# Nextcloud
|
|
|
|
[Nextcloud](https://nextcloud.com/) 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](postgres.md) database
|
|
- a [Traefik](traefik.md) reverse-proxy server
|
|
- a [Redis](redis.md) data-store (optional), installation details [below](#redis)
|
|
|
|
|
|
## Configuration
|
|
|
|
To enable this service, add the following configuration to your `vars.yml` file and re-run the [installation](../installing.md) process:
|
|
|
|
```yaml
|
|
########################################################################
|
|
# #
|
|
# 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
|
|
|
|
As described on the [Redis](redis.md) 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](#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](#using-the-shared-redis-instance-for-nextcloud).
|
|
|
|
#### 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:
|
|
|
|
```yaml
|
|
########################################################################
|
|
# #
|
|
# 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).
|
|
|
|
#### 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](../running-multiple-instances.md) documentation.
|
|
|
|
Adjust your `inventory/hosts` file as described in [Re-do your inventory to add supplementary hosts](../running-multiple-instances.md#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`:
|
|
|
|
```yaml
|
|
---
|
|
|
|

|
|
# #
|
|
# 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_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:
|
|
|
|
```yaml
|
|
########################################################################
|
|
# #
|
|
# 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](../installing.md) 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](../installing.md), 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](collabora-online.md) office suite, first install it by following its dedicated documentation page.
|
|
|
|
Then add the following **additional** Nextcloud configuration:
|
|
|
|
```yaml
|
|
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](../installing.md) after adjusting your `vars.yml` file.
|
|
You should, however run: `just run-tags install-nextcloud-app-collabora`
|
|
|
|
This will install and configure the [Office](https://apps.nextcloud.com/apps/richdocuments) 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.
