# OpenCloud {#module-services-opencloud}

[OpenCloud](https://opencloud.eu/en) is an open-source, modern file-sync and
sharing platform. It is a fork of oCIS, a ground-up rewrite of the well-known
PHP-based NextCloud server.

The service can be configured using a combination of [](#opt-services.opencloud.settings),
[](#opt-services.opencloud.environment) and [](#opt-services.opencloud.environmentFile).

## Basic usage {#module-services-opencloud-basic-usage}

OpenCloud is configured using a combination of YAML and environment
variables. The full documentation can be found at
[OpenCloud Admin Docs](https://docs.opencloud.eu/docs/admin/intro).

The general flow of configuring OpenCloud is:
- configure services with `services.opencloud.settings.<service>` when possible
- configure global settings that affect multiple services via `services.opencloud.environment`
- allow NixOS to provision a default `opencloud.yaml` for you, containing default credentials
  for communication between the microservices
- provide additional secrets via `environmentFile`, provisioned out of band

Please note that current NixOS module for OpenCloud is configured to run in
`fullstack` mode, which starts all the services for OpenCloud in a single
instance, in so called supervised mode. This will start multiple OpenCloud
services and listen on multiple other ports.

Current known services and their ports are as below:
