Lambda-Deployment-with-CICD-Pipeline

Project Overview

This repository demonstrates a straightforward CI/CD setup for deploying an AWS Lambda function using Jenkins, Docker, and Amazon Elastic Container Registry (ECR). The project includes a basic Python Lambda function that prints "Hello, World!" when invoked. The CI/CD pipeline, orchestrated by Jenkins, utilizes Docker for containerized builds and ECR for efficient container image storage.

Prerequisites

Before you begin, ensure the following prerequisites are met:

• AWS account with appropriate permissions.
• AWS CLI installed.
• Docker installed.
• Jenkins installed.
• Git installed.

Setup

1. Lambda Execution Role:

   • In your AWS account, create a role for the Lambda function with the following permissions:
     • logs:CreateLogGroup
     • logs:CreateLogStream
     • logs:PutLogEvents
   • Alternatively, you can use the default Lambda execution role.

2. Jenkins AWS Credentials:

   • Install the AWS credentials extension in Jenkins.
   • Set up AWS credentials in Jenkins with the following details:
     • credentialsId: 'aws-credentials'
     • accessKeyVariable: 'AWS_ACCESS_KEY_ID'
     • secretKeyVariable: 'AWS_SECRET_ACCESS_KEY'

3. Clone Repository:

   • Clone the repository using the following commands:

     git clone https://github.com/harshartz/Lambda-Deployment-with-CICD-Pipeline.git
     cd Lambda-Deployment-with-CICD-Pipeline

4. Update Jenkinsfile:

   • Open the Jenkinsfile and make the following changes in the environment section:

     environment {
         AWS_REGION = 'ap-south-1'
         AWS_ACCOUNT_ID = '054774128594'
         ECR_REPO_NAME = 'go-digi-task2'
         IMAGE_NAME = 'helloworld-lambda'
         LAMBDA_FUNCTION_NAME = 'ecr-trigger'
         IAM_ROLE_ARN = 'arn:aws:iam::054774128594:role/go-digi-task'
     }

   • Change the values of the environment variables according to your AWS setup.

5. Run the Pipeline:

   • Trigger the Jenkins pipeline to build, push, and deploy the Docker image and Lambda function.

You are now ready to deploy the Lambda function using Jenkins and Docker.
