Installation for production
###########################

An installation use these services, which are deployed using docker containers:

* a php-fpm image, which run the Php and Symfony code for Chill;
* a nginx image, which serves the assets, and usually proxy the php requests to the fpm image;
* a redis server, which stores the cache, sessions (this is currently hardcoded in the php image), and some useful keys (like wopi locks);
* a postgresql database. The use of postgresql is mandatory;
* a relatorio service, which transform odt templates to full documents (replacing the placeholders);

Some external services:

* (required) an openstack object store, configured with `temporary url <https://docs.openstack.org/swift/latest/api/temporary_url_middleware.html>` configured (no openstack users is required). This is currently the only way to store documents from chill;
* a mailer service (SMTP)
* (optional) a service for verifying phone number. Currently, only Twilio is possible;
* (optional) a service for sending Short Messages (SMS). Currently, only Ovh is possible;

The `docker-compose.yaml` file of chill app is a basis for a production install. The environment variable in the ```.env``` and ```.env.prod``` should be overriden by environment variables, or ```.env.local``` files.

This should be adapted to your needs:

* The image for php and nginx apps are pre-compiled images, with the default configuration and bundle. If they do not fullfill your needs, you should compile your own images.

   .. TODO:

      As the time of writing (2022-07-03) those images are not published yet.

* Think about how you will backup your database. Some adminsys find easier to store database outside of docker, which might be easier to administrate or replicate.

Cron jobs
=========

The command :code:`chill:cron-job:execute` should be executed every 15 minutes (more or less).

This command should never be executed concurrently. It should be not have more than one process for a single instance.

Post-install tasks
