ansible-role-drupal-setup

This role sets up files and folders for a Drupal 8 site – with a folder structure analog to Capistrano.

The folder structure is the prerequiste for a deployment of the Drupal site with Ansible.

Rename this role to derheap.drupal-setup after cloning.

Folder structure

To enable deployments and configuration updates without affecting the running Drupal 8 site, a folder structure analog to Capistrano is used.

example.com/
├── current -> /srv/www/example.com/releases/20200214101735_master
├── releases
│   ├── 20200214095316_dummy
│   ├── 20200214095847_master
│   └── 20200214101735_master
└── shared
    └── sites
        └── default
            ├── files
            └── settings.php

The shared directory holds the data to be shared with all releases – mainly the sitedirectory. The site directory is later symlinked into the current release.

Permissions

All files are owned by the user in drupal_core_owner and by the group set in drupal_deploy_group. The files are writable by the group. All user who have the right to deploy must be in that group.

Only sites/default/files is writable by the the webserver. The group is set to drupal_server_group.

The Git repository is writable for all members in the group defined in drupal_deploy_group.

Settings.php

A settting.php file with the database connection is copied in place. The database itself is not created. If you want to use an newer or modified version of the settings.php you must provide one in the templates directory of your playbook. The template name is settings.php.j2.

Dummy release

The Ansible role sets up a dummy release with a HTML file in web, so you can test the webserver without deploying a Drupal site.

Prerequisites

• The user running the playbook should be in the sudo group.
• If you init a Git repository with this role, Git must be installed.

Role Variables

When possible, the role uses variable names that are also used by other roles (mostly from Geerlingguy) to setup the server and database.
