A WSGI server like [[https://gunicorn.org/][Gunicorn]] can then be used to serve the app for example like this:
: $ gunicorn "raincloud:create_app(base_path='public')"
*Note* that currently only one worker makes sense due to server side session caching.
: $ gunicorn "raincloud:create_app(base_path='public', secret_key='i_am_a_key', redis_url='redis://127.0.0.1:6379/0')"

** Configuration
/raincloud/ provides two configuration options which can be passed to =raincloud.create_app()=:
/raincloud/ provides four configuration options which can be passed to =raincloud.create_app()=:
- =base_path= :: Base path of the raincloud
- =secret_key= :: Flask secret key
- =redis_url= :: URL of redis database (default: =redis://127.0.0.1:6379/0=)
- =cloud_name= :: Cloud name (default: =raincloud=)
Set them for example like this:
: >>> app = raincloud.create_app(base_path='/home/alice/public', cloud_name='myCloud')
: >>> app = raincloud.create_app(base_path='/home/alice/public', secret_key='i_am_a_key', redis_url='redis://127.0.0.1:6379/0', cloud_name='raincloud')
