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 a root or intermediate key
Logical Cloud creation - Create Istio control planes for the logical clouds.

Different components (microservice) work together with the DCM to make the above possible, the components are;

Main DCM Microservice (contains the service mesh Module(formally Logical Cloud Controller), User Module and Namespace Module, 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)

REST API

1. Create Logical Cloud

Logical Cloud Creation API

URL: /v2/projects/<project-name>/logical-clouds
POST BODY:
{
 "metadata" : {
 	"name": "lc-1",   //unique name for the record
    "description": "logical cloud for walmart finance department",  //description for the logical cloud 
    "userData1":"<user data>",
    "userData2":"<user data>"
   },
 "spec" : {
	"namespace" : "ns-1", // one namespace per logical cloud
 	"user" : {
    "user-name" : "user-1",  //name of user for this cloud  (username and logical cloud name would be used as subject for the user key)
    "type" : "certificate",   //type of authentication credentials used by user (certificate, Token, UNPW)
    "user-permissions" : [
       { "permission-name" : "permission-1",
         "apiGroups" : ["stable.example.com"],
         "resources" : ["secrets", "pods"],
         "verbs" : ["get", "watch", "list", "create"]
       },
       { "permission-name" : "permission-2",
         "apiGroups" : [""],
         "resources" : ["configmaps"],
         "verbs" : ["*"]
       }
    ]
  }
 }
}

Return Status: 201
Return Body:
{
  "name" : "logical-cloud-1",
  "logical-cloud-name" : "logical-cloud-1",
  "namespace" : "ns-1",
  "user-name" : "user-1"
}

Important points to Note

cluster CA and cluster CRT will be gotten when a cluster is registered and this will be used to create the user crt after the user csr and user key are created

Kubeconfig will be put in the mongoDB
