Launch templates in AWS - Mini Project: Build & Apply

Create and Configure an AWS Launch Template

📖 Scenario: You are setting up a cloud environment where you want to launch virtual machines (EC2 instances) with consistent settings. To do this efficiently, you will create an AWS Launch Template that stores the configuration for these instances.

🎯 Goal: Build an AWS Launch Template that defines the instance type, Amazon Machine Image (AMI), and key pair for secure access. This template will help you launch EC2 instances with the same settings easily.

📋 What You'll Learn

Create a launch template named MyLaunchTemplate

Set the AMI ID to ami-0abcdef1234567890

Set the instance type to t3.micro

Specify the key pair name as MyKeyPair

💡 Why This Matters

🌍 Real World

Launch templates help cloud engineers quickly and consistently launch virtual machines with predefined settings, saving time and reducing errors.

💼 Career

Understanding launch templates is essential for roles like cloud engineer, DevOps engineer, and system administrator working with AWS infrastructure.

1

Create the basic launch template data structure

Create a dictionary called launch_template_data with keys ImageId set to "ami-0abcdef1234567890" and InstanceType set to "t3.micro".

AWS

# Your code here

Need a hint?

Think of launch_template_data as a box holding your instance settings like the image and size.

2

Add the key pair configuration

Add a key KeyName with value "MyKeyPair" to the existing launch_template_data dictionary.

AWS

launch_template_data = {
    "ImageId": "ami-0abcdef1234567890",
    "InstanceType": "t3.micro"
}
# Add the key pair name below

Need a hint?

The key pair lets you securely connect to your instance. Add it as another setting in the dictionary.

3

Create the launch template request dictionary

Create a dictionary called launch_template_request with keys LaunchTemplateName set to "MyLaunchTemplate" and LaunchTemplateData set to the launch_template_data dictionary.

AWS

launch_template_data = {
    "ImageId": "ami-0abcdef1234567890",
    "InstanceType": "t3.micro",
    "KeyName": "MyKeyPair"
}
# Create launch_template_request dictionary below

Need a hint?

This dictionary groups the template name and its data together, ready to be sent to AWS.

4

Add the version description to the launch template data

Add a key VersionDescription with value "Initial version" to the launch_template_data dictionary inside launch_template_request.

AWS

launch_template_data = {
    "ImageId": "ami-0abcdef1234567890",
    "InstanceType": "t3.micro",
    "KeyName": "MyKeyPair"
}

launch_template_request = {
    "LaunchTemplateName": "MyLaunchTemplate",
    "LaunchTemplateData": launch_template_data
}
# Add VersionDescription to launch_template_data below

Need a hint?

The version description helps you track changes to your launch template over time.
