Overview

SDC is a Design platform, as such, we want to create an easy way to add new design capabilities to SDC.

...

The SDC design capabilities are provided by the main design tools, onboarding (VNF design), VF design/import and the service design. In addition to the main

...

designe capabilities, SDC also provides the DCAE-DS blueprint design studio.

At the

...

current state, SDC does not have a standard for adding new designers. because of this, any new integration requires the SDC team to create a specific logic in the SDC code base to support such an integration.

The code changes needed are

...

mostly found in the UI since

...

until now we had to create a designer specific logic to support

...

each integration

Solution concept

We want to create a way where the integration of a new designer is seamless

...

to the SDC

...

and will allow new designers

...

integration without requiring any code addition on the SDC side.

The solution will provide several options for showing the designer as part of SDC. The communication between the SDC and the designers on the UI side will be event based and on the back-end side

...

It will be based on the external API’s that SDC exposes.

Designer

...

Configuration

As part of the integration between SDC and the different plugins, we uphold the concept that SDC can function without any of the different plugins.

The designers enhance the capabilities of SDC they do not prohibit the SDC core functionality.

As a result, we want to create a mechanize that is configured based to decide what designers are shown in the SDC.

Solution

The availability will be based on a REST

...

HEAD call to the plugin UI server to check the availability of the server.

If the server response successfully a relevant flag will be updated to true and the plugin info will be returned in the response if not the flag will be set to false.

...

The SDC UI will execute the call when accessing the plugin page. This way we're making sure that only when the user wants to access the plugin page in the UI the actual online state of this particular plugin will be checked.

High-level overview

The solution will position SDC as a hosting application providing a platform for plugins to enhance the existing capabilities. Each plugin will be treated as a separate service in the eyes of SDC. From the SDC perspective, the plugin can be position anywhere. Because SDC is a multi-tier application we expect the different plugins to uphold the same architecture. There should be a separation between the FE server which is in the DMZ and serves UI pages to the BE server which is in the Protected network, that handles the DB access and the Businesses logic operations. The designer service is loosely integrated with SDC. The two integration points are the plugin UI server location, which is configurable in the FE server configuration and a rest based communication between the plugins backend and SDC backend.

pluginId	String	The id of the plugin
pluginDiscoveryUrl	String	The URL which will be used to check the plugin availability
pluginSourceUrl	String	The URL which will be used to load the plugin pageto load the plugin page
pluginStateUrl	String	The state URL for the UI router
pluginDisplayOptions	Map of objects	An map of object representing the plugin options, the currently supported options are tab and context.
isOnline	Boolean	This value indicates to the SDC UI if the plugin is currently online. If the plugin is down an attempt to open the plugin will result in an error screen.

The configuration allows SDC to control where the plugin UI will be displayed, tab mode or context mode.

Configuration fields

The designer configuration is located under {app base}/config/catalog-fe/plugin-configuration.yaml

Field	Type	Description
connectionTimeout	Integer	This is the number of milliseconds, for the head request to wait for a response from the plugin.
pluginsList	List of objects	A list of plugins’s configurations.	pluginId	String	The name of the plugin.
pluginHostpluginId	String	The host where the designer is locatedname of the plugin.
pluginSourceUrl	String	The plugin URL passed to the UI to retrieve the page.
pluginDiscoveryUrl	String	The plugin URL used for the availability check.
pluginStateUrl	String	The plugin state for UI router.
pluginerDisplayOptions	String	We currently support two work modes for plugins: tab – opens the designer as a tab, for this type we need to set displayName field to define what the tab text and the display roles which define what roles will see the plugin. example: tab: displayName: "Workflow Designer" displayRole: [“TESTER”] context – opens the designer as a context, for this type we need to set displayName field, displayRole and define the displayContext in which the plugin will open, options VF/SERVICE/CP/VL/VFC. example: context: displayName: "monitor" displayRole: [“TESTER”] displayContext: ["VF", "SERVICE"]

UI Integration

SDC need needs to onboard plugins in a way that will be decoupled from the SDC UI implication.

...

Param	Description
userId	The id of the user logged into SDC.
userRole	The role of the connected user, options ADMIN, DESIGNER, TESTER, OPS, GOVERNOR.
displayType	The type of view the plugin is opened in tab/context.
contextType	The type of the context where the plugin is opened: VF/CP/VL/VFC/SERVICE
uuid	Unique id of the context the designer plugin is opened in.
lifecycleState	The state the context /resource or service are currently in: READY_FOR_CERTIFICATION/ CERTIFICATION_IN_PROGRESS/ CERTIFIED/ NOT_CERTIFIED_CHECKIN/ NOT_CERTIFIED_CHECKOUT;
isOwner	A Boolean value describing if the logged user is the owner/lastUpdator of the resource/service.
version	The version of the item displayed.
parentUrl	The URL of the SDC the plugin is opened in. used to subscribe to the event bus in SDC.
eventsClientId	The name with which the plugin needs to register with to the event bus.

...

before you can integrate with SDC you will need to add our pubsub librery in to your aplicationapplication.

SDC will expose a base class in JS as part of the SDC UI project. Any plugin will be able to communicate with SDC after they instantiate this class.
