+The CLAMP Control Loop Runtime
+##############################
+
+.. contents::
+    :depth: 3
+
+
+This article explains how CLAMP Control Loop Runtime is implemented.
+
+Terminology
+***********
+- Broadcast message: a message for all participants (participantId=null and participantType=null)
+- Message to a participant: a message only for a participant (participantId and participantType properly filled)
+- ThreadPoolExecutor: ThreadPoolExecutor executes the given task, into SupervisionAspect class is configured to execute tasks in ordered manner, one by one
+- Spring Scheduling: into SupervisionAspect class, the @Scheduled annotation invokes "schedule()" method every "runtime.participantParameters.heartBeatMs" milliseconds with a fixed delay
+- MessageIntercept: "@MessageIntercept" annotation is used into SupervisionHandler class to intercept "handleParticipantMessage" method calls using spring aspect oriented programming
+- GUI: graphical user interface, Postman or a Front-End Application

+
+StartPhase
+**********
+The startPhase is particularly important in control loop update and control loop state changes because sometime the user wishes to control the order in which the state changes in Control Loop Elements in a control loop.
+
+How to define StartPhase
+++++++++++++++++++++++++
+StartPhase is defined as shown below in the Definition of TOSCA fundamental Control Loop Types yaml file.
+
+.. code-block:: YAML
+
+  startPhase:
+    type: integer
+    required: false
+    constraints:
+    - greater-or-equal: 0
+    description: A value indicating the start phase in which this control loop element will be started, the
+                 first start phase is zero. Control Loop Elements are started in their start_phase order and stopped
+                 in reverse start phase order. Control Loop Elements with the same start phase are started and
+                 stopped simultaneously
+    metadata:
+      common: true
+
+The "common: true" value in the metadata of the startPhase property identifies that property as being a common property.
+This property will be set on the CLAMP GUI during control loop commissioning.
+Example where it could be used:
+
+.. code-block:: YAML
+
+  org.onap.domain.database.Http_PMSHMicroserviceControlLoopElement:
+    # Consul http config for PMSH.
+    version: 1.2.3
+    type: org.onap.policy.clamp.controlloop.HttpControlLoopElement
+    type_version: 1.0.1
+    description: Control loop element for the http requests of PMSH microservice
+    properties:
+      provider: ONAP
+      participant_id:
+        name: HttpParticipant0
+        version: 1.0.0
+      participantType:
+        name: org.onap.k8s.controlloop.HttpControlLoopParticipant
+        version: 2.3.4
+      uninitializedToPassiveTimeout: 180
+      startPhase: 1
+
+How StartPhase works
+++++++++++++++++++++
+In state changes from UNITITIALISED → PASSIVE, control loop elements are started in increasing order of their startPhase.
+
+Example with Http_PMSHMicroserviceControlLoopElement with startPhase to 1 and PMSH_K8SMicroserviceControlLoopElement with startPhase to 0
+
+- CL-runtime sends a broadcast CONTROL_LOOP_UPDATE message to all participants with startPhase = 0
+- participant receives the CONTROL_LOOP_UPDATE message and runs to PASSIVE state (only CL elements defined as startPhase = 0)
+- CL-runtime receives CONTROL_LOOP_UPDATE_ACT messages from participants and set the state (from the CL element of the message) to PASSIVE
+- CL-runtime calculates that all CL elements with startPhase = 0 are set to proper state and sends a broadcast CONTROL_LOOP_UPDATE message with startPhase = 1
+- participant receives the CONTROL_LOOP_UPDATE message and runs to PASSIVE state (only CL elements defined as startPhase = 1)
+- CL-runtime calculates that all CL elements are set to proper state and set CL to PASSIVE
+
+In that scenario the message CONTROL_LOOP_UPDATE has been sent two times.
+
+Design of managing messages
+***************************
+
+PARTICIPANT_REGISTER
+++++++++++++++++++++
+- A participant starts and send a PARTICIPANT_REGISTER message
+- ParticipantRegisterListener collects the message from DMaap
+- if not present, it saves participant reference with status UNKNOWN to DB
+- if is present a Control Loop Type, it triggers the execution to send a PARTICIPANT_UPDATE message to the participant registered (message of Priming)
+- the message is built by ParticipantUpdatePublisher using Tosca Service Template data (to fill the list of ParticipantDefinition)
+- It triggers the execution to send a PARTICIPANT_REGISTER_ACK message to the participant registered
+- MessageIntercept intercepts that event, if PARTICIPANT_UPDATE message has been sent, it will be add a task to handle PARTICIPANT_REGISTER in SupervisionScanner
+- SupervisionScanner starts the monitoring for participantUpdate
+
+PARTICIPANT_UPDATE_ACK
+++++++++++++++++++++++
+- A participant sends PARTICIPANT_UPDATE_ACK message in response to a PARTICIPANT_UPDATE message
+- ParticipantUpdateAckListener collects the message from DMaap
+- MessageIntercept intercepts that event and adds a task to handle PARTICIPANT_UPDATE_ACK in SupervisionScanner
+- SupervisionScanner removes the monitoring for participantUpdate
+- It updates the status of the participant to DB
+
+PARTICIPANT_STATUS
+++++++++++++++++++
+- A participant sends a scheduled PARTICIPANT_STATUS message
+- ParticipantStatusListener collects the message from DMaap
+- MessageIntercept intercepts that event and adds a task to handle PARTICIPANT_STATUS in SupervisionScanner
+- SupervisionScanner clears and starts the monitoring for participantStatus
+
+CONTROLLOOP_UPDATE_ACK
+++++++++++++++++++++++
+- A participant sends CONTROLLOOP_UPDATE_ACK message in response to a CONTROLLOOP_UPDATE  message. It will send a CONTROLLOOP_UPDATE_ACK - for each CL-elements moved to the ordered state as indicated by the CONTROLLOOP_UPDATE
+- ControlLoopUpdateAckListener collects the message from DMaap
+- It checks the status of all control loop elements and checks if the control loop is primed
+- It updates the CL to DB if it is changed
+- MessageIntercept intercepts that event and adds a task to handle a monitoring execution in SupervisionScanner
+
+CONTROLLOOP_STATECHANGE_ACK
++++++++++++++++++++++++++++
+Design of a CONTROLLOOP_STATECHANGE_ACK is similar to the design for CONTROLLOOP_UPDATE_ACK
+
+Design of monitoring execution in SupervisionScanner
+****************************************************
+Monitoring is designed to process the follow operations:
+
+- to determine the next startPhase in a CONTROLLOOP_UPDATE message
+- to update CL state: in a scenario that "ControlLoop.state" is in a kind of transitional state (example UNINITIALISED2PASSIVE), if all  - CL-elements are moved properly to the specific state, the "ControlLoop.state" will be updated to that and saved to DB
+- to retry CONTROLLOOP_UPDATE/CONTROL_LOOP_STATE_CHANGE messages. if there is a CL Element not in the proper state, it will retry a broadcast message
+- to retry PARTICIPANT_UPDATE message to the participant in a scenario that CL-runtime do not receive PARTICIPANT_UPDATE_ACT from it
+- to send PARTICIPANT_STATUS_REQ to the participant in a scenario that CL-runtime do not receive PARTICIPANT_STATUS from it
+
+The solution Design of retry, timeout, and reporting for all Participant message dialogues are implemented into the monitoring execution.
+
+- Spring Scheduling inserts the task to monitor retry execution into ThreadPoolExecutor
+- ThreadPoolExecutor executes the task
+- a message will be retry if CL-runtime do no receive Act message before MaxWaitMs milliseconds
+
+Design of Exception handling
+****************************
+GlobalControllerExceptionHandler
+++++++++++++++++++++++++++++++++
+If error occurred during the Rest Api call, CL-runtime responses with a proper status error code and a JSON message error.
+This class is implemented to intercept and handle ControlLoopException, PfModelException and PfModelRuntimeException if they are thrown during the Rest Ali calls.
+All of those classes must implement ErrorResponseInfo that contains message error and status response code.
+So the Exception is converted in JSON message.
+
+RuntimeErrorController
+++++++++++++++++++++++
+If wrong end-point is called or an Exception not intercepted by GlobalControllerExceptionHandler, CL-runtime responses with a proper status error code and a JSON message error.
+This class is implemented to redirect the standard Web error page to a JSON message error.
+Typically that happen when a wrong end-point is called, but also could be happen for not authorized call, or any other Exception not intercepted by GlobalControllerExceptionHandler.
+
+Handle version and "X-ONAP-RequestID"
+*************************************
+RequestResponseLoggingFilter class handles version and "X-ONAP-RequestID" during a Rest-Api call; it works as a filter, so intercepts the Rest-Api and adds to the header those information.
+
+Media Type Support
+******************
+CL-runtime Rest Api supports **application/json**, **application/yaml** and **text/plain** Media Types. The configuration is implemented in CoderHttpMesageConverter.
+
+application/json
+++++++++++++++++
+JSON format is a standard for Rest Api. For the conversion from JSON to Object and vice-versa will be used **org.onap.policy.common.utils.coder.StandardCoder**.
+
+application/yaml
+++++++++++++++++
+YAML format is a standard for Control Loop Type Definition. For the conversion from YAML to Object and vice-versa will be used **org.onap.policy.common.utils.coder.StandardYamlCoder**.
+
+text/plain
+++++++++++
+Text format is used by Prometheus. For the conversion from Object to String  will be used **StringHttpMessageConverter**.

+The Policy GUI for Control Loops
+********************************
+
+.. contents::
+    :depth: 4
+
+.. _Introduction:
+
+1. Introduction
+###############
+The Policy GUI for Control Loops is designed to provide a user the ability to interact with the Control Loop Runtime to perform several actions. The actual technical design of the Control Loop Runtime is detailed in :ref:`clamp-controlloop-runtime`. All of the endpoints and the purpose for accessing those endpoints is discussed there. In the current release of the GUI, the main purposes are to perform the below:
+
+- Commission new Tosca Service Templates.
+- Editing Common Properties.
+- Priming/De-priming Control Loop Definitions.
+- Decommission existing Tosca Service Templates.
+- Create new instances of Control Loops.
+- Change the state of the Control Loops.
+- Delete Control Loops.
+
+These functions can be carried out by accessing the Controlloop Runtime alone but this should not be required for a typical user to access the system. That is why the Controlloop GUI is required. The remainder of this document will be split into 2 main sections. The first section will show the overall architecture of ControlLoop with the GUI included, so that the reader can see where it fits in to the system. Then the section will outline the individual components required for a working GUI and outline how GUI interacts with these components and why. The final section has a diagram to show the flow of typical operations from the GUI, all the way down to the participants.
+
+2. GUI-focussed System Architecture
+###################################
+An architectural/functional diagram has bee provided in below. This does not show details of the other components involved in the GUI functionality. Most of the detail is provided for the GUI itself.
+
+    .. image:: ../images/gui/GUI-Architecture.png
+        :align: center
+
+The remainder of this section outlines the different elements that comprise the architecture of the GUI and how the different elements connect to one another.
+
+2.1 Policy CLAMP GUI
+--------------------
+
+2.1.1 CLAMP GUI
+================
+The original Clamp project used the GUI to connect to various onap services, including policy api, policy pap, dcae, sdc and cds. Connection to all of these services is managed by the Camel Exchange present in the section :ref:`Policy Clamp Backend`.
+
+Class-based react components are used to render the different pages related to functionality around
+
+- Creating loop instances from existing templates that have been distributed by SDC.
+- Deploying/Undeploying policies to the policy framework.
+- Deploying/Undeploying microservices to the policy framework.
+- Deleting Instances.
+
+Although this GUI deploys microservices, it is a completely different paradigm to the new ControlLoop participant-based deployment of services. Details of the CLAMP GUI are provided in :ref:`clamp-builtin-label`
+
+2.1.2 Controlloop GUI
+=====================
+
+The current control loop GUI is an extension of the previously created GUI for the Clamp project. The Clamp project used the CLAMP GUI to connect to various onap services, including policy api, policy pap, dcae, sdc and cds. Although the current control loop project builds upon this GUI, it does not rely on these connected services. Instead, the ControlLoop GUI connects to the ControlLoop Runtime only. The ControlLoop Runtime then communicates with the database and all the ControlLoop participants (indirectly) over DMAAP.
+
+The CLAMP GUI was originally housed in the clamp repository but for the Istanbul release, it has been moved to the policy/gui repo. There are 3 different GUIs within this repository - clamp-gui (and ControlLoop gui) code is housed under the "gui-clamp" directory and the majority of development takes place within the "gui-clamp/ui-react" directory.
+
+The original CLAMP GUI was created using the React framework, which is a light-weight framework that promotes use of component-based architecture. Previously, a class-based style was adopted to create the Clamp components. It was decided that ControlLoop would opt for the more concise functional style of components. This architecture style allows for the logical separation of functionality into different components and minimizes bloat. As you can see from the image, there is a "ControlLoop" directory under components where all of our ControlLoop components are housed.
+
+    .. image:: ../images/gui/ComponentFileStructure.png
+
+Any code that is directly involved in communication with outside services like Rest Apis is under "ui-react/src/api". The "fetch" Javascript library is used for these calls. The ControlLoop service communicates with just the ControlLoop Runtime Rest Api, so all of the communication code is within "ui-react/src/api/ControlLoopService.js".
+
+2.1.2.1 Services
+""""""""""""""""
+The ControlLoop GUI is designed to be service-centric. This means that the code involved in rendering and manipulating data is housed in a different place to the code responsible for communication with outside services. The ControlLoop related services are those responsible for making calls to the commissioning and instantiation endpoints in the ControlLoop Runtime. Another detail to note is that both the ControlLoop and CLAMP GUI use a proxy to forward requests to the policy clamp backend. Any URLs called by the frontend that contain the path "restservices/clds/v2/" are forwarded to the backend. Services are detailed below:
+
+- A commissioning call is provided for contacting the commissioning API to commission a tosca service template.
+- A decommissioning call is provided for calling the decommissioning endpoint.
+- A call to retrieve the tosca service template from the runtime is provided. This is useful for carrying out manipulations on the template, such as editing the common properties.
+- A call to get the common or instance properties is provided. This is used to provide the user an opportunity to edit these properties.
+- Calls to allow creation and deletion of an instance are provided
+- Calls to change the state of and instance are provided.
+- Calls to get the current state and ordered state of the instances, effectively monitoring.
+
+These services provide the data and communication functionality to allow the user to perform all of the actions mentioned in the :ref:`Introduction`.
+
+2.1.2.2 Components
+""""""""""""""""""
+The components in the architecture image reflect those rendered elements that are presented to the user. Each element is designed to be as user-friendly as possible, providing the user with clean uncluttered information. Note that all of these components relate to and were designed around specific system dialogues that are present in :ref:`system-level-label`.
+
+- For commissioning, the user is provided with a simple file upload. This is something the user will have seen many times before and is self explanatory.
+- For the edit of common properties, a JSON editor is used to present whatever common properties that are present in the service template to the user in as simple a way possible. The user can then edit, save and recommission.
+- A link is provided to manage the tosca service template, where the user can view the file that has been uploaded in JSON format and optionally delete it.
+- Several functions are exposed to the user in the "Manage Instances" modal. From there they can trigger, creation of an instance, view monitoring information, delete an instance and change the state.
+- Before an instance is created, the user is provided an opportunity to edit the instance properties. That is, those properties that have not been marked as common.
+- The user can change the state of the instance by using the "Change" button on the "Manage Instances" modal. This is effectively where the user can deploy and undeploy an instance.
+- Priming and De-priming take place as a result of the action of commissioning and decommissioning a tosca service template. A more complete discussion of priming and de-priming is found here :ref:`controlloop-participant-protocol-label`.
+- As part of the "Manage Instances" modal, we can monitor the state of the instances in 2 ways. The color of the instance highlight in the table indicates the state (grey - uninitialised, passive - yellow, green - running). Also, there is a monitoring button that allows use to view the individual elements' state.
+
+.. _Policy Clamp Backend:
+
+2.2 Policy Clamp Backend
+------------------------
+The only Rest API that the ControlLoop frontend (and CLAMP frontend) communicates with directly is the Clamp backend. The backend is written in the Springboot framework and has many functions. In this document, we will only discuss the ControlLoop related functionality. Further description of non-ControlLoop Clamp and its' architecture can be found in :ref:`clamp-builtin-label`. The backend receives the calls from the frontend and forwards the requests to other relevant APIs. In the case of the ControlLoop project, the only Rest API that it currently requires communication with is the runtime ControlLoop API. ControlLoop adopts the same "request forwarding" method as the non-ControlLoop elements in the CLAMP GUI. This forwarding is performed by Apache Camel Exchanges, which are specified in XML and can be found in the directory shown below in the Clamp repository.
+
+    .. image:: ../images/gui/CamelDirectory.png
+
+The Rest Endpoints for the GUI to call are defined in "clamp-api-v2.xml" and all of the runtime ControlLoop rest endpoints that GUI requests are forwarded to are defined in ControlLoop-flows.xml. If an Endpoint is added to the runtime ControlLoop component, or some other component you wish the GUI to communicate with, a Camel XML exchange must be defined for it here.
+
+2.3 ControlLoop Runtime
+-----------------------
+This is where all of the endpoints for operations on ControlLoops are defined thus far. Commissioning, decommissioning, control loop creation, control loop state change and control loop deletion are all performed here. The component is written using the Springboot framework and all of the code is housed in the runtime-ControlLoop directory shown below:
+
+    .. image:: ../images/gui/RuntimeControlloopDirectory.png
+
+The rest endpoints are split over two main classes; CommissioningController.java and InstantiationController.java. There are also some rest endpoints defined in the MonitoringQueryController. These classes have minimal business logic defined in them and delegate these operations to other classes within the controlloop.runtime package. The ControlLoop Runtime write all data received on its' endpoints regarding commissioning and instantiation to its; database, where it can be easily accessed later by the UI.
+
+The Runtime also communicates with the participants over DMAAP. Commissioning a control loop definition writes it to the database but also triggers priming of the definitions over DMAAP. The participants then receive those definitions and hold them in memory. Similarly, upon decommissioning, a message is sent over DMAAP to the participants to trigger de-priming.
+
+Using DMAAP, the Runtime can send; updates to the control loop definitions, change the state of control loops, receive information about participants, receive state information about control loops and effectively supervise the control loops. This data is then made available via Rest APIs that can be queried by the frontend. This is how the GUI can perform monitoring operations.
+
+More detail on the design of the Runtime ControlLoop can be found in :ref:`clamp-controlloop-runtime`.
+
+2.4 DMAAP
+---------
+DMAAP is comonent that provides data movement services that transports and processes data from any source to any target.  It provides the capability to:
+- Support the transfer of messages between ONAP components, as well as to other components
+- Support the transfer of data between ONAP components as well as to other components.
+- Data Filtering capabilities
+- Data Processing capabilities
+- Data routing (file based transport)
+- Message routing (event based transport)
+- Batch and event based processing
+
+Specifically, regarding the communication between the ControlLoop Runtime and the ControlLoop Participants, both components publish and subscribe to a specific topic, over which data and updates from the participants and control loops are sent. The ControlLoop Runtime updates the current statuses sent from the participants in the database and makes them available the the GUI over the Rest API.
+
+2.5 The Participants
+--------------------
+The purpose of the ControlLoop participants is to communicate with different services on behalf of the ControlLoop Runtime. As there are potentially many different services that a ControlLoop might require access to, there can be many different participants. For example, the kubernetes participant is responsible for carrying out operations on a kubernetes cluster with helm. As of the time of writing, there are three participants defined for the ControlLoop project; the policy participant, the kubernetes participant and the http participant. The participants are housed in the directory shown below in the policy-clamp repo.
+
+    .. image:: ../images/gui/ParticipantsDirectory.png
+
+The participants communicate with the Runtime over DMAAP. Tosca service template specifications, ControlLoop updates and state changes are shared with the participants via messages from runtime ControlLoop through the topic "POLICY-CLRUNTIME-PARTICIPANT".
+
+3. GUI Sample Flows
+###################
+The primary flows from the GUI to the backend, through DMAAP and the participants are shown in the diagram below. This diagram just serves as an illustration of the scenarios that the user will experience in the GUI. You can see factually complete dialogues in :ref:`system-level-label`.

+
+HTTP Participant
+################
+
+The CLAMP HTTP participant receives configuration information from the CLAMP runtime,
+maps the configuration information to a REST URL, and makes a REST call on the URL.
+Typically the HTTP Participant is used with another participant such as the
+:ref:`Kubernetes Participant <clamp-controlloop-k8s-participant>`, which brings up
+the microservice that runs a REST server. Once the microservice is up, the HTTP
+participant can be used to configure the microservice over its REST interface.Of course,
+the HTTP participant works towards any REST service, it is not restricted to REST
+services started by participants.
+
+
+.. image:: ../../images/participants/http-participant.png
+
+
+The HTTP participant runs a Control Loop Element to handle the REST dialogues for a
+particular application domain. The REST dialogues are whatever REST calls that are
+required to implement the functionality for the application domain.
+
+The HTTP participant allows the REST dialogues for a Control Loop to be managed. A
+particular Control Loop may require many *things* to be configured and managed and this
+may require many REST dialogues to achieve.
+
+When a control loop is initialized, the HTTP participant starts a HTTP Control Loop
+element for the control loop. It reads the configuration information sent from the
+Control Loop Runtime runs a HTTP client to talk to the REST endpoint that is receiving
+the REST requests. A HTTP participant can simultaneously manage HTTP Control Loop
+Elements towards multiple REST endpoints, as shown in the diagram above where the HTTP
+participant is running two HTTP Control Loop Elements, one for Control Loop A and one for
+Control Loop B.
+
+Configuring a Control Loop Element on the HTTP participant for a Control Loop
+-----------------------------------------------------------------------------
+A *Configuration Entity* describes a concept that is managed by the HTTP participant. A
+Configuration Entity can be created, Read, Updated, and Deleted (CRUD). The user defines
+the Configuration Entities that it wants its HTTP Control Loop Element to manage and
+provides a sequence of parameterized REST commands to Create, Read, Update, and Delete
+each Configuration Entity.
+
+Sample tosca template defining a http participant and a control loop element for a control loop. :download:`click here <tosca/tosca-http-participant.yml>`
+
+The user configures the following properties in the TOSCA for the HTTP participant:
+
+.. list-table::
+   :widths: 15 10 50
+   :header-rows: 1
+
+   * - Property
+     - Type
+     - Description
+   * - baseUrl
+     - URL

+
+Http participant Interactions:
+------------------------------
+The http participant interacts with Control Loop Runtime on the northbound via DMaap. It interacts with any microservice on the southbound over http for configuration.
+
+The communication for the Control loop updates and state change requests are sent from the Control Loop Runtime to the participant via DMaap.
+The participant invokes the appropriate http endpoint of the microservice based on the received messages from the Control Loop Runtime.
+
+
+startPhase:
+-----------
+The http participant is often used along with :ref:`Kubernetes Participant <clamp-controlloop-k8s-participant>` to configure the microservice after the deployment.
+This requires the Control Loop Element of http participant to be started after the completion of deployment of the microservice. This can be achieved by adding the property `startPhase`
+in the Control Loop Element of http participant. Control Loop Runtime starts the elements based on the `startPhase` value defined in the Tosca. The default value of startPhase is taken as '0'
+which takes precedence over the Control Loop Elements with the startPhase value '1'. Http Control Loop Elements are defined with value '1' in order to start the Control Loop Element in the second phase.
+
+Http participant Workflow:
+--------------------------
+Once the participant is started, it sends a "REGISTER" event to the DMaap topic which is then consumed by the Control Loop Runtime to register this participant on the runtime database.
+The user can commission the tosca definitions from the Policy Gui to the Control Loop Runtime that further updates the participant with these definitions via DMaap.
+Once the control loop definitions are available in the runtime database, the Control Loop can be instantiated with the default state "UNINITIALISED" from the Policy Gui.
+
+When the state of the Control Loop is changed from "UNINITIALISED" to "PASSIVE" from the Policy Gui, the http participant receives the control loop state change event from the runtime and
+configures the microservice of the corresponding Control Loop Element over http.
+The configuration entity for a microservice is associated with each Control Loop Element for the http participant.
+The http participant holds the executed http requests information along with the responses received.
+
+The participant is used in a generic way to configure any entity over http and it does not hold the information about the microservice to unconfigure/revert the configurations when the
+state of Control Loop changes from "PASSIVE" to "UNINITIALISED".

+Kubernetes Participant
+######################
+
+The kubernetes participant receives a helm chart information from the CLAMP runtime and installs the helm chart in to the
+k8s cluster on the specified namespace. It can fetch the helm chart from remote helm repositories as well as from any of the repositories
+that are configured on the helm client. The participant acts as a wrapper around the helm client and creates the required
+resources in the k8s cluster.
+
+The kubernetes participant also exposes REST endpoints for onboarding, installing and uninstalling of helm charts from the
+local chart database which facilitates the user to also use this component as a standalone application for helm operations.
+
+In Istanbul version, the kubernetes participant supports the following methods of installation of helm charts.
+
+- Installation of helm charts from configured helm repositories and remote repositories passed via TOSCA in CLAMP.
+- Installation of helm charts from the local chart database via the participant's REST Api.
+
+Prerequisites for using Kubernetes participant in Istanbul version:
+-------------------------------------------------------------------
+
+- A running Kubernetes cluster.
+
+  Note:
+
+  - If the kubernetes participant is deployed outside the cluster , the config file of the k8s cluster needs to be copied to the `./kube` folder of kubernetes participant's home directory to make the participant work with the external cluster.
+
+  - If the participant needs additional permission to create resources on the cluster, cluster-admin role binding can be created for the service account of the participant with the below command.
+
+    Example: `kubectl create clusterrolebinding k8s-participant-admin-binding --clusterrole=cluster-admin --serviceaccount=<k8s participant service account>`
+
+
+.. image:: ../../images/participants/k8s-participant.png
+
+Defining a TOSCA CL definition for kubernetes participant:
+----------------------------------------------------------
+
+A *chart* parameter map describes the helm chart parameters in tosca template for a microservice that is used by the kubernetes participant for the deployment.
+A Control Loop element in TOSCA is mapped to the kubernetes participant and also holds the helm chart parameters for a microservice defined under the properties of the Control Loop Element.
+
+Sample tosca template defining a participant and a control loop element for a control loop. :download:`click here <tosca/tosca-k8s-participant.yml>`
+
+
+Configuring a Control Loop Element on the kubernetes participant for a Control Loop
+-----------------------------------------------------------------------------------
+
+The user configures the following properties in the TOSCA template for the kubernetes participant:
+
+.. list-table::
+   :widths: 15 10 50
+   :header-rows: 1
+
+   * - Property
+     - Type
+     - Description
+   * - chartId
+     - ToscaConceptIdentifier
+     - The name and version of the helm chart that needs to be managed by the kubernetes participant
+   * - namespace
+     - String
+     - The namespace in the k8s cluster where the helm chart needs to be installed
+   * - releaseName
+     - String
+     - The helm deployment name that specifies the installed component in the k8s cluster
+   * - repository (optional)
+     - map
+     - A map of *<String, String>* defining the helm repository parameters for the chart
+   * - overrideParams (optional)
+     - map
+     - A map of *<String, String>* defining the helm chart parameters that needs to be overridden
+
+Note: The repository property can be skipped if the helm chart is available in the local chart database or
+in a repository that is already configured on the helm client. The participant does a chart lookup by default.
+
+The *repository* type is described in the following table:
+
+.. list-table::
+   :widths: 15 10 50
+   :header-rows: 1
+
+   * - Field
+     - Type
+     - Description
+   * - repoName
+     - String
+     - The name of the helm repository that needs to be configured on the helm client
+   * - protocol
+     - String
+     - Specifies http/https protocols to connect with repository url
+   * - address
+     - String
+     - Specifies the ip address or the host name
+   * - port (optional)
+     - String
+     - Specifies the port where the repository service is running
+   * - userName (optional)
+     - String
+     - The username to login the helm repository
+   * - password (optional)
+     - String
+     - The password to login the helm repository
+
+
+Kubernetes participant Interactions:
+------------------------------------
+The kubernetes participant interacts with Control Loop Runtime on the northbound via DMaap. It interacts with the helm client on the southbound for performing various helm operations to the k8s cluster.
+
+The communication for the Control loop updates and state change requests are sent from the Control Loop Runtime to the participant via DMaap.
+The participant performs appropriate operations on the k8s cluster via helm client based on the received messages from the Control Loop Runtime.
+
+
+kubernetes participant Workflow:
+--------------------------------
+Once the participant is started, it sends a "REGISTER" event to the DMaap topic which is then consumed by the Control Loop Runtime to register this participant on the runtime database.
+The user can commission the tosca definitions from the Policy Gui to the Control Loop Runtime that further updates the participant with these definitions via DMaap.
+Once the control loop definitions are available in the runtime database, the Control Loop can be instantiated with the default state "UNINITIALISED" from the Policy Gui.
+
+When the state of the Control Loop is changed from "UNINITIALISED" to "PASSIVE" from the Policy Gui, the kubernetes participant receives the control loop state change event from the runtime and
+deploys the helm charts associated with each Control Loop Elements by creating appropriate namespace on the cluster.
+If the repository of the helm chart is not passed via TOSCA, the participant looks for the helm chart in the configured helm repositories of helm client.
+It also performs a chart look up on the local chart database where the helm charts are onboarded via the participant's REST Api.
+
+The participant also monitors the deployed pods for the next 3 minutes until the pods comes to RUNNING state.
+It holds the deployment information of the pods including the current status of the pods after the deployment.
+
+When the state of the Control Loop is changed from "PASSIVE" to "UNINITIALISED" back, the participant also undeploys the helm charts from the cluster that are part of the Control Loop Element.

+Participant Intermediary
+########################
+
+The CLAMP Participant Intermediary is a common library in ONAP, which does common message and
+state handling for participant implementations. It provides a Java API, which participant
+implementations implement to receive and send messages to the CLAMP runtime and to handle
+Control Loop Element state.
+
+Terminology
+-----------
+- Broadcast message: a message for all participants (participantId=null and participantType=null)
+- Message to a participant: a message only for a participant (participantId and participantType properly filled)
+- MessageSender: a class that takes care of sending messages from participant-intermediary
+- GUI: graphical user interface, Postman or a Front-End Application
+
+Inbound messages to participants
+--------------------------------
+- PARTICIPANT_REGISTER_ACK: received as a response from controlloop runtime server as an acknowledgement to ParticipantRegister message sent from a participant
+- PARTICIPANT_DEREGISTER_ACK: received as a response from controlloop runtime server as an acknowledgement to ParticipantDeregister message sent from a participant
+- CONTROL_LOOP_STATE_CHANGE: a message received from controlloop runtime server for a state change of controlloop
+- CONTROL_LOOP_UPDATE: a message received from controlloop runtime server for a controlloop update with controlloop instances
+- PARTICIPANT_UPDATE: a message received from controlloop runtime server for a participant update with tosca definitions of controlloop
+- PARTICIPANT_STATUS_REQ: A status request received from controlloop runtime server to send an immediate ParticipantStatus from all participants
+
+Outbound messages
+-----------------
+- PARTICIPANT_REGISTER: is sent by a participant during startup
+- PARTICIPANT_DEREGISTER: is sent by a participant during shutdown
+- PARTICIPANT_STATUS: is sent by a participant as heartbeat with the status and health of a participant
+- CONTROLLOOP_STATECHANGE_ACK: is an acknowledgement sent by a participant as a response to ControlLoopStateChange
+- CONTROLLOOP_UPDATE_ACK: is an acknowledgement sent by a participant as a response to ControlLoopUpdate
+- PARTICIPANT_UPDATE_ACK: is an acknowledgement sent by a participant as a response to ParticipantUpdate
+
+Design of a PARTICIPANT_REGISTER message
+----------------------------------------
+- A participant starts and send a PARTICIPANT_REGISTER message
+- ParticipantRegisterListener collects the message from DMaap
+- if participant is not present in DB, it saves participant reference with status UNKNOWN to DB
+- if participant is present in DB, it triggers the execution to send a PARTICIPANT_UPDATE message to the participant registered (message of Priming)
+- the message is built by ParticipantUpdatePublisher using Tosca Service Template data (to fill the list of ParticipantDefinition)
+- It triggers the execution to send a PARTICIPANT_REGISTER_ACK message to the participant registered
+- MessageIntercept intercepts that event, if PARTICIPANT_UPDATE message has been sent, it will be add a task to handle PARTICIPANT_REGISTER in SupervisionScanner
+- SupervisionScanner starts the monitoring for participantUpdate
+
+Design of a PARTICIPANT_DEREGISTER message
+------------------------------------------
+- A participant starts and send a PARTICIPANT_DEREGISTER message
+- ParticipantDeregisterListener collects the message from DMaap
+- if participant is not present in DB, do nothing
+- if participant is present in DB, it triggers the execution to send a PARTICIPANT_UPDATE message to the participant registered (message of DePriming)
+- the message is built by ParticipantUpdatePublisher using Tosca Service Template data as null
+- ParticipantHandler removes the tosca definitions stored
+- It triggers the execution to send a PARTICIPANT_DEREGISTER_ACK message to the participant registered
+- Participant is not monitored.
+
+Design of a creation of a Control Loop Type
+-------------------------------------------
+- If there are participants registered with CL-runtime, it triggers the execution to send a broadcast PARTICIPANT_UPDATE message
+- the message is built by ParticipantUpdatePublisher using Tosca Service Template data (to fill the list of ParticipantDefinition)
+- Participant-intermediary will receive a PARTICIPANT_UDPATE message and stores the Tosca Service Template data on ParticipantHandler
+
+Design of a deletion of a Control Loop Type
+-------------------------------------------
+- if there are participants registered, CL-runtime triggers the execution to send a broadcast PARTICIPANT_UPDATE message
+- the message is built by ParticipantUpdatePublisher with an empty list of ParticipantDefinition
+- It deletes the Control Loop Type from DB
+- Participant-intermediary will receive a PARTICIPANT_UDPATE message and deletes the Tosca Service Template data on ParticipantHandler
+
+Design of a creation of a Control Loop
+--------------------------------------
+- CONTROL_LOOP_UPDATE message with instantiation details and UNINITIALISED state is sent to participants
+- Participant-intermediary validates the current state change
+- Participant-intermediary will recieve CONTROL_LOOP_UPDATE message and sends the details of ControlLoopElements to participants
+- Each participant performs its designated job of deployment by interacting with respective frameworks

+-----------------------------------------------------------------------------------
+- CONTROL_LOOP_STATE_CHANGE message with state changed from PASSIVE to RUNNING is sent to participants
+- Participant-intermediary validates the current state change
+- Participant-intermediary will recieve CONTROL_LOOP_STATE_CHANGE message and sends the details of state change to participants
+- Each participant performs its designated job of state change by interacting with respective frameworks

+
+Design of a CONTROLLOOP_UPDATE_ACK message
+------------------------------------------
+- A participant sends CONTROLLOOP_UPDATE_ACK message in response to a CONTROLLOOP_UPDATE message.
+- For each CL-elements moved to the ordered state as indicated by the CONTROLLOOP_UPDATE
+- ControlLoopUpdateAckListener in CL-runtime collects the messages from DMaap
+- It checks the status of all control loop elements and checks if the control loop is primed

+Control Loop Participants
+#########################
+
+A Participant is a component that acts as a bridge between the CLAMP COntrol Loop runtime and components such as
+the Policy Framework, DCAE, or a Kubernetes cluster that are taking part in control loops. It listens
+to DMaaP to receive messages from the CLAMP runtime and performs operations towards components that
+are taking part in control loops. A participant has a Control Loop Element for each control loop in
+which it is taking part.
+
+The implementation of a participant may use a common
+:ref:`Participant Intermediary library <clamp-controlloop-participant-intermediary>`, which carries out common
+message and state handling for Control Loop Elements in participants. The *ParticipantImpelementation* is the
+component specific implementation of a participant, which is specifically developed for each component that
+wishes to take part in control loops.
+
+.. image:: ../../images/participants/participants.png
+
+The figure above shows participants for various components that may take part in control loops.
+
+.. note:: The figure above is for illustration. Not all the participants mentioned above
+          have realizations in ONAP. Some of the participants in the figure above represent
+          a type of participant. For example, a controller participant would be written for
+          a specific controller such as CDS and a participant for an existing system would be
+          written towards that existing system.

+The CLAMP Policy Framework Participant
+######################################
+
+.. contents::
+    :depth: 3
+
+Control Loop Elements in the Policy Framework Participant are configured using TOSCA metadata defined for the Policy Control Loop Element type.
+
+The Policy Framework participant receives messages through participant-intermediary common code, and handles them by invoking REST APIs towards policy-framework.
+
+For example, When a ControlLoopUpdate message is received by policy participant, it contains full ToscaServiceTemplate describing all components participating in a control loop. When the control loop element state changed from UNINITIALIZED to PASSIVE, the Policy-participant triggers the creation of policy-types and policies in Policy-Framework.
+
+When the state changes from PASSIVE to UNINITIALIZED, Policy-Participant deletes the policies, policy-types by invoking REST APIs towards the policy-framework.
+
+Run Policy Framework Participant command line using Maven
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+
+mvn spring-boot:run -Dspring-boot.run.arguments="--server.port=8082"
+
+Run Policy Framework Participant command line using Jar
++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+
+java -jar -Dserver.port=8082 -DtopicServer=localhost target/policy-clamp-participant-impl-policy-6.1.2-SNAPSHOT.jar
+
+Distributing Policies
++++++++++++++++++++++
+
+The Policy Framework participant uses the Policy PAP API to deploy and undeploy policies.
+
+When a Policy Framework Control Loop Element changes from state PASSIVE to state RUNNING, the policy is deployed. When it changes from state RUNNING to state PASSIVE, the policy is undeployed.
+
+The PDP group to which the policy should be deployed is specified in the Control Loop Element metadata, see the Policy Control Loop Element type definition. If the PDP group specified for policy deployment does not exist, an error is reported.
+
+The PAP Policy Status API and Policy Deployment Status API are used to retrieve data to report on the deployment status of policies in Participant Status messages.
+
+The PDP Statistics API is used to get statistics for statistics report from the Policy Framework Participant back to the CLAMP runtime.
+
+Policy Type and Policy References
++++++++++++++++++++++++++++++++++
+
+The Policy Framework uses the policyType and policyId properties defined in the Policy Control Loop Element type references to specify what policy type and policy should be used by a Policy Control Loop Element.
+
+The Policy Type and Policy specified in the policyType and policyId reference must of course be available in the Policy Framework in order for them to be used in Control Loop instances. In some cases, the Policy Type and/or the Policy may be already loaded in the Policy Framework. In other cases, the Policy Framework participant must load the Policy Type and/or policy.
+
+Policy Type References
+**********************
+
+The Policy Participant uses the following steps for Policy Type References:
+
+#. The Policy Participant reads the Policy Type ID from the policyType property specified for the Control Loop Element.
+
+#. It checks if a Policy Type with that Policy Type ID has been specified in the ToscaServiceTemplateFragment field in
+   the ControLoopElement definition in the ControlLoopUpdate message, see :ref:`controlloop-participant-protocol-label`.
+
+  #. If the Policy Type has been specified, the Participant stores the Policy Type in the Policy framework. If the
+     Policy Type is successfully stored, execution proceeds, otherwise an error is reported.
+
+  #. If the Policy Type has not been specified, the Participant checks that the Policy Type is already in the Policy
+     framework. If the Policy Type already exists, execution proceeds, otherwise an error is reported.
+
