# InstallationSetup

> Learn how to install and configure Kustomize on your local machine covering prerequisites, installation steps, and verification for various operating systems.

Learn how to install and configure Kustomize on your local machine. This guide covers the prerequisites, installation steps, and verification process for Linux, macOS, and Windows.

## Prerequisites

<Callout icon="lightbulb" color="#1CB2FE">
  Before you begin, ensure you have the following:

  * A running Kubernetes cluster
  * `kubectl` installed and configured to communicate with your cluster
</Callout>

## Supported Platforms

Kustomize provides a single installation script that auto-detects your operating system and installs the appropriate binary.

| Operating System     | Installation Method                                                                                                |
| -------------------- | ------------------------------------------------------------------------------------------------------------------ |
| Linux                | `curl -s "https://raw.githubusercontent.com/kubernetes-sigs/kustomize/master/hack/install_kustomize.sh" \| bash`   |
| macOS                | `curl -s "https://raw.githubusercontent.com/kubernetes-sigs/kustomize/master/hack/install_kustomize.sh" \| bash`   |
| Windows (PowerShell) | `iwr -useb "https://raw.githubusercontent.com/kubernetes-sigs/kustomize/master/hack/install_kustomize.ps1" \| iex` |

## Install Kustomize

Run the official installation script:

```bash theme={null}
curl -s "https://raw.githubusercontent.com/kubernetes-sigs/kustomize/master/hack/install_kustomize.sh" | bash
```

This will download the latest Kustomize binary and place it in your current directory. To make it globally available, move it into your `PATH`:

```bash theme={null}
mv kustomize /usr/local/bin/
chmod +x /usr/local/bin/kustomize
```

## Verify the Installation

Check that Kustomize is installed correctly by running:

```bash theme={null}
kustomize version --short
```

Expected output:

```text theme={null}
{kustomize/v4.4.1 2021-11-11T23:36:27Z}
```

If you don’t see a version string:

1. Close and reopen your terminal to refresh `PATH`.
2. Rerun the installation script from above.

<Callout icon="triangle-alert" color="#FF6B6B">
  If the `kustomize` command is not found after installation, ensure `/usr/local/bin` (or your chosen install directory) is included in your `PATH` environment variable.
</Callout>
