Define a default CPU resource limits for a namespace, so that every new Pod in that namespace has a CPU resource limit configured.

This page shows how to use Weave Net for NetworkPolicy. Before you begin You need to have a Kubernetes cluster. Follow the kubeadm getting started guide to bootstrap one. Install the Weave Net addon Follow the Integrating Kubernetes via the Addon guide. The Weave Net addon for Kubernetes comes with a Network Policy Controller that automatically monitors Kubernetes for any NetworkPolicy annotations on all namespaces and configures iptables rules to allow or block traffic as directed by the policies.

This page explains how to upgrade a Linux Worker Nodes created with kubeadm. Before you begin You need to have shell access to all the nodes, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts. To check the version, enter kubectl version.

Device plugins let you configure your cluster with support for devices or resources that require vendor-specific setup, such as GPUs, NICs, FPGAs, or non-volatile main memory.

This page contains guidelines for Kubernetes documentation. If you have questions about what's allowed, join the #sig-docs channel in Kubernetes Slack and ask! You can register for Kubernetes Slack at https://slack.k8s.io/. For information on creating new content for the Kubernetes docs, follow the style guide. Overview Source for the Kubernetes website, including the docs, resides in the kubernetes/website repository. Located in the kubernetes/website/content/<language_code>/docs folder, the majority of Kubernetes documentation is specific to the Kubernetes project.

This page shows how to use the update-imported-docs.py script to generate the Kubernetes reference documentation. The script automates the build setup and generates the reference documentation for a release. Before you begin Requirements: You need a machine that is running Linux or macOS. You need to have these tools installed: Python v3.7.x+ Git Golang version 1.13+ Pip used to install PyYAML PyYAML v5.1.2 make gcc compiler/linker Docker (Required only for kubectl command reference) Your PATH environment variable must include the required build tools, such as the Go binary and python.

In Kubernetes versions before v1.23, a scheduling policy can be used to specify the predicates and priorities process. For example, you can set a scheduling policy by running kube-scheduler --policy-config-file <filename> or kube-scheduler --policy-configmap <ConfigMap>. This scheduling policy is not supported since Kubernetes v1.23. Associated flags policy-config-file, policy-configmap, policy-configmap-namespace and use-legacy-policy-config are also not supported. Instead, use the Scheduler Configuration to achieve similar behavior. What's next Learn about scheduling Learn about kube-scheduler Configuration Read the kube-scheduler configuration reference (v1)

Each major Kubernetes release introduces new features that require documentation. New releases also bring updates to existing features and documentation (such as upgrading a feature from alpha to beta). Generally, the SIG responsible for a feature submits draft documentation of the feature as a pull request to the appropriate development branch of the kubernetes/website repository, and someone on the SIG Docs team provides editorial feedback or edits the draft directly.
