Config Manager Agent
--------------------

Config Manager Agent is an EII service, that is responsible for the following:


* Puts the EII services configs to the EII config manager data store
* Additionally in PROD mode, generates the following:

  * Required config manager data store keys/certificates to interact with EII config manager data store like etcd and puts in the volume mounts to be shared with
    other EII services
  * Required messagebus keys for EII services communication

* Creates required provisioning folders with the right permissions needed for other EII services via volume mounts

The following diagram shows a high level flow of ``ConfigMgrAgent`` service .

.. note:: 
   Any EII service ``waits/restarts`` if the config manager data store client key and certificates are yet to be made available for the container.
   EII Certificates will be re-generated everytime the ConfigMgrAgent service brought up/restarted


 **Optional:** For capturing the data back from Etcd to a JSON file, run the etcd_capture.sh script. This can be achieved using the following command:

.. code-block:: sh

    docker exec -it ia_configmgr_agent ./scripts/etcd_capture.sh
