Web
The web service embeds and serves the static files for the Infinite Scale Web Client.
Note that clients will respond with a connection error if the web service is not available.
The web service also provides a minimal API for branding functionality like changing the logo shown.
Custom Compiled Web Assets
If you want to use your custom compiled web client assets instead of the embedded ones, then you can do that by setting the WEB_ASSET_PATH variable to point to your compiled files. See ownCloud Web / Getting Started and ownCloud Web / Setup with oCIS for more details.
Web UI Configuration
Note that single configuration settings of the embedded web UI can be defined via WEB_OPTION_xxx environment variables. If a json based configuration file is used via the WEB_UI_CONFIG_FILE environment variable, these configurations take precedence over single options set.
Web UI Options
Beside theming, the behavior of the web UI can be configured via options. See the environment variables WEB_OPTION_xxx for more details.
Web UI Config File
When defined via the WEB_UI_CONFIG_FILE environment variable, the configuration of the web UI can be made with a json based file.
