📌 Introduction 📌
🔸 AWS EC2 (Elastic Compute Cloud) provides scalable compute capacity in the cloud.
🔸 Jenkins is an open-source automation server for continuous integration and continuous deployment.
📌 Benefits of EC2 for Jenkins 📌
🔸 Flexibility to choose instance types based on Jenkins workload.
🔸 Scalability ensures seamless performance as user demands grow.
🔸 EC2 offers various Amazon Machine Images (AMIs) tailored for Jenkins.
📌 Step-by-Step Deployment 📌
1. Launch EC2 Instance 🚀
🔹 Log in to AWS Management Console.
🔹 Choose appropriate AMI with Jenkins compatibility.
🔹 Select desired instance type based on Jenkins requirements.
🔹 Configure security groups to allow Jenkins communication.
🔹 Review and launch the instance.
2. Access EC2 Instance 🌐
🔹 Use SSH to connect to your EC2 instance.
🔹 Retrieve the public IP address or DNS name.
3. Install Jenkins 🛠️
🔹 Update package lists: sudo apt update.
🔹 Install Java Development Kit (JDK): sudo apt install default-jdk.
🔹 Add Jenkins repository:
```
wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add -
sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'
```
🔹 Install Jenkins:
```
sudo apt update
sudo apt install jenkins
```
🔹 Start Jenkins service: sudo systemctl start jenkins.
🔹 Enable Jenkins to start on boot: sudo systemctl enable jenkins.
4. Initial Jenkins Setup ⚙️
🔹 Access Jenkins on your browser using the instance's public IP/DNS and port 8080 so you need to go on Instance > Security > Select Security Group > Inbound Rule > Edit Inbound Rule > Add 8080 and then save.
🔹 Retrieve Jenkins initial admin password:
```
sudo cat /var/lib/jenkins/secrets/initialAdminPassword
```
🔹 Follow the setup wizard, installing suggested plugins.
5. Install Required Plugins 📦
🔹 From the Jenkins dashboard, navigate to "Manage Jenkins" > "Manage Plugins".
🔹 Install plugins for AWS integration, Git, etc., as per your project needs.
6. Configure Jenkins ⚙️
🔹 Set up Jenkins global configurations, including AWS credentials if necessary.
🔹 Create Jenkins jobs for your projects with build and deploy steps.
7. Utilize EC2 Scalability ⬆️
🔹 Configure Jenkins to spin up additional EC2 agents for parallel builds.
🔹 Leverage EC2 Auto Scaling for dynamic Jenkins agent allocation.
📌 Conclusion 📌
Setting up Jenkins on AWS EC2 empowers your CI/CD pipeline with scalability and efficiency. 🚀
