根据虚拟机需求获取主机资源的分配信息

POST/zstack/v1/hosts/{uuid}/resource-allocation

Request

cURL

curl --request POST \
  --url '/v1/hosts/{uuid}/resource-allocation' \
  --header 'Content-Type: application/json' \
  --data '{}'

{
  "status": "ok",
  "method": "POST",
  "path": "/v1/hosts/{uuid}/resource-allocation"
}

Headers

Authorization: OAuth the-session-uuid

Body

{
  "params": {
    "strategy": "continuous",
    "scene": "normal",
    "vcpu": 60
  },
  "systemTags": [],
  "userTags": []
}

上述示例中systemTags、userTags字段可以省略。列出是为了表示body中可以包含这两个字段。

Curl示例

curl -H "Content-Type: application/json;charset=UTF-8" \
-H "Authorization: OAuth b86c9016b4f24953a9edefb53ca0678c" \
-X POST //localhost:8080/zstack/v1/hosts/21529457e42c30f0a9b2a137915a0b28/resource-allocation -d '{"params": {"strategy": "continuous", "scene": "normal", "vcpu": 60}}'
