What are CloudFormation outputs and how do I use them?

CloudFormation outputs are values that you can import into other stacks or view on the AWS Management Console. They help you share information between stacks.

Can you give me an example of how to define outputs in a CloudFormation template?

Sure! In a CloudFormation template, you can define outputs like this:

Outputs:
  MyOutput:
    Description: "The ID of the created EC2 instance"
    Value: !Ref MyEC2Instance

This will output the ID of the EC2 instance created in the stack.

How can I access these outputs after the stack is created?

You can access the outputs in the AWS Management Console under the CloudFormation stack details, or by using the AWS CLI with the command aws cloudformation describe-stacks.

Are there any limitations on the values I can output?

Yes, outputs can only include certain types of values, such as strings, and they cannot include sensitive information like passwords.
