Day 38 - Embarking on the AWS Journey: A Beginner's Guide to Cloud Basics! 🚀☁️

🌟 Day 38 of #90DaysOfDevOpsChallenge! 🚀 Today, let's embark on a new journey with AWS Basics! ☁ Congratulations on how far you've come! Let's dive into the world of Amazon Web Services (AWS), one of the leading cloud providers. 💼🔍

🔑 Start by understanding AWS Identity and Access Management (IAM). IAM allows you to securely control access to AWS resources, manage permissions, and control user authentication. Learn more about IAM here: IAM Overview

Task 1️⃣: Creating an IAM User and Launching a Linux Instance

1. IAM User Creation:

   • Sign in to the AWS Management Console and navigate to IAM.

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

2. • Enter a username of your choice, select "Programmatic access", and click "Next: Permissions".

     • Choose "Attach existing policies directly" and select

• "AmazonEC2FullAccess". Click "Next: Tags" and then "Next: Review".

• Review the user details and click "Create user". Make sure to note down the access key and secret key. �

3. Launching a Linux Instance:

   

   

   • Navigate to the EC2 Dashboard and click "Launch instance".

• Choose an Amazon Machine Image (AMI) for your Linux instance.

• Configure the instance details, such as instance type, network settings, and IAM role. Select the IAM user created earlier.

• Add storage, tags, and configure security groups to allow SSH and HTTP(S) traffic.

• Review and launch the instance. Use the IAM user's access key and secret key to authenticate. 🚀

4. Installing Jenkins and Docker with a Shell Script:

   Installation of Jenkins

   • Jenkins requires Java in order to run. There are multiple Java implementations that you can use. OpenJDK is the most popular one.

   • Update the Debian apt repositories, install OpenJDK 17, and check the installation with the below commands:

           sudo apt update
           sudo apt install fontconfig openjdk-17-jre
           java -version
           openjdk version "17.0.8" 2023-07-18
           OpenJDK Runtime Environment (build 17.0.8+7-Debian-1deb12u1)
           OpenJDK 64-Bit Server VM (build 17.0.8+7-Debian-1deb12u1, mixed mode, sharing)
     

     Use the below command to install Jenkins from debian-stable apt repository:

           sudo wget -O /usr/share/keyrings/jenkins-keyring.asc \
             https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key
           echo "deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc]" \
             https://pkg.jenkins.io/debian-stable binary/ | sudo tee \
             /etc/apt/sources.list.d/jenkins.list > /dev/null
           sudo apt-get update
           sudo apt-get install jenkins
     

     Enter the below code to launch Docker

       sudo apt-get update
       sudo apt install docker.io
     

     Use the below command to check Jenkins and Docker is installed or not -

       -version
       docker --version
     

     Jenkins and Docker is installed successfully in the machine through IAM User.

Task 2️⃣: Building the DevOps Team of Avengers

1. Creating IAM Users for Avengers:

   • Follow the same steps as Task 1 to create three IAM users with unique usernames (e.g., ironman, thor, captainamerica).

   • Assign these users to appropriate IAM groups (e.g., DevOps) with custom IAM policies granting necessary permissions for DevOps tasks. 👥

2. Assigning IAM Policies to DevOps Groups:

   • Navigate to IAM and select "Groups".🛡️

   • Create a new group named "DevOps" and attach policies like "AmazonEC2FullAccess", "AmazonS3FullAccess", and "AmazonRDSFullAccess".

Feel free to adjust the steps according to your preferences and requirements. 🌟🚀Happy Learning! 📚✨ #AWS #DevOps #LearningJourney #CloudComputing ☁🔧
