# ownCloud Infinite Scale {#module-services-ocis}

[ownCloud Infinite Scale](https://owncloud.dev/ocis/) (oCIS) is an open-source,

modern file-sync and sharing platform. It is a ground-up rewrite of the well-known PHP based ownCloud server.

The server setup can be automated using

[services.ocis](#opt-services.ocis.enable). The desktop client is packaged at

`pkgs.owncloud-client`.

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

oCIS is a golang application and does not require an HTTP server (such as nginx)

in front of it, though you may optionally use one if you will.

oCIS is configured using a combination of yaml and environment variables. It is

recommended to familiarize yourself with upstream's available configuration

options and deployment instructions:

* [Getting Started](https://owncloud.dev/ocis/getting-started/)

* [Configuration](https://owncloud.dev/ocis/config/)

* [Basic Setup](https://owncloud.dev/ocis/deployment/basic-remote-setup/)

A very basic configuration may look like this:

```

{ pkgs, ... }:

{

  services.ocis = {

    enable = true;

    configDir = "/etc/ocis/config";

  };

}

```

This will start the oCIS server and make it available at `https://localhost:9200`

However to make this configuration work you will need generate a configuration.

You can do this with:

```console

$ nix-shell -p ocis-bin

$ mkdir scratch/

$ cd scratch/

$ ocis init --config-path . --admin-password "changeme"

```

You may need to pass `--insecure true` or provide the `OCIS_INSECURE = true;` to

[`services.ocis.environment`][mod-envFile], if TLS certificates are generated

and managed externally (e.g. if you are using oCIS behind reverse proxy).

If you want to manage the config file in your nix configuration, then it is

encouraged to use a secrets manager like sops-nix or agenix.

Be careful not to write files containing secrets to the globally readable nix

store.

Please note that current NixOS module for oCIS is configured to run in `fullstack`

mode, which starts all the services for owncloud on single instance. This will

start multiple ocis services and listen on multiple other ports.

Current known services and their ports are as below:

## Configuration via environment variables

You can also eschew the config file entirely and pass everything to oCIS via

environment variables. For this make use of

[`services.ocis.environment`][mod-env] for non-sensitive

values, and

[`services.ocis.environmentFile`][mod-envFile] for

sensitive values.

Configuration in (`services.ocis.environment`)[mod-env] overrides those from

[`services.ocis.environmentFile`][mod-envFile] and will have highest

precedence

[mod-env]: #opt-services.ocis.environment

[mod-envFile]: #opt-services.ocis.environmentFile

          Add `--insecure true` if SSL certificates are generated and managed externally (e.g. using oCIS behind reverse proxy).

          Note: This directory must contain at least a `ocis.yaml`. Ensure

          [user](#opt-services.ocis.user) has read/write access to it. In some
