Environment variables

Environment variables are key value pairs that are used to configure how your Rafiki instance will run within your infrastructure and integrate with your systems.

Each environment variable name is uppercase, followed by an equal sign and the value of the variable.

Environment variable example

WEBHOOKS_URL=http://my-business/webhooks

The environment variable in the example above specifies the HTTP endpoint at which you want your Rafiki instance to send you notifications of webhook events.

To run Rafiki you must set the environment variables for the backend, auth and frontend services where listed as required below.

Caution

If you are running Rafiki via Docker, you must update the variables in the docker-compose.yml files of the respective services.

If you are running Rafiki via Helm and Kubernetes, you must update the variables in the values.yaml file of the Helm chart template.
