Version: 3.x.x

Server configuration

As the Server is based on Spring framework, it follows its configuration standards. You can configure Tolgee by providing a configuration file, provide configuration properties as command line arguments when you run Tolgee with java -jar command, or as environment variables.

Example configuration files:

YAML
.env
application.properties

config.yaml
tolgee:
  authentication:
    enabled: true
    initial-password: admin
    initial-username: admin
    jwt-secret: my_jwt_secret
  machine-translation:
    google:
      api-key: my_google_api_key
  smtp:
    auth: true
    from: Tolgee <no-reply@mydomain.com>
    host: email-smtp.regional-region.amazonaws.com
    password: 'omg/my/password'
    port: 465
    ssl-enabled: true
    username: user@company.com

Server settings

Prefix: server

These properties are used to configure the server.

port
Port on which Tolgee exposes itself. (default: 8080)

Spring settings

Prefix: spring

These properties are used to configure Spring framework.

Data source settings

Prefix: spring.datasource

Since Tolgee is built on Spring framework, you have to edit following configuration props to configure its database connection. These properties can be omitted when using Postgres autostart, which is enabled by default.

url
The url of the datasource in format jdbc:postgresql://<host>:<port>/<dbname>. e.g. jdbc:postgresql://db:5432/postgres
username
Database username. e.g. postgres
password
Database password. e.g. postgres

Tolgee

Prefix: tolgee

Configuration specific to Tolgee.

file-storage-url
Public base path where files are accessible. Used by the user interface.
front-end-url
Public URL where Tolgee is accessible. Used to generate links to Tolgee (e.g. email confirmation link).
max-screenshots-per-key
Maximum amount of screenshots which can be uploaded per API key. (default: 20)
max-translation-text-length
Maximum length of translations. (default: 10000)
max-upload-file-size
Maximum size of uploaded files (in kilobytes). (default: 51200 ≈ 50MB)

Authentication

Prefix: tolgee.authentication

Configuration of Tolgee's authentication.

create-demo-for-initial-user
When enabled, creates Demo project and quick start guide for inital user (default: true)
enabled
Whether authentication is enabled. When authentication is disabled, there are no login screen and no permission control. Users get automatically logged in as the administrator account of the Tolgee instance. This is very useful, when you want to use Tolgee on your local machine, or you just want to test it. (default: true when running with Java directly, false when running via Docker.)
initial-password
Password of initial user. If unspecified, a random password will be generated and stored in the initial.pwd file, located at the root of Tolgee's data path.
tip
Once set, you don't need to set this property anymore, and it is recommended you unset it so the password is not stored in plaintext in config files.
If you set this field to something else, the initial user's password will be updated unless the password was updated once via the Tolgee web UI.

initial-username
Username of initial user.
tip
Tolgee will ask for an email instead of a username - don't worry, just give it the username specified here.
(default: admin)
jwt-expiration
Expiration time of generated JWT tokens in milliseconds. (default: 604800000 = 7 days)
jwt-secret
Secret used to sign JWT authentication tokens with. It will be generated automatically, if not provided. You will be fine with 64 characters long random string.
danger
When running multiple replicas, it is required to set it, or you will be constantly logged out otherwise.

jwt-super-expiration
Expiration time of generated JWT tokens for superuser in milliseconds. (default: 3600000 = 1 hour)
native-enabled
Whether to enable Tolgee-native authentication and registration. When set to false, users will only be able to register and login via third-party SSO options (e.g. OAuth). (default: true)
needs-email-verification
Whether users need to verify their email addresses when creating their account. Requires a valid SMTP configuration. (default: false)
registrations-allowed
Whether users are allowed to register on Tolgee. When set to false, existing users must send invites to projects to new users for them to be able to register. (default: false)
secured-image-retrieval
Whether image assets should be protected by Tolgee. When enabled, all images are served with an access token valid for a set period of time to prevent unauthorized access to images. (default: false)
secured-image-timestamp-max-age
Expiration time of a generated image access token in milliseconds. (default: 600000 = 10 minutes)
user-can-create-organizations
Whether regular users are allowed to create organizations. When false, only administrators can create organizations. By default, when the user has no organization, one is created for them; this doesn't apply when this setting is set to false. In that case, the user without organization has no permissions on the server. (default: true)

GitHub

Prefix: tolgee.authentication.github

info

GitHub authentication can be used in combination with native authentication.

authorization-url
URL to the OAuth authorization screen. Useful if you want to authenticate against a self-hosted GitHub Enterprise Server. (default: https://github.com/login/oauth/access_token)
client-id
OAuth Client ID, obtained in GitHub administration.

URL to GitHub's /user API endpoint. Useful if you want to authenticate against a self-hosted GitHub Enterprise Server. (default: https://api.github.com/user)

Google

Prefix: tolgee.authentication.google

The following instructions explain how to set up Google OAuth. Setting up OAuth 2.0.

authorization-url
URL to Google /token API endpoint. This usually does not need to be changed. (default: https://oauth2.googleapis.com/token)
client-id
OAuth Client ID, obtained in Google Cloud Console.
client-secret
OAuth Client secret, obtained in Google Cloud Console.
user-url
URL to Google /userinfo API endpoint. This usually does not need to be changed. (default: https://www.googleapis.com/oauth2/v3/userinfo)
workspace-domain
The registration can be limited to users of a Google Workspace domain. Multiple Google Workspace domains can be separated by a comma ,. If nothing is set, anyone can log in with their Google account.

OAuth2

Prefix: tolgee.authentication.oauth2

OAuth 2.0 is the industry-standard protocol for authorization. This enables the integration of a wide range of authorization providers into tolgee, such as Auth0, KeyCloak, Okta and others.

authorization-url
URL to OAuth2 authorize API endpoint. This endpoint will exposed to the frontend.
client-id
OAuth2 Client ID
client-secret
OAuth2 Client secret
scopes
Oauth2 scopes (as list) Tolgee absolutely requires rights to view the email and user information (also known as openid data). In most cases the scopes openid email profile is used for this. (But can also be different depending on the provider) (default: [])
token-url
URL to OAuth2 token API endpoint.
user-url
URL to OAuth2 userinfo API endpoint.
~~user-can-create-projects~~
Removed in: 2.33.0
Whether regular users are allowed to create projects. When disabled, only administrators can create projects (default: true)
~~create-initial-user~~
Removed in: 3.31.0
If true, Tolgee creates initial user on first start-up. (default: true)
~~ldap.*~~
Removed in: 3.31.0
LDAP-related settings.

Batch operations

Prefix: tolgee.batch

Configuration of batch operations.

concurrency
How many parallel jobs can be run at once on single Tolgee instance (default: 1)

Cache

Prefix: tolgee.cache

At the expense of higher memory footprint, Tolgee can use a cache to reduce the stress on the database and fetch the data it needs faster. Cache is also used to track certain states, such as rate limits.

caffeine-max-size
Maximum size of the Caffeine cache. When exceeded, some entries will be purged from cache. Set to -1 to disable size limitation. This has no effect when Redis cache is used. See Caffeine's documentation about size-based eviction (default: -1)
clean-on-startup
Whether to clean the cache on Tolgee startup (default: true)
default-ttl
TTL of cache data, in milliseconds. (default: 7200000 ≈ 2 hours)
enabled
Whether Tolgee should use a cache. (default: false)
use-redis
Whether Tolgee should use Redis to store cache data instead of storing it in-memory.
info
In a distributed environment, you should use a Redis server to ensure consistent enforcement of rate limits, as they heavily rely on cache. For a simple single-node deployment, in-memory cache is sufficient.
info
Tolgee uses Redisson to interface with the Redis server. You can find the properties Redisson expects here.
(default: false)

Content Delivery

Prefix: tolgee.content-delivery
