further analysis and visualization. 1.4 Kubernetes Components Kubernetes works in a master-node mode, where a master can manage a large number of nodes. Some components run only on masters, some components DEPLOYING AND SCALING KUBERNETES WITH RANCHER The master can be run in HA mode with a multi-master setup. Apart from components listed for master as shown in the above diagram, there are optional components course change this as per your use case.

This is the virtual or physical machine that hosts the Kubernetes control plane, formerly known as a master node. Server node In Rancher terminology, a server node is a Kubernetes control plane node. 4 Ready 17h v1.25.10+rke2r1 rke2-s1 Ready control-plane,etcd,master 17h v1.25.10+rke2r1 You can see that the nodes are now up.

command to download and install Helm: Option1 $ curl https://raw.githubusercontent.com/helm/helm/master/scripts /get-helm-3 | bash Option2 $ curl -sfL https://get.helm.sh/helm-v3.5.3-linux- amd64.tar successful Kubernetes cluster creation. The following output shows that all the nodes have both master and worker roles installed: $ kubectl get nodes NAME STATUS ROLES

counterintuitive. But state is still necessary to restore a failed master node and is especially important if you run a cluster with only a single master. 6.2 Security Policy & User Management • Active Directory
