In order to support latency-critical and high-throughput workloads, Kubernetes offers a suite of Resource Managers. The managers aim to co-ordinate and optimise the alignment of node's resources for pods configured with a specific requirement for CPUs, devices, and memory (hugepages) resources. Hardware topology alignment policies Topology Manager is a kubelet component that aims to coordinate the set of components that are responsible for these optimizations. The overall resource management ...| Kubernetes

This page shows how to safely drain a node, optionally respecting the PodDisruptionBudget you have defined. Before you begin This task assumes that you have met the following prerequisites: You do not require your applications to be highly available during the node drain, or You have read about the PodDisruptionBudget concept, and have configured PodDisruptionBudgets for applications that need them. (Optional) Configure a disruption budget To ensure that your workloads remain available during...| Kubernetes
When you specify a Pod, you can optionally specify how much of each resource a container needs. The most common resources to specify are CPU and memory (RAM); there are others. When you specify the resource request for containers in a Pod, the kube-scheduler uses this information to decide which node to place the Pod on. When you specify a resource limit for a container, the kubelet enforces those limits so that the running container is not allowed to use more of that resource than the limit ...| Kubernetes
Overview This tutorial will show you how to start a multi-node clusters on minikube and deploy a service to it. Prerequisites minikube 1.10.1 or higher kubectl Caveat Default host-path volume provisioner doesn’t support multi-node clusters (#12360). To be able to provision or claim volumes in multi-node clusters, you could use CSI Hostpath Driver addon. Tutorial Start a cluster with 2 nodes in the driver of your choice: minikube start --nodes 2 -p multinode-demo 😄 [multinode-demo] miniku...| minikube
This page contains an overview of the various feature gates an administrator can specify on different Kubernetes components. See feature stages for an explanation of the stages for a feature. Overview Feature gates are a set of key=value pairs that describe Kubernetes features. You can turn these features on or off using the --feature-gates command line flag on each Kubernetes component. Each Kubernetes component lets you enable or disable a set of feature gates that are relevant to that comp...| Kubernetes
