Jenkins AWS

Jenkins is a widely used open-source automation server that is commonly used for continuous integration and continuous delivery (CI/CD) pipelines. It helps developers automate the process of building, testing, and deploying software applications.

Amazon Web Services (AWS) is a cloud computing platform provided by Amazon. It offers various cloud services, including computing power, storage, databases, machine learning, networking, and more.

Jenkins can be deployed and utilized on AWS to create CI/CD pipelines for applications hosted on AWS infrastructure. Here’s a general outline of how you can set up Jenkins on AWS:

1. EC2 Instance: Start by creating an EC2 instance on AWS, which will be your Jenkins server. You can choose an appropriate instance type based on your requirements.

2. Security Groups: Configure security groups to allow access to the Jenkins server via SSH (port 22) for administration and HTTP/HTTPS (ports 80 and 443) for Jenkins web interface access.

3. Install Jenkins: Once your EC2 instance is up and running, connect to it via SSH and install Jenkins on the server using the package manager suitable for the operating system you’re using.

4. Configure Jenkins: After installation, access the Jenkins web interface using the public IP address or DNS of your EC2 instance. You will be prompted to set up Jenkins with an initial admin password that you can find on the server.

5. Install Plugins: Jenkins provides a vast number of plugins that extend its functionality. Depending on your needs, you may need to install plugins for integration with AWS services, version control systems (e.g., Git), testing frameworks, etc.

6. Create Jenkins Jobs: Set up your CI/CD pipelines by creating Jenkins jobs. These jobs define the steps involved in building, testing, and deploying your applications. You can define these jobs using the Jenkins web interface or by using a Jenkinsfile, which is a script that defines the pipeline as code.

7. Integrate with AWS Services: If your application uses AWS services, you can integrate Jenkins with them. For example, you might use AWS S3 for artifact storage, AWS CodeDeploy for deployment, AWS Lambda for serverless functions, or other services.

8. Configure Credentials: For secure integration with AWS services, you’ll need to configure credentials within Jenkins to access your AWS resources. Use Jenkins’ built-in credentials manager to store AWS access keys or IAM roles securely.

9. Trigger Pipelines: Jenkins jobs can be triggered manually or automatically. You might configure webhooks in your version control system to automatically trigger Jenkins jobs whenever new code is pushed.
