创建并管理组件

操作场景

组件是组成应用的某个业务特性实现，以代码或者软件包为载体，可独立部署在环境下运行。

下面介绍如何调用应用中创建组件API创建组件后，先调用获取部署任务详细信息API查询创建组件任务的状态，再调用根据组件ID修改组件信息API升级组件，然后调用根据组件ID下发组件任务API回滚组件版本，最后再次调用根据组件ID下发组件任务API停止组件实例运行。

API的调用方法请参见如何调用API。

前提条件

已调用获取用户Token获取IAM用户的Token，并将token值设置为环境变量：export Token={token}。
已获取ServiceStage的终端节点，详细信息请参见地区和终端节点，并用于替换以下操作步骤示例中的{servicestage_endpoint}。

操作步骤

调用应用中创建组件API在某个应用下创建组件，请求示例如下：

curl -k -H "Content-Type:application/json;charset=utf8" -H "X-Auth-Token:$token" -X POST "https://{servicestage_endpoint}/v3/{project_id}/cas/applications/{application_id}/components" -d '

    },

        {

            "type": "cce",
            "parameters": {
                "namespace": "default",
                "type": "VirtualMachine"
            }
        }
    ],
    "replica": 2,
    "config_mode": "ui",

    },
    "command": {
        "args": [],
        "command": []
    },
    "custom_metric": {}
}'

返回结果：

{
    "job_id": "JOB870e9ffe-227e-43a9-9c84-20a7ad02e77c",
    "component_id": "f3f6cb89-831d-4579-8bbc-664487889e38"
}

记录返回结果中加粗显示的job_id、component_id的值，用于替换后续示例中的{job_id}、{component_id}。

调用获取部署任务详细信息API查询创建组件任务是否成功，请求示例如下：

curl -k -H "Content-Type:application/json;charset=utf8" -H "X-Auth-Token:$Token" -X GET "https://{servicestage_endpoint}/v3/{project_id}/cas/jobs/{job_id}"

返回结果：

{
    "action": "rollback_current"
}'

返回结果：

{
    "job_id": "JOB66eb56db-062e-4462-ba95-8d3c63d5d462"
}

记录返回结果中加粗显示的job_id的值，用于替换后续示例中的{job_id}。

调用2的接口，用5返回的job_id查询任务状态，等待任务完成。

调用根据组件ID下发组件任务API停止组件实例，请求示例如下：

curl -k -H "Content-Type:application/json;charset=utf8" -H "X-Auth-Token:$token" -X POST "https://{servicestage_endpoint}/v3/{project_id}/cas/applications/{application_id}/components/{component_id}/action" -d ' 
{
    "action": "stop"

返回结果：

{
    "job_id": "JOB2790bf9f-7d6e-473d-827f-1bb94e0cf10d"
}

记录返回结果中加粗显示的job_id的值，用于替换后续示例中的{job_id}。
