Add Environment Variables

Adding Environment Variables

To add extra environment variables to your containers, add the environment variable to an extraEnvs array on the service in your values.yml. These values can be provided directly or refer to secrets. The extraEnvs parameter is available for the rasa, rasax, eventService, and app services.

For example:

# rasa: Settings common for all Rasa containers
rasa:
  # other configured parameters
  # ...
  extraEnvs:
    - name: "SANIC_RESPONSE_TIMEOUT"
      value: 7200

# app (custom action server) specific settings
app:
  # other configured parameters
  # ...
  extraEnvs:
    - name: "SECRET_USERNAME"
      valueFrom:
        secretKeyRef:
          name: "login-secret"
          key: "username"

To add environment variables to the postgres, rabbit, or redis services, see Configuring the Subcharts.

Available Environment Variables

The environment variables below are configured by the Rasa Enterprise Helm chart and should only need to be configured directly in certain circumstances such as e.g. when using Oracle as a database. They are listed for reference and for cases where you do need to configure them directly.

Rasa Variables

These variables define the behavior of the Rasa containers and how the other services connect to them.

Variable	Default Value	Description
`RASA_TOKEN`	No default, must be defined in `.env`	Authentication token for the Rasa service. This is used by other services to communicate with Rasa.
`RASA_MODEL_PULL_INTERVAL`	`10`	How often to check for new models, in seconds
`RABBITMQ_QUEUE` (`rasa-production`)	`rasa_production_events`	Which Rabbit event queue to publish events to.
`DB_DATABASE` (`rasa-production`)	`tracker`	Which database table to use to access and store trackers.
`DB_DATABASE` (`rasa-worker`)	`worker_tracker`	Which database table to use to access and store trackers.
`POSTGRESQL_SCHEMA`	No default	PostgreSQL track store database schema to access. By default, Rasa accesses the `public` schema.
`RASA_MODEL_SERVER`	`http://rasa-x:5002/api/models/tags/production`	URL where to access stored models and store new ones.

Rasa Enterprise API Variables

These variables define the behavior of the Rasa Enterprise API and how the other services connect to it.

Variable	Default Value	Description
`RASA_X_HOST`	"http://rasa-x:5002"	The URL of the Rasa Enterprise services. This is used by other services to connect to the Rasa Enterprise API.
`RASA_X_TOKEN`	No default, must be defined in `.env`	The token used for authentication between other services and the Rasa Enterprise API.
`RASA_X_USERNAME` (only for Rasa Enterprise)	admin	If `RASA_X_PASSWORD` is specified then the user with this username will be created automatically after Rasa Enterprise is started for the first time.
`RASA_X_PASSWORD`	No default, must be defined in `.env` if you want user to be created	If specified, this user with username `RASA_X_USERNAME` will be created immediately after Rasa Enterprise is started for the first time.
`JWT_SECRET`	No default, must be defined in `.env`	Symmetric JWT token for authentication protection of the Rasa API server.
`RASA_USER_APP`	`"http://app:5055"`	URL of the custom action server.
`RASA_PRODUCTION_HOST`	`http://rasa-production:5005`	Host and port at which to find the rasa-production server.
`RASA_WORKER_HOST`	"http://rasa-worker:5005"	Host and port at which to find the rasa-worker server.
`RASA_WORKER_TOKEN`	Interpolated from `RASA_TOKEN`	Authentication token used to connect to the Rasa services.
`RASA_MODEL_DIR`	`/app/models`	The directory in which models are stored on the Rasa Enterprise container.
`RABBITMQ_QUEUE`	`rasa_production_events`	Which queue to read conversation events from.
`ROOT_URL`	`"/"`	Root URL for the frontend to check for resources. Use this if you are hosting your Rasa Enterprise instance on a subdirectory of a domain. No trailing slash.

note

Changing some of these variables requires changes in other containers; for example, if updating your endpoints path, you should also add the new path (relative from the app directory) to the start-up command of your Rasa containers with the --endpoints flag.

RabbitMQ Variables

These variables define the behavior of RabbitMQ and how the other services connect to it. More information about RabbitMQ can be found in the RabbitMQ docs.

Variable	Description
`RABBITMQ_HOST`	Hostname of the RabbitMQ instance.
`RABBITMQ_PORT`	Port of the RabbitMQ instance.
`RABBITMQ_USERNAME`	Username used by other services to access RabbitMQ.
`RABBITMQ_PASSWORD`	Password used by other services to access RabbitMQ.
`RABBITMQ_QUEUE`	Queue from which the event service should read messages.

DB Variables

These variables define the connection details for the Rasa Enterprise database / the Rasa Open Source tracker store.

Variable	Default Value	Description
`DB_HOST`	"db"	Hostname of the container hosting the PostgreSQL database.
`DB_PORT`	"5432"	Port used by other services to access the database.
`POSTGRESQL_USERNAME` (`DB_USER`)	"admin"	Username used by other services to access the database.
`POSTGRESQL_PASSWORD` (`DB_PASSWORD`)	No default, must be defined in `.env`	Password used by other services to access the database.
