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" ] ] } ] } ] }
声明创建的资源（Resources）
