task_definitions.rb file has access to helper methods. These helper methods provide useful contextual information about the project.

This is useful if someone changes the exported port in the Dockerfile, he will likely forget also to update the ufo variable. You can reference the port via the helper to prevent this from happening.

|env_file(path)||This method takes a
|secrets_vars(text)||This method takes a block of text that contains the secrets values in
