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 controller (formally Logical Cloud Controller), User Controller and Namespace Controller, Quota Controller (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

Code Block

language	js
title	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"],

         "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
