Here's a step-by-step guide to set up Minikube on your Debian 12 system for a complete Kubernetes learning lab:

Prerequisites

1. System Requirements:

   • 2 CPUs or more
   • 2GB of free memory
   • 20GB of free disk space
   • Internet connection

2. Software Requirements:

   • Docker
   • Kubectl
   • Minikube

Step 1: Install Docker

1. Update your package list:

   sudo apt-get update
   

2. Install required packages:

   sudo apt-get install -y ca-certificates curl gnupg lsb-release
   

3. Add Docker’s official GPG key:

   sudo mkdir -p /etc/apt/keyrings
   curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
   

4. Set up the Docker repository:

   echo \
   "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
   $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
   

5. Install Docker Engine:

   sudo apt-get update
   sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
   

6. Start and enable Docker:

   sudo systemctl start docker
   sudo systemctl enable docker
   

7. Verify Docker installation:

   sudo docker run hello-world
   

Step 2: Install Kubectl

1. Download the latest release:

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

2. Make the kubectl binary executable:

   chmod +x kubectl
   

3. Move the binary to your PATH:

   sudo mv kubectl /usr/local/bin/
   

4. Verify the installation:

   kubectl version --client
   

Step 3: Install Minikube

1. Download the latest Minikube binary:

   curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
   

2. Install Minikube:

   sudo install minikube-linux-amd64 /usr/local/bin/minikube
   

3. Verify the installation:

   minikube version
   

Step 4: Start Minikube

1. Start Minikube with Docker driver:

   minikube start --driver=docker
   

2. Verify Minikube status:

   minikube status
   

Step 5: Basic Minikube Commands

• Check cluster info:

  kubectl cluster-info
  

• Deploy a sample application:

  kubectl create deployment hello-minikube --image=k8s.gcr.io/echoserver:1.4
  kubectl expose deployment hello-minikube --type=NodePort --port=8080
  minikube service hello-minikube --url
  

• Access Minikube Dashboard:

  minikube dashboard
  

Step 6: Stop and Delete Minikube

• Stop Minikube:

  minikube stop
  

• Delete Minikube:

  minikube delete
