Worker nodes can be managed with our web UI as described in manage node deployments. Once you have installed kubectl, you can also manage them via Command-Line-Interface (CLI) in order to automate creation, deletion and upgrades of nodes.
To get a list of all nodes execute:
kubectl get nodes -o wideEvery node is managed by a machine resource in the kube-system namespace, which are bundled into machineDeployments (further explanation can be found in cluster management API). To list all machineDeployment resources, execute:
kubectl get machineDeployments --namespace kube-systemWhen you want to change a machineDeployment you can edit the machineDeployment resource directly:
kubectl edit machineDeployment ${machineDeployment} --namespace kube-systemWhen a machineDeployment is edited the machineController will take care of updating the respective machines. Further explanation to the existing fields and update strategies can be found in cluster management API.
