Environment Variables and Configuration

Last updated: 14 minutes read.

To configure the Tyk Enterprise Developer Portal, you can use either a config file or environment variables. The below table provides reference to all options available to you when configuring the portal.

Portal settings

This section explains the general portal settings, including which port it will be listening on, how often it should synchronize API Products and plans with the Tyk Dashboard, and so on. Most of these settings are optional, except for the PORTAL_LICENSEKEY. If you don’t specify these settings, the default values will be used. However, you can leverage the settings below to customize the deployment of your portal.

Sample storage setting section via config file

{
  "HostPort": 3001,
  "RefreshInterval": 10,
  "LicenseKey": "your-license-key",
  "Theming": {
    "Theme": "default",
    "Path": "./themes"
  },
  "ProductDocRenderer": "stoplight",
  "LogLevel": "debug",
  "LogFormat": "dev",
  "TLSConfig": {
    "Enable": true,
    "InsecureSkipVerify": true,
    "Certificates": [
      {
        "Name": "localhost",
        "CertFile": "portal.crt",
        "KeyFile": "portal.key"
      }
    ],
    "MinVersion": "772"
  },
  "PortalAPISecret": "your-portal-api-secret"
}

Sample storage setting section via environment variables

PORTAL_HOSTPORT=3001
PORTAL_REFRESHINTERVAL=10
PORTAL_LICENSEKEY=your-license-key
PORTAL_THEMING_THEME=default
PORTAL_THEMING_PATH=./themes
PORTAL_DOCRENDERER=stoplight
PORTAL_LOG_LEVEL=debug
PORTAL_LOG_FORMAT=dev
PORTAL_TLS_ENABLE=true
PORTAL_TLS_INSECURE_SKIP_VERIFY=true
PORTAL_TLS_CERTIFICATES = '[{"Name": "localhost","CertFile": "portal.crt","KeyFile": "portal.key"}]'
PORTAL_API_SECRET=your-portal-api-secret

PORTAL_HOSTPORT

Config file: HostPort
Type: int
Description: The port on which the portal will run inside the container. Not required. If it is not specified, the default value is 3001.

PORTAL_REFRESHINTERVAL

Config file: RefreshInterval
Type: int
Description: How the portal will synchronise API Products and plans with the Tyk Dashboard. The value is specified in minutes. Not required. If it is not specified, the default value is 10.

PORTAL_LICENSEKEY

Config file: LicenseKey
Type: string
Description: A license key that Tyk provides. Required to start the portal.

PORTAL_THEMING_THEME

Config file: Theming.Theme
Type: string
Description: The name of a theme the portal should use after the start-up. You can change this later via the Themes UI. It’s not required to specify as the portal comes with only one theme named default, therefore, PORTAL_THEMING_THEME defaults default. However, if you already created a theme and want the portal to use when it’s starts for the first time, then you can use this setting to achieve that.

PORTAL_THEMING_PATH

Config file: Theming.Path
Type: string
Description: Defines a folder where themes are located. Depending on the storage type that you use, you can specify either a relative or an absolute path:

  • If you use the fs storage type, you can specify both a relative path (e.g., ./themes) and an absolute path (e.g., /themes)
  • If you use the s3 or db storage type, however, you can only use an absolute path (e.g., /themes).

The default value for this variable is ./themes, so it’s important to redefine it if you plan to use the s3 or db storage types.

PORTAL_THEMING_DISABLE_UPLOAD

Config file: Theming.DisableUpload
Type: boolean
Description: Disables uploading theme via the UI. The default value is false.

PORTAL_MAX_UPLOAD_SIZE

Config file: MaxUploadSize
Type: int
Description: Defines the maximum size in bytes of a theme file that can be uploaded via the UI. The default value is 33554432 bytes (32 mb).

Please note that the size of individual files should not exceed 5 MB. If the size of any individual file in a theme exceeds 5 MB, the theme will not be uploaded, even if the total size of all files is less than PORTAL_MAX_UPLOAD_SIZE.

PORTAL_DOCRENDERER

Config file: ProductDocRenderer
Type: string
Options:

  • stoplight to use Stoplight as a documentation renderer;
  • redoc to use Redoc as a documentation renderer.

Description: Use this setting to specify which OAS documentation renderer to use to render Open API Specification. Not required. If it is not specified, the default value is stoplight.

PORTAL_DCR_LOG_ENABLED

Config file: DCRLogEnabled
Type: boolean
Description: When enabled, the portal will print raw responses from OAuth2.0 Identity Provider for the DCR flow. Raw responses from the Identity Providers may contain sensitive information, therefore we recommend enabling this option only for debugging purposes. Available options are:

  • true for enabling the detailed logs;
  • false for disabling the detailed logs. The default value is false.

Audit log settings

This section explains how to configure the audit log in the portal. When the audit log is enabled, each admins’ action will leave a trace in the portal.log file located at in the directory specified by the PORTAL_AUDIT_LOG_ENABLE setting.

PORTAL_AUDIT_LOG_ENABLE

Config file: AuditLog.Enable
Type: boolean
Description: Enables the audit log capability. The default value is false.

PORTAL_AUDIT_LOG_PATH

Config file: AuditLog.Path
Type: string
Description: Path to a directory with the audit log file. When audit log is enabled, the portal will create a file called portal.log in that directory. All admin actions will be reflected in that file.

Session management

This section explains how to configure session management for the portal. Using the settings below, you can configure:

  • Name of the portal’s session cookie.
  • Various aspects of cookie security, including: should it be sent using an TLS-encrypted connection and is it accessible by Javascript API on the client-side?
  • Cookie encryption key.
  • Cookie lifetime.

PORTAL_SESSION_NAME

Config file: Session.Name
Type: string
Description: Name of the portal’s cookie. Default value is portal-session.

PORTAL_SESSION_SECURE

Config file: Session.Secure
Type: boolean
Description: Controls whether the portal adds the Secure attribute to the Set-Cookie header in all responses from the portal’s backend, except for the admin APIs. It’s important to note that if the connection between the portal and the browser is not secured with TLS, the browser will ignore the Secure attribute. We recommend enabling TLS and setting this attribute to true for all production environments. Default value is false.

PORTAL_SESSION_HTTPONLY

Config file: Session.HttpOnly
Type: boolean
Description: Controls whether the portal adds the HttpOnly attribute to the Set-Cookie header in all responses from the portal’s backend, except for the admin APIs. This cookie attribute controls if the cookie is only accessible at the server and not by Javascript on the client side. This is a security measure to prevent XSS attacks.

We recommend setting it to true in production environments. The default value is true.

PORTAL_SESSION_SAMESITE

Config file: Session.SameSite
Type: string
Description: Controls the value of the SameSite attribute for the portal’s cookie. The portal adds the SameStie attribute with the value specified in PORTAL_SESSION_SAMESITE to the Set-Cookie header in all responses from the portal’s backend, except for the admin APIs. Available options are:

  • None;
  • Lax;
  • Strict.

The default value is Strict. If the value specified in the PORTAL_SESSION_SAMESITE setting does not match any of the above-mentioned options, it defaults to Strict.

PORTAL_SESSION_KEY

Config file: Session.Key
Type: string
Description: The cookie encryption key. The default value is a random 32-bytes string.

PORTAL_SESSION_LIFETIME

Config file: Session.LifeTime
Type: int
Description: The lifetime of the portal’s session in seconds. The default value is 604800 seconds (7 days).

PORTAL_SESSION_IDLE_TIMEOUT

Config file: Session.IdleTimeout
Type: int
Description: The duration in seconds before a portal session is considered idle. A session is deemed idle when there is no user activity, such as clicks, navigation, or input. Once the idle timeout is reached, the session will expire, requiring the user to log in again. The default value is 3600 seconds (1 hour).

PORTAL_ENABLE_HTTP_PROFILER

Config file: EnableHttpProfiler
Type: boolean
Description: Enables debugging of the portal by exposing the Golang profiling information at /debug/pprof/. The default value is false.

Profiling

We recommend using the profiler only in non-production environments. Be sure to disable it in production by setting PORTAL_ENABLE_HTTP_PROFILER to false.
