Nextcloud
Nextcloud is the most popular self-hosted collaboration solution for tens of millions of users at thousands of organizations across the globe.
Dependencies
This service requires the following other services:
- a Postgres database
- a Traefik reverse-proxy server
- a Redis data-store (optional), installation details below
Configuration
To enable this service, add the following configuration to your vars.yml file and re-run the installation process:
########################################################################
# #
# nextcloud #
# #
########################################################################
nextcloud_enabled: true
nextcloud_hostname: mash.example.com
nextcloud_path_prefix: /nextcloud
# Redis configuration, as described below
########################################################################
# #
# /nextcloud #
# #
########################################################################
In the example configuration above, we configure the service to be hosted at https://mash.example.com/nextcloud.
You can remove the nextcloud_path_prefix variable definition, to make it default to /, so that the service is served at https://mash.example.com/.
Redis
Redis can optionally be enabled to improve Nextcloud performance. It's dubious whether using using Redis helps much, so we recommend that you start without it, for a simpler deployment.
To learn more, read the Memory caching section of the Nextcloud documentation.
As described on the Redis documentation page, if you're hosting additional services which require Redis on the same server, you'd better go for installing a separate Redis instance for each service. See Creating a Redis instance dedicated to Nextcloud.
If you're only running Nextcloud on this server and don't need to use Redis for anything else, you can use a single Redis instance.
Regardless of the method of installing Redis, you may need to adjust your Nextcloud configuration file (e.g. /mash/nextcloud/data/config/config.php) to add this:
'memcache.distributed' => '\OC\Memcache\Redis',
'memcache.locking' => '\OC\Memcache\Redis',
'redis' => [
'host' => 'REDIS_HOSTNAME_HERE',
'port' => 6379,
],
Where REDIS_HOSTNAME_HERE is to be replaced with:
mash-nextcloud-redis, when Creating a Redis instance dedicated to Nextcloudmash-redis, when using a single Redis instance.
Using the shared Redis instance for Nextcloud
To install a single (non-dedicated) Redis instance (mash-redis) and hook Nextcloud to it, add the following additional configuration:
########################################################################
# #
# redis #
# #
########################################################################
redis_enabled: true
########################################################################
# #
# /redis #
# #
########################################################################
########################################################################
# #
# nextcloud #
# #
########################################################################
# Base configuration as shown above
# Point Nextcloud to the shared Redis instance
nextcloud_redis_hostname: "{{ redis_identifier }}"
# Make sure the Nextcloud service (mash-nextcloud.service) starts after the shared Redis service (mash-redis.service)
nextcloud_systemd_required_services_list_custom:
- "{{ redis_identifier }}.service"
# Make sure the Nextcloud container is connected to the container network of the shared Redis service (mash-redis)
nextcloud_container_additional_networks_custom:
- "{{ redis_identifier }}"
########################################################################
# #
# /nextcloud #
# #
########################################################################
This will create a mash-redis Redis instance on this host.
This is only recommended if you won't be installing other services which require Redis. Alternatively, go for Creating a Redis instance dedicated to Nextcloud.
Creating a Redis instance dedicated to Nextcloud
The following instructions are based on the Running multiple instances of the same service on the same host documentation.
Adjust your inventory/hosts file as described in Re-do your inventory to add supplementary hosts, adding a new supplementary host (e.g. if nextcloud.example.com is your main one, create nectcloud.example.com-deps).
Then, create a new vars.yml file for the
inventory/host_vars/nextcloud.example.com-deps/vars.yml:
---
########################################################################
# #
# Playbook #
# #
########################################################################
# Put a strong secret below, generated with `pwgen -s 64 1` or in another way
# Various other secrets will be derived from this secret automatically.
mash_playbook_generic_secret_key: ''
# Override service names and directory path prefixes
mash_playbook_service_identifier_prefix: 'mash-nextcloud-'
mash_playbook_service_base_directory_name_prefix: 'nextcloud-'
########################################################################
# #
# /Playbook #
# #
########################################################################
########################################################################
# #
# redis #
# #
########################################################################
redis_enabled: true
########################################################################
# #
# /redis #
# #
########################################################################
This will create a mash-nextcloud-redis instance on this host with its data in /mash/nextcloud-redis.
Then, adjust your main inventory host's variables file (inventory/host_vars/nextcloud.example.com/vars.yml) like this:
########################################################################
# #
# nextcloud #
# #
########################################################################
# Base configuration as shown above
# Point Nextcloud to its dedicated Redis instance
nextcloud_redis_hostname: mash-nextcloud-redis
# Make sure the Nextcloud service (mash-nextcloud.service) starts after its dedicated Redis service (mash-nextcloud-redis.service)
nextcloud_systemd_required_services_list_custom:
- "mash-nextcloud-redis.service"
# Make sure the Nextcloud container is connected to the container network of its dedicated Redis service (mash-nextcloud-redis)
nextcloud_container_additional_networks_custom:
- "mash-nextcloud-redis"
########################################################################
# #
# /nextcloud #
# #
########################################################################
Installation
If you've decided to install a dedicated Redis instance for Nextcloud, make sure to first do installation for the supplementary inventory host (e.g. nextcloud.example.com-deps), before running installation for the main one (e.g. nextcloud.example.com).
Usage
After installation, you should follow Nextcloud's setup wizard at the URL you've chosen.
You can choose any username/password for your account.
In Storage & database, you should choose PostgreSQL (changing the default SQLite choice), with the credentials you see after running just run-tags print-nextcloud-db-credentials
Once you've fully installed Nextcloud, you'd better adjust its default configuration (URL paths, trusted reverse-proxies, etc.) by running: just run-tags adjust-nextcloud-config
Recommended other services
Collabora Online
To integrate the Collabora Online office suite, first install it by following its dedicated documentation page.
Then add the following additional Nextcloud configuration:
nextcloud_collabora_app_wopi_url: "{{ collabora_online_url }}"
# By default, various private IPv4 networks are whitelited to connect to the WOPI API (document serving API).
# If your Collabora Online installation does not live on the same server as Nextcloud,
# you may need to adjust the list of networks.
# If necessary, redefined the `nextcloud_collabora_app_wopi_allowlist` environment variable here.
There's no need to re-run the playbook after adjusting your vars.yml file.
You should, however run: just run-tags install-nextcloud-app-collabora
This will install and configure the Office app for Nextcloud.
You should then be able to click any document (.doc, .odt, .pdf, etc.) in Nextcloud Files and it should automatically open a Collabora Online editor.
You can also create new documents via the "plus" button.
