您可以解析ROS CDK代码，生成如下ROS模板：
{
"Description": "This is the simple ros cdk app example.",
"Metadata": {
"ALIYUN::ROS::Interface": {
"TemplateTags": [
"Create by ROS CDK"
]
}
},
"ROSTemplateFormatVersion": "2015-09-01",
"Parameters": {
"VpcCidrBlock": {
"Type": "String",
"Description": "The CIDR block of the VPC.",
"AssociationProperty": "ALIYUN::VPC::VPC::CidrBlock"
},
"VSwitchCidrBlock": {
"Type": "String",
"Description": "The CIDR block of the VSwitch.",
"AssociationProperty": "ALIYUN::VPC::VSwitch::CidrBlock"
},
"ZoneId": {
"Type": "String",
"Description": "Availability Zone ID.",
"AssociationProperty": "ZoneId"
}
},
"Resources": {
"vpc": {
"Type": "ALIYUN::ECS::VPC",
"Properties": {
"CidrBlock": {
"Ref": "VpcCidrBlock"
},
"EnableIpv6": false,
"VpcName": "demo001"
}
},
"vswitch": {
"Type": "ALIYUN::ECS::VSwitch",
"Properties": {
"CidrBlock": {
"Ref": "VSwitchCidrBlock"
},
"VpcId": {
"Fn::GetAtt": [
"vpc",
"VpcId"
]
},
"ZoneId": {
"Ref": "ZoneId"
}
}
}
}
}资源
ROS支持为模板中的资源设置DependsOn、Count和Condition属性，具体如下：
DependsOn
设置DependsOn属性，可以指定特定资源紧跟着另一个资源后创建。为某个资源添加DependsOn属性后，该资源仅在DependsOn属性中指定的资源之后创建。您可以通过以下代码在ROS CDK中设置DependsOn属性。
TypeScript示例
import * as ros from '@alicloud/ros-cdk-core'; import * as ecs from '@alicloud/ros-cdk-ecs'; export class DemoStack extends ros.Stack { constructor(scope: ros.Construct, id: string, props?: ros.StackProps) { super(scope, id, props); new ros.RosInfo(this, ros.RosInfo.description, "This is the simple ros cdk app example."); // The code that defines your stack goes here const vpc = new ecs.Vpc(this, 'ROS-VPC', { vpcName: 'VPC_Name', cidrBlock: '10.0.0.0/8', enableIpv6: false, description: 'This is the description of VPC', }); const vswitch = new ecs.VSwitch(this, 'ROS-VSwitch', { vpcId: vpc.getAtt('VpcId'), zoneId: 'cn-beijing-h', vSwitchName: 'VSwitch_Name', cidrBlock: '10.0.0.0/20' }); vswitch.addDependency(vpc); } }Java示例
package com.myorg; import com.aliyun.ros.cdk.core.*; import com.aliyun.ros.cdk.ecs.*; public class DemoStack extends Stack { public DemoStack(final Construct scope, final String id) { this(scope, id, null); } public DemoStack(final Construct scope, final String id, final StackProps props) { super(scope, id, props); // The code that defines your stack goes here Vpc vpc = Vpc.Builder.create(this, "ROS-VPC").vpcName("VPC_Name"). description("This is the description of VPC").cidrBlock("10.0.0.0/8").enableIpv6(false).build(); VSwitch vswitch = VSwitch.Builder.create(this, "ROS-VSwitch").vpcId(vpc.getAttrVpcId()). cidrBlock("10.0.0.0/20").zoneId("cn-beijing-h").vSwitchName("VSwitch_Name").build(); vswitch.addDependency(vpc); } }Python示例
import ros_cdk_core as core import ros_cdk_ecs as ecs class DemoStack(core.Stack): def __init__(self, scope: core.Construct, construct_id: str, **kwargs) -> None: super().__init__(scope, construct_id, **kwargs) # The code that defines your stack goes here vpc = ecs.Vpc(self, "ROS-VPC", ecs.VPCProps( cidr_block="10.0.0.0/8", vpc_name="VPC_Name", description="This is the description of VPC", enable_ipv6=False )) vswitch = ecs.VSwitch(self, "ROS-VSwitch", ecs.VSwitchProps( cidr_block="10.0.0.0/20", zone_id="cn-beijing-h", vpc_id=vpc.attr_vpc_id, v_switch_name="VSwitch_Name" )) vswitch.add_dependency(vpc)C#示例
using AlibabaCloud.SDK.ROS.CDK.Core; using AlibabaCloud.SDK.ROS.CDK.Ecs; namespace Demo { public class DemoStack : Stack { public DemoStack(Construct scope, string id, IStackProps props = null) : base(scope, id, props) { // The code that defines your stack goes here var Vpc = new Vpc(this, "ROS-VPC", new VPCProps { CidrBlock = "10.0.0.0/8", VpcName = "VPC_Name", Description = "This is the description of VPC", EnableIpv6 = false }); var VSwitch = new VSwitch(this, "ROS-VSwitch", new VSwitchProps { CidrBlock = "10.0.0.0/20", ZoneId = "cn-beijing-h", VpcId = Vpc.AttrVpcId, VSwitchName = "VSwitch_Name" }); VSwitch.AddDependency(Vpc); } } }您可以解析ROS CDK代码，生成如下ROS模板：
{ "Description": "This is the simple ros cdk app example.", "Metadata": { "ALIYUN::ROS::Interface": { "TemplateTags": [ "Create by ROS CDK" ] } }, "ROSTemplateFormatVersion": "2015-09-01", "Resources": { "ROS-VPC": { "Type": "ALIYUN::ECS::VPC", "Properties": { "CidrBlock": "10.0.0.0/8", "Description": "This is the description of VPC", "EnableIpv6": false, "VpcName": "VPC_Name" } }, "ROS-VSwitch": { "Type": "ALIYUN::ECS::VSwitch", "Properties": { "CidrBlock": "10.0.0.0/20", "VpcId": { "Fn::GetAtt": [ "ROS-VPC", "VpcId" ] }, "ZoneId": "cn-beijing-h", "VSwitchName": "VSwitch_Name" }, "DependsOn": [ "ROS-VPC" ] } } }Count
为资源指定Count属性后，ROS会对模板进行预处理，把该资源展开成多个资源。 操作资源栈时使用处理后的模板。您可以通过以下代码在ROS CDK中设置Count属性。
TypeScript示例
import * as ros from '@alicloud/ros-cdk-core'; import * as ecs from '@alicloud/ros-cdk-ecs'; export class DemoStack extends ros.Stack { constructor(scope: ros.Construct, id: string, props?: ros.StackProps) { super(scope, id, props); new ros.RosInfo(this, ros.RosInfo.description, "This is the simple ros cdk app example."); // The code that defines your stack goes here const vpc = new ecs.Vpc(this, 'ROS-VPC', { cidrBlock: '10.0.0.0/8', enableIpv6: false, }); vpc.addCount(2) const vsw =new ecs.VSwitch(this, `vsw-from-ros-cdk`, { vpcId: ros.Fn.select(ros.RosPseudo.index, vpc.attrVpcId), zoneId: ros.Fn.select(ros.RosPseudo.index, ros.Fn.getAzs(ros.RosPseudo.region)), cidrBlock: '10.0.0.0/16', }); vsw.addCount(2) } }Java示例
package com.myorg; import com.aliyun.ros.cdk.core.*; import com.aliyun.ros.cdk.ecs.*; public class DemoStack extends Stack { public DemoStack(final Construct scope, final String id) { this(scope, id, null); } public DemoStack(final Construct scope, final String id, final StackProps props) { super(scope, id, props); // The code that defines your stack goes here Vpc vpc = Vpc.Builder.create(this, "ROS-VPC").cidrBlock("10.0.0.0/8").enableIpv6(false).build(); vpc.addCount(2); VSwitch vswitch = VSwitch.Builder.create(this, "vsw-from-ros-cdk"). vpcId(Fn.select(RosPseudo.getIndex(), vpc.getAttrVpcId())). cidrBlock("10.0.0.0/16"). zoneId(Fn.select(RosPseudo.getIndex(), Fn.getAzs(RosPseudo.getRegion()))).build(); vswitch.addCount(2); } }Python示例
import ros_cdk_core as core import ros_cdk_ecs as ecs class DemoStack(core.Stack): def __init__(self, scope: core.Construct, construct_id: str, **kwargs) -> None: super().__init__(scope, construct_id, **kwargs) # The code that defines your stack goes here vpc = ecs.Vpc(self, "ROS-VPC", ecs.VPCProps( cidr_block="10.0.0.0/8", enable_ipv6=False )) vpc.add_count(2) vswitch = ecs.VSwitch(self, "vsw-from-ros-cdk", ecs.VSwitchProps( cidr_block="10.0.0.0/16", zone_id=core.Fn.select(core.RosPseudo.index, core.Fn.get_azs(core.RosPseudo.region)), vpc_id=core.Fn.select(core.RosPseudo.index, vpc.attr_vpc_id) )) vswitch.add_count(2)C#示例
using AlibabaCloud.SDK.ROS.CDK.Core; using AlibabaCloud.SDK.ROS.CDK.Ecs; namespace Demo { public class DemoStack : Stack { public DemoStack(Construct scope, string id, IStackProps props = null) : base(scope, id, props) { // The code that defines your stack goes here var Vpc = new Vpc(this, "ROS-VPC", new VPCProps { CidrBlock = "10.0.0.0/8", EnableIpv6 = false }); Vpc.AddCount(2); var VSwitch = new VSwitch(this, "vsw-from-ros-cdk", new VSwitchProps { CidrBlock = "10.0.0.0/16", ZoneId = Fn.Select(RosPseudo.Index, Fn.GetAzs(RosPseudo.Region)), VpcId = Fn.Select(RosPseudo.Index, Vpc.AttrVpcId) }); VSwitch.AddCount(2); } } }您可以解析ROS CDK代码，生成如下ROS模板：

使用Condition属性可以指定是否需要创建资源。只有Condition所指定的条件值为True时，才会创建此资源。您可以通过以下代码在ROS CDK中设置Condition属性。
TypeScript示例
import * as ros from '@alicloud/ros-cdk-core'; import * as ecs from '@alicloud/ros-cdk-ecs'; export class DemoStack extends ros.Stack { constructor(scope: ros.Construct, id: string, props?: ros.StackProps) { super(scope, id, props); new ros.RosInfo(this, ros.RosInfo.description, "This is the simple ros cdk app example."); // The code that defines your stack goes here const createVPC = new ros.RosParameter(this, 'CreateVPC', { type: ros.RosParameterType.BOOLEAN, defaultValue: true, }); const isCreateVPC = new ros.RosCondition(this, 'IsCreateVPC', { expression: ros.Fn.conditionEquals(true, createVPC.valueAsBoolean), }); const vpc = new ecs.Vpc(this, 'ROS-VPC', { vpcName: 'VPC_Name', cidrBlock: '10.0.0.0/8', enableIpv6: false, description: 'This is the description of VPC', }); vpc.addCondition(isCreateVPC) } }Java示例
