Problem

• How to use the Qbert API to create new K8S cluster?

• How to create a k8s cluster using Qbert API and Private Docker Registry

Environment

• Platform9 Managed Kubernetes - all version

Procedure

Warning

Before creating cluster you need to setup a docker repository with all required docker images

• Generate a Keystone authentication token with project scope by following Keystone Identity API.

• Use below API to create a new cluster with private docker repository

curl -i -X POST \
   -H "Content-Type: application/json" \
   -H "X-Auth-Token: $TOKEN" \
   -d \
'{
    "nodePoolUuid" : "<node_pool_uuid>",
    "allowWorkloadsOnMaster" : true,
	  "name": "<cluster_name>",
	  "containersCidr": "<container_cidr>",
	  "networkPlugin": "calico",
	  "servicesCidr": "<service_cidr>",
	  "kubeRoleVersion": "<kube_role_version>",
	  "containerRuntime": "<container_runtime>",
	  "dockerPrivateRegistry": "<private_docker_registry_url>",
	  "k8sPrivateRegistry": "<private_docker_registry_url>",
	  "gcrPrivateRegistry": "<private_docker_registry_url>",
	  "quayPrivateRegistry": "<private_docker_registry_url>",
    "privileged" : true
}' \
 'https://<FQDN>/qbert/v4/<project_uuid>/clusters'

• Once the cluster is created attach a node as master using below API call

Bash

curl -i -X POST \
   -H "Content-Type: application/json" \
   -H "X-Auth-Token: $TOKEN" \
   -d \
'[
  {
    "uuid": "<node_uuid>",
    "isMaster": true
  }
]' \
 'https://<FQDN>/qbert/v4/<project_uuid>/clusters/<new_cluster_uuid>/attach'

• Once master node is attached to the cluster and becomes ready, you can attach worker node using same API call to add the node changing 'isMaster' parameter to false
