Standalone Authorizer configuration reference

Learn how to configure Standalone Authorizer to adjust its settings to your needs.

Configuring the Standalone Authorizer

The Standalone Authorizer can be configured with a file in YAML format, or via environment variables. To generate a template configuration file that is populated with default settings, you can use a Docker image and pipe the output to a configuration file:

docker run --rm docker.cloudentity.io/standalone-authorizer reference > reference_config.yaml

You can use the configuration reference as a basis for your customization. You can omit settings for which the default configuration is satisfactory, specifying only the required values, which are the client ID, client secret, and issuer URL parameters.

ACP_CLIENT_ID: {your_client_id}
ACP_CLIENT_SECRET: {your_client_secret}
ACP_ISSUER_URL: https://{tid}.us.authz.stage.cloudentity.io/{tid}/system

Environment variables can also be used to set these configuration values. The environment variable’s name are the uppercase version of the YAML name. For example, in the docker-compose.yml that you downloaded, you can set the ACP_CLIENT_ID via the environment variable ACP_CLIENT_ID:

      - HTTP_SERVER_PORT=9004


Note that nested YAML settings can be accessed by joining uppercased names with underscores, as shown in the example above, where the HTTP_SERVER_PORT=9004 parameter is set.

To run the standalone authorizer with a configuration file, use the --config option to specify the YAML file with your configuration. For example, assuming that you have created a standalone_config.yaml file in your current directory your docker run command would look like the following:

docker run --rm --volume `pwd`:/config:ro docker.cloudentity.io/standalone-authorizer --config /config/standalone_config.yaml
