ZStack - 创建物理机

/ 前言 /

在ZStack的API中, 大多数的API返回的是一个任务结果查询地址, 此时我们就需要根据这个地址轮训去查询任务状态及结果

{ 
	"location": "http://localhost:8080/v1/api-jobs/967a26b7431c49c0b1d50d709ef1aef3" 
}

我们知道ZStack中有管理节点和计算节点的概念, 创建物理机其实就是将已有的计算节点添加到管理节点中, 方便后续操作

创建物理机

API名称

添加KVM主机(AddKVMHost)
请求方式

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
}}

ZStack中, 大多数的API在调用后返回的是

user_name = 'admin'
user_password='password'
host = 'http://localhost:8080/'

def create_host(cluster_uuid, session_uuid):
	# 需要注意的是managementIp这个参数必须是当前已有结算节点的ip地址, 且管理节点可以ping通该ip
