Configuration

In this section, the configuration of the http data plane is explained. Configuration is used based on a config.yaml file which should be placed in the apps/backend folder. This config.yaml file is loaded when booting the application. The values get type checked, and it gives a clear error message if there is a configuration field missing or provided incorrectly. Next to the config.yaml file, you can also set environment variables. These override the values that are listed in the config.yaml file.

Databases

By default, the development database is sqlite. We use postgres databases for production type instances of the http data planes.

Authentication

Authentication for frontend services can be done via OAuth. This helps users who need to login to several components to authenticate themselves faster. The data plane is tested against the SSO Bridge, with an Helm chart provided alongside the Helm chart of the data plane, but other OAuth services should be usable (e.g. Keycloak, or hosted OAuth services).
