Minikube Installation (WSL Ubuntu)¶

This guide outlines the steps to install and configure Minikube on a Windows Subsystem for Linux (WSL) Ubuntu 20.04 LTS environment.^[400-devops-06-kubernetes-minikube-01-install.md]

Prerequisites¶

Before installing Minikube, it is recommended to update the system packages to their latest versions^[400-devops-06-kubernetes-minikube-01-install.md].

sudo apt update -y
sudo apt upgrade -y

sudo apt install -y curl wget apt-transport-https

Installation¶

The installation process involves downloading the latest Minikube binary and the kubectl command-line tool, then making them executable on your system^[400-devops-06-kubernetes-minikube-01-install.md].

1. Install Minikube¶

Download the Minikube binary, move it to your system path, and apply executable permissions^[400-devops-06-kubernetes-minikube-01-install.md].

wget https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo cp minikube-linux-amd64 /usr/local/bin/[Minikube](<./minikube.md>)
sudo chmod +x /usr/local/bin/[Minikube](<./minikube.md>)

Verify the installation by checking the version^[400-devops-06-kubernetes-minikube-01-install.md].

[Minikube](<./minikube.md>) version

2. Install kubectl¶

Download the specific version of kubectl that matches the latest stable Kubernetes release and install it^[400-devops-06-kubernetes-minikube-01-install.md].

curl -LO https://storage.googleapis.com/kubernetes-release/release/`curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/linux/amd64/kubectl
chmod +x [kubectl](<./kubectl.md>)
sudo mv [kubectl](<./kubectl.md>) /usr/local/bin/

You can verify the client version with the following command^[400-devops-06-kubernetes-minikube-01-install.md].

[kubectl](<./kubectl.md>) version -o yaml

Starting the Cluster¶

To start the cluster, you can use the minikube start command. While --driver=docker is an option, the Docker driver may be automatically selected if other drivers are not available^[400-devops-06-kubernetes-minikube-01-install.md].

[Minikube](<./minikube.md>) start --driver=docker

Recommended Start Flags¶

The following command provides a robust configuration for development, allocating specific resources and enabling necessary add-ons like the Ingress Controller and Flannel CNI^[400-devops-06-kubernetes-minikube-01-install.md].

[Minikube](<./minikube.md>) start --addons=ingress --cpus=2 --cni=flannel --install-addons=true --kubernetes-version=stable --memory=6g

• --addons=ingress: Enables the Ingress Controller for routing external traffic.
• --cpus=2: Allocates 2 CPUs.
• --cni=flannel: Sets the Container Network Interface to Flannel.
• --memory=6g: Allocates 6GB of RAM. Note: Ensure your cgroup configuration allows memory limits; otherwise, this may trigger a warning.

Verification¶

Once the cluster has started, you can verify its status and components^[400-devops-06-kubernetes-minikube-01-install.md].

Check the general Minikube status:

[Minikube](<./minikube.md>) status

Check cluster information:

[kubectl](<./kubectl.md>) cluster-info

List the available nodes:

[kubectl](<./kubectl.md>) get nodes

Managing Addons¶

Minikube includes various add-ons that can be enabled or disabled. You can view the current status of all available add-ons using the list command^[400-devops-06-kubernetes-minikube-01-install.md].

[Minikube](<./minikube.md>) addons list
