Introduction

The Infinite Scale OCS service (open collaboration services) serves mainly one purpose: it has an endpoint for signing keys which the web frontend accesses when uploading data.

Default Values

OCS listens on port 9110 by default.

Signing-Keys Endpoint

The ocs service provides an endpoint /cloud/user/signing-key which is accessed from the web frontend via GET to request a signing key used for uploads.

Signing-Keys Store

To authenticate presigned URLs, the proxy service needs to read the signing keys from a store that is populated by the ocs service.

The following stores can be configured via the OCS_PRESIGNEDURL_SIGNING_KEYS_STORE environment variable:

nats-js-kv
Stores data using key-value-store feature of nats jetstream.
redis-sentinel
Stores data in a configured Redis Sentinel cluster.
ocisstoreservice
Stores data in the deprecated Infinite Scale store service.
Requires setting OCS_PRESIGNEDURL_SIGNING_KEYS_STORE_NODES to com.owncloud.api.store.

The memory or ocmem stores cannot be used as they do not share the memory from the ocs service signing key memory store, even in a single process.
Make sure to configure the same store in the proxy service.

Store specific notes:

When using redis-sentinel
The Redis master to use is configured via e.g. OCS_PRESIGNEDURL_SIGNING_KEYS_STORE_NODES in the form of <sentinel-host>:<sentinel-port>/<redis-master> like 10.10.0.200:26379/mymaster.
When using nats-js-kv
It is recommended to set PROXY_PRESIGNEDURL_SIGNING_KEYS_STORE_NODES to the same value as OCS_PRESIGNEDURL_SIGNING_KEYS_STORE_NODES. That way the proxy service uses the same nats instance as the ocs service.
When using ocisstoreservice
The OCS_PRESIGNEDURL_SIGNING_KEYS_STORE_NODES must be set to the service name com.owncloud.api.store. It does not support TTL and stores the presigning keys indefinitely. Also, the store service needs to be started.

Configuration

Environment Variables

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

Environment variables for the ocs service
Name	Type	Default Value	Description
`OCIS_TRACING_ENABLED` `OCS_TRACING_ENABLED`	bool	false	Activates tracing.
`OCIS_TRACING_TYPE` `OCS_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` `OCS_TRACING_ENDPOINT`	string		The endpoint of the tracing agent.
`OCIS_TRACING_COLLECTOR` `OCS_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` `OCS_LOG_LEVEL`	string		The log level. Valid values are: 'panic', 'fatal', 'error', 'warn', 'info', 'debug', 'trace'.
`OCIS_LOG_PRETTY` `OCS_LOG_PRETTY`	bool	false	Activates pretty log output.
`OCIS_LOG_COLOR` `OCS_LOG_COLOR`	bool	false	Activates colorized log output.
`OCIS_LOG_FILE` `OCS_LOG_FILE`	string		The path to the log file. Activates logging to this file if set.
`OCS_DEBUG_ADDR`	string	127.0.0.1:9114	Bind address of the debug server, where metrics, health, config and debug endpoints will be exposed.
`OCS_DEBUG_TOKEN`	string		Token to secure the metrics endpoint.
`OCS_DEBUG_PPROF`	bool	false	Enables pprof, which can be used for profiling.
`OCS_DEBUG_ZPAGES`	bool	false	Enables zpages, which can be used for collecting and viewing in-memory traces.
`OCS_HTTP_ADDR`	string	127.0.0.1:9110	The bind address of the HTTP service.
`OCS_HTTP_ROOT`	string	/ocs	Subdirectory that serves as the root for this HTTP service.
`OCIS_CORS_ALLOW_ORIGINS` `OCS_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` `OCS_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` `OCS_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` `OCS_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_CACHE_STORE` `OCS_PRESIGNEDURL_SIGNING_KEYS_STORE`	string	nats-js-kv	The type of the signing key store. Supported values are: 'redis-sentinel' and 'nats-js-kv'. See the text description for details.
`OCIS_CACHE_STORE_NODES` `OCS_PRESIGNEDURL_SIGNING_KEYS_STORE_NODES`	[]string	[127.0.0.1:9233]	A list of nodes to access the configured store. 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_TTL` `OCS_PRESIGNEDURL_SIGNING_KEYS_STORE_TTL`	Duration	12h0m0s	Default time to live for signing keys. See the Environment Variable Types description for more details.
`OCIS_CACHE_AUTH_USERNAME` `OCS_PRESIGNEDURL_SIGNING_KEYS_STORE_AUTH_USERNAME`	string		The username to authenticate with the store. Only applies when store type 'nats-js-kv' is configured.
`OCIS_CACHE_AUTH_PASSWORD` `OCS_PRESIGNEDURL_SIGNING_KEYS_STORE_AUTH_PASSWORD`	string		The password to authenticate with the store. Only applies when store type 'nats-js-kv' is configured.
`OCIS_JWT_SECRET` `OCS_JWT_SECRET`	string		The secret to mint and validate jwt tokens.
