My Project

By following these steps, you should have successfully set up Minikube with Docker, installed kubectl, and optionally configured Jenkins for CI/CD automation. This setup will allow you to deploy microservices applications on Kubernetes locally with minimal downtime using strategies like blue-green deployment.

Getting Started

Prerequisites

Tools Required

1. VM (Virtual Machine) - You need to create a Virtual Machine on your system to install and run Minikube.
2. Minikube - Tool for running Kubernetes clusters locally.
3. Docker - A containerization tool needed for Minikube's setup.
4. kubectl - Command line tool for interacting with Kubernetes clusters.
5. Jenkins - For automating deployment processes (optional, for CI/CD).
6. Linux (Red Hat/CentOS/Fedora) - Minikube works best on Linux operating systems.

---

Prerequisites

1. Create a VM:

   • Install a Virtual Machine platform like VirtualBox, VMware, or KVM.
   • Set up a Linux distribution (Red Hat 9.2 is suggested).

2. Install Docker:

   • Follow the installation guide for Docker based on your operating system:

     sudo dnf install docker -y
     sudo systemctl start docker
     sudo systemctl enable docker

   • Make sure the Docker daemon is running and that your user is added to the Docker group:

     sudo usermod -aG docker $USER
     newgrp docker

3. Install Minikube:

   • Download and install Minikube:

     curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
     sudo mv minikube-linux-amd64 /usr/local/bin/minikube
     sudo chmod +x /usr/local/bin/minikube

4. Install kubectl:

   • Install kubectl using dnf or download the binary manually:

     sudo dnf install kubectl -y

---

Installation Steps

1. Install Minikube:

   • Run the following command to start Minikube with the default driver (Docker in this case):

     minikube start --driver=docker

2. Verify Minikube Setup:

   • Check if Minikube is running:

     minikube status

3. Setting up Jenkins (Optional for CI/CD):

   • Pull the latest Jenkins Docker image:

     sudo docker pull jenkins/jenkins:lts

   • Run Jenkins in a Docker container:

     sudo docker run -d -p 8080:8080 -p 50000:50000 --name jenkins jenkins/jenkins:lts

   • Retrieve the Jenkins initial admin password:

     sudo docker exec -it jenkins cat /var/jenkins_home/secrets/initialAdminPassword

4. Access Jenkins:

   • Visit http://localhost:8080 in your browser and use the password retrieved above to unlock Jenkins.

5. Set up Kubernetes with Minikube:

   • Use kubectl to interact with the Kubernetes cluster created by Minikube:

     kubectl cluster-info

---

Additional Configuration (Optional)

1. Install Jenkins Plugins:

   • From the Jenkins dashboard, go to Manage Jenkins > Manage Plugins, and install necessary plugins such as:
     • Kubernetes Plugin
     • CloudBees Folder Plugin
     • Docker Pipeline Plugin
     • Git Plugin

2. **Configure CI/CD Pipeline

   • Set up your Jenkins pipeline for automating deployments to Kubernetes clusters using Jenkins and Docker.

Webhooks

To trigger Jenkins pipeline builds automatically on code changes, set up a webhook in your GitHub repository with the following URL:

http://your-jenkins-server/github-webhook/

Docker Setup

Docker Commands

To build and run your Docker image, follow these steps:

1. Build the Docker Image:

   docker build -t my-django-app .

2. Run a Container using the Built Image:

docker run -d -p 8000:8000 my-django-app

Replace 8000:8000 with the appropriate port mapping if your Django application uses a different port.

3. View Running Containers: docker ps

4. Push the Docker Image to a Registry (e.g., Docker Hub):

docker push username/my-django-app

Replace username with your Docker Hub username and my-django-app with the name you want to give to your Docker image.
