Day 40: AWS EC2 Automation ?

Welcome to Day 40 of our #90DaysofDevOps journey! Today, we're diving into automating tasks in AWS EC2 to make your cloud experience more efficient and streamlined.

AWS EC2

Amazon Elastic Compute Cloud (EC2) offers secure, reliable, high-performance, and cost-effective computing infrastructure to meet demanding business needs. By leveraging automation, you can further optimize your use of EC2.

Launch Template in AWS EC2

Launch templates allow you to save configuration details like AMI ID, instance type, and network settings, so you don't have to re-enter them each time you launch a new instance. This makes the process more efficient and less prone to errors. Read more about launch templates.

Instance Types

Amazon EC2 offers a variety of instance types optimized for different use cases. These types vary by CPU, memory, storage, and networking capacity, allowing you to select the right combination of resources for your applications. Learn more about instance types.

AMI

An Amazon Machine Image (AMI) is a pre-configured template that contains the information needed to launch an instance. AMIs help ensure that multiple instances can be launched with the same configuration. Read more about AMIs.

Tasks:

Task 1: Create a Launch Template

1. Create a Launch Template:Use the Amazon Linux 2 AMI.Select the t2.micro instance type.Include a User Data script to install Jenkins and Docker (refer to the Day 39 User Data script):sh

#!/bin/bash
# Update the package repository
sudo yum update -y

# Install Java (required for Jenkins)
sudo amazon-linux-extras install java-openjdk11 -y

# Install Jenkins
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins-ci.org/redhat/jenkins.repo
sudo rpm --import https://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key
sudo yum install jenkins -y
sudo systemctl start jenkins
sudo systemctl enable jenkins

# Install Docker
sudo amazon-linux-extras install docker -y
sudo service docker start
sudo usermod -aG docker ec2-user
sudo systemctl enable docker

echo "Jenkins and Docker installed successfully!"
        

1. Launch Instances Using the Template:Create three instances using the launch template.Look for the option to specify the number of instances to launch.

Task 2: Optional - Create an Auto-Scaling Group

• Create an Auto-Scaling Group based on the launch template to automatically manage the number of instances based on demand. Read more about Auto-Scaling Groups.
