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.
