# Install and Set Up kubectl on macOS

Install and Set Up kubectl on macOSBefore you beginYou must use a kubectl version that is within one minor version difference of your cluster. For example, a v1.34 client can communicate with v1.33, v1.34, and v1.35 control planes. Using the latest compatible version of kubectl helps avoid unforeseen issues.Install kubectl on macOSThe following methods exist for installing kubectl on macOS:Install kubectl on macOSInstall kubectl binary with curl on macOSInstall with Homebrew on macOSInstall with Macports on macOSVerify kubectl configurationOptional kubectl configurations and pluginsEnable shell autocompletionInstall kubectl convert pluginInstall kubectl binary with curl on macOSDownload the latest release: curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/darwin/amd64/kubectl" curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/darwin/arm64/kubectl" Note:To download a specific version, replace the $(curl -L -s https://dl.k8s.io/release/stable.txt) portion of the command with the specific version.For example, to download version 1.34.0 on Intel macOS, type:curl -LO "https://dl.k8s.io/release/v1.34.0/bin/darwin/amd64/kubectl" And for macOS on Apple Silicon, type:curl -LO "https://dl.k8s.io/release/v1.34.0/bin/darwin/arm64/kubectl" Validate the binary (optional)Download the kubectl checksum file: curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/darwin/amd64/kubectl.sha256" curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/darwin/arm64/kubectl.sha256" Validate the kubectl binary against the checksum file:echo "$(cat kubectl.sha256) kubectl" | shasum -a 256 --check If valid, the output is:kubectl: OK If the check fails, shasum exits with nonzero status and prints output similar to:kubectl: FAILED shasum: WARNING: 1 computed checksum did NOT match Note:Download the same version of the binary and checksum.Make the kubectl binary executable.chmod +x ./kubectl Move the kubectl binary to a file location on your system PATH.sudo mv ./kubectl /usr/local/bin/kubectl sudo chown root: /usr/local/bin/kubectl Note:Make sure /usr/local/bin is in your PATH environment variable.Test to ensure the version you installed is up-to-date:kubectl version --client Or use this for detailed view of version:kubectl version --client --output=yaml After installing and validating kubectl, delete the checksum file:rm kubectl.sha256 Install with Homebrew on macOSIf you are on macOS and using Homebrew package manager, you can install kubectl with Homebrew.Run the installation command:brew install kubectl orbrew install kubernetes-cli Test to ensure the version you installed is up-to-date:kubectl version --client Install with Macports on macOSIf you are on macOS and using Macports package manager, you can install kubectl with Macports.Run the installation command:sudo port selfupdate sudo port install kubectl Test to ensure the version you installed is up-to-date:kubectl version --client Verify kubectl configurationIn order for kubectl to find and access a Kubernetes cluster, it needs a kubeconfig file, which is created automatically when you create a cluster using 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: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.The connection to the server <server-name:port> 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:kubectl cluster-info dump Troubleshooting the 'No Auth Provider Found' error messageIn Kubernetes 1.26, kubectl removed the built-in authentication for the following cloud providers' managed Kubernetes offerings. These providers have released kubectl plugins to provide the cloud-specific authentication. For instructions, refer to the following provider documentation:Azure AKS: kubelogin pluginGoogle Kubernetes Engine: gke-gcloud-auth-plugin(There could also be other reasons to see the same error message, unrelated to that change.)Optional kubectl configurations and pluginsEnable shell autocompletionkubectl provides autocompletion support for Bash, Zsh, Fish, and PowerShell which can save you a lot of typing.Below are the procedures to set up autocompletion for Bash, Fish, and Zsh.IntroductionThe 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 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). The following instructions assume that you use Bash 4.1+ (that is, any Bash version of 4.1 or newer).Upgrade BashThe instructions here assume you use Bash 4.1+. You can check your Bash's version by running:echo $BASH_VERSION If it is too old, you can install/upgrade it using Homebrew:brew install bash Reload your shell and verify that the desired version is being used:echo $BASH_VERSION $SHELL Homebrew usually installs it at /usr/local/bin/bash.Install bash-completionNote:As mentioned, these instructions assume you use Bash 4.1+, which means you will install bash-completion v2 (in contrast to Bash 3.2 and bash-completion v1, in which case kubectl completion won't work).You can test if you have bash-completion v2 already installed with type _init_completion. If not, you can install it with Homebrew:brew install bash-completion@2 As stated in the output of this command, add the following to your ~/.bash_profile file:brew_etc="$(brew --prefix)/etc" && [[ -r "${brew_etc}/profile.d/bash_completion.sh" ]] && . "${brew_etc}/profile.d/bash_completion.sh" Reload your shell and verify that bash-completion v2 is correctly installed with type _init_completion.Enable kubectl autocompletionYou 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 ~/.bash_profile file:echo 'source <(kubectl completion bash)' >>~/.bash_profile Add the completion script to the /usr/local/etc/bash_completion.d directory: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:echo 'alias k=kubectl' >>~/.bash_profile echo 'complete -o default -F __start_kubectl k' >>~/.bash_profile If you installed kubectl with Homebrew (as explained here), 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.In any case, after reloading your shell, kubectl completion should be working.Note:Autocomplete for Fish requires kubectl 1.23 or later.The kubectl completion script for Fish can be generated with the command kubectl completion fish. Sourcing the completion script in your shell enables kubectl autocompletion.To do so in all your shell sessions, add the following line to your ~/.config/fish/config.fish file:kubectl completion fish | source After reloading your shell, kubectl autocompletion should be working.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:source <(kubectl completion zsh) If you have an alias for kubectl, kubectl autocompletion will automatically work with it.After reloading your shell, kubectl autocompletion should be working.If you get an error like 2: command not found: compdef, then add the following to the beginning of your ~/.zshrc file:autoload -Uz compinit compinit Configure kubercSee kuberc for more information.Install kubectl convert pluginA plugin for Kubernetes command-line tool kubectl, which allows you to convert manifests between different API versions. This can be particularly helpful to migrate manifests to a non-deprecated api version with newer Kubernetes release.
