When i run the playbook getting an error.
Error! environment is undefined

Kindly advise how to pass the value to roles.

Want to pass the values to roles.

If I understand that corerct the error you are observing is usually because of the variable initialization difference between compile time and runtime.

According the error message

 roles:
  - "{{ environment }}"

would be resolved during compile time and before the prompting for the environment during runtime.

 vars_prompt:
  - name: environment
    prompt: "Enter the environment"
    private: no

  > Dynamically loads and executes a specified role as a task.

• What's the difference between include_ and import_?

This means you would need to change the way you are referencing the role or providing the name for it. See a
