# OAuth

Variable Description Default Value
OAUTH_PROVIDERS CSV of oAuth providers you want to use. --

For each of the OAuth providers you list, you must also provide a number of extra variables. These differ per external service. The following is a list of common required configuration options:

Variable Description Default Value

OAUTH_<PROVIDER>_ACCESS_URL The access URL of the external service --
OAUTH_<PROVIDER>_PROFILE_URL Where Directus can fetch the profile information of the authenticated user. --

Directus relies on grant (opens new window) for the handling of the oAuth flow. Grant includes a lot of default values (opens new window) for popular services. For example, if you use apple as one of your providers, you only have to specify the key and secret, as Grant has the rest covered. Checkout the grant repo (opens new window) for more information.

# Extensions

If you're relying on Docker and/or the directus bootstrap CLI command, you can pass the following two environment variables to automatically configure the first user:

Variable Description Default Value
ADMIN_EMAIL The email address of the first user that's automatically created when using directus bootstrap. --
ADMIN_PASSWORD The password of the first user that's automatically created when using directus bootstrap. --

# Type Casting and Nesting

Environment variables are automatically type cast based on the structure of the variable, for example:

PUBLIC_URL="https://example.com"
// "https://example.com"

DB_HOST="3306"
// 3306

CORS_ENABLED="false"
// false

STORAGE_LOCATIONS="s3,local,example"
// ["s3", "local", "example"]

In cases where the environment variables are converted to a configuration object for third party library use, like in DB_* or RATE_LIMITER_REDIS_*, the environment variable will be converted to camelCase. You can use a double underscore (__) for nested objects:

DB_CLIENT="pg"
DB_CONNECTION_STRING="postgresql://postgres:example@127.0.0.1"
DB_SSL__REJECT_UNAUTHORIZED="false"

{
	client: "pg",
	connectionString: "postgresql://postgres:example@127.0.0.1",
	ssl: {
		rejectUnauthorized: false
	}
}

# Environment Syntax Prefix

Directus will attempt to automatically type cast environment variables based on context clues (see above). If you have a specific need for a given type, you can tell Directus what type to use for the given value by prefixing the value with {type}:. The following types are available:

Syntax Prefix Example Output
string string:value "value"
number number:3306 3306
regex regex:/\.example\.com$/ /\.example\.com$/
array array:https://example.com,https://example2.com ["https://example.com","https://example2.com"]
