# Roles
|
|
## Introduction
|
|
Roles in ansible are composed of multiples tasks that are executed together in order to configure a piece of software.
|
|
Usually, roles are included by playbooks.
|
|
The nice thing with roles is that they can be reused at different places, and thus it avoid copy/pasting of tasks.
|
|
Moreover, roles can take variables as input, so the tasks in the roles can do various things based on input parameters.
|
|
|
|
## Build your first role
|
|
In the previous lession, you built a playbook with tasks only.
|
|
Your job now will be to create 2 roles:
|
|
* one role for all tasks related to deploying the flask application
|
|
* one role for all tasks related to deploying nginx as a proxy
|
|
* for this one, you must also use some variables as input parameters for both ports (80 and 8080 in the previous lessons)
|

# Cleanup
|
|
Once you're done, destroy the demo docker:
|
|
|
|
```
|
|
docker stop demo
|
|
```
