This role is meant to deploy and upgrade Nextcloud instances to Debian systems.

This role uses the Ansible module nextcloud_app for managing Nextcloud apps. There is a pull request to include the module into Ansible.

• The requested Nextcloud version is installed into {{ nextcloud_work_dir }}/nextcloud-{{ nextcloud_version }}.
• The symlink {{ nextcloud_work_dir }}/nextcloud-current points to the active Nextcloud installation.

The role takes care of installing and upgrading Nextcloud and its apps. It doesn't install or configure MariaDB/MySQL, mail or web service. The latter has to be done separately.

PHP dependencies required for Nextcloud are installed by that role.

Some modules used in this role are new to Ansible 2.2 and it's tested with Ansible 2.2, 2.3 and 2.4.

The following preliminaries need to be met:

• Ansible 2.2 or newer
• Debian target system with the following requirements:
  • MariaDB/MySQL server with admin permissions (may be remote)
  • Webserver (e.g. Apache2/Nginx) with basic PHP support
  • Mail server if Nextcloud instance shall send out mails (may be remote)
  • jmespath library needs to be installed on the host running the playbook (needed for the json_query filter). See requirements.txt
• The Nextcloud data directory needs to be located outside nextcloud_work_dir

• Integrate the role in your playbook:

- hosts: cloud.example.org
  roles:
    - nextcloud
  tags:
    - nextcloud

• Configure role variables in host_vars for the target system:

# Nextcloud settings

nextcloud_workdir: "/var/www/cloud.example.org/nextcloud"
nextcloud_data_dir: "/srv/nextcloud/data"
nextcloud_config:
  system:
    memcache.local: '\OC\Memcache\APCu'
    memcache.distributed: '\OC\Memcache\Redis'
    memcache.locking: '\OC\Memcache\Redis'
    redis:
      host: localhost
      port: 6379
    trusted_domains:
      - cloud.example.org
  apps:
    notify_push:
      base_endpoint: "https://cloud.example.org/push"
nextcloud_mysql_password: "******"
nextcloud_admin_password: "******"
nextcloud_notify_push: True

nextcloud_apps:
  - admin_audit
  - calendar
  - contacts

• Deploy Nextcloud to the target system:

  ansible-playbook site.yml -t nextcloud -l cloud.example.org --diff

• Configure the VirtualHost in your webserver. The following is an example snippet for a jinja2 Apache2 vhost template:

{% set nextcloud_webroot = nextcloud_workdir|d() + '/nextcloud-current' %}
	DocumentRoot {{ nextcloud_webroot }}
	<Directory {{ nextcloud_webroot }}>
		Options FollowSymlinks
		AllowOverride All

		<IfModule mod_dav.c>
			Dav off
		</IfModule>

		SetEnv HOME {{ nextcloud_webroot }}
		SetEnv HTTP_HOME {{ nextcloud_webroot }}
	</Directory>

    # Proxy rules for the Nextcloud notify_push daemon
    ProxyPass /push/ws ws:https://127.0.0.1:7867/ws
    ProxyPass /push/ http:https://127.0.0.1:7867/
    ProxyPassReverse /push/ http:https://127.0.0.1:7867/

To upgrade a Nextcloud instance, it's sufficient to bump the version in Role variable nextcloud_version and run the role again.

If you prefer to upgrade Nextcloud manually, you can configure the role to not perform any uprades by setting nextcloud_upgrade to False. Beware that you also have to set nextcloud_instance to something that doesn't contain nextcloud_version in this case:

nextcloud_upgrade: False
nextcloud_instance: "{{ nextcloud_workdir }}/nextcloud"

When nextcloud_notify_push is enabled, the Nextcloud notify_push daemon will be installed, configured and enabled.

Please beware that further configuration might be needed:

• Redis needs to be configured for caching.
• Configure your webserver as reverse proxy. See the upstream documentation for details.
• Set base_endpoint for the notify_push app accordingly:

  nextcloud_config:
  [...]
    apps:
      notify_push:
        base_endpoint: "https://cloud.example.org/push"
  

For developing and testing the role we use Github Actions, Molecule, and Vagrant. On the local environment you can easily test the role with

Run local tests with:

molecule test 

Requires Molecule, Vagrant and python-vagrant to be installed.
