Lab 01 | Introductory Example

We're going to create a simple EC2 instance.
Then we're going to create to add an Elastic IP to it
And we're going to add two security groups to it

Implementation

AWS CloudFormation Template reference (opens in a new tab)

Create a YAML file.

L01_1-simple_ec2.yaml

Resources:
  MyInstance:
    Type: AWS::EC2::Instance
    Properties:
      AvailabilityZone: us-east-1a
      ImageId: ami-a4c7edb2
      InstanceType: t2.micro
