Synopsis Display merged kubeconfig settings or a specified kubeconfig file. You can use --output jsonpath={...} to extract specific values using a jsonpath expression. kubectl config view [flags] Examples # Show merged kubeconfig settings kubectl config view # Show merged kubeconfig settings, raw certificate data, and exposed secrets kubectl config view --raw # Get the password for the e2e user kubectl config view -o jsonpath='{.users[?(@.name == "e2e")].user.password}' Options --allow-missing-template-keys     Default: true If true, ignore any errors in templates when a field or map key is missing in the template.

Synopsis Restart a resource. Resource rollout will be restarted. kubectl rollout restart RESOURCE Examples # Restart all deployments in the test-namespace namespace kubectl rollout restart deployment -n test-namespace # Restart a deployment kubectl rollout restart deployment/nginx # Restart a daemon set kubectl rollout restart daemonset/abc # Restart deployments with the app=nginx label kubectl rollout restart deployment --selector=app=nginx Options --allow-missing-template-keys     Default: true If true, ignore any errors in templates when a field or map key is missing in the template.

Synopsis Create a deployment with the specified name. kubectl create deployment NAME --image=image -- [COMMAND] [args...] Examples # Create a deployment named my-dep that runs the busybox image kubectl create deployment my-dep --image=busybox # Create a deployment with a command kubectl create deployment my-dep --image=busybox -- date # Create a deployment named my-dep that runs the nginx image with 3 replicas kubectl create deployment my-dep --image=nginx --replicas=3 # Create a deployment named my-dep that runs the busybox image and expose port 5701 kubectl create deployment my-dep --image=busybox --port=5701 # Create a deployment named my-dep that runs multiple containers kubectl create deployment my-dep --image=busybox:latest --image=ubuntu:latest --image=nginx Options --allow-missing-template-keys     Default: true If true, ignore any errors in templates when a field or map key is missing in the template.

Synopsis Roll back to a previous rollout. kubectl rollout undo (TYPE NAME | TYPE/NAME) [flags] Examples # Roll back to the previous deployment kubectl rollout undo deployment/abc # Roll back to daemonset revision 3 kubectl rollout undo daemonset/abc --to-revision=3 # Roll back to the previous deployment with dry-run kubectl rollout undo --dry-run=server deployment/abc Options --allow-missing-template-keys     Default: true If true, ignore any errors in templates when a field or map key is missing in the template.

Synopsis Set the selector on a resource. Note that the new selector will overwrite the old selector if the resource had one prior to the invocation of 'set selector'. A selector must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 63 characters. If --resource-version is specified, then updates will use this resource version, otherwise the existing resource-version will be used. Note: currently selectors can only be set on Service objects.

Synopsis Create a LoadBalancer service with the specified name. kubectl create service loadbalancer NAME [--tcp=port:targetPort] [--dry-run=server|client|none] Examples # Create a new LoadBalancer service named my-lbs kubectl create service loadbalancer my-lbs --tcp=5678:8080 Options --allow-missing-template-keys     Default: true If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats. --dry-run string[="unchanged"]     Default: "none" Must be "none", "server", or "client". If client strategy, only print the object that would be sent, without sending it.

Synopsis The Kubernetes controller manager is a daemon that embeds the core control loops shipped with Kubernetes. In applications of robotics and automation, a control loop is a non-terminating loop that regulates the state of the system. In Kubernetes, a controller is a control loop that watches the shared state of the cluster through the apiserver and makes changes attempting to move the current state towards the desired state. Examples of controllers that ship with Kubernetes today are the replication controller, endpoints controller, namespace controller, and serviceaccounts controller.

FEATURE STATE: Kubernetes 1.34 [beta] A Kubernetes kuberc configuration file allows you to define preferences for kubectl, such as default options and command aliases. Unlike the kubeconfig file, a kuberc configuration file does not contain cluster details, usernames or passwords. On Linux / POSIX computers, the default location of this configuration file is $HOME/.kube/kuberc. The default path on Windows is similar: %USERPROFILE%\.kube\kuberc. To provide kubectl with a path to a custom kuberc file, use the --kuberc command line option, or set the KUBERC environment variable.

This page shows how to contribute to the upstream kubernetes/kubernetes project. You can fix bugs found in the Kubernetes API documentation or the content of the Kubernetes components such as kubeadm, kube-apiserver, and kube-controller-manager. If you instead want to regenerate the reference documentation for the Kubernetes API or the kube-* components from the upstream code, see the following instructions: Generating Reference Documentation for the Kubernetes API Generating Reference Documentation for the Kubernetes Components and Tools Before you begin You need to have these tools installed:
