Day 81 - Project-2
Hi, I am Pooja Bhavani, an enthusiastic DevOps Engineer with a focus on deploying production-ready applications, infrastructure automation, cloud-native technologies. With hands-on experience across DevOps Tools and AWS Cloud, I thrive on making infrastructure scalable, secure, and efficient. My journey into DevOps has been fueled by curiosity and a passion for solving real-world challenges through automation, cloud architecture, and seamless deployments. I enjoy working on projects that push boundaries whether it's building resilient systems, optimizing CI/CD pipelines, or exploring emerging technologies like Amazon Q and GenAI. I'm currently diving deeper into platform engineering and GitOps workflows, and I often share practical tutorials, insights, and use cases from my projects and experiences. ✨ Let’s connect, collaborate, and grow together in this ever-evolving DevOps world. Open to opportunities, ideas, and conversations that drive impactful tech!
Deploying web app using Jenkins CI/CD declarative pipeline.
Follow the steps:
1. First of all, go to the AWS portal, and create a new instance. As
· Name: jenkins-server
· AMI: ubuntu.
· Instance type: t2.micro (free tier).
· Key pair login: Create > docker.pem.
· Allow HTTP.
· Allow HTTPS.
· (Download the .pem file.)
· Click on Launch Instance.
2. Now, we will allow ports 8080 and 8001 for this machine from a security group. We can find the security group in the VM description. Now, here we need to allow “Inbound Rule”
3. Now, connect to the EC2 instance that you have created. Copy the SSH from the server:
4. Go to the download folder, where the .pem file is placed and open the terminal in the same location, and paste the SSH.
5. Install Jenkins from the following link:
https://www.jenkins.io/doc/book/installing/linux/
6. Install Docker by running:
“Sudo apt-install docker.io”
7. Now check if it got installed by running “jenkins — version” and “docker — version”
8. Goto Jenkins Dashboard and Click on “New Item”
· Name: declarative_pipeline
· Select: Pipeline
Description: This is a demo pipeline project.
s Pipeline Script:
pipeline{
agent any
stages{
stage{
steps{
git branch: ‘main’, URL: ‘https://github.com/chxtan/react_django_demo_app.git'
}
}
stage{
steps{
echo “Testing”
}
}
stage{
steps{
script{
sh “docker build — no-cache -t react_django_demo_app .”
}
}
}
stage{
steps{
script{
sh “docker run -p 8001:8001 -d react_django_demo_app”
}
}
}
}
}
10. Click on “Save”.
11. Click on “Build Now”.
12. We can click on “Stage View” to check the results if it is still under process.
13. Once it will be completed, It will return as “Success”.
14. Now, Search for the Public IP with port 8001 in the browser,
We have built the image of a Web app source code, and deployed that image as a container, using Jenkins Pipelines.
