Introduction

The WebDAV service, like the ocdav service, provides a HTTP API following the WebDAV protocol. It receives HTTP calls from requestors like clients and issues gRPC calls to other services executing these requests. After the called service has finished the request, the webdav service will render their responses in xml and sends them back to the requestor. Also see the ocdav service.

Default Values

WebDav listens on port 9115 by default.

Endpoints Overview

Currently, the webdav service handles request for two functionalities, which are for the Thumbnails and Search service.

Thumbnails Service

The webdav service provides various GET endpoints to get the thumbnails of a file in authenticated and unauthenticated contexts. It also provides thumbnails for spaces on different endpoints.

See the thumbnails service for more information about thumbnails.

Search Service

The webdav service provides access to the search functionality. It offers multiple REPORT endpoints for getting search results.

See the search service for more details about the search functionality.

Scalability

The webdav service does not persist any data and does not cache any information. Therefore multiple instances of this service can be spawned in a bigger deployment like when using container orchestration with Kubernetes, without any extra configuration.

Configuration

Environment Variables

The webdav service is configured via the following environment variables. Read the Environment Variable Types documentation for important details.

Environment variables for the webdav service
Name	Type	Default Value	Description
`OCIS_TRACING_ENABLED` `WEBDAV_TRACING_ENABLED`	bool	false	Activates tracing.
`OCIS_TRACING_TYPE` `WEBDAV_TRACING_TYPE`	string		The type of tracing. Defaults to '', which is the same as 'jaeger'. Allowed tracing types are 'jaeger' and '' as of now.
`OCIS_TRACING_ENDPOINT` `WEBDAV_TRACING_ENDPOINT`	string		The endpoint of the tracing agent.
`OCIS_TRACING_COLLECTOR` `WEBDAV_TRACING_COLLECTOR`	string		The HTTP endpoint for sending spans directly to a collector, i.e. http://jaeger-collector:14268/api/traces. Only used if the tracing endpoint is unset.
`OCIS_LOG_LEVEL` `WEBDAV_LOG_LEVEL`	string		The log level. Valid values are: 'panic', 'fatal', 'error', 'warn', 'info', 'debug', 'trace'.
`OCIS_LOG_PRETTY` `WEBDAV_LOG_PRETTY`	bool	false	Activates pretty log output.
`OCIS_LOG_COLOR` `WEBDAV_LOG_COLOR`	bool	false	Activates colorized log output.
`OCIS_LOG_FILE` `WEBDAV_LOG_FILE`	string		The path to the log file. Activates logging to this file if set.
`WEBDAV_DEBUG_ADDR`	string	127.0.0.1:9119	Bind address of the debug server, where metrics, health, config and debug endpoints will be exposed.
`WEBDAV_DEBUG_TOKEN`	string		Token to secure the metrics endpoint.
`WEBDAV_DEBUG_PPROF`	bool	false	Enables pprof, which can be used for profiling.
`WEBDAV_DEBUG_ZPAGES`	bool	false	Enables zpages, which can be used for collecting and viewing in-memory traces.
`WEBDAV_HTTP_ADDR`	string	127.0.0.1:9115	The bind address of the HTTP service.
`WEBDAV_HTTP_ROOT`	string	/	Subdirectory that serves as the root for this HTTP service.
`OCIS_CORS_ALLOW_ORIGINS` `WEBDAV_CORS_ALLOW_ORIGINS`	[]string	[*]	A list of allowed CORS origins. See following chapter for more details: Access-Control-Allow-Origin at https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Allow-Origin. See the Environment Variable Types description for more details.
`OCIS_CORS_ALLOW_METHODS` `WEBDAV_CORS_ALLOW_METHODS`	[]string	[GET POST PUT PATCH DELETE OPTIONS]	A list of allowed CORS methods. See following chapter for more details: Access-Control-Request-Method at https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Request-Method. See the Environment Variable Types description for more details.
`OCIS_CORS_ALLOW_HEADERS` `WEBDAV_CORS_ALLOW_HEADERS`	[]string	[Authorization Origin Content-Type Accept X-Requested-With X-Request-Id Cache-Control]	A list of allowed CORS headers. See following chapter for more details: Access-Control-Request-Headers at https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Request-Headers. See the Environment Variable Types description for more details.
`OCIS_CORS_ALLOW_CREDENTIALS` `WEBDAV_CORS_ALLOW_CREDENTIALS`	bool	true	Allow credentials for CORS.See following chapter for more details: Access-Control-Allow-Credentials at https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Allow-Credentials.
`OCIS_HTTP_TLS_ENABLED`	bool	false	Activates TLS for the http based services using the server certifcate and key configured via OCIS_HTTP_TLS_CERTIFICATE and OCIS_HTTP_TLS_KEY. If OCIS_HTTP_TLS_CERTIFICATE is not set a temporary server certificate is generated - to be used with PROXY_INSECURE_BACKEND=true.
`OCIS_HTTP_TLS_CERTIFICATE`	string		Path/File name of the TLS server certificate (in PEM format) for the http services.
`OCIS_HTTP_TLS_KEY`	string		Path/File name for the TLS certificate key (in PEM format) for the server certificate to use for the http services.
`OCIS_DISABLE_PREVIEWS` `WEBDAV_DISABLE_PREVIEWS`	bool	false	Set this option to 'true' to disable rendering of thumbnails triggered via webdav access. Note that when disabled, all access to preview related webdav paths will return a 404.
`OCIS_URL` `OCIS_PUBLIC_URL`	string	https://127.0.0.1:9200	URL, where oCIS is reachable for users.
`WEBDAV_WEBDAV_NAMESPACE`	string	/users/{{.Id.OpaqueId}}	CS3 path layout to use when forwarding /webdav requests
`OCIS_REVA_GATEWAY`	string	com.owncloud.api.gateway	CS3 gateway used to look up user metadata
`OCIS_REVA_GATEWAY_TLS_MODE`	string		TLS mode for grpc connection to the CS3 gateway endpoint. Possible values are 'off', 'insecure' and 'on'. 'off': disables transport security for the clients. 'insecure' allows using transport security, but disables certificate verification (to be used with the autogenerated self-signed certificates). 'on' enables transport security, including server certificate verification.
`OCIS_REVA_GATEWAY_TLS_CACERT`	string		The root CA certificate used to validate the gateway’s TLS certificate.

YAML Example

Note that the filename shown below has been chosen on purpose.
See the Configuration File Naming for details when setting up your own configuration.
