Add Workload as a nested stack

Open templates/master.template.yaml in an editor to inspect the contents of the file. You should have only 1 resource - VPCStack.

You will add a resource of Type ‘AWS::CloudFormation::Stack’ to create second nested cloudformation stack.

Close templates/master.template.yaml file and run the following command to add Workload Stack resource.

curl -s https://raw.githubusercontent.com/aws-quickstart/quickstart-workshop-labs/master/implementing/templates/webserver.master.template.yaml >>templates/master.template.yaml

Commit your changes.

git commit -a -m 'Add Workload as a nested stack'
