DevOps Project-2

Project Description

The project is about automating the deployment process of a web application using Jenkins and its declarative syntax. The pipeline includes stages like building, testing, and deploying to a staging environment. It also includes running acceptance tests and deploying to production if all tests pass.

Steps:

Go to EC2 console and Create an EC2 instance.

Connect to the EC2 instance using SSH client

Step 2: Install jenkins and Docker on AWS EC2 Ubuntu instance.

Install Jenkins and Docker from my Devops Project 1 article

Install Jenkins:

Jenkins requires the Java Runtime Environment (JRE).

To install OpenJDK 11, run:

sudo apt install openjdk-11-jdk -y        

Follow below steps to install jenkins:

curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key | sudo tee 
  /usr/share/keyrings/jenkins-keyring.asc > /dev/null
echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] \
  https://pkg.jenkins.io/debian-stable binary/ | sudo tee \
  /etc/apt/sources.list.d/jenkins.list > /dev/null
sudo apt-get update
sudo apt-get install jenkins        

Install Docker:

Install docker using below command:

sudo apt-get install docker.io        

 Check version of Jenkins and docker using command:

jenkins --version
docker --version        

Browse instance-public-IP:8080 it will open jenkins dashboard.

Go to Jenkins Dashboard and Click on “New Item”

Give your project a name and select “Pipeline” as the project type.

Go to project configuration page

Now go to the pipeline session, In definition select Pipeline script

Write a pipeline script

Pipeline:

The Declarative pipeline should start with the pipeline block and this is the mandatory block.

Agent:

Agent signifies where the Jenkins build job should run. In this case, we have selected agent as any.

Stages:

stages block consists of different executable stage blocks.

At least one stage block is mandatory inside the stages block.

This pipeline has four stages:

1. Checkout: This stage checks out the code from the develop branch on GitHub.
2. Build: This stage builds a Docker image for the Django application.
3. Test: This stage runs unit tests for the Django application.
4. Deploy: This stage deploys the Docker container for the Django application.

Steps:

Steps blocks consist of the actual operation which needs to be performed inside Jenkins.

Build the project. You can manually build the project by clicking on the “Build Now” link in the project’s main page

Build is successfully completed.

After a build is completed, you can view the console output by clicking on the “Console Output” link in the build page.

You can see the each stage view by clicking on the “Full Stage View” in the project main page.

Docker image and container is created using jenkins pipeline.
