组件管理

更新时间：2020/06/09 GMT+08:00

场景描述

本章节指导用户通过API实现组件管理。API的调用方法请参见如何调用API。

流程介绍

在某个应用下创建组件
创建组件实例
查询创建组件实例任务状态
升级组件实例
获取组件实例快照
回滚组件实例
对组件实例进行其他生命周期的操作，如停止，启动，重启等

前提条件

获取IAM的token，调用Token认证，并将token值设置为环境变量：export Token={token}。
获取ServiceStage的endpoint，参考地区和终端节点，以下示例中以{servicestage_endpoint}代替。

操作步骤

在某个应用下创建组件。调用应用中创建组件接口，请求示例如下。

curl -k -H "Content-Type:application/json" -H "X-Auth-Token:$Token" -X POST "https://{servicestage_endpoint}/v2/{project_id}/cas/applications/{application_id}/components" -d '{
    "name": "component-a", 
    "runtime": "Webapp", 
    "category": "Common", 
    "description": "component_desc", 
    "source": {
        "kind": "artifact", 
        "spec": {
            "storage": "swr", 
            "type": "package", 
            "url": "https://{IP}:20202/xxx/xxx.jar", 
            "auth": "iam"
        }
    }
}'

返回结果：

{
  "id": "string",
  "name": "string",
  "runtime": "Tomcat8",
  "category": "Webapp",
  "sub_category": "Web",
  "description": "string",
  "project_id": "string",
  "application_id": "string",
  "source": {
    "kind": "artifact",
    "spec": {
      "storage": "swr",
      "type": "package",
      "url": "https://{IP}:20202/xxx/xxx.jar",
      "auth": "iam"
    }
  },
  "build": null,
  "pipeline_ids": [],
  "create_time": 0,
  "update_time": 0
}

得到的id，后续示例中以{component_id}代替。

创建组件实例。调用创建组件实例接口。请求示例如下。

curl -k -H "Content-Type:application/json" -H "X-Auth-Token:$Token" -X POST  "https://{servicestage_endpoint}/v2/{project_id}/cas/applications/{application_id}/components/{component_id}/instances" -d '{
    "name": "component-instance-name", 
    "environment_id": "6e763000-9128-4a9d-adea-34c42cc5344d", 
    "flavor_id": "MICRO-5G:0.5C:1G", 
    "replica": 1, 
    "artifacts": {
        "container-name": {
            "storage": "swr", 
            "type": "image", 
            "url": "{IP}:20202/xxxxxxxx/junit-platformstest:1.0", 
            "auth": "iam"
        }
    }, 
    "version": 1, 
    "description": "instance desc", 
    "configuration": {
        "env": [
            {
                "name": "log-level", 
                "value": "warn"
            }
        ]
    }, 
    "refer_resources": [
        {
            "id": "b6862a62-d916-11e9-bdf1-0255ac101fd9", 
            "type": "cce", 
            "parameters": {
                "namespace": "default"
            }
        }, 
        {
            "id": "8c0a45cc-626f-4d65-8257-507ee059aa9a", 
            "type": "elb"
        }
    ]
}'

返回结果：

{
    "instance_id": "89f5baf5-efe4-4f12-9c0d-734d2af5a184", 
    "job_id": "JOB66761060-f209-407c-a093-4df6f531b9dc"
}

得到的job_id，后续示例中以{job_id}代替。得到的instance_id，后续示例中以{instance_id}代替。

查询创建组件实例任务状态。调用获取部署任务详细信息接口，去查询任务状态是否成功。请求示例如下。

curl -k -H "Content-Type:application/json" -H "X-Auth-Token:$Token" -X GET "https://{servicestage_endpoint}/v2/{project_id}/cas/jobs/{job_id}"

返回结果：

        }
    ],

}

升级组件实例。调用修改应用组件实例接口。请求示例如下。然后还是调用步骤3的接口，用返回的job_id查询任务状态，等待升级完成。

curl -k -H "Content-Type:application/json" -H "X-Auth-Token:$Token" -X PUT "https://{servicestage_endpoint}/v2/{project_id}/cas/applications/{application_id}/components/{component_id}/instances/{instance_id}" 
-d '{
    "name": "component-instance-name", 
    "environment_id": "6e763000-9128-4a9d-adea-34c42cc5344d", 
    "flavor_id": "MICRO-5G:0.5C:1G", 
    "replica": 2, 
    "version": 2
}'

返回结果：

{
    "instance_id": "89f5baf5-efe4-4f12-9c0d-734d2af5a184", 
    "job_id": "JOB66761060-f209-407c-a093-4df6f531b9dd"
}

获取组件实例快照。调用获取组件实例快照接口。请求示例如下。该步骤是回退的前置步骤，用于查询可以回退的版本。

curl -k -H "Content-Type:application/json" -H "X-Auth-Token:$Token" -X GET "https://{servicestage_endpoint}/v2/{project_id}/cas/applications/{application_id}/components/{component_id}/instances/{instance_id}/snapshots"

返回结果：

{
    "snapshots": [{
        "create_time": 1571647078435,
        "description": "xxx",
        "instance_id": "89f5baf5-efe4-4f12-9c0d-734d2af5a184",
        "version": "1"
    },
    "count": 1]
}

回滚组件实例。调用对组件实例的操作接口。请求示例如下。然后用返回的job_id调用步骤3等待任务完成。

curl -k -H "Content-Type:application/json" -H "X-Auth-Token:$Token" -X POST "https://{servicestage_endpoint}/v2/{project_id}/cas/applications/{application_id}/components/{component_id}/instances/{instance_id}/action" -d '{
  "action": "rollback",
  "parameters": {
    "version": "1"
  }
}'

返回结果：

{
    "job_id": "JOB66761060-f209-407c-a093-4df6f531b9dc"
}

对组件实例进行其他生命周期的操作，如停止，启动，重启等。调用对组件实例的操作接口。这里以停止组件实例为例子，请求示例如下。然后用返回的job_id调用步骤3等待任务完成。

curl -k -H "Content-Type:application/json" -H "X-Auth-Token:$Token" -X POST "https://{servicestage_endpoint}/v2/{project_id}/cas/applications/{application_id}/components/{component_id}/instances/{instance_id}/action" -d '{
  "action": "stop"
}'

返回结果：

{
    "job_id": "JOB66761060-f209-407c-a093-4df6f531b9dc"
}
