Kubectl for windows 10
This topic helps you to по этому сообщению and install, or update, the kubectl binary ffor your device. In order for kubectl to find and access a Kubernetes cluster, it needs a kubeconfig filekubectl for windows 10 is created automatically when you create a cluster using kube-up. The Windows operating system allows us to observe and save different files, execute codes, run different software, and offer a kubectl for windows 10 to associate to the internet.

Windows applications constitute a large portion of the services and applications that run in many organizations. Windows containers provide a way to encapsulate processes and package dependencies, making it easier to use DevOps practices and follow cloud native patterns for Windows applications. Organizations with investments in Windows-based applications and Linux-based applications don’t have to look for separate orchestrators to manage their workloads, leading to increased operational efficiencies across their deployments, regardless of operating system.
To enable the orchestration of Windows containers in Kubernetes, include Windows nodes in your existing Linux cluster. Scheduling Windows containers in Pods on Kubernetes is similar to scheduling Linux-based containers.
In order to run Windows containers, your Kubernetes cluster must include multiple operating systems. While you can only run the control plane on Linux, you can deploy worker nodes running either Windows or Linux.
Windows nodes are supported provided that the operating system is Windows Server This document uses the term Windows containers to mean Windows containers with process isolation.
Kubernetes does not support running Windows containers with Hyper-V isolation. Some node features are only available if you use a specific container runtime ; others are not available on Windows nodes, including:. Not all features of shared namespaces are supported. See API compatibility for more details. See Windows OS version compatibility for details on the Windows versions that Kubernetes is tested against. From an API and kubectl perspective, Windows containers behave in much the same way as Linux-based containers.
However, there are some notable differences in key functionality which are outlined in this section. Key Kubernetes elements work the same way in Windows as they do in Linux. This section refers to several key workload abstractions and how they map to Windows. A Pod is the basic building block of Kubernetes—the smallest and simplest unit in the Kubernetes object model that you create or deploy. You may not deploy Windows and Linux containers in the same Pod.
All containers in a Pod are scheduled onto a single Node where each Node represents a specific platform and architecture. The following Pod capabilities, properties and events are supported with Windows containers:.
The IdentifyPodOS feature gate needs to be enabled for this field to be recognized. If the IdentifyPodOS feature gate is enabled and you set the. For example, spec. If any of these fields is specified, the Pod will not be admitted by the API server. Services See Load balancing and Services for more details. Pods, workload resources, and Services are critical elements to managing Windows workloads on Kubernetes. However, on their own they are not enough to enable the proper lifecycle management of Windows workloads in a dynamic cloud native environment.
Some workload properties were designed for Linux, and fail to run on Windows. Container exit codes follow the same convention where 0 is success, and nonzero is failure. The specific error codes may differ across Windows and Linux. However, exit codes passed from the Kubernetes components kubelet, kube-proxy are unchanged.
The following list documents differences between how Pod container specifications work between Windows and Linux:. The following list documents differences between how Pod specifications work between Windows and Linux:. None of the Pod securityContext fields work on Windows. The node problem detector see Monitor Node Health has preliminary support for Windows.
For more information, visit the project’s GitHub page. In Linux, the cgroups and namespaces that make up a pod need a process to maintain their continued existence; the pause process provides this. Kubernetes uses pause containers to allow for worker containers crashing or restarting without losing any of the networking configuration.
Kubernetes maintains a multi-architecture image that includes support for Windows. For Kubernetes v1. The source code is available on GitHub. Microsoft maintains a different multi-architecture image, with Linux and Windows amd64 support, that you can find as mcr. This image is built from the same source as the Kubernetes maintained image but all of the Windows binaries are authenticode signed by Microsoft. The Kubernetes project recommends using the Microsoft maintained image if you are deploying to a production or production-like environment that requires signed binaries.
You need to install a container runtime into each node in the cluster so that Pods can run there. You can use ContainerD 1. Learn how to install ContainerD on a Windows node. On Windows nodes, strict compatibility rules apply where the host OS version must match the container base image OS version.
Only Windows containers with a container operating system of Windows Server are fully supported. The Kubernetes version-skew policy also applies. Your main source of help for troubleshooting your Kubernetes cluster should start with the Troubleshooting page. Some additional, Windows-specific troubleshooting help is included in this section. Logs are an important element of troubleshooting issues in Kubernetes. Make sure to include them any time you seek troubleshooting assistance from other contributors.
Follow the instructions in the SIG Windows contributing guide on gathering logs. If you have what looks like a bug, or you would like to make a feature request, please follow the SIG Windows contributing guide to create a new issue.
You should first search the list of issues in case it was reported previously and comment with your experience on the issue and add additional logs. SIG Windows channel on the Kubernetes Slack is also a great avenue to get some initial support and troubleshooting ideas prior to creating a ticket.
The kubeadm tool helps you to deploy a Kubernetes cluster, providing the control plane to manage the cluster it, and nodes to run your workloads. Adding Windows nodes explains how to deploy Windows nodes to your cluster using kubeadm. For a detailed explanation of Windows distribution channels see the Microsoft documentation. Information on the different Windows Server servicing channels including their support models can be found at Windows Server servicing channels.
