UUI Configuration

Configure CST template UUID and Invariant UUID in slicing.properties file of uui-server microservice

In uui-server microservice, modify the following configuration file, /home/UUI/config/slicing.properties

Add or update the parameters slicing.serviceInvariantUuid and parameter slicing.serviceUuid.

The values of these two parameters come from CST template which can be find on SDC page.

MSB Configuration

Register so-orchestrationTasks and so-serviceInstances interface to MSB.

Interface registration can be done through postman or portal.

Registration information:

{
  "serviceName": "so-orchestrationTasks",
  "version": "v4",
  "url": "/onap/so/infra/orchestrationTasks/v4",
  "protocol": "REST",
  "port": "{{.Values.service.internalPort}}",
  "visualRange": "1",
  "enable_ssl": false
}, 
{
  "serviceName": "so-serviceInstances",
  "version": "v3",
  "url": "/onap/so/infra/e2eServiceInstances/v3",
  "protocol": "REST",
  "port": "{{.Values.service.internalPort}}",
  "visualRange": "1",
  "enable_ssl": false
}

Steps(Portal):

Link: https://{{master server ip}}:30284/iui/microservices/default.html

1.Select ‘Service Discover’ in the left pane

2. Click 'Service Register' button.

3. Input the basic info as the picture shows(also refer to the registration info provided above)

4. Click Add Host button.

Input IP Address and Port then click the 'SAVE' button. （Use cmd ’kubectl get svc -n onap so‘ to confirm IP and port.）

SO Database Update

Insert ORCHESTRATION_URI into service_recipe, SERVICE_MODEL_UUID replaced by CST.ModelId.

INSERT INTO `catalogdb`.`service_recipe`(`ACTION`, `VERSION_STR`, `DESCRIPTION`, `ORCHESTRATION_URI`, `SERVICE_PARAM_XSD`, `RECIPE_TIMEOUT`, `SERVICE_TIMEOUT_INTERIM`, `SERVICE_MODEL_UUID`) VALUES ('createInstance', '1', 'Custom recipe to create communication service-instance if no custom BPMN flow is found', '/mso/async/services/CreateCommunicationService', NULL, 180, NULL, 'c9252b26-f9cd-4e6c-988c-4d6ff39c6dda');

INSERT INTO `catalogdb`.`service_recipe`(`ACTION`, `VERSION_STR`, `DESCRIPTION`, `ORCHESTRATION_URI`, `SERVICE_PARAM_XSD`, `RECIPE_TIMEOUT`, `SERVICE_TIMEOUT_INTERIM`, `SERVICE_MODEL_UUID`) VALUES ('activateInstance', '1.0', 'activate communication service', '/mso/async/services/ActivateCommunicationService', NULL, 180, NULL, 'c9252b26-f9cd-4e6c-988c-4d6ff39c6dda');

Insert ORCHESTRATION_URI into service_recipe, SERVICE_MODEL_UUID is ServiceProfile.ModelId


INSERT INTO `catalogdb`.`service_recipe`(`ACTION`, `VERSION_STR`, `DESCRIPTION`, `ORCHESTRATION_URI`, `SERVICE_PARAM_XSD`, `RECIPE_TIMEOUT`,

A&AI Configuration

If the service distribution to A&AI failed, like the picture shows bellow：

Add 'ServiceProfile' and 'NSTAR' model to A&AI through postman.(ServiceProfile/NSTAR Model Id and Invariant Id can be find on SDC page.)

Postman set as follows :

'ServiceProfile' request· body :

'NSTAR' request· body :

Create Customer and service-subscription

Create customer(5GCustomer) and service-subscription(5G) in AAI.

OOF Configuration

OSDF CHANGES(FOR NST SELECTION)

New NST templates can be added in. There is a json file present in the osdf folder, where the nst templates can be added with the corresponding ModelId and ModelInvariantUUID.

The json file is found in the osdf folder in the corresponding path

apps/nst/optimizers/conf/configIinputs.json

OSDF CHANGES(FOR NSI SELECTION)

1) In OOF charts- oom/kubernetes/oof/resources/config/common-config.yaml, the following changes has to be made before deploying oof.

oof/resources/config/common-config.yml has to be updated to use local policies instead of remote policies. change "global_disabled" from True to False

In oof/resources/config/common-config.yml change the model name - whenever the model name changes, it has to be updated here

EG. when the model name is "Embb_NST". Replace the keys with "slice_selection_policy_dir_embb_nst" & "slice_selection_policy_dir_embb_nst"

This block is an illustration when the model name is- "URLLC_1"

2) AAI preload script should be executed (when we need shared nsi solution to be returned in the response)

This preload AAI script can be run by passing the model invariant id and model version id of NST and NSST in the respective order

( ./pre_v1.sh <model-inv-id of NST> <model-vers-id of NST> <model-inv-id of NSST> <model-vers-id of NSST> )

AAI preload script

3) Local policies (vnf, subscriber & threshold policy) should be copied to the osdf pod

(i) Execute the below script in the test environment by passing nst name, nsst name, model invariant id of NSST & model version id (aka) model uuid of NSST (in the same order as mentioned here)

./policy.sh <NST name> <NSST name> <model-invariant-id of NSST> <model-version-id of NSST>

policy.sh

(ii) after the script gets executed, directory named "test" gets created. Copy the test directory inside the Pod

Example of these three policies can be found in this link https://lf-onap.atlassian.net/wiki/display/DW/Policy+Models+and+Sample+policies+-+NSI+selection
