About this Hands-on Lab

This lab takes an in-depth look at CloudFormation template anatomy. Each section of a CloudFormation template will be covered in detail, and, ultimately, a CloudFormation template will be constructed piece by piece. After completing this lab, the student will have a deeper understanding of constructing CloudFormation templates in both JSON and YAML.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Create a CloudFormation Stack
  1. Navigate to CloudFormation.
  2. Click Create stack.
  3. In the new CloudFormation page, click Designer
  4. Click the Template tab at the bottom.
  5. Copy everything in the Template_Anatomy2.yaml file, and paste it into the Template window.
  6. In a new browser tab, navigate to EC2 > Key Pairs.
  7. Click Create Key Pair.
  8. Give it a key pair name of "tempanatomy", and click Create.
  9. Click Security Groups in the left-hand menu.
  10. Copy the security group ID and paste it into a text file, since we’ll need it in a minute.
  11. Navigate to VPC > Subnets.
  12. Select one of the listed subnets, and copy its subnet ID. Paste it into a text file, since we’ll also need it later.
  13. Back in the CloudFormation template window, click the checkbox at the top to validate the template, and then click the cloud icon with the up arrow to create the stack.
  14. Click Next.
  15. On the stack details page, set the following values:
    • Stack name: tempanatomyLab
    • InstanceType: t2.micro
    • KeyName: tempanatomy
    • MySG: Paste in the security group ID you copied earlier
    • MySubnet: Paste in the subnet ID you copied earlier
  16. Click Next.
  17. On the stack options page, set the Key as "name" and Value as "tempanatomy".
  18. Click Next.
  19. Click Create stack. It will take a few minutes for it to fully be created.
Delete a CloudFormation Stack
  1. Once the stack is created, click Delete at the top.
  2. In the confirmation dialog, click Delete stack.
