Environment Variables

Name	Type	Default Value	Description
OCIS_TRACING_ENABLED STORAGE_SYSTEM_TRACING_ENABLED	bool	false	Activates tracing.
OCIS_TRACING_TYPE STORAGE_SYSTEM_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 STORAGE_SYSTEM_TRACING_ENDPOINT	string		The endpoint of the tracing agent.
OCIS_TRACING_COLLECTOR STORAGE_SYSTEM_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 STORAGE_SYSTEM_LOG_LEVEL	string		The log level. Valid values are: ‘panic’, ‘fatal’, ’error’, ‘warn’, ‘info’, ‘debug’, ’trace’.
OCIS_LOG_PRETTY STORAGE_SYSTEM_LOG_PRETTY	bool	false	Activates pretty log output.
OCIS_LOG_COLOR STORAGE_SYSTEM_LOG_COLOR	bool	false	Activates colorized log output.
OCIS_LOG_FILE STORAGE_SYSTEM_LOG_FILE	string		The path to the log file. Activates logging to this file if set.
STORAGE_SYSTEM_DEBUG_ADDR	string	127.0.0.1:9217	Bind address of the debug server, where metrics, health, config and debug endpoints will be exposed.
STORAGE_SYSTEM_DEBUG_TOKEN	string		Token to secure the metrics endpoint
STORAGE_SYSTEM_DEBUG_PPROF	bool	false	Enables pprof, which can be used for profiling
STORAGE_SYSTEM_DEBUG_ZPAGES	bool	false	Enables zpages, which can be used for collecting and viewing in-memory traces.
STORAGE_SYSTEM_GRPC_ADDR	string	127.0.0.1:9215	The bind address of the GRPC service.
STORAGE_SYSTEM_GRPC_PROTOCOL	string	tcp	The transport protocol of the GPRC service.
STORAGE_SYSTEM_HTTP_ADDR	string	127.0.0.1:9216	The bind address of the HTTP service.
STORAGE_SYSTEM_HTTP_PROTOCOL	string	tcp	The transport protocol of the HTTP service.
OCIS_JWT_SECRET STORAGE_SYSTEM_JWT_SECRET	string		The secret to mint and validate jwt tokens.
OCIS_REVA_GATEWAY	string	com.owncloud.api.gateway	The CS3 gateway endpoint.
OCIS_GRPC_CLIENT_TLS_MODE	string		TLS mode for grpc connection to the go-micro based grpc services. 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_GRPC_CLIENT_TLS_CACERT	string		Path/File name for the root CA certificate (in PEM format) used to validate TLS server certificates of the go-micro based grpc services.
OCIS_SYSTEM_USER_ID	string		ID of the oCIS storage-system system user. Admins need to set the ID for the STORAGE-SYSTEM system user in this config option which is then used to reference the user. Any reasonable long string is possible, preferably this would be an UUIDv4 format.
OCIS_SYSTEM_USER_API_KEY	string		API key for the STORAGE-SYSTEM system user.
STORAGE_SYSTEM_SKIP_USER_GROUPS_IN_TOKEN	bool	false	Disables the loading of user’s group memberships from the reva access token.
OCIS_CACHE_STORE STORAGE_SYSTEM_CACHE_STORE	string	memory	The type of the cache store. Supported values are: ‘memory’, ‘redis-sentinel’, ’nats-js-kv’, ’noop’. See the text description for details.
OCIS_CACHE_STORE_NODES STORAGE_SYSTEM_CACHE_STORE_NODES	[]string	[127.0.0.1:9233]	A list of nodes to access the configured store. This has no effect when ‘memory’ or ‘ocmem’ stores are configured. Note that the behaviour how nodes are used is dependent on the library of the configured store. See the Environment Variable Types description for more details.
OCIS_CACHE_DATABASE	string	storage-system	The database name the configured store should use.
OCIS_CACHE_TTL STORAGE_SYSTEM_CACHE_TTL	Duration	24m0s	Default time to live for user info in the user info cache. Only applied when access tokens has no expiration. See the Environment Variable Types description for more details.
OCIS_CACHE_SIZE STORAGE_SYSTEM_CACHE_SIZE	int	0	The maximum quantity of items in the user info cache. Only applies when store type ‘ocmem’ is configured. Defaults to 512 which is derived from the ocmem package though not exclicitely set as default.
OCIS_CACHE_DISABLE_PERSISTENCE STORAGE_SYSTEM_CACHE_DISABLE_PERSISTENCE	bool	false	Disables persistence of the cache. Only applies when store type ’nats-js-kv’ is configured. Defaults to false.
OCIS_CACHE_AUTH_USERNAME STORAGE_SYSTEM_CACHE_AUTH_USERNAME	string		Username for the configured store. Only applies when store type ’nats-js-kv’ is configured.
OCIS_CACHE_AUTH_PASSWORD STORAGE_SYSTEM_CACHE_AUTH_PASSWORD	string		Password for the configured store. Only applies when store type ’nats-js-kv’ is configured.
STORAGE_SYSTEM_DRIVER	string	ocis	The driver which should be used by the service.
OCIS_DECOMPOSEDFS_METADATA_BACKEND STORAGE_SYSTEM_OCIS_METADATA_BACKEND	string	messagepack	The backend to use for storing metadata. Supported values are ‘messagepack’ and ‘xattrs’. The setting ‘messagepack’ uses a dedicated file to store file metadata while ‘xattrs’ uses extended attributes to store file metadata. Defaults to ‘messagepack’.
STORAGE_SYSTEM_OCIS_ROOT	string	/var/lib/ocis/storage/metadata	Path for the directory where the STORAGE-SYSTEM service stores it’s persistent data. If not defined, the root directory derives from $OCIS_BASE_DATA_PATH:/storage.
STORAGE_SYSTEM_OCIS_MAX_ACQUIRE_LOCK_CYCLES	int	20	When trying to lock files, ocis will try this amount of times to acquire the lock before failing. After each try it will wait for an increasing amount of time. Values of 0 or below will be ignored and the default value of 20 will be used.
STORAGE_SYSTEM_OCIS_LOCK_CYCLE_DURATION_FACTOR	int	30	When trying to lock files, ocis will multiply the cycle with this factor and use it as a millisecond timeout. Values of 0 or below will be ignored and the default value of 30 will be used.
STORAGE_SYSTEM_DATA_SERVER_URL	string	http://localhost:9216/data	URL of the data server, needs to be reachable by other services using this service.
