Installation
============

SON handler microservice can be deployed using cloudify blueprint using bootstrap container of an existing DCAE deployment

Deployment Prerequisites
~~~~~~~~~~~~~~~~~~~~~~~~

- SON-Handler service requires DMAAP and Policy components to be functional.

- SON-hadler service requires  the following dmaap topics to be present in the running DMAAP instance :

        1.PCI-NOTIF-TOPIC-NGHBR-LIST-CHANGE-INFO

        2.unauthenticated.SEC_FAULT_OUTPUT

        3.unauthenticated.SEC_MEASUREMENT_OUTPUT

        4.DCAE_CL_RSP

- Policy model required for SON-handler service should be created and pushed to policy component. Steps for creating and pushing the policy model:
    
        1.Login to PDP container and execute
        
            .. code-block:: bash

                 kubectl exec -ti --namespace onap policy-pdp-0 bash
            
        2.Create policy model
        
            .. code-block:: bash
            
             curl -k -v --silent -X PUT --header 'Content-Type: application/json' --header 'Accept: text/plain' --header 'ClientAuth: cHl0aG9uOnRlc3Q=' --header 'Authorization: Basic dGVzdHBkcDphbHBoYTEyMw==' --header 'Environment: TEST' -d '{
              "policyName": "com.PCIMS_CONFIG_POLICY",
              "configBody": "{ \"PCI_NEIGHBOR_CHANGE_CLUSTER_TIMEOUT_IN_SECS\":60, \"PCI_MODCONFIG_POLICY_NAME\":\"ControlLoop-vPCI-fb41f388-a5f2-11e8-98d0-529269fb1459\", \"PCI_OPTMIZATION_ALGO_CATEGORY_IN_OOF\":\"OOF-PCI-OPTIMIZATION\", \"PCI_SDNR_TARGET_NAME\":\"SDNR\" }",
              "policyType": "Config", "attributes" : { "matching" : { "key1" : "value1" } },
              "policyConfigType": "Base",
              "onapName": "DCAE",
              "configName": "PCIMS_CONFIG_POLICY",
              "configBodyType": "JSON" }' 'https://pdp:8081/pdp/api/createPolicy'

        3.Push policy model
        
            .. code-block:: bash
            
               curl -k -v --silent -X PUT --header 'Content-Type: application/json' --header 'Accept: text/plain' --header 'ClientAuth: cHl0aG9uOnRlc3Q=' --header 'Authorization: Basic dGVzdHBkcDphbHBoYTEyMw==' --header 'Environment: TEST' -d '{
              "policyName": "com.PCIMS_CONFIG_POLICY",
              "policyType": "Base"}' 'https://pdp:8081/pdp/api/pushPolicy'

        4.Verify config policy is present

            .. code-block:: bash
        
                 curl -k -v --silent -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'ClientAuth: cHl0aG9uOnRlc3Q=' --header 'Authorization: Basic dGVzdHBkcDphbHBoYTEyMw==' --header 'Environment: TEST' -d '{ "configName": "PCIMS_CONFIG_POLICY",    "policyName": "com.Config_PCIMS_CONFIG_POLICY1*",    "requestID":"e65cc45a-9efb-11e8-98d0-529269ffa459"  }' 'https://pdp:8081/pdp/api/getConfig' 

Deployment steps
~~~~~~~~~~~~~~~~
1.Using DCAE Dashboard
 - Login to DCAE Dashboard
 - Go to Inventory --> Blueprints 
 - Upload son-handler blueprint which can be found under blueprints repo (https://gerrit.onap.org/r/dcaegen2/platform/blueprints)
 - Click on Deploy Action for son-handler blueprint
 - Deployment logs can be viewed under Deployments section 

2.Using cloudify commands 

- Login to the bootstrap container
        kubectl exec -ti --namespace onap <bootstrap pod name> bash
- The blueprint can be found under dcaegen2 blueprint repo and is part of bootstrap container. (https://gerrit.onap.org/r/dcaegen2/platform/blueprints)
- Deploy the microservice into the cloudify using the following command
        cfy install -d sonhms -b sonhms <blueprint file path>
- Deployment status of the microservice can be found from kubernetes pods status (MS will be deployed as a k8s pod in the kubernetes environment under the same namespace as the DCAE environment).
        kubectl get pods --namespace onap
- To uninstall the microservice
        cfy uninstall sonhms
- To delete the blueprint from the cloudify instance
        cfy blueprints delete sonhms
