Jenkins +Terraform + AWS Automation

AWS Automation Using Terraform  

Terraform is an Infrastructure as Code (IaC) tool that allows users to automate the provisioning and management of AWS resources efficiently. It uses a declarative configuration language (HCL) to define infrastructure components such as EC2 instances, S3 buckets, VPCs, and more.  


Steps to Create AWS Config Rules Using Jenkins & Terraform 🚀  


1️⃣ Setup Jenkins on EC2

- Install Jenkins on your EC2 instance.  

- Install required plugins: Terraform, AWS CLI, and Pipeline.  

- Configure AWS credentials in Jenkins.


2️⃣ Write Terraform Code for AWS Config Rules 📜

Create a Terraform script (`config-rules.tf`) to define two AWS Config rules.  


provider "aws" {

  region = "us-east-1"

}


resource "aws_config_config_rule" "s3_public_read_prohibited" {

  name = "s3-public-read-prohibited"

  source {

    owner = "AWS"

    source_identifier = "S3_BUCKET_PUBLIC_READ_PROHIBITED"

  }

}


resource "aws_config_config_rule" "ec2_volume_inuse_check" {

  name = "ec2-volume-inuse-check"

  source {

    owner = "AWS"

    source_identifier = "EC2_VOLUME_INUSE_CHECK"

  }

}


3️⃣ Create a Jenkins Pipeline 🏗️

Write a Jenkinsfile to automate deployment:  


pipeline {

    agent any

    environment {

        AWS_ACCESS_KEY_ID = credentials('aws-access-key') 

        AWS_SECRET_ACCESS_KEY = credentials('aws-secret-key')

    }

    stages {

        stage('Checkout Code') {

            steps {

                git 'https://github.com/your-repo.git'

            }

        }

        stage('Terraform Init') {

            steps {

                sh 'terraform init'

            }

        }

        stage('Terraform Apply') {

            steps {

                sh 'terraform apply -auto-approve'

            }

        }

    }

}


4️⃣ Run Jenkins Pipeline 🏃

- Trigger the pipeline in Jenkins.  

- Terraform will create two AWS Config rules.  

- Verify in AWS Console under Config > Rules.  


🎯 Done! Now AWS will monitor S3 bucket permissions & EC2 volume usage automatically!

Machine learning in Python

Image
Python has become a cornerstone in the field of machine learning due to its simplicity, versatility, and extensive ecosystem of libraries and frameworks. Python's syntax is easy to understand, making it accessible for beginners while powerful enough for experts. Key libraries like NumPy, pandas, and SciPy provide robust tools for data manipulation and analysis, which are crucial in preparing datasets for machine learning tasks. Frameworks such as TensorFlow, PyTorch, and scikit-learn simplify the implementation of machine learning algorithms. TensorFlow and PyTorch are particularly popular for deep learning applications, offering extensive support for building and training neural networks. Scikit-learn is widely used for more traditional machine learning methods, providing a user-friendly interface for implementing a range of algorithms from regression to clustering. Moreover, Python’s integration with Jupyter Notebooks facilitates interactive coding, visualization, and documentati...

AWS: Custom Config Rule

Image
-- Explain Custom config with an example? -- Custom config rules in AWS Config allow you to define your own rules to evaluate the configuration settings of your AWS resources. These rules help ensure that your resources are compliant with your organization's requirements and best practices. A custom config rule is created using AWS Lambda functions that evaluate the resource configurations and return a compliance status. {   "ConfigRuleName": "Sumodh c Sabu",   "Description": "Checks if S3 buckets have server-side encryption enabled.",   "InputParameters": {},   "Scope": {     "ComplianceResourceTypes": [       "AWS::S3::Bucket"     ]   },   "Source": {     "Owner": "CUSTOM_LAMBDA",     "SourceIdentifier": <<arn name>>   } } -- In this example , the custom config rule is named "Sumodh c Sabu" and its purpose is to verify if S3 buckets have se...

AWS Automation: EC2 Instance

Image
In expanding usage of cloud computing, efficientive resource management is key to optimizing costs and ensuring smooth operations. Amazon Web Services offers more than 200 of services, including EC2 instances, which are fundamental to many cloud infrastructures. However, managing numerous EC2 instances manually can be cumbersome and prone to human error. This is where automation comes to the rescue, particularly with Python scripting, to automate the tagging process. Auto-tagging EC2 instances with essential metadata like owner information can greatly enhance visibility and accountability within a cloud environment. By automatically tagging instances with the owner's details, teams can easily identify responsible parties for each resource, aiding in troubleshooting, cost allocation, and compliance. Python, with its simplicity and versatility, is an excellent choice for implementing automation workflows in AWS. Leveraging AWS SDK for Python (Boto3) , developers can interact with AWS...
