My own minikube Cheat Sheet

    

minikube quickly sets up a local Kubernetes cluster on your local laptop.

:warning: If you need an OpenShift cluster, then you need to review my CodeReady Containers Cheat Sheet or my Minishift Cheat Sheet.

This cheat sheet includes the most common commands to install, deploy, administrate or operate your local Kubernetes using minikube.

Enjoy it !!! :cool: :sunglasses:

Download and Install

minikube binaries are available here.

Download the archive for your operating system and extract its contents, copy it to your preferred location, and add the minikube binary to your PATH environment variable.

This page includes the main steps to install minikube.

To check that your installation:

❯ minikube version
minikube version: v1.15.1
commit: 23f40a012abb52eff365ff99a709501a61ac5876

Resourcing

By default minikube defines very low resources (CPU, memory). You could check them as:

❯ minikube config view
- cpus: 4
- memory: 16384

To assign the number of CPU:

❯ minikube config set cpus 4

To assign the memory:

❯ minikube config set memory 16384

Start

To start the default, or active profile:

❯ minikube start

To start a profile:

❯ minikube start --profile myprofile

Endpoints and Credentials

You could get the Kubernetes console as:

❯ minikube dashboard

Using profiles

When you have to manage different configurations, applications or deployments, you could use different namespaces in the same minikube instance, or use different profiles.

A profile is an instance of the minikube VM along with all of its configuration and state. The profile feature allows you to create and manage these isolated instances of minikube.

Each profile is created with its own configuration (memory, CPU, disk size, add-ons, and so on) and is independent of other profiles.

The active profile is the profile against which all commands are executed, unless the global --profile flag is used.

To create a new profile:

❯ minikube start -p demo

To list the profiles available:

❯ minikube profile list
|----------|-----------|---------|----------------|------|---------|---------|
| Profile  | VM Driver | Runtime |       IP       | Port | Version | Status  |
|----------|-----------|---------|----------------|------|---------|---------|
| demo     | kvm2      | docker  |                | 8443 | v1.19.2 | Running |
| minikube | kvm2      | docker  | 192.168.39.213 | 8443 | v1.19.2 | Stopped |
|----------|-----------|---------|----------------|------|---------|---------|

To delete a profile:

❯ minikube delete -p demo

Addons

minikube allows you to extend the Kubernetes setup with an add-on mechanism.

minikube provides a set of built-in add-ons that offer some common Kubernetes customization to assist with development. To list the default add-ons, run:

❯ minikube addons list
