Settings
The settings service provides functionality for other services to register new settings as well as storing and retrieving the respective settings' values.
Settings Managed
The settings service is currently used for managing the:
- users'
profilesettings like the language and the email notification settings, - possible user roles and their respective permissions,
- assignment of roles to users.
As an example, user profile settings that can be changed in the Web UI must be persistent.
The settings service persists the settings data via the storage-system service.
Caching
The settings service caches the results of queries against the storage backend to provide faster responses. The content of this cache is independent of the cache used in the storage-system service as it caches directory listing and settings content stored in files.
The store used for the cache can be configured using the SETTINGS_CACHE_STORE environment variable. Possible stores are:
memory: Basic in-memory store and the default.redis-sentinel: Stores data in a configured Redis Sentinel cluster.nats-js-kv: Stores data using key-value-store feature of nats jetstreamnoop: Stores nothing. Useful for testing. Not recommended in production environments.
Other store types may work but are not supported currently.
Note: The service can only be scaled if not using memory store and the stores are configured identically over all instances!
Note that if you have used one of the deprecated stores, you should reconfigure to one of the supported ones as the deprecated stores will be removed in a later version.
Store specific notes:
- When using
redis-sentinel, the Redis master to use is configured via e.g.OCIS_CACHE_STORE_NODESin the form of<sentinel-host>:<sentinel-port>/<redis-master>like10.10.0.200:26379/mymaster. - When using
nats-js-kvit is recommended to setOCIS_CACHE_STORE_NODESto the same value asOCIS_EVENTS_ENDPOINT. That way the cache uses the same nats instance as the event bus. - When using the
nats-js-kvstore, it is possible to setOCIS_CACHE_DISABLE_PERSISTENCEto instruct nats to not persist cache data on disc.
Settings Management
Infinite Scale services can register settings bundles with the settings service.
Settings Usage
Services can set or query Infinite Scale setting values of a user from settings bundles.
Service Accounts
The settings service needs to know the IDs of service accounts but it doesn't need their secrets. They can be configured using the SETTINGS_SERVICE_ACCOUNTS_IDS envvar. When only using one service account OCIS_SERVICE_ACCOUNT_ID can also be used. All configured service accounts will get a hidden 'service-account' role. This role contains all permissions the service account needs but will not appear calls to the list roles endpoint. It is not possible to assign the 'service-account' role to a normal user.
Translations
The settings service has embedded translations sourced via transifex to provide a basic set of translated languages. These embedded translations are available for all deployment scenarios. In addition, the service supports custom translations, though it is currently not possible to just add custom translations to embedded ones. If custom translations are configured, the embedded ones are not used. To configure custom translations, the SETTINGS_TRANSLATION_PATH environment variable needs to point to a base folder that will contain the translation files. This path must be available from all instances of the userlog service, a shared storage is recommended. Translation files must be of type .po or .mo. For each language, the filename needs to be settings.po (or settings.mo) and stored in a folder structure defining the language code. In general the path/name pattern for a translation file needs to be:
{SETTINGS_TRANSLATION_PATH}/{language-code}/LC_MESSAGES/settings.po
The language code pattern is composed of language[_territory] where language is the base language and _territory is optional and defines a country.
For example, for the language de, one needs to place the corresponding translation files to {SETTINGS_TRANSLATION_PATH}/de_DE/LC_MESSAGES/settings.po.
Important: For the time being, the embedded ownCloud Web frontend only supports the main language code but does not handle any territory. When strings are available in the language code language_territory, the web frontend does not see it as it only requests language. In consequence, any translations made must exist in the requested language to avoid a fallback to the default.
Translation Rules
- If a requested language code is not available, the service tries to fall back to the base language if available. For example, if the requested language-code
de_DEis not available, the service tries to fall back to translations in thedefolder. - If the base language
deis also not available, the service falls back to the system's default English (en), which is the source of the texts provided by the code.
Default Language
The default language can be defined via the OCIS_DEFAULT_LANGUAGE environment variable. If this variable is not defined, English will be used as default. The value has the ISO 639-1 format ("de", "en", etc.) and is limited by the list supported languages. This setting can be used to set the default language for notification and invitation emails.
Important developer note: the list of supported languages is at the moment not easy defineable, as it is the minimum intersection of languages shown in the WebUI and languages defined in the ocis code for the use of notifications and userlog. Even more, not all languages where there are translations available on transifex, are available in the WebUI respectively for ocis notifications, and the translation rate for existing languages is partially not that high. You will see therefore quite often English default strings though a supported language may exist and was selected.
The OCIS_DEFAULT_LANGUAGE setting impacts the notification and userlog services and the WebUI. Note that translations must exist for all named components to be presented correctly.

If
OCIS_DEFAULT_LANGUAGEis not set, the expected behavior is:- The
notificationanduserlogservices and the WebUI use English by default until a user sets another language in the WebUI via Account -> Language. - If a user sets another language in the WebUI in Account -> Language, then the
notificationanduserlogservices and WebUI use the language defined by the user. If no translation is found, it falls back to English.

Custom Roles
It is possible to replace the default ocis roles (admin, user) with custom roles that contain custom permissions. One can set SETTINGS_BUNDLES_PATH to the path of a json file containing the new roles.
Role Example:
[
{
"id": "38071a68-456a-4553-846a-fa67bf5596cc", // ID of the role. Recommendation is to use a random uuidv4. But any unique string will do.
"name": "user-light", // Internal name of the role. This is used by the system to identify the role. Any string will do here, but it should be unique among the other roles.
"type": "TYPE_ROLE", // Always use `TYPE_ROLE`
"extension": "ocis-roles", // Always use `ocis-roles`
"displayName": "User Light", // DisplayName of the role used in webui
"settings": [
], // Permissions attached to the role. See Details below.
"resource": {
"type": "TYPE_SYSTEM" // Always use `TYPE_SYSTEM`
}
}
]
To create custom roles:
- Copy the role example to a
jsonfile. - Change
id,name, anddisplayNameto your liking. - Copy the desired permissions from the
user-all-permissionsexample below to thesettingsarray of the role. - Set the
SETTINGS_BUNDLE_PATHenvvar to the path of the json file and start ocis
