To illustrate the basic functionalities of Ansible, we are going to start by relaunching our Hello World application.

In the previous section, we saw how to create a stack using the web interface. As you would expect, it is also possible to launch a stack using the command-line interface.

Go into your EffectiveDevOpsTemplates folder where you previously generated the helloworld-cf-template-v2.template file and run the following command:

$ aws cloudformation create-stack 
      --capabilities CAPABILITY_IAM 
      --stack-name ansible 
      --template-body file://helloworld-cf-template-v2.template  
      --parameters ParameterKey=KeyPair,ParameterValue=EffectiveDevOpsAWS
{
    "StackId": "arn:aws:cloudformation:us-east-1:511912822958:stack/ansible/6c52ef30-32b6-11e6-a0f4-500c524294d2"
}  

Our instance will soon be ready. We can now bootstrap our environment by creating a workspace.
