This example is equivalent to setting --kube-reserved, - Kubelet Configuration (v1beta1) Resource Types CredentialProviderConfig ImagePullIntent ImagePulledRecord Taints and Tolerations Node affinity is a property of Pods that attracts them to a set of nodes (either as a preference or a hard requirement). In Dynamic Kubelet Configuration allows you to change the configuration of each Kubelet in a live Kubernetes cluster by deploying a ConfigMap and configuring each Node to use it. The configuration is organized under the kubelet. Most times, there is a requirement to adjust values assigned to configuration This configuration must only be used with valid settings as it may cause unexpected behavior from the Kubelet if misconfigured. 10. If you don't have jq, you caninstall it via your operating system's software sources, or fetch it fromhttps://jqlang.
