/ 前言 /
在ZStack的API中, 大多數的API返回的是一個任務結果查詢地址, 此時我們就需要根據這個地址輪訓去查詢任務狀態及結果
{
"location": "http://localhost:8080/v1/api-jobs/967a26b7431c49c0b1d50d709ef1aef3"
}
我們知道ZStack中有管理節點和計算節點的概念, 創建物理機其實就是將已有的計算節點添加到管理節點中, 方便後續操作

創建物理機
-
API名稱
添加KVM主機(AddKVMHost)
-
請求方式
POST
zstack/v1/hosts/kvm -
curl示例
curl -H "Content-Type: application/json" \ -H "Authorization: OAuth b86c9016b4f24953a9edefb53ca0678c" \ -X POST -d '{"params":{"username":"userName","password":"password","sshPort":"22","name ":"newHost","managementIp":"127.0.0.1","clusterUuid":"9adf394ca46432afb1218d220bf2925e "}}' \ http://localhost:8080/zstack/v1/hosts/kvm -
返回示例
{"inventory": { "zoneUuid": "d4160c59319c4642832e666514364a79", "name": "example", "uuid": "479e88bab7a647e3b066a724c8bb3b82", "clusterUuid": "42ade59801804602b9986b42fd103d1c", "description": "example", "managementIp": "192.168.0.1", "hypervisorType": "KVM", "state": "Enabled", "status": "Connected", "totalCpuCapacity": 4.0, "availableCpuCapacity": 2.0, "totalMemoryCapacity": 4.0, "availableMemoryCapacity": 4.0 }}
