Authentication Configuration

Introduction

The connector supports a wide array of authentication strategies which you can adjust in the connector's configuration.yaml file.

Basic Authentication

connection_settings:
  authentication:
    basic:
      username:
        env: PROMETHEUS_USERNAME
      password:
        env: PROMETHEUS_PASSWORD

HTTP Authorization

connection_settings:
  authentication:
    authorization:
      type:
        value: Bearer
      credentials:
        env: PROMETHEUS_AUTH_TOKEN

OAuth2

connection_settings:
  authentication:
    oauth2:
      token_url:
        value: http://example.com/oauth2/token
      client_id:
        env: PROMETHEUS_OAUTH2_CLIENT_ID
      client_secret:
        env: PROMETHEUS_OAUTH2_CLIENT_SECRET

Google Cloud

The configuration accepts either the Google application credentials JSON string or file path. If the object is empty the client automatically loads the credential file from the GOOGLE_APPLICATION_CREDENTIALS environment variable.

connection_settings:
  authentication:
    google:
      # credentials:
      #   env: GOOGLE_APPLICATION_CREDENTIALS_JSON
      # credentials_file:
      #   env: GOOGLE_APPLICATION_CREDENTIALS
