| To run kubernetes locally on your laptop, you'll need to install: | |
| 1. [kubectl](#/kubectl) | |
| 2. [minikube](#/minikube) | |
| 3. [docker](#/docker) | |
| 4. [Optional tooling for advanced users](#/go) | |

| <h4>minikube troubleshooting</h4> | |
| <p>If your minikube environment does not boot correctly:</p> | |
| <ol> | |
| <li>Minikube requires an OS virtualization back-end</li> | |
| <li>Most OSes include some support for virtualization</li> | |
| <li>You can use the <a href="https://github.com/kubernetes/minikube#quickstart"><code>--vm-driver</code></a> flag to select a specific virt provider</li> | |
| </ol> | |
| <pre><code contenteditable>minikube start --vm-driver=virtualbox</code></pre> | |
| <p>Check the project <a href="https://github.com/kubernetes/minikube#requirements"><code>README</code></a> for more information about <a href="https://github.com/kubernetes/minikube#requirements">supported virtualization options</a></p> | |
