico, Flannel, Weave Net, and Cilium. It also provides options for configuring container runtimes such as Docker, Containerd, and CRI-O.
Overall, Kubeadm simplifies the process of setting up a Kubernetes cluster and makes it accessible to users without extensive knowledge of Kubernetes internals.
