Configuration Options

Environment variables are used for all configuration within a Directus project. These variables can be defined in a number of ways, which we cover below.

Configuration Files

By default, Directus will read the .env file located next to your project's package.json (typically in the root folder of your project) for its configuration. You can change this path and filename by setting the CONFIG_PATH environment variable before starting Directus. For example:

bash
CONFIG_PATH="/path/to/config.js" npx directus start
CONFIG_PATH="/path/to/config.js" npx directus start

In case you prefer using a configuration file instead of environment variables, you can also use the CONFIG_PATH environment variable to instruct Directus to use a local configuration file instead of environment variables. The config file can be one of the following formats:

.env

If the config path has no file extension, or a file extension that's not one of the other supported formats, Directus will try reading the file config path as environment variables. This has the following structure:

HOST="0.0.0.0"
PORT=8055

DB_CLIENT="pg"
DB_HOST="localhost"
DB_PORT=5432

etc
HOST="0.0.0.0"
PORT=8055

DB_CLIENT="pg"
DB_HOST="localhost"
DB_PORT=5432

etc

config.json

If you prefer a single JSON file for your configuration, create a JSON file with the environment variables as keys, for example:

CONFIG_PATH="/path/to/config.json"
CONFIG_PATH="/path/to/config.json"
json
{
	"HOST": "0.0.0.0",
	"PORT": 8055,

	"DB_CLIENT": "pg",
	"DB_HOST": "localhost",
	"DB_PORT": 5432

	// etc
}
{
	"HOST": "0.0.0.0",
	"PORT": 8055,

	"DB_CLIENT": "pg",
	"DB_HOST": "localhost",
	"DB_PORT": 5432

	// etc
}

config.yaml

Similar to JSON, you can use a .yaml (or .yml) file for your config:

CONFIG_PATH="/path/to/config.yaml"
CONFIG_PATH="/path/to/config.yaml"
yaml
HOST: 0.0.0.0
PORT: 8055

DB_CLIENT: pg
DB_HOST: localhost
DB_PORT: 5432
#
# etc
HOST: 0.0.0.0
PORT: 8055

DB_CLIENT: pg
DB_HOST: localhost
DB_PORT: 5432
#
# etc

config.js

Using a JavaScript file for your config allows you to dynamically generate the configuration of the project during startup.

By default, the file is expected to be a ESM, while CommonJS is supported too by using .cjs as the file extension.

The JavaScript configuration supports two different formats, either an Object Structure where the key is the environment variable name:

js
export default {
	HOST: '0.0.0.0',
	PORT: 8055,

	DB_CLIENT: 'pg',
	DB_HOST: 'localhost',
	DB_PORT: 5432,

	// etc
};
export default {
	HOST: '0.0.0.0',
	PORT: 8055,

	DB_CLIENT: 'pg',
	DB_HOST: 'localhost',
	DB_PORT: 5432,

	// etc
};
js
module.exports = {
	HOST: '0.0.0.0',
	PORT: 8055,

	DB_CLIENT: 'pg',
	DB_HOST: 'localhost',
	DB_PORT: 5432,

	// etc
};
module.exports = {
	HOST: '0.0.0.0',
	PORT: 8055,

	DB_CLIENT: 'pg',
	DB_HOST: 'localhost',
	DB_PORT: 5432,

	// etc
};

Or a Function Structure that returns the same object format as above. The function gets process.env as its parameter.

js
export default function (env) {
	return {
		HOST: '0.0.0.0',
		PORT: 8055,

		DB_CLIENT: 'pg',
		DB_HOST: 'localhost',
		DB_PORT: 5432,

		// etc
	};
}
export default function (env) {
	return {
		HOST: '0.0.0.0',
		PORT: 8055,

		DB_CLIENT: 'pg',
		DB_HOST: 'localhost',
		DB_PORT: 5432,

		// etc
	};
}
js
module.exports = function (env) {
	return {
		HOST: '0.0.0.0',
		PORT: 8055,

		DB_CLIENT: 'pg',
		DB_HOST: 'localhost',
		DB_PORT: 5432,

		// etc
	};
};
module.exports = function (env) {
	return {
		HOST: '0.0.0.0',
		PORT: 8055,

		DB_CLIENT: 'pg',
		DB_HOST: 'localhost',
		DB_PORT: 5432,

		// etc
	};
};

Environment Variable Files

Any of the environment variable values can be imported from a file, by appending _FILE to the environment variable name. This is especially useful when used in conjunction with Docker Secrets, so you can keep sensitive data out of your compose files. For example:

DB_PASSWORD_FILE="/run/secrets/db_password"
DB_PASSWORD_FILE="/run/secrets/db_password"

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"]
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 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
	}
}
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. 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 PrefixExampleOutput
stringstring:value"value"
numbernumber:33063306
regexregex:\.example\.com$/\.example\.com$/
arrayarray:https://example.com,https://example2.com
array:string:https://example.com,regex:\.example3\.com$
["https://example.com", "https://example2.com"]
["https://example.com", /\.example3\.com$/]
jsonjson:{"items": ["example1", "example2"]}{"items": ["example1", "example2"]}

Additional Logger Variables

All LOGGER_* environment variables are passed to the options configuration of a Pino instance. All LOGGER_HTTP* environment variables are passed to the options configuration of a Pino-http instance. Based on your project's needs, you can extend the LOGGER_* environment variables with any config you need to pass to the logger instance. If a LOGGER_LEVELS key is added, these values will be passed to the logger frontmatter, as described here for example. The format for adding LEVELS values is: LOGGER_LEVELS="trace:DEBUG,debug:DEBUG,info:INFO,warn:WARNING,error:ERROR,fatal:CRITICAL"

Server

VariableDescriptionDefault Value
SERVER_KEEP_ALIVE_TIMEOUTTimeout in milliseconds for socket to be destroyedserver.keepAliveTimeout
SERVER_HEADERS_TIMEOUTTimeout in milliseconds to parse HTTP headersserver.headersTimeout
SERVER_SHUTDOWN_TIMEOUTTimeout in milliseconds before the server is forcefully shut down1000

Additional Server Variables

All SERVER_* environment variables are merged with server instance properties created from http.Server. This allows to configure server behind a proxy, a load balancer, etc. Be careful to not override methods of this instance otherwise you may incur into unexpected behaviors.

Database

VariableDescriptionDefault Value

DB_HEALTHCHECK_THRESHOLDHealthcheck timeout threshold in ms.150

Additional Database Variables

All DB_* environment variables are passed to the connection configuration of a Knex instance. This means, based on your project's needs, you can extend the DB_* environment variables with any config you need to pass to the database instance.

This includes:

  • DB_POOL__ prefixed options which are passed to tarn.js.

  • DB_SSL__ prefixed options which are passed to the respective database driver.

    • For example DB_SSL__CA which can be used to specify a custom CA certificate for SSL connections. This is required if the database server CA is not part of Node.js' trust store.

      Note: DB_SSL__CA_FILE may be preferred to load the CA directly from a file, see Environment Variable Files for more information.

Redis

Directus requires Redis for multi-container deployments. This ensures that things like caching, rate-limiting, and WebSockets work reliably across multiple containers of Directus.

VariableDescriptionDefault Value
REDISRedis connection string, e.g., redis://user:password@127.0.0.1:6380/4. Using this will ignore the other Redis connection parameter environment variables--
REDIS_HOSTHostname of the Redis instance, e.g., "127.0.0.1"--
REDIS_PORTPort of the Redis instance, e.g., 6379--
REDIS_USERNAMEUsername for your Redis instance, e.g., "default"--
REDIS_PASSWORDPassword for your Redis instance, e.g., "yourRedisPassword"--

Redis is required when you run Directus load balanced across multiple containers/processes.

Security

VariableDescriptionDefault Value
KEYUnique identifier for the project.--
SECRETSecret string for the project.--
ACCESS_TOKEN_TTLThe duration that the access token is valid.15m
REFRESH_TOKEN_TTLThe duration that the refresh token is valid, and also how long users stay logged-in to the App.7d

ASSETS_CONTENT_SECURITY_POLICYCustom overrides for the Content-Security-Policy header for the /assets endpoint. See helmet's documentation on helmet.contentSecurityPolicy() for more information.--
IMPORT_IP_DENY_LIST[1]Deny importing files from these IP addresses / IP ranges / CIDR blocks. Use 0.0.0.0 to match any local IP address.0.0.0.0,169.254.169.254
CONTENT_SECURITY_POLICY_*Custom overrides for the Content-Security-Policy header. See helmet's documentation on helmet.contentSecurityPolicy() for more information.--
HSTS_ENABLEDEnable the Strict-Transport-Security policy header.false
HSTS_*Custom overrides for the Strict-Transport-Security header. See helmet's documentation for more information.--

[1] localhost can get resolved to ::1 as well as 127.0.0.1 depending on the system - ensure to include both if you want to specifically block localhost.

Cookie Strictness

Browser are pretty strict when it comes to third-party cookies. If you're running into unexpected problems when running your project and API on different domains, make sure to verify your configuration for REFRESH_TOKEN_COOKIE_NAME, REFRESH_TOKEN_COOKIE_SECURE and REFRESH_TOKEN_COOKIE_SAME_SITE.

Hashing

VariableDescriptionDefault Value
HASH_MEMORY_COSTHow much memory to use when generating hashes, in KiB.4096 (4 MiB)
HASH_LENGTHThe length of the hash function output in bytes.32
HASH_TIME_COSTThe amount of passes (iterations) used by the hash function. It increases hash strength at the cost of time required to compute.3
HASH_PARALLELISMThe amount of threads to compute the hash on. Each thread has a memory pool with HASH_MEMORY_COST size.1 (single thread)
HASH_TYPEThe variant of the hash function (0: argon2d, 1: argon2i, or 2: argon2id).2 (argon2id)
HASH_ASSOCIATED_DATAAn extra and optional non-secret value. The value will be included Base64 encoded in the parameters portion of the digest.--

Argon2's hashing function is used by Directus for three purposes: 1) hashing user passwords, 2) generating hashes for the Hash field type in collections, and 3) the generate a hash API endpoint.

All HASH_* environment variable parameters are passed to the argon2.hash function. See the node-argon2 library options page for reference.

Memory Usage

Modifying HASH_MEMORY_COST and/or HASH_PARALLELISM will affect the amount of memory directus uses when computing hashes; each thread gets HASH_MEMORY_COST amount of memory, so the total additional memory will be these two values multiplied. This may cause out of memory errors, especially when running in containerized environments.

CORS

VariableDescriptionDefault Value
CORS_ENABLEDWhether or not to enable the CORS headers.false
CORS_ORIGINValue for the Access-Control-Allow-Origin header. Use true to match the Origin header, or provide a domain or a CSV of domains for specific accessfalse
CORS_METHODSValue for the Access-Control-Allow-Methods header.GET,POST,PATCH,DELETE
CORS_ALLOWED_HEADERSValue for the Access-Control-Allow-Headers header.Content-Type,Authorization
CORS_EXPOSED_HEADERSValue for the Access-Control-Expose-Headers header.Content-Range
CORS_CREDENTIALSWhether or not to send the Access-Control-Allow-Credentials header.true
CORS_MAX_AGEValue for the Access-Control-Max-Age header.18000

More Details

For more details about each configuration variable, please see the CORS package documentation.

Rate Limiting

You can use the built-in rate-limiter to prevent users from hitting the API too much. Simply enabling the rate-limiter will set a default maximum of 50 requests per second, tracked in memory.

VariableDescriptionDefault Value
RATE_LIMITER_ENABLEDWhether or not to enable rate limiting per IP on the API.false
RATE_LIMITER_POINTSThe amount of allowed hits per duration.50
RATE_LIMITER_DURATIONThe time window in seconds in which the points are counted.1
RATE_LIMITER_STOREWhere to store the rate limiter counts. One of memory, redis.memory
RATE_LIMITER_HEALTHCHECK_THRESHOLDHealthcheck timeout threshold in ms.150
RATE_LIMITER_GLOBAL_ENABLEDWhether or not to enable global rate limiting on the API.false
RATE_LIMITER_GLOBAL_POINTSThe total amount of allowed hits per duration.1000
RATE_LIMITER_GLOBAL_DURATIONThe time window in seconds in which the points are counted.1
RATE_LIMITER_GLOBAL_HEALTHCHECK_THRESHOLDHealthcheck timeout threshold in ms.150
RATE_LIMITER_GLOBAL_STOREWhere to store the rate limiter counts. One of memory, redis.memory

Based on the RATE_LIMITER_STORE/RATE_LIMITER_GLOBAL_STORE used, you must also provide the following configurations:

Example: Basic

# 10 requests per 5 seconds
RATE_LIMITER_POINTS="10"
RATE_LIMITER_DURATION="5"

# globally 100 requests per 5 seconds
RATE_LIMITER_GLOBAL_POINTS="100"
RATE_LIMITER_GLOBAL_DURATION="5"
# 10 requests per 5 seconds
RATE_LIMITER_POINTS="10"
RATE_LIMITER_DURATION="5"

# globally 100 requests per 5 seconds
RATE_LIMITER_GLOBAL_POINTS="100"
RATE_LIMITER_GLOBAL_DURATION="5"

Pressure-based rate limiter

This rate-limiter prevents the API from accepting new requests while the server is experiencing high load. This continuously monitors the current event loop and memory usage, and error out requests with a 503 early when the system is overloaded.

VariableDescriptionDefault Value
PRESSURE_LIMITER_ENABLEDWhether or not to enable pressure-based rate limiting on the API.true
PRESSURE_LIMITER_SAMPLE_INTERVALThe time window for measuring pressure in ms.250
PRESSURE_LIMITER_MAX_EVENT_LOOP_UTILIZATIONThe maximum allowed utilization where 1 is 100% loop utilization.0.99
PRESSURE_LIMITER_MAX_EVENT_LOOP_DELAYThe maximum amount of time the current loop can be delayed in ms.500
PRESSURE_LIMITER_MAX_MEMORY_RSSThe maximum allowed memory Resident Set Size (RSS) in bytes.false
PRESSURE_LIMITER_MAX_MEMORY_HEAP_USEDThe maximum allowed heap usage in bytes.false
PRESSURE_LIMITER_RETRY_AFTERSets the Retry-After header when the rate limiter is triggered.false

Cache

Directus has a built-in data-caching option. Enabling this will cache the output of requests (based on the current user and exact query parameters used) into configured cache storage location. This drastically improves API performance, as subsequent requests are served straight from this cache. Enabling cache will also make Directus return accurate cache-control headers. Depending on your setup, this will further improve performance by caching the request in middleman servers (like CDNs) and even the browser.

Internal Caching

In addition to data-caching, Directus also does some internal caching. Note CACHE_SCHEMA and CACHE_PERMISSIONS which are enabled by default. These speed up the overall performance of Directus, as we don't want to introspect the whole database or check all permissions on every request.

Assets Cache

Cache-Control and Last-Modified headers for the /assets endpoint are separate from the regular data-cache. Last-Modified comes from modified_on DB field. This is useful as it's often possible to cache assets for far longer than you would cache database content. To learn more, see Assets.

VariableDescriptionDefault Value
CACHE_ENABLEDWhether or not data caching is enabled.false
CACHE_TTL[1]How long the data cache is persisted.5m
CACHE_CONTROL_S_MAXAGEWhether to not to add the s-maxage expiration flag. Set to a number for a custom value.0
CACHE_AUTO_PURGE[2]Automatically purge the data cache on actions that manipulate the data.false
CACHE_AUTO_PURGE_IGNORE_LIST[3]List of collections that prevent cache purging when CACHE_AUTO_PURGE is enabled.directus_activity,directus_presets
CACHE_SYSTEM_TTL[4]How long CACHE_SCHEMA and CACHE_PERMISSIONS are persisted.--
CACHE_SCHEMA[4]Whether or not the database schema is cached. One of false, truetrue
CACHE_PERMISSIONS[4]Whether or not the user permissions are cached. One of false, truetrue
CACHE_NAMESPACEHow to scope the cache data.system-cache
CACHE_STORE[5]Where to store the cache data. Either memory, redis.memory
CACHE_STATUS_HEADERIf set, returns the cache status in the configured header. One of HIT, MISS.--
CACHE_VALUE_MAX_SIZEMaximum size of values that will be cached. Accepts number of bytes, or human readable string. Use false for no limitfalse
CACHE_SKIP_ALLOWEDWhether requests can use the Cache-Control header with no-store to skip data caching.false
CACHE_HEALTHCHECK_THRESHOLDHealthcheck timeout threshold in ms.150

[1] CACHE_TTL Based on your project's needs, you might be able to aggressively cache your data, only requiring new data to be fetched every hour or so. This allows you to squeeze the most performance out of your Directus instance. This can be incredibly useful for applications where you have a lot of (public) read-access and where updates aren't real-time (for example a website). CACHE_TTL uses ms to parse the value, so you configure it using human readable values (like 2 days, 7 hrs, 5m).

[2] CACHE_AUTO_PURGE allows you to keep the Directus API real-time, while still getting the performance benefits on quick subsequent reads.

[3] The cache has to be manually cleared when requiring to access updated results for collections in CACHE_AUTO_PURGE_IGNORE_LIST.

[4] Not affected by the CACHE_ENABLED value.

[5] CACHE_STORE For larger projects, you most likely don't want to rely on local memory for caching. Instead, you can use the above CACHE_STORE environment variable to use redis as the cache store.

File Storage

By default, Directus stores all uploaded files locally on disk. However, you can also configure Directus to use S3, Google Cloud Storage, Azure, Cloudinary or Supabase. You can also configure multiple storage adapters at the same time. This allows you to choose where files are being uploaded on a file-by-file basis. In the Admin App, files will automatically be uploaded to the first configured storage location (in this case local). The used storage location is saved under storage in directus_files.

File Storage Default

If you don't provide any configuration for storage adapters, this default will be used:

STORAGE_LOCATIONS="local"
STORAGE_LOCAL_ROOT="./uploads"
STORAGE_LOCATIONS="local"
STORAGE_LOCAL_ROOT="./uploads"

Case sensitivity

The location value(s) you specify should be capitalized when specifying the additional configuration values. For example, this will not work:

STORAGE_LOCATIONS="s3"
STORAGE_s3_DRIVER="s3" # Will not work, lowercase "s3" ❌
STORAGE_LOCATIONS="s3"
STORAGE_s3_DRIVER="s3" # Will not work, lowercase "s3" ❌

but this will work:

STORAGE_LOCATIONS="s3"
STORAGE_S3_DRIVER="s3" # Will work, "s3" is uppercased ✅
STORAGE_LOCATIONS="s3"
STORAGE_S3_DRIVER="s3" # Will work, "s3" is uppercased ✅
VariableDescriptionDefault Value
STORAGE_LOCATIONSA CSV of storage locations (e.g., local,digitalocean,amazon) to use. You can use any names you'd like for these keys.local

For each of the storage locations listed, you must provide the following configuration:

VariableDescriptionDefault Value

One-way sync

Cloudinary is supported as a storage driver. Changes made on Cloudinary are not synced back to Directus, and Directus won't rely on Cloudinary's asset transformations in the /assets endpoint.

Supabase (supabase)

VariableDescriptionDefault Value
STORAGE_<LOCATION>_SERVICE_ROLEThe admin service role JWT--
STORAGE_<LOCATION>_BUCKETStorage bucket--
STORAGE_<LOCATION>_PROJECT_IDProject id--
STORAGE_<LOCATION>_ENDPOINTOptional custom endpoint--

Endpoint

Using a custom endpoint will overwrite the project id, so you need to provide the full endpoint url.

Example: Multiple Storage Adapters

Below showcases a CSV of storage location names, with a config block for each:

STORAGE_LOCATIONS="local,aws"

STORAGE_LOCAL_DRIVER="local"
STORAGE_LOCAL_ROOT="local"

STORAGE_AWS_KEY="tp15c...510vk"
STORAGE_AWS_SECRET="yk29b...b932n"
STORAGE_AWS_REGION="us-east-2"
STORAGE_AWS_BUCKET="my-files"
STORAGE_LOCATIONS="local,aws"

STORAGE_LOCAL_DRIVER="local"
STORAGE_LOCAL_ROOT="local"

STORAGE_AWS_KEY="tp15c...510vk"
STORAGE_AWS_SECRET="yk29b...b932n"
STORAGE_AWS_REGION="us-east-2"
STORAGE_AWS_BUCKET="my-files"

Metadata

When uploading an image, Directus persists the description, title, and tags from available Exif metadata. For security purposes, collection of additional metadata must be configured:

VariableDescriptionDefault Value
FILE_METADATA_ALLOW_LISTA comma-separated list of metadata keys to collect during file upload. Use * for all[1].ifd0.Make,ifd0.Model,exif.FNumber,exif.ExposureTime,exif.FocalLength,exif.ISOSpeedRatings

[1]: Extracting all metadata might cause memory issues when the file has an unusually large set of metadata

Upload Limits

VariableDescriptionDefault Value
FILES_MAX_UPLOAD_SIZEMaximum file upload size allowed. For example 10mb, 1gb, 10kb--
FILES_MIME_TYPE_ALLOW_LISTAllow list of mime types that are allowed to be uploaded. Supports glob syntax*/*

ASSETS_TRANSFORM_MAX_OPERATIONSThe max number of transform operations that is allowed to be processed (excludes saved presets)5
ASSETS_INVALID_IMAGE_SENSITIVITY_LEVELLevel of sensitivity to invalid images. See the sharp.failOn optionwarning

Image transformations can be fairly heavy on memory usage. If you're using a system with 1GB or less available memory, we recommend lowering the allowed concurrent transformations to prevent you from overflowing your server.

Authentication

VariableDescriptionDefault Value
AUTH_PROVIDERSA comma-separated list of auth providers.--
AUTH_DISABLE_DEFAULTDisable the default auth providerfalse

For each auth provider you list, you must also provide the following configuration:

VariableDescriptionDefault Value

You may also be required to specify additional variables depending on the auth driver. See configuration details below.

Multiple Providers

Directus users can only authenticate using the auth provider they are created with. It is not possible to authenticate with multiple providers for the same user.

Local (local)

The default Directus email/password authentication flow.

No additional configuration required.

SSO (oauth2 and openid)

Directus' SSO integrations provide powerful alternative ways to authenticate into your project. Directus will ask you to login on the external service, and return authenticated with a Directus account linked to that service.

For example, you can login to Directus using a GitHub account by creating an OAuth 2.0 app in GitHub and adding the following configuration to Directus:

AUTH_PROVIDERS="github"

AUTH_GITHUB_DRIVER="oauth2"
AUTH_GITHUB_CLIENT_ID="99d3...c3c4"
AUTH_GITHUB_CLIENT_SECRET="34ae...f963"
AUTH_GITHUB_AUTHORIZE_URL="https://github.com/login/oauth/authorize"
AUTH_GITHUB_ACCESS_URL="https://github.com/login/oauth/access_token"
AUTH_GITHUB_PROFILE_URL="https://api.github.com/user"
AUTH_PROVIDERS="github"

AUTH_GITHUB_DRIVER="oauth2"
AUTH_GITHUB_CLIENT_ID="99d3...c3c4"
AUTH_GITHUB_CLIENT_SECRET="34ae...f963"
AUTH_GITHUB_AUTHORIZE_URL="https://github.com/login/oauth/authorize"
AUTH_GITHUB_ACCESS_URL="https://github.com/login/oauth/access_token"
AUTH_GITHUB_PROFILE_URL="https://api.github.com/user"

More example SSO configurations can be found here.

PUBLIC_URL

These flows rely on the PUBLIC_URL variable for redirecting. Ensure the variable is correctly configured.

OAuth 2.0

VariableDescriptionDefault Value
AUTH_<PROVIDER>_CLIENT_IDClient identifier for the OAuth provider.--
AUTH_<PROVIDER>_CLIENT_SECRETClient secret for the OAuth provider.--
AUTH_<PROVIDER>_SCOPEA white-space separated list of permissions to request.email
AUTH_<PROVIDER>_AUTHORIZE_URLAuthorization page URL of the OAuth provider.--
AUTH_<PROVIDER>_ACCESS_URLAccess token URL of the OAuth provider.--
AUTH_<PROVIDER>_PROFILE_URLUser profile URL of the OAuth provider.--
AUTH_<PROVIDER>_IDENTIFIER_KEYUser profile identifier key [1]. Will default to EMAIL_KEY.--

AUTH_<PROVIDER>_ICONSVG icon to display with the login link. See options here.account_circle
AUTH_<PROVIDER>_LABELText to be presented on SSO button within App.<PROVIDER>
AUTH_<PROVIDER>_PARAMSCustom query parameters applied to the authorization URL.--

[1] When authenticating, Directus will match the identifier value from the external user profile to a Directus users "External Identifier".

OpenID

OpenID is an authentication protocol built on OAuth 2.0, and should be preferred over standard OAuth 2.0 where possible.

VariableDescriptionDefault Value
AUTH_<PROVIDER>_CLIENT_IDClient identifier for the external service.--
AUTH_<PROVIDER>_CLIENT_SECRETClient secret for the external service.--
AUTH_<PROVIDER>_SCOPEA white-space separated list of permissions to request.openid profile email
AUTH_<PROVIDER>_ISSUER_URLOpenID .well-known discovery document URL of the external service.--
AUTH_<PROVIDER>_IDENTIFIER_KEYUser profile identifier key [1].sub[2]
AUTH_<PROVIDER>_ALLOW_PUBLIC_REGISTRATIONAutomatically create accounts for authenticating users.false
AUTH_<PROVIDER>_REQUIRE_VERIFIED_EMAILRequire created users to have a verified email address.false
AUTH_<PROVIDER>_DEFAULT_ROLE_IDA Directus role ID to assign created users.--
AUTH_<PROVIDER>_ICONSVG icon to display with the login link. See options here.account_circle
AUTH_<PROVIDER>_LABELText to be presented on SSO button within App.<PROVIDER>
AUTH_<PROVIDER>_PARAMSCustom query parameters applied to the authorization URL.--

[1] When authenticating, Directus will match the identifier value from the external user profile to a Directus users "External Identifier".

[2] sub represents a unique user identifier defined by the OpenID provider. For users not relying on PUBLIC_REGISTRATION it is recommended to use a human-readable identifier, such as email.

LDAP (ldap)

LDAP allows Active Directory users to authenticate and use Directus without having to be manually configured. User information and roles will be assigned from Active Directory.

VariableDescriptionDefault Value
AUTH_<PROVIDER>_CLIENT_URLLDAP connection URL.--
AUTH_<PROVIDER>_BIND_DNBind user [1] distinguished name.--
AUTH_<PROVIDER>_BIND_PASSWORDBind user password.--
AUTH_<PROVIDER>_USER_DNDirectory path containing users.--
AUTH_<PROVIDER>_USER_ATTRIBUTEAttribute to identify the user.cn
AUTH_<PROVIDER>_USER_SCOPEScope of the user search, either base, one, sub [2].one
AUTH_<PROVIDER>_MAIL_ATTRIBUTEUser email attribute.mail

AUTH_<PROVIDER>_LAST_NAME_ATTRIBUTEUser last name attribute.sn
AUTH_<PROVIDER>_GROUP_DN[3]Directory path containing groups.--
AUTH_<PROVIDER>_GROUP_ATTRIBUTEAttribute to identify user as a member of a group.member
AUTH_<PROVIDER>_GROUP_SCOPEScope of the group search, either base, one, sub [2].one
AUTH_<PROVIDER>_DEFAULT_ROLE_IDA fallback Directus role ID to assign created users.--

[1] The bind user must have permission to query users and groups to perform authentication. Anonymous binding can by achieved by setting an empty value for BIND_DN and BIND_PASSWORD.

[2] The scope defines the following behaviors:

  • base: Limits the scope to a single object defined by the associated DN.
  • one: Searches all objects within the associated DN.
  • sub: Searches all objects and sub-objects within the associated DN.

[3] If GROUP_DN is specified, the user's role will always be updated on authentication to a matching group configured in AD, or fallback to the DEFAULT_ROLE_ID.

Example: LDAP

AUTH_PROVIDERS="ldap"

AUTH_LDAP_DRIVER="ldap"
AUTH_LDAP_CLIENT_URL="ldap://ldap.directus.io"
AUTH_LDAP_BIND_DN="CN=Bind User,OU=Users,DC=ldap,DC=directus,DC=io"
AUTH_LDAP_BIND_PASSWORD="p455w0rd"
AUTH_LDAP_USER_DN="OU=Users,DC=ldap,DC=directus,DC=io"
AUTH_LDAP_GROUP_DN="OU=Groups,DC=ldap,DC=directus,DC=io"
AUTH_PROVIDERS="ldap"

AUTH_LDAP_DRIVER="ldap"
AUTH_LDAP_CLIENT_URL="ldap://ldap.directus.io"
AUTH_LDAP_BIND_DN="CN=Bind User,OU=Users,DC=ldap,DC=directus,DC=io"
AUTH_LDAP_BIND_PASSWORD="p455w0rd"
AUTH_LDAP_USER_DN="OU=Users,DC=ldap,DC=directus,DC=io"
AUTH_LDAP_GROUP_DN="OU=Groups,DC=ldap,DC=directus,DC=io"

SAML

SAML is an open-standard, XML-based authentication framework for authentication and authorization between two entities without a password.

  • Service provider (SP) agrees to trust the identity provider to authenticate users.

  • Identity provider (IdP) authenticates users and provides to service providers an authentication assertion that indicates a user has been authenticated.

VariableDescriptionDefault Value
AUTH_<PROVIDER>_SP_metadataString containing XML metadata for service provider--
AUTH_<PROVIDER>_IDP_metadataString containing XML metadata for identity provider--
AUTH_<PROVIDER>_ALLOW_PUBLIC_REGISTRATIONAutomatically create accounts for authenticating users.false
AUTH_<PROVIDER>_DEFAULT_ROLE_IDA Directus role ID to assign created users.--
AUTH_<PROVIDER>_IDENTIFIER_KEYUser profile identifier key [1]. Will default to EMAIL_KEY.--
AUTH_<PROVIDER>_EMAIL_KEYUser profile email key.email

[1] When authenticating, Directus will match the identifier value from the external user profile to a Directus users "External Identifier".

The SP_metadata and IDP_metadata variables should be set to the XML metadata provided by the service provider and identity provider respectively.

Example: Multiple Auth Providers

You can configure multiple providers for handling authentication in Directus. This allows for different options when logging in. To do this, provide a comma-separated list of provider names, and a config block for each provider:

AUTH_PROVIDERS="google,facebook"

AUTH_GOOGLE_DRIVER="openid"
AUTH_GOOGLE_CLIENT_ID="830d...29sd"
AUTH_GOOGLE_CLIENT_SECRET="la23...4k2l"
AUTH_GOOGLE_ISSUER_URL="https://accounts.google.com/.well-known/openid-configuration"
AUTH_GOOGLE_IDENTIFIER_KEY="email"
AUTH_GOOGLE_ICON="google"
AUTH_GOOGLE_LABEL="Google"

AUTH_FACEBOOK_DRIVER="oauth2"
AUTH_FACEBOOK_CLIENT_ID="830d...29sd"
AUTH_FACEBOOK_CLIENT_SECRET="jd8x...685z"

FLOWS_RUN_SCRIPT_MAX_MEMORYThe maximum amount of memory the 'Run Script'-Operation can allocate in megabytes. A minimum of 8MB is required.32
FLOWS_RUN_SCRIPT_TIMEOUTThe maximum duration the 'Run Script'-Operation can run for in milliseconds.10000

Usage in Flows Run Script Operation

Allowed environment variables can be accessed through the $env within the passed data or through process.env.

js
const publicUrl = data['$env']['PUBLIC_URL'];
// OR
const publicUrl = data.$env.PUBLIC_URL;
// OR
const publicUrl = process.env.PUBLIC_URL;
const publicUrl = data['$env']['PUBLIC_URL'];
// OR
const publicUrl = data.$env.PUBLIC_URL;
// OR
const publicUrl = process.env.PUBLIC_URL;

Extensions

VariableDescriptionDefault Value
EXTENSIONS_PATH[1]Path to your local extensions folder../extensions
EXTENSIONS_MUST_LOADExit the server when any API extension fails to load.false
EXTENSIONS_AUTO_RELOAD[2]Automatically reload extensions when they have changed.false
EXTENSIONS_CACHE_TTL[3]How long custom app Extensions get cached by browsers.--
EXTENSIONS_LOCATION[4]What configured storage location to use for extensions.--

[1] If EXTENSIONS_LOCATION is configured, this is the path to the extensions folder within the selected storage location.

[2] EXTENSIONS_AUTO_RELOAD will not work when the EXTENSION_LOCATION environment variable is set.

[3] The EXTENSIONS_CACHE_TTL environment variable controls for how long custom app extensions (e.t., interface, display, layout, module, panel) are cached by browsers. Caching can speed-up the loading of the app as the code for the extensions doesn't need to be re-fetched from the server on each app reload. On the other hand, this means that code changes to app extensions won't be taken into account by the browser until EXTENSIONS_CACHE_TTL has expired. By default, extensions are not cached. The input data type for this environment variable is the same as CACHE_TTL.

[4] By default extensions are loaded from the local file system. EXTENSIONS_LOCATION can be used to load extensions from a storage location instead. Under the hood, they are synced into a local directory within TEMP_PATH and then loaded from there.
