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

Environment

Platform9 Managed Kubernetes - all version

Procedure

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

Bash
    
xxxxxxxxxx
 
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'
Copy

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

Bash
    
xxxxxxxxxx
 
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'
Copy

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
