What are AWS CloudFormation Outputs?

Can you explain what AWS CloudFormation Outputs are?

Sure! AWS CloudFormation Outputs are used to declare output values from your CloudFormation stacks. They can be useful for sharing information between stacks or for displaying important data after stack creation.

How do I define Outputs in my CloudFormation template?

You define Outputs in the 'Outputs' section of your CloudFormation template. Each output has a logical name, a value, and optionally, a description.

Can you give me an example of an Output in a template?

Absolutely! Here's a simple example:

Outputs:
  MyInstancePublicIP:
    Description: "Public IP of the newly created EC2 instance"
    Value: !GetAtt MyEC2Instance.PublicIp

This outputs the public IP of an EC2 instance.

What can I do with the Outputs after I create a stack?

After creating a stack, you can view the Outputs in the AWS Management Console, use them in other stacks, or reference them in scripts and applications.
