Day 38 Getting Started with AWS Basics☁

Introduction

Amazon Web Services (AWS) stands as a beacon in the realm of cloud computing, offering a vast array of services that empower businesses and individuals to build, deploy, and scale applications with ease. What makes AWS even more enticing is its Free Tier, which provides a playground for students and cloud enthusiasts to gain hands-on experience without incurring any costs. If you're eager to embark on a cloud journey, creating a free account is your first step toward unlocking a world of possibilities.

IAM: Securely Managing Access

One key component that makes AWS a trusted platform is the Identity and Access Management (IAM) service. IAM allows users to securely control access to various AWS resources, offering a robust solution for managing permissions. With IAM, administrators can centrally define and manage who can access specific resources, ensuring a secure and organized cloud environment.

IAM plays a crucial role in determining who is authenticated (signed in) and authorized (has permissions) to use AWS resources. Let's delve deeper into IAM and explore its capabilities.

Getting to Know IAM

IAM provides a fine-grained control mechanism, allowing users to create and manage AWS users and groups, and control their access to AWS resources. By defining IAM policies, administrators can specify the actions users or groups are allowed or denied, creating a secure environment tailored to the organization's needs.

Task 1: IAM User Creation and EC2 Access

Step 1: IAM User Creation

To kick things off, we'll create an IAM user with a username of our choice. Follow these steps:

1. Log in to your AWS Management Console.

2. Navigate to the IAM dashboard.

3. Click on "Users" and then "Add user."

4. Enter a username of your choice, e.g., "CloudMaster."

5. Select "Programmatic access" to generate an access key and "AWS Management Console access" for console access.

6. Proceed to set permissions.

   Step 2: Granting EC2 Access

7. In the user details page, attach the "AmazonEC2FullAccess" policy to the user.

8. Review and create the user.

Step 3: Launching a Linux Instance and Installing Jenkins and Docker

Now that we have our IAM user with EC2 access, let's leverage this to launch a Linux instance and install Jenkins and Docker using a single shell script.

#!/bin/bash

# Update and install necessary packages
sudo apt-get update -y
sudo apt-get install -y openjdk-8-jdk docker.io

# Install Jenkins
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'
sudo apt-get update -y
sudo apt-get install -y jenkins

# Start Jenkins and Docker services
sudo service jenkins start
sudo service docker start

Save this script, make it executable (chmod +x script.sh), and run it on your Linux instance launched through the IAM user.

Task 2: Building the DevOps Team of Avengers

Step 1: IAM Users for Avengers

Now, let's create three IAM users for our DevOps Avengers:

1. CaptainOps

2. IronDeployer

3. ThorReleaseMaster

Step 2: DevOps Group and IAM Policy

1. Navigate to the IAM dashboard.

2. Create a new group named "DevOpsAvengers."

3. Attach an IAM policy that grants permissions for DevOps activities like EC2, S3, and more.

Step 3: Adding Users to DevOps Group

1. Add CaptainOps, IronDeployer, and ThorReleaseMaster to the "DevOpsAvengers" group.

   Congratulations! You've successfully completed both tasks. You've not only mastered IAM by creating a user with specific access but also established a formidable DevOps team with tailored permissions. These skills are invaluable as you navigate the dynamic landscape of AWS and DevOps. Happy cloud computing!
