You can use kubectl to deploy applications, inspect and manage cluster resources, and view logs. For a complete list of kubectl operations, see [Overview of kubectl](/docs/reference/kubectl/overview/). {{% /capture %}} {{% capture prerequisites %}} You must use a kubectl version that is within one minor version difference of your cluster. For example, a v1.2 client should work with v1.1, v1.2, and v1.3 master. Using the latest version of kubectl helps avoid unforeseen issues. {{% /capture %}} {{% capture steps %}} ## Install kubectl on Linux ### Install kubectl binary with curl on 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 ``` 4. Test to ensure the version you installed is up-to-date: ``` kubectl version ``` ### Install using native package management {{< tabs name="kubectl_install" >}} {{< tab name="Ubuntu, Debian or HypriotOS" codelang="bash" >}} sudo apt-get update && sudo apt-get install -y apt-transport-https curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add - echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee -a /etc/apt/sources.list.d/kubernetes.list sudo apt-get update sudo 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 using other package management {{< tabs name="other_kubectl_install" >}} {{% tab name="Snap" %}} If you are on Ubuntu or another Linux distribution that support [snap](https://snapcraft.io/docs/core/install) package manager, kubectl is available as a [snap](https://snapcraft.io/) application. ```shell snap install kubectl --classic kubectl version ``` {{% /tab %}} {{% tab name="Homebrew" %}} If you are on Linux and using [Homebrew](https://docs.brew.sh/Homebrew-on-Linux) package manager, kubectl is available for [installation](https://docs.brew.sh/Homebrew-on-Linux#install). ```shell brew install kubectl kubectl version ``` {{% /tab %}} {{< /tabs >}} ## Install kubectl on macOS ### Install kubectl binary with curl on macOS 1. Download the latest release: ``` 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 ``` 4. Test to ensure the version you installed is up-to-date: ``` kubectl version ``` ### Install with Homebrew on macOS If you are on macOS and using [Homebrew](https://brew.sh/) package manager, you can install kubectl with Homebrew. 1. Run the installation command: ``` brew install kubectl ``` or ``` brew install kubernetes-cli ``` 2. Test to ensure the version you installed is up-to-date: ``` kubectl version ``` ### Install with Macports on macOS If you are on macOS and using [Macports](https://macports.org/) package manager, you can install kubectl with Macports. 1. Run the installation command: ``` sudo port selfupdate sudo port install kubectl ``` 2. Test to ensure the version you installed is up-to-date: ``` kubectl version ``` ## Install kubectl on Windows ### Install kubectl binary with curl on 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. 3. Test to ensure the version of `kubectl` is the same as downloaded: ``` kubectl version ``` {{< note >}} [Docker Desktop for Windows](https://docs.docker.com/docker-for-windows/#kubernetes) adds its own version of `kubectl` to PATH. If you have installed Docker Desktop before, you may need to place your PATH entry before the one added by the Docker Desktop installer or remove the Docker Desktop's `kubectl`. {{< /note >}} ### Install with Powershell from PSGallery If you are on Windows and using [Powershell Gallery](https://www.powershellgallery.com/) package manager, you can install and update kubectl with Powershell. 1. Run the installation commands (making sure to specify a `DownloadLocation`): ``` Install-Script -Name install-kubectl -Scope CurrentUser -Force install-kubectl.ps1 [-DownloadLocation ] ``` {{< note >}}If you do not specify a `DownloadLocation`, `kubectl` will be installed in the user's temp Directory.{{< /note >}} The installer creates `$HOME/.kube` and instructs it to create a config file 2. Test to ensure the version you installed is up-to-date: ``` kubectl version ``` {{< note >}}Updating the installation is performed by rerunning the two commands listed in step 1.{{< /note >}} ### Install on Windows using Chocolatey or Scoop To install kubectl on Windows you can use either [Chocolatey](https://chocolatey.org) package manager or [Scoop](https://scoop.sh) command-line installer. {{< tabs name="kubectl_win_install" >}} {{% tab name="choco" %}} choco install kubernetes-cli {{% /tab %}} {{% tab name="scoop" %}} scoop install kubectl {{% /tab %}} {{< /tabs >}} 2. Test to ensure the version you installed is up-to-date: ``` kubectl version ``` 3. Navigate to your home directory: ``` cd %USERPROFILE% ``` 4. Create the `.kube` directory: ``` mkdir .kube ``` 5. Change to the `.kube` directory you just created: ``` cd .kube ``` 6. Configure kubectl to use a remote Kubernetes cluster: ``` New-Item config -type file ``` {{< note >}}Edit the config file with a text editor of your choice, such as Notepad.{{< /note >}} ## Download as part of the Google Cloud SDK You can install kubectl as part of the Google Cloud SDK. 1. Install the [Google Cloud SDK](https://cloud.google.com/sdk/). 2. Run the `kubectl` installation command: ``` gcloud components install kubectl ``` 3. Test to ensure the version you installed is up-to-date: ``` kubectl version ``` ## Verifying kubectl configuration 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](https://github.com/kubernetes/kubernetes/blob/master/cluster/kube-up.sh) or successfully deploy a Minikube cluster. By default, kubectl configuration is located at `~/.kube/config`. 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 configured correctly or is 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 ``` ## Optional kubectl configurations ### Enabling shell autocompletion kubectl provides autocompletion support for Bash and Zsh, which can save you a lot of typing. Below are the procedures to set up autocompletion for Bash (including the difference between Linux and macOS) and Zsh. {{< tabs name="kubectl_autocompletion" >}} {{% tab name="Bash on Linux" %}} ### Introduction The kubectl completion script for Bash can be generated with the command `kubectl completion bash`. Sourcing the completion script in your shell enables kubectl autocompletion. However, the completion script depends on [**bash-completion**](https://github.com/scop/bash-completion), which means that you have to install this software first (you can test if you have bash-completion already installed by running `type _init_completion`). ### Install bash-completion bash-completion is provided by many package managers (see [here](https://github.com/scop/bash-completion#installation)). You can install it with `apt-get install bash-completion` or `yum install bash-completion`, etc. The above commands create `/usr/share/bash-completion/bash_completion`, which is the main script of bash-completion. Depending on your package manager, you have to manually source this file in your `~/.bashrc` file. To find out, reload your shell and run `type _init_completion`. If the command succeeds, you're already set, otherwise add the following to your `~/.bashrc` file: ```shell source /usr/share/bash-completion/bash_completion ``` Reload your shell and verify that bash-completion is correctly installed by typing `type _init_completion`. ### Enable kubectl autocompletion You now need to ensure that the kubectl completion script gets sourced in all your shell sessions. There are two ways in which you can do this: - Source the completion script in your `~/.bashrc` file: ```shell echo 'source <(kubectl completion bash)' >>~/.bashrc ``` - Add the completion script to the `/etc/bash_completion.d` directory: ```shell kubectl completion bash >/etc/bash_completion.d/kubectl ``` - If you have an alias for kubectl, you can extend shell completion to work with that alias: ```shell echo 'alias k=kubectl' >>~/.bashrc echo 'complete -F __start_kubectl k' >>~/.bashrc ``` {{< note >}} bash-completion sources all completion scripts in `/etc/bash_completion.d`. {{< /note >}} Both approaches are equivalent. After reloading your shell, kubectl autocompletion should be working. {{% /tab %}} {{% tab name="Bash on macOS" %}} ### Introduction The kubectl completion script for Bash can be generated with `kubectl completion bash`. Sourcing this script in your shell enables kubectl completion. However, the kubectl completion script depends on [**bash-completion**](https://github.com/scop/bash-completion) which you thus have to previously install. {{< warning>}} there are two versions of bash-completion, v1 and v2. V1 is for Bash 3.2 (which is the default on macOS), and v2 is for Bash 4.1+. The kubectl completion script **doesn't work** correctly with bash-completion v1 and Bash 3.2. It requires **bash-completion v2** and **Bash 4.1+**. Thus, to be able to correctly use kubectl completion on macOS, you have to install and use Bash 4.1+ ([*instructions*](https://itnext.io/upgrading-bash-on-macos-7138bd1066ba)). The following instructions assume that you use Bash 4.1+ (that is, any Bash version of 4.1 or newer). {{< /warning >}} ### Install bash-completion {{< note >}} As mentioned, these instructions assume you use Bash 4.1+, which means you will install bash-completion v2 (in contrast to Bash 3.2 and bash-completion v1, in which case kubectl completion won't work). {{< /note >}} You can test if you have bash-completion v2 already installed with `type _init_completion`. If not, you can install it with Homebrew: ```shell brew install bash-completion@2 ``` As stated in the output of this command, add the following to your `~/.bashrc` file: ```shell export BASH_COMPLETION_COMPAT_DIR="/usr/local/etc/bash_completion.d" [[ -r "/usr/local/etc/profile.d/bash_completion.sh" ]] && . "/usr/local/etc/profile.d/bash_completion.sh" ``` Reload your shell and verify that bash-completion v2 is correctly installed with `type _init_completion`. ### Enable kubectl autocompletion You now have to ensure that the kubectl completion script gets sourced in all your shell sessions. There are multiple ways to achieve this: - Source the completion script in your `~/.bashrc` file: ```shell echo 'source <(kubectl completion bash)' >>~/.bashrc ``` - Add the completion script to the `/usr/local/etc/bash_completion.d` directory: ```shell kubectl completion bash >/usr/local/etc/bash_completion.d/kubectl ``` - If you have an alias for kubectl, you can extend shell completion to work with that alias: ```shell echo 'alias k=kubectl' >>~/.bashrc echo 'complete -F __start_kubectl k' >>~/.bashrc ``` - If you installed kubectl with Homebrew (as explained [above](#install-with-homebrew-on-macos)), then the kubectl completion script should already be in `/usr/local/etc/bash_completion.d/kubectl`. In that case, you don't need to do anything. {{< note >}} the Homebrew installation of bash-completion v2 sources all the files in the `BASH_COMPLETION_COMPAT_DIR` directory, that's why the latter two methods work. {{< /note >}} In any case, after reloading your shell, kubectl completion should be working. {{% /tab %}} {{% tab name="Zsh" %}} The kubectl completion script for Zsh can be generated with the command `kubectl completion zsh`. Sourcing the completion script in your shell enables kubectl autocompletion. To do so in all your shell sessions, add the following to your `~/.zshrc` file: ```shell source <(kubectl completion zsh) ``` If you have an alias for kubectl, you can extend shell completion to work with that alias: ```shell echo 'alias k=kubectl' >>~/.zshrc echo 'complete -F __start_kubectl k' >>~/.zshrc ``` After reloading your shell, kubectl autocompletion should be working. If you get an error like `complete:13: command not found: compdef`, then add the following to the beginning of your `~/.zshrc` file: ```shell autoload -Uz compinit compinit ``` {{% /tab %}} {{< /tabs >}} {{% /capture %}} {{% capture whatsnext %}} * [Install Minikube](/docs/tasks/tools/install-minikube/) * See the [getting started guides](/docs/setup/) for more about creating clusters. * [Learn how to launch and expose your application.](/docs/tasks/access-application-cluster/service-access-application-cluster/) * 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/). * Read the [kubectl reference docs](/docs/reference/kubectl/kubectl/) {{% /capture %}}
