基于Conditions在不同操作系统创建ECS-阿里云开发者社区

基于Conditions在不同操作系统创建ECS

1. 编写ROS模板

模板说明

条件（Conditions）由Fn::And、Fn::Or、Fn::Not和Fn::Equals中的一个或多个函数定义，根据您在创建或更新资源栈时，指定的输入参数值进行计算。在每个条件中，都可以引用其他条件、参数值或映射。本文以创建绑定IPv4和IPv6双栈云服务器为例为您介绍。关于模板示例的更多信息，请参见创建绑定IPv4和IPv6双栈云服务器。

在模板中根据Parameters的InstanceImageId参数是否以centos开头做为判断条件，在Conditions对象中使用Fn::Equals、Fn::Select、Fn::Split函数对所选择的InstanceImageId做数据处理与逻辑判断。代码示例如下：

{
  "Parameters": {
    "InstanceImageId": {
      "Type": "String",
      "Default": "centos_7",
      "Description": {
        "zh-cn": "镜像ID, <br>Linux系统请选择：<font color='red'><b>centos_7</b></font> <br>Windows系统请选择：<font color='red'><b>win2008r2；win2012r2；win2016</b></font>",
        "en": "Image ID，<br>Linux System Select：<font color='red'><b>centos_7</b></font> <br>Windows System Select：<font color='red'><b>win2008r2；win2012r2；win2016</b></font>"
      },
      "Label": {
        "zh-cn": "镜像",
        "en": "Image"
      }
    }
  },
  "Conditions": {
    "CreateLinux": {
      "Fn::Equals": [
        "centos",
        {
          "Fn::Select": [
            "0",
            {
              "Fn::Split": [
                "_",
                {
                  "Ref": "InstanceImageId"
                }
              ]
            }
          ]
        }
      ]
    }
  }
}

创建ECS初始化UserData时，使用Fn::If函数判断Conditions对象CreateLinux，实现选择不同操作系统执行不同初始化命令的需求，然后创建IPv4和IPv6双栈云服务器。代码示例如下：

{
  "Fn::If": [
    "CreateLinux",
    {
      "Fn::Replace": [
        {
          "ros-notify": {
            "Fn::GetAtt": [
              "WaitConditionHandle",
              "CurlCli"
            ]
          }
        },
        {
          "Fn::Join": [
            "",
            [
              "#!/bin/sh",
              " \n",
              "cd /opt \n",
              "wget http://ecs-image-utils.oss-cn-hangzhou.aliyuncs.com/ipv6/rhel/ecs-utils-ipv6 \n",
              "chmod +x ./ecs-utils-ipv6 \n",
              "./ecs-utils-ipv6 \n",
              "ros-notify -d \"{\\\"Data\\\" : \\\"SUCCESS\\\", \\\"Status\\\" : \\\"SUCCESS\\\"}\" \n"
            ]
          ]
        }
      ]
    },
    {
      "Fn::Replace": [
        {
          "ros-notify": {
            "Fn::GetAtt": [
              "WaitConditionHandle",
              "PowerShellCurlCli"
            ]
          }
        },
        {
          "Fn::Join": [
            "",
            [
              "[powershell]\r\n",
              "New-Item -Path \"C:\\set_ipv6\" -Force -type directory\r\n",
              "cd C:\\set_ipv6 \r\n",
              "$install_dir=\"C:\\set_ipv6\" \r\n",
              "$install_path = \"$install_dir\\ecs-utils-ipv6.exe\" \r\n",
              "$tool_url = 'http://ecs-image-utils.oss-cn-hangzhou.aliyuncs.com/ipv6/win/64/ecs-utils-ipv6.exe' \r\n",
              "Invoke-WebRequest -uri $tool_url -OutFile $install_path \r\n",
              "Unblock-File $install_path \r\n",
              "Start-Process -FilePath \"$install_path\" -ArgumentList \"--noenterkey\" -NoNewWindow \r\n",
              "ros-notify\r\n"
            ]
          ]
        }
      ]
    }
  ]
}

2. 创建资源栈

以下操作需登录阿里云账号，在资源编排控制台完成以下操作流程。

访问资源编排控制台

1. 进入资源编排控制台。

访问资源栈页面

2. 在资源编排控制台左侧导航栏中单机资源栈。

选择资源创建地域

3. 在页面左上角的地域下拉列表，选择资源栈的所在地域（例如：华北2:北京）。

创建资源栈

4. 在资源栈列表页面，单击创建资源栈，然后在下拉列表中选择使用新资源（标准）。

输入模板

5. 在选择模板页面，选择已有模板：选择输入模板方式，然后将上述示例模板内容复制到模板内容输入框内。然后单击下一步。

模板参数配置

6. 在配置模板参数页面，配置资源栈名称及其余参数，然后单击下一步。

参数配置

参数	说明
专有网络IPv4网段	专有网络的IPv4网段。推荐使用以下网段： 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 更多信息，请参见专有网络和交换机概述。
交换机IPv4网段	专有网络下交换机的IPv4网段。更多信息，请参见专有网络和交换机概述。
交换机可用区	专有网络下的交换机可用区ID。
镜像	ECS实例的镜像ID。可选择Linux（Centos）系列镜像或Windows系列镜像。更多信息，请参见镜像概述。
实例规格	ECS实例规格。请选用有效的实例规格。更多信息，请参见实例规格族。
系统盘空间	ECS实例的系统盘空间。取值范围：40~500。单位：GB。
分配IPv4公网IP	是否为ECS实例分配IPv4公网地址。选中方框：分配公网地址。不选中方框：不分配公网地址。
IPv6公网带宽的计费方式	IPv6公网带宽的计费方式。取值： PayByTraffic：按流量计费。 PayByBandwidth：按带宽计费。
IPv6网关公网带宽	IPv6网关的公网带宽。取值范围：1~5000。单位：Mbps。
IPv6网关的规格	IPv6网关的规格。取值： Small：免费版。 Medium：企业版。 Large：企业增强版。
系统盘类型	ECS实例的系统盘类型。取值： cloud_efficiency：高效云盘。 cloud_ssd：SSD云盘。 cloud_essd：ESSD云盘。 cloud：普通云盘。 ephemeral_ssd：本地SSD盘。更多信息，请参见云盘概述。
实例密码	ECS实例的登录密码。

资源栈信息配置

配置项	说明
资源栈策略	取值：无资源栈策略：不设置资源栈策略。输入资源栈策略：上传文件或在文本框手动输入资源栈策略。关于资源栈策略的更多信息，请参见资源栈策略。
失败时回滚	取值：已启用：创建资源栈失败时，启用回滚策略。已禁用：创建资源栈失败时，禁用回滚策略。
超时设置	如果所有资源的创建或更新没有在该时间内完成，系统将自动回滚到创建或更新之前的状态。取值范围：10~1440。单位：分钟。
删除保护	防止资源栈被意外删除。取值：已启用：启用删除保护。已禁用：禁用删除保护。
RAM角色	您可以创建可信实体为资源编排服务的RAM角色，然后根据ROS模板中资源所需最小权限为RAM角色授权。如果指定RAM角色，ROS将根据RAM角色的权限创建资源栈。关于如何创建RAM角色和为RAM角色授权，请参见创建可信实体为阿里云服务的RAM角色和为RAM角色授权。如果不指定RAM角色，ROS将使用当前账号相关权限创建资源栈。
标签	由一对键值对组成，方便您对资源栈进行分类。您可以单击添加，然后在编辑标签绑定对话框设置标签键和标签值，最后单击确定。
资源组	您可以选择资源栈所在的资源组。如果不指定资源组，资源栈将加入默认资源组。关于如何创建资源组，请参见创建资源组。
