When you launch an EC2 instance, you can use the user-data to bootstrap a instance creation script.

We can use the following code to start a web server and echo out it’s instance id:

#!/bin/bash
yum update -y
yum install -y httpd
systemctl start httpd
systemctl enable httpd
echo "<h1>Hello World from $(hostname -f)</h1>" > /var/www/html/index.html

Steps to create a new bootstrapped instance

Step 1 – Launch a new instance

Login to your EC2 console and click Launch instances.

Select an Amazon Machine Image (AMI). We will select Amazon Linux 2.

Choose an instance type from the list. We will use a Free Tier Eligible t2.micro. Click Next.

Keep all the options as default and scroll to the bottom of the page. In the User Data textfield, enter the following code snippet:

#!/bin/bash
yum update -y
yum install -y httpd
systemctl start httpd
systemctl enable httpd
echo "<h1>Hello World from $(hostname -f)</h1>" > /var/www/html/index.html
