In the docker setup, allow admin to provide the default values for
WebDAV settings in the "Sync" section of the "Settings" page, via
setting some environment variables of the docker container. This could
be used for single user instances to pre-fill those settings. The
available environment variables are:
- WEBDAV_BASE_URL=<base-url>
- WEBDAV_USERNAME=<username>
- WEBDAV_SYNC_FOLDER_PATH=<sync-folder-path>
- SYNC_INTERVAL=<integer-in-minutes>
- IS_COMPRESSION_ENABLED=<true-or-false>
- IS_ENCRYPTION_ENABLED=<true-or-false>
These configurations are provided as environment variables after the
build process of the app, so they have to be loaded at runtime, instead
of build process. This can be achieved by the following way:
1. The environment variables are loaded into the docker container.
2. The container starts with `docker-entrypoint.sh`.
3. `docker-entrypoint.sh` converts the variables into a JSON file placed
at `assets/sync-config-default-override.json`.
4. `sync-config.service.ts` fetches
`assets/sync-config-default-override.json` dynamically at runtime to
override the default values from `default-global-config.const.ts`.
This patch provides an optional way to integrate an external WebDAV server so that the super-productivity container can serve as a WebDAV server with base url http://localhost/webdav/ . It includes the following changes:
**Replace the default nginx config file**
Besides serving the web app, the new nginx config file also forwards all the requests with paths starting with "/webdav/" to a backend WebDAV server specified by the environment variable WEBDAV_BACKEND. Note that during forwarding, the path prefix "/webdav" will be removed.
**Use hacdias/webdav as default WebDAV backend server**
The docker-compose.yaml provides an example setup to use the docker image [hacdias/webdav](https://github.com/hacdias/webdav) as the WebDAV backend server. An example for the configuration of the WebDAV server is also provided in webdav.yaml.
