Install Tools

Set up Kubernetes tools on your computer.

kubectl

The Kubernetes command-line tool, kubectl, allows you to run commands against Kubernetes clusters. You can use kubectl to deploy applications, inspect and manage cluster resources, and view logs. For more information including a complete list of kubectl operations, see the kubectl reference documentation.

kubectl is installable on a variety of Linux platforms, macOS and Windows. Find your preferred operating system below.

kind

kind lets you run Kubernetes on your local computer. This tool requires that you have either Docker or Podman installed.

The kind Quick Start page shows you what you need to do to get up and running with kind.

View kind Quick Start Guide

minikube

Like kind, minikube is a tool that lets you run Kubernetes locally. minikube runs an all-in-one or a multi-node local Kubernetes cluster on your personal computer (including Windows, macOS and Linux PCs) so that you can try out Kubernetes, or for daily development work.

You can follow the official Get Started! guide if your focus is on getting the tool installed.

View minikube Get Started! Guide

Once you have minikube working, you can use it to run a sample application.

kubeadm

You can use the kubeadm tool to create and manage Kubernetes clusters. It performs the actions necessary to get a minimum viable, secure cluster up and running in a user friendly way.

Installing kubeadm shows you how to install kubeadm. Once installed, you can use it to create a cluster.

1 - Install and Set Up kubectl on Linux

Before you begin

You must use a kubectl version that is within one minor version difference of your cluster. For example, a v1.32 client can communicate with v1.31, v1.32, and v1.33 control planes. Using the latest compatible version of kubectl helps avoid unforeseen issues.

Install kubectl on Linux

The following methods exist for installing kubectl on Linux:

Install kubectl binary with curl on Linux

  1. 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/linux/amd64/kubectl"
       

    
       curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/arm64/kubectl"
       
  2. 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/linux/amd64/kubectl.sha256"
       

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

    Validate the kubectl binary against the checksum file:

    echo "$(cat kubectl.sha256)  kubectl" | sha256sum --check
    

    If valid, the output is:

    kubectl: OK
    

    If the check fails, sha256 exits with nonzero status and prints output similar to:

    kubectl: FAILED
    sha256sum: WARNING: 1 computed checksum did NOT match
    
  3. Install kubectl

    sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl
    
  4. 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
    

Install using native package management

  1. Update the apt package index and install packages needed to use the Kubernetes apt repository:

    sudo apt-get update
    # apt-transport-https may be a dummy package; if so, you can skip that package
    sudo apt-get install -y apt-transport-https ca-certificates curl gnupg
    
  2. Download the public signing key for the Kubernetes package repositories. The same signing key is used for all repositories so you can disregard the version in the URL:

    # If the folder `/etc/apt/keyrings` does not exist, it should be created before the curl command, read the note below.
    # sudo mkdir -p -m 755 /etc/apt/keyrings
    curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.32/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg
    sudo chmod 644 /etc/apt/keyrings/kubernetes-apt-keyring.gpg # allow unprivileged APT programs to read this keyring
    
  1. Add the appropriate Kubernetes apt repository. If you want to use Kubernetes version different than v1.32, replace v1.32 with the desired minor version in the command below:

    # This overwrites any existing configuration in /etc/apt/sources.list.d/kubernetes.list
    echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.32/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list
    sudo chmod 644 /etc/apt/sources.list.d/kubernetes.list   # helps tools such as command-not-found to work correctly
    
  1. Update apt package index, then install kubectl:

    sudo apt-get update
    sudo apt-get install -y kubectl
    

  1. Add the Kubernetes yum repository. If you want to use Kubernetes version different than v1.32, replace v1.32 with the desired minor version in the command below.

    # This overwrites any existing configuration in /etc/yum.repos.d/kubernetes.repo
    cat <<EOF | sudo tee /etc/yum.repos.d/kubernetes.repo
    [kubernetes]
    name=Kubernetes
    baseurl=https://pkgs.k8s.io/core:/stable:/v1.32/rpm/
    enabled=1
    gpgcheck=1
    gpgkey=https://pkgs.k8s.io/core:/stable:/v1.32/rpm/repodata/repomd.xml.key
    EOF
    
  1. Install kubectl using yum:

    sudo yum install -y kubectl
    

  1. Add the Kubernetes zypper repository. If you want to use Kubernetes version different than v1.32, replace v1.32 with the desired minor version in the command below.

    # This overwrites any existing configuration in /etc/zypp/repos.d/kubernetes.repo
    cat <<EOF | sudo tee /etc/zypp/repos.d/kubernetes.repo
    [kubernetes]
    name=Kubernetes
    baseurl=https://pkgs.k8s.io/core:/stable:/v1.32/rpm/
    enabled=1
    gpgcheck=1
    gpgkey=https://pkgs.k8s.io/core:/stable:/v1.32/rpm/repodata/repomd.xml.key
    EOF
    
  1. Update zypper and confirm the new repo addition:

    sudo zypper update
    

    When this message appears, press 't' or 'a':

    New repository or package signing key received:

  2. Install kubectl using zypper:

    sudo zypper install -y kubectl
    

Install using other package management

If you are on Ubuntu or another Linux distribution that supports the snap package manager, kubectl is available as a snap application.

snap install kubectl --classic
kubectl version --client

If you are on Linux and using Homebrew package manager, kubectl is available for installation.

brew install kubectl
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:

(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 the command kubectl completion bash. Sourcing the completion script in your shell enables kubectl autocompletion.

However, the completion script depends on 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). 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:

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

Bash

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:


echo 'source <(kubectl completion bash)' >>~/.bashrc


kubectl completion bash | sudo tee /etc/bash_completion.d/kubectl > /dev/null
sudo chmod a+r /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' >>~/.bashrc
echo 'complete -o default -F __start_kubectl k' >>~/.bashrc

Both approaches are equivalent. After reloading your shell, kubectl autocompletion should be working. To enable bash autocompletion in current session of shell, source the ~/.bashrc file:

source ~/.bashrc

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

  1. 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/linux/amd64/kubectl-convert"
       

    
       curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/arm64/kubectl-convert"
       
  2. 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/linux/amd64/kubectl-convert.sha256"
       

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

    Validate the kubectl-convert binary against the checksum file:

    echo "$(cat kubectl-convert.sha256) kubectl-convert" | sha256sum --check
    

    If valid, the output is:

    kubectl-convert: OK
    

    If the check fails, sha256 exits with nonzero status and prints output similar to:

    kubectl-convert: FAILED
    sha256sum: WARNING: 1 computed checksum did NOT match
    
  3. Install kubectl-convert

    sudo install -o root -g root -m 0755 kubectl-convert /usr/local/bin/kubectl-convert
    
  4. Verify plugin is successfully installed

    kubectl convert --help
    

    If you do not see an error, it means the plugin is successfully installed.

  5. After installing the plugin, clean up the installation files:

    rm kubectl-convert kubectl-convert.sha256

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.

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

       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
    
  3. Make kubectl-convert binary executable

    chmod +x ./kubectl-convert
    
  4. 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
    
  5. Verify plugin is successfully installed

    kubectl convert --help
    

    If you do not see an error, it means the plugin is successfully installed.

  6. 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

  1. Locate the kubectl binary on your system:

    which kubectl
    
  2. 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

3 - Install and Set Up kubectl on Windows

Before you begin

You must use a kubectl version that is within one minor version difference of your cluster. For example, a v1.32 client can communicate with v1.31, v1.32, and v1.33 control planes. Using the latest compatible version of kubectl helps avoid unforeseen issues.

Install kubectl on Windows

The following methods exist for installing kubectl on Windows:

Install kubectl binary on Windows (via direct download or curl)

  1. You have two options for installing kubectl on your Windows device

    • Direct download:

      Download the latest 1.32 patch release binary directly for your specific architecture by visiting the Kubernetes release page. Be sure to select the correct binary for your architecture (e.g., amd64, arm64, etc.).

    • Using curl:

      If you have curl installed, use this command:

      curl.exe -LO "https://dl.k8s.io/release/v1.32.0/bin/windows/amd64/kubectl.exe"
      
  2. Validate the binary (optional)

    Download the kubectl checksum file:

    curl.exe -LO "https://dl.k8s.io/v1.32.0/bin/windows/amd64/kubectl.exe.sha256"
    

    Validate the kubectl binary against the checksum file:

    • Using Command Prompt to manually compare CertUtil's output to the checksum file downloaded:

      CertUtil -hashfile kubectl.exe SHA256
      type kubectl.exe.sha256
      
    • Using PowerShell to automate the verification using the -eq operator to get a True or False result:

       $(Get-FileHash -Algorithm SHA256 .\kubectl.exe).Hash -eq $(Get-Content .\kubectl.exe.sha256)
      
  3. Append or prepend the kubectl binary folder to your PATH environment variable.

  4. Test to ensure the version of kubectl is the same as downloaded:

    kubectl version --client
    

    Or use this for detailed view of version:

    kubectl version --client --output=yaml
    

Install on Windows using Chocolatey, Scoop, or winget

  1. To install kubectl on Windows you can use either Chocolatey package manager, Scoop command-line installer, or winget package manager.

    choco install kubernetes-cli
    

    scoop install kubectl
    

    winget install -e --id Kubernetes.kubectl
    
  2. Test to ensure the version you installed is up-to-date:

    kubectl version --client
    
  3. Navigate to your home directory:

    # If you're using cmd.exe, run: cd %USERPROFILE%
    cd ~
    
  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
    

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:

(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 PowerShell.

The kubectl completion script for PowerShell can be generated with the command kubectl completion powershell.

To do so in all your shell sessions, add the following line to your $PROFILE file:

kubectl completion powershell | Out-String | Invoke-Expression

This command will regenerate the auto-completion script on every PowerShell start up. You can also add the generated script directly to your $PROFILE file.

To add the generated script to your $PROFILE file, run the following line in your powershell prompt:

kubectl completion powershell >> $PROFILE

After reloading your shell, kubectl autocompletion should be working.

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

  1. Download the latest release with the command:

    curl.exe -LO "https://dl.k8s.io/release/v1.32.0/bin/windows/amd64/kubectl-convert.exe"
    
  2. Validate the binary (optional).

    Download the kubectl-convert checksum file:

    curl.exe -LO "https://dl.k8s.io/v1.32.0/bin/windows/amd64/kubectl-convert.exe.sha256"
    

    Validate the kubectl-convert binary against the checksum file:

    • Using Command Prompt to manually compare CertUtil's output to the checksum file downloaded:

      CertUtil -hashfile kubectl-convert.exe SHA256
      type kubectl-convert.exe.sha256
      
    • Using PowerShell to automate the verification using the -eq operator to get a True or False result:

      $($(CertUtil -hashfile .\kubectl-convert.exe SHA256)[1] -replace " ", "") -eq $(type .\kubectl-convert.exe.sha256)
      
  3. Append or prepend the kubectl-convert binary folder to your PATH environment variable.

  4. Verify the plugin is successfully installed.

    kubectl convert --help
    

    If you do not see an error, it means the plugin is successfully installed.

  5. After installing the plugin, clean up the installation files:

    del kubectl-convert.exe
    del kubectl-convert.exe.sha256
