+
+
+DMaaP Information Producer Adapters (Kafka)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Configurable mediators to take information from DMaaP and Kafka and present it as a coordinated Information Producer.
+
+These mediators/adapters are generic information producers, which register themselves as information producers of defined information types in Information Coordination Service (ICS).
+The information types are defined in a configuration file.
+Information jobs defined using ICS then allow information consumers to retrieve data from DMaaP MR or Kafka topics (accessing the ICS API).
+
+There are two alternative implementations to allow Information Consumers to consume DMaaP or Kafka events as coordinated Information Jobs.
+
+Implementation:
+
+- Implementation in Java Spring (DMaaP Adapter), repo: *nonrtric/plt/dmaapadapter*, see :doc:`DMaaP Adapter documentation site <dmaapadapter:index>`.
+- Implementation in Go (DMaaP Mediator Producer), repo: *nonrtric/plt/dmaapmediatorproducer*, see :doc:`DMaaP Mediator Producer documentation site <dmaapmediatorproducer:index>`.

+
+Authentication Support (Keycloak)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The auth-token-fetch provides support for authentication.
+It is intended to be used as a sidecar and does the authentication procedure, gets and saves the access token
+in the local file system. This includes refresh of the token before it expires.
+This means that the service only needs to read the token from a file.
+
+It is tested using Keycloak as authentication provider.
+
+.. image:: ./AuthSupport.png
+ :width: 500pt
+
+So, a service just needs to read the token file and for instance insert it in the authorization header when using HTTP.
+The file needs to be re-read if it has been updated.
+
+The auth-token-fetch is configured by the following environment variables.
+
+* CERT_PATH - the file path of the cert to use for TSL, example: security/tls.crt
+* CERT_KEY_PATH - the file path of the private key file for the cert, example: "security/tls.key"
+* ROOT_CA_CERTS_PATH - the file path of the trust store.
+* CREDS_GRANT_TYPE - the grant_type used for authentication, example: client_credentials
+* CREDS_CLIENT_SECRET - the secret/private shared key used for authentication
+* CREDS_CLIENT_ID - the client id used for authentication
+* OUTPUT_FILE - the path where the fetched authorization token is stored, example: "/tmp/authToken.txt"
+* AUTH_SERVICE_URL - the URL to the authentication service (Keycloak)
+* REFRESH_MARGIN_SECONDS - how long in advance before the authorization token expires it is refreshed
+
