-Configuration Pusher
---------------------
-
-Once the SD-Fabric has been deployed to the Kubernetes, a special Kubernetes
-pod, config pusher will enter to a reconciliation loop to update both
-network configuration and component configuration to ONOS controller.
-
-Config pusher will read running state from ONOS controller and
-then update the ONOS with desired state if running state isn't same as desired state.
-
-.. image:: images/config-pusher.svg
-
-.. note::
-   We highly recommend using the Helm Chart to update the configuration instead of manually changing the ONOS unless you're working on debugging or testing.
-
-Config Pusher supports variety options to adjust its behavior and you can change it via Helm Chart's value file.
-
-Below is the default values of config pusher and please change it to meet your environment.
-
-
-.. code-block::
-
-      onos:
-        config:
-          reconcile_mode: true
-          reconcile_interval: 30s
-          image:
-            registry: ""
-            repository: opencord/onos-classic-helm-utils
-            tag: 0.1.0
-            pullPolicy: "IfNotPresent"
-          service_account_name: onos-config-loader
-          # NOTE that these values won't change the configuration in the ONOS container, they are only used in the script that loads the config
-          username: karaf
-          password: karaf
-          # netcfg: >
-          #  {}
-          # componentConfig:
-          #   "org.onosproject.provider.lldp.impl.LldpLinkProvider": >
-          #     {
-          #       "enabled": "false"
-          #     }

-* ``reconcile_mode``: If disable, config pusher will only update the configuration once, it's useful for debugging.
-* ``reconcile_interval``: The interval(seconds) config pusher used to perform reconciliation loop.
-* ``image``: About how to pull config pusher's container image, keep it default unless you have special requirement.
-
-  * ``registry``: If empty, the config pusher image will be downloaded from Docker Hub.
