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 binary with curl on macOS
-
Download 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
$(curl -L -s https://dl.k8s.io/release/stable.txt)
portion of the command with the specific version.For example, to download version 1.29.0 on Intel macOS, type:
curl -LO "https://dl.k8s.io/release/v1.29.0/bin/darwin/amd64/kubectl"
And for macOS on Apple Silicon, type:
curl -LO "https://dl.k8s.io/release/v1.29.0/bin/darwin/arm64/kubectl"
-
Validate the binary (optional)
Download the kubectl checksum file:
curl -LO "https://dl.k8s.io/release/$(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 macOS
If you are on macOS and using Homebrew package manager, you can install kubectl with Homebrew.
-
Run the installation command:
brew install kubectl
or
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.
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 $SHELL
Homebrew usually installs it at /usr/local/bin/bash
.
Install bash-completion
You can test if you have bash-completion v2 already installed with type _init_completion
.
If not, you can install it with Homebrew:
brew install bash-completion@2
As stated in the output of this command, add the following to your ~/.bash_profile
file:
brew_etc="$(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 theBASH_COMPLETION_COMPAT_DIR
directory, that's why the latter two methods work.
In any case, after reloading your shell, kubectl completion should be working.
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.

Download the latest release with the command:
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:
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 thekubectl
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
