Manual Installation

Installing Docker

First, update your system packages:

sudo apt update
sudo apt upgrade -y

Install required packages for Docker:

sudo apt install -y apt-transport-https ca-certificates curl software-properties-common

Add Docker’s official GPG key:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

Set up the Docker repository:

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

Update package lists again and install Docker:

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

Verify Docker installation:

sudo docker --version

Add your user to the Docker group to run Docker without sudo:

sudo usermod -aG docker $USER

Note: You’ll need to log out and log back in for this change to take effect.

Verify Docker is working correctly:

docker run hello-world

Installing Minikube

Install required packages for Minikube:

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

Download the latest Minikube binary:

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

Install Minikube:

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

Install kubectl:

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

Verify the installations:

minikube version
kubectl version --client

Starting Minikube

Start Minikube with Docker as the driver:

minikube start --driver=docker

Verify Minikube status:

minikube status

Enable the Kubernetes dashboard (optional):

minikube dashboard

Additional Tips

To stop Minikube when not in use:

minikube stop

To delete the Minikube cluster:

minikube delete

To set Docker as the default driver for Minikube:

minikube config set driver docker

Installation Scripts

To make the installation process easier, you can use the following shell scripts.

How to Use the Scripts

Save all four scripts to the same directory.

Make them executable:

chmod +x install-docker.sh install-minikube.sh minikube-utils.sh setup-all.sh

To perform a complete installation, run:
Terminal window
```
./setup-all.sh
```
After installation completes, log out and log back in for the Docker group changes to take effect.

To manage your Minikube cluster, use the utility script:

./minikube-utils.sh start     # Start Minikube
./minikube-utils.sh status    # Check status
./minikube-utils.sh dashboard # Open Kubernetes dashboard
./minikube-utils.sh help      # See all available commands

Script Descriptions

install-docker.sh - Automates the Docker installation process
install-minikube.sh - Installs Minikube and kubectl
minikube-utils.sh - Provides a convenient interface for managing your Minikube cluster
setup-all.sh - Master script that runs the installation scripts in sequence
