Install and Set Up kubectl on macOS

Before you begin

You must use a kubectl version that is within one minor version difference of your cluster. For example, a v1.29 client can communicate with v1.28, v1.29, and v1.30 control planes. Using the latest compatible version of kubectl helps avoid unforeseen issues.

Install kubectl on macOS

The following methods exist for installing kubectl on macOS:

Install kubectl on macOS
Verify kubectl configuration
Optional kubectl configurations and plugins
- Enable shell autocompletion
- Install kubectl convert plugin

Install kubectl binary with curl on macOS

Download the latest release:

Intel
Apple Silicon


   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 1.29.3 on Intel macOS, type:

curl -LO "https://dl.k8s.io/release/v1.29.3/bin/darwin/amd64/kubectl"

And for macOS on Apple Silicon, type:

curl -LO "https://dl.k8s.io/release/v1.29.3/bin/darwin/arm64/kubectl"

Validate the binary (optional)

Download the kubectl checksum file:

Intel
Apple Silicon


   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 macOS

If you are on macOS and using Homebrew package manager, you can install kubectl with Homebrew.

Run the installation command:

brew install kubectl

brew install kubernetes-cli

Test to ensure the version you installed is up-to-date:
```
kubectl version --client
```

Install with Macports on macOS

If 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 configuration

In 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 message

In 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 plugin
Google 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 plugins

Enable shell autocompletion

kubectl 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.

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 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 Bash

The 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-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).

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 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 ~/.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

Install `kubectl convert` plugin

A 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. For more info, visit migrate to non deprecated apis

Download the latest release with the command:

Intel
Apple Silicon


   curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/darwin/amd64/kubectl-convert"


   curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/darwin/arm64/kubectl-convert"

Validate the binary (optional)

Download the kubectl-convert checksum file:

Intel
Apple Silicon


   curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/darwin/amd64/kubectl-convert.sha256"


   curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/darwin/arm64/kubectl-convert.sha256"

Validate the kubectl-convert binary against the checksum file:

echo "$(cat kubectl-convert.sha256)  kubectl-convert" | shasum -a 256 --check

If valid, the output is:

kubectl-convert: OK

If the check fails, shasum exits with nonzero status and prints output similar to:

kubectl-convert: FAILED
shasum: WARNING: 1 computed checksum did NOT match

Note: Download the same version of the binary and checksum.

Make kubectl-convert binary executable
```
chmod +x ./kubectl-convert
```
Move the kubectl-convert binary to a file location on your system PATH.
```
sudo mv ./kubectl-convert /usr/local/bin/kubectl-convert
sudo chown root: /usr/local/bin/kubectl-convert
```
Note: Make sure /usr/local/bin is in your PATH environment variable.
Verify plugin is successfully installed
```
kubectl convert --help
```
If you do not see an error, it means the plugin is successfully installed.
After installing the plugin, clean up the installation files:
```
rm kubectl-convert kubectl-convert.sha256
```

Uninstall kubectl on macOS

Depending on how you installed kubectl, use one of the following methods.

Uninstall kubectl using the command-line

Locate the kubectl binary on your system:
```
which kubectl
```
Remove the kubectl binary:
```
sudo rm <path>
```
Replace <path> with the path to the kubectl binary from the previous step. For example, sudo rm /usr/local/bin/kubectl.

Uninstall kubectl using homebrew

If you installed kubectl using Homebrew, run the following command:

brew remove kubectl
