Background

The DCM is one of the components of ONAP4K8s. It will run as a microservice exposing Rest APIs, external components will use REST to communicate with the DCM while other microservices will use gRPC. The DCM will perform the following functions;

User creation (currently one user per logical cloud)
Namespace creation (currently one namespace per logical cloud)
Generate intermediate CA key for each edge which is signed by an a root or intermediate key
Logical Cloud creation - Create Istio control planes for the logical clouds.

...

Main DCM Microservice (contains the service mesh Module(formally Logical Cloud Controller), User Controller Module and Namespace Controller)Istio DCM Controller (Create the Istio Control planes for the logical cloudsModule, Quota Module(Limits resources available to each logical cloud))
CA Key Distribution Controller ( Generate intermediate CA key for each edge which is signed by an root or intermediate key)
Quota Controller (Limits resources available to each logical cloud)

API

1. Create Logical Cloud

Code Block

language	js
title	Logical Cloud Creation API

URL: /v2/projects/<project-name>/logical-clouds
POST BODY:
{
 "name": "logical-cloud-1",   //unique name for the new logical cloud
 "description": "logical cloud for walmart finance department",  //description for the logical cloud
 "user" : {
    "name" : "user-1",  //name of user for this cloud
    "type" : "certificate",   //type of authentication credentials used by user (certificate, APIKey, UNPW)
    "certificate" : "/path/to/user1/crt" ,  //Path to user certificate
    "permissions" : {
       "apiGroups" : ["stable.example.com"]
       "resources" : ["secrets", "pods"]
       "verbs" : ["get", "watch", "list", "create"]
     }
  }
}

Return Status: 201
Return Body:
{
  "name" : "logical-cloud-1"
  "user" : "user-1"
  "Message" : "logical cloud and associated user successfully created"
}

Kubeconfig will be generated for the logical cloud

       "verbs" : ["get", "watch", "list", "create"]
     }
  }
}

4. POST (Associate cluster with logical cloud )

DCM Sequence

Client creates logical cloud using logical cloud creation API and the following documents are created in the DCM collection
- The core module parses the Json and creates a new document for the logical cloud in the mongodb DCM collection.
- The core module also creates a cluster document in the DCM collection
- The user module parses the Json and creates a new document for user
- ~~The namespace module parses the Json and creates a new document for namespace~~
Associates logical cloud with clusters (this API is called multiple times)
- Updates the cluster document with the cluster name, loadbalancer ip every time its called
Add quota for logical cloud
- The quota module creates a quota document containing the quota details
Apply API is called
- Service mesh module gets CA bundle from CA controller via gRPC
- Service mesh module gets names of logical cloud and creates a new namespace name using name of logical cloud name
- Service mesh module creates helm template/istioctl manifest (WIP)
- Service mesh module creates service mesh document in the DCM collection and stores the above (CA bundle contents, istio namespace, istioctl manifest) in the document
DCM informs the resource synchronizer to start the logical cloud creation via gRPC and the resource synchronizer starts reading from the DB
The DCM gets status from the resource synchronizer via gRPC
When the logical cloud creation is complete, the resource synchronizer will store the modified kubeconfig file for each cluster in the cluster document of the logical cloud

The details of the DCM Data Model can be found in DCM MongoDB Data Model
