### Giới thiệu

VKS API cho phép người dùng tự động khởi tạo **Cluster** và **Node Group** thay vì thao tác thủ công trên giao diện.\

### Chuẩn bị

| Thành phần                   | Mô tả                            |
| ---------------------------- | -------------------------------- |
| **Token**                    | Bearer token hợp lệ              |
| **VPC / Subnet**             | Đã được tạo sẵn                  |
| **Image / Flavor**           | Kiểm tra danh sách hợp lệ        |
| **SSH Key / Security Group** | Dùng cho truy cập & bảo mật node |

### Tạo Cluster + Node Group qua API

**Endpoint:**

```
POST /v1/clusters
```

**Body ví dụ:**

```json
{
  "name": "cluster-demo-01",
  "version": "v1.29.13-vks.1740045600",

  "enabledLoadBalancerPlugin": true,
  "enabledServiceEndpoint": false,
  "autoUpgradeConfig": null,
  "releaseChannel": "STABLE",
  "fleetConfig": null
}
```

### Tạo Node Group riêng qua API

**Endpoint:**

```
POST /v1/clusters/{clusterId}/node-groups
```

Body tương tự phần `nodeGroups` ở trên.

### Một số API khác

| Mục đích              | API                                |
| --------------------- | ---------------------------------- |
| Lấy danh sách Cluster | `GET /v1/clusters`                 |
| Xóa Cluster           | `DELETE /v1/clusters/{id}`         |
| Lấy kubeconfig        | `GET /v1/clusters/{id}/kubeconfig` |
