Build an appspec.yml

At NovaTech, you're setting up CodeDeploy for a Python web application on EC2. Use the appspec.yml builder to explore how the file is structured.

The builder lets you toggle sections on and off and see how the resulting appspec.yml changes. Experiment with different file mappings and lifecycle hooks to understand the relationship between the YAML structure and what CodeDeploy executes.
