--- reviewers: - bgrant0607 - mikedanese title: Install and Set Up kubectl content_template: templates/task --- {{% capture overview %}} Use the Kubernetes command-line tool, [kubectl](/docs/user-guide/kubectl/), to deploy and manage applications on Kubernetes. Using kubectl, you can inspect cluster resources; create, delete, and update components; and look at your new cluster and bring up example apps. {{% /capture %}} {{% capture prerequisites %}} Use a version of kubectl that is the same version as your server or later. Using an older kubectl with a newer server might produce validation errors. {{% /capture %}} ## Install kubectl Here are a few methods to install kubectl. {{% capture steps %}} ## Install kubectl binary via native package management {{< tabs name="kubectl_install" >}} {{< tab name="Ubuntu, Debian or HypriotOS" codelang="bash" >}} apt-get update && apt-get install -y apt-transport-https curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add - cat </etc/apt/sources.list.d/kubernetes.list deb http://apt.kubernetes.io/ kubernetes-xenial main EOF apt-get update apt-get install -y kubectl {{< /tab >}} {{< tab name="CentOS, RHEL or Fedora" codelang="bash" >}}cat < /etc/yum.repos.d/kubernetes.repo [kubernetes] name=Kubernetes baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64 enabled=1 gpgcheck=1 repo_gpgcheck=1 gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg EOF yum install -y kubectl {{< /tab >}} {{< /tabs >}} ## Install with snap on Ubuntu kubectl is available as a [snap](https://snapcraft.io/) application. 1. If you are on Ubuntu or one of other Linux distributions that support [snap](https://snapcraft.io/docs/core/install) package manager, you can install with: sudo snap install kubectl --classic 2. Run `kubectl version` to verify that the version you've installed is sufficiently up-to-date. ## Install with Homebrew on macOS 1. If you are on macOS and using [Homebrew](https://brew.sh/) package manager, you can install with: brew install kubectl 2. Run `kubectl version` to verify that the version you've installed is sufficiently up-to-date. ## Install with Powershell from PSGallery 1. If you are on Windows and using [Powershell Gallery](https://www.powershellgallery.com/) package manager, you can install and update with: Install-Script -Name install-kubectl -Scope CurrentUser -Force install-kubectl.ps1 [-DownloadLocation ] If no Downloadlocation is specified, kubectl will be installed in users temp Directory 2. The installer creates $HOME/.kube and instructs it to create a config file 3. Updating re-run Install-Script to update the installer re-run install-kubectl.ps1 to install latest binaries ## Install with Chocolatey on Windows 1. If you are on Windows and using [Chocolatey](https://chocolatey.org) package manager, you can install with: choco install kubernetes-cli 2. Run `kubectl version` to verify that the version you've installed is sufficiently up-to-date. 3. Configure kubectl to use a remote Kubernetes cluster: cd C:\users\yourusername (Or wherever your %HOME% directory is) mkdir .kube cd .kube New-Item config -type file Edit the config file with a text editor of your choice, such as Notepad for example. ## Download as part of the Google Cloud SDK kubectl can be installed as part of the Google Cloud SDK. 1. Install the [Google Cloud SDK](https://cloud.google.com/sdk/). 2. Run the following command to install `kubectl`: gcloud components install kubectl 3. Run `kubectl version` to verify that the version you've installed is sufficiently up-to-date. ## Install kubectl binary via curl {{< tabs name="kubectl_install_curl" >}} {{% tab name="macOS" %}} 1. Download the latest release with the command: ``` curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/darwin/amd64/kubectl ``` To download a specific version, replace the `$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)` portion of the command with the specific version. For example, to download version {{< param "fullversion" >}} on MacOS, type: ``` curl -LO https://storage.googleapis.com/kubernetes-release/release/{{< param "fullversion" >}}/bin/darwin/amd64/kubectl ``` 2. Make the kubectl binary executable. ``` chmod +x ./kubectl ``` 3. Move the binary in to your PATH. ``` sudo mv ./kubectl /usr/local/bin/kubectl ``` {{% /tab %}} {{% tab name="Linux" %}} 1. Download the latest release with the command: ``` curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl ``` To download a specific version, replace the `$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)` portion of the command with the specific version. For example, to download version {{< param "fullversion" >}} on Linux, type: ``` curl -LO https://storage.googleapis.com/kubernetes-release/release/{{< param "fullversion" >}}/bin/linux/amd64/kubectl ``` 2. Make the kubectl binary executable. ``` chmod +x ./kubectl ``` 3. Move the binary in to your PATH. ``` sudo mv ./kubectl /usr/local/bin/kubectl ``` {{% /tab %}} {{% tab name="Windows" %}} 1. Download the latest release {{< param "fullversion" >}} from [this link](https://storage.googleapis.com/kubernetes-release/release/{{< param "fullversion" >}}/bin/windows/amd64/kubectl.exe). Or if you have `curl` installed, use this command: ``` curl -LO https://storage.googleapis.com/kubernetes-release/release/{{< param "fullversion" >}}/bin/windows/amd64/kubectl.exe ``` To find out the latest stable version (for example, for scripting), take a look at [https://storage.googleapis.com/kubernetes-release/release/stable.txt](https://storage.googleapis.com/kubernetes-release/release/stable.txt). 2. Add the binary in to your PATH. {{% /tab %}} {{< /tabs >}} ## Configure kubectl In order for kubectl to find and access a Kubernetes cluster, it needs a [kubeconfig file](/docs/tasks/access-application-cluster/configure-access-multiple-clusters/), which is created automatically when you create a cluster using kube-up.sh or successfully deploy a Minikube cluster. See the [getting started guides](/docs/setup/) for more about creating clusters. If you need access to a cluster you didn't create, see the [Sharing Cluster Access document](/docs/tasks/access-application-cluster/configure-access-multiple-clusters/). By default, kubectl configuration is located at `~/.kube/config`. ## Check the kubectl configuration Check that kubectl is properly configured by getting the cluster state: ```shell kubectl cluster-info ``` If you see a URL response, kubectl is correctly configured to access your cluster. If you see a message similar to the following, kubectl is not correctly configured or not able to connect to a Kubernetes cluster. ```shell The connection to the server was refused - did you specify the right host or port? ``` For example, if you are intending to run a Kubernetes cluster on your laptop (locally), you will need a tool like minikube to be installed first and then re-run the commands stated above. If kubectl cluster-info returns the url response but you can't access your cluster, to check whether it is configured properly, use: ```shell kubectl cluster-info dump ``` ## Enabling shell autocompletion kubectl includes autocompletion support, which can save a lot of typing! The completion script itself is generated by kubectl, so you typically just need to invoke it from your profile. Common examples are provided here. For more details, consult `kubectl completion -h`. ### On Linux, using bash To add kubectl autocompletion to your current shell, run `source <(kubectl completion bash)`. To add kubectl autocompletion to your profile, so it is automatically loaded in future shells run: ```shell echo "source <(kubectl completion bash)" >> ~/.bashrc ``` ### On macOS, using bash On macOS, you will need to install bash-completion support via [Homebrew](https://brew.sh/) first: ```shell ## If running Bash 3.2 included with macOS brew install bash-completion ## or, if running Bash 4.1+ brew install bash-completion@2 ``` Follow the "caveats" section of brew's output to add the appropriate bash completion path to your local .bashrc. If you've installed kubectl using the [Homebrew instructions](#install-with-homebrew-on-macos) then kubectl completion should start working immediately. If you have installed kubectl manually, you need to add kubectl autocompletion to the bash-completion: ```shell kubectl completion bash > $(brew --prefix)/etc/bash_completion.d/kubectl ``` The Homebrew project is independent from Kubernetes, so the bash-completion packages are not guaranteed to work. ### Using Zsh If you are using zsh edit the ~/.zshrc file and add the following code to enable kubectl autocompletion: ```shell if [ $commands[kubectl] ]; then source <(kubectl completion zsh) fi ``` Or when using [Oh-My-Zsh](http://ohmyz.sh/), edit the ~/.zshrc file and update the `plugins=` line to include the kubectl plugin. ```shell source <(kubectl completion zsh) ``` {{% capture whatsnext %}} [Learn how to launch and expose your application.](/docs/tasks/access-application-cluster/service-access-application-cluster/) {{% /capture %}}
