Introduction

The frontend service translates various ownCloud related HTTP APIs to CS3 requests.

Default Values

Frontend listens on port 9140 by default.

Endpoints Overview

Currently, the frontend service handles requests for three functionalities, which are

appprovider,
archiver,
datagateway and
ocs.

appprovider

The appprovider endpoint, by default /app, forwards HTTP requests to the CS3 App Registry API.

archiver

The archiver endpoint, by default /archiver, implements zip and tar download for collections of files. It will internally use the CS3 API to initiate downloads and then stream the individual files as part of a compressed file.

datagateway

The datagateway endpoint, by default /data, forwards file up- and download requests to the correct CS3 data provider. OCIS starts a dataprovider as part of the storage-* services. The routing happens based on the JWT that was created by a storage provider in response to an InitiateFileDownload or InitiateFileUpload request.

ocs

The ocs endpoint, by default /ocs, implements the ownCloud 10 Open Collaboration Services API by translating it into CS3 API requests. It can handle users, groups, capabilities and also implements the file sharing functionality on top of CS3. The /ocs/v[12].php/cloud/user/signing-key is currently handled by the dedicated ocs service.

Scalability

While the frontend service does not persist any data, it does cache Stat() responses and user information. Therefore, multiple instances of this service can be spawned in a bigger deployment like when using container orchestration with Kubernetes, when configuring FRONTEND_OCS_RESOURCE_INFO_CACHE_TYPE=redis and the related config options.

Configuration

Environment Variables

The frontend service is configured via the following environment variables:
