使用ROS CDK批量创建多个资源

产品详情
我的收藏

本文以TypeScript语言为例，为您介绍如何使用ROS CDK批量创建多个资源。

步骤一：初始化工程

执行以下命令，创建工程目录并初始化工程。

mkdir demo
cd demo
ros-cdk init --language=typescript --generate-only=true

步骤二：配置阿里云凭证信息

  1. 执行以下命令，配置阿里云凭证信息。

    ros-cdk config

  2. 根据界面提示输入配置信息。

    ros-cdk config
endpoint(optional, default:https://ros.aliyuncs.com):
defaultRegionId(optional, default:cn-hangzhou):cn-beijing

[1] AK
[2] StsToken
[3] RamRoleArn
[4] EcsRamRole
[0] CANCEL

Authenticate mode [1...4 / 0]: 1
accessKeyId:************************
accessKeySecret:******************************

 ✅ Your cdk configuration has been saved successfully!

步骤三：安装依赖

  1. 修改package.json文件，添加ECS依赖包（ros-cdk-ecs）。

    {
  "name": "demo",
  "version": "0.1.0",
  "bin": {
    "demo": "bin/demo.js"
  },
  "scripts": {
    "build": "tsc",
    "test": "jest"
  },
  "devDependencies": {
    "@types/jest": "^25.2.1",
    "@types/node": "10.17.5",
    "typescript": "^3.9.7",
    "jest": "^25.5.0",
    "ts-jest": "^25.3.1",
    "ts-node": "^8.1.0",
    "babel-jest": "^26.6.3",
    "@babel/core": "^7.12.9",
    "@babel/preset-env": "7.12.7",
    "@babel/preset-typescript": "^7.12.7",
    "@alicloud/ros-cdk-assert": "^1.4.0"
  },
  "dependencies": {
    "@alicloud/ros-cdk-core": "^1.4.0",
    "@alicloud/ros-cdk-ecs": "^1.4.0"
  }
}

  2. 执行以下命令，安装依赖。

    npm install

步骤四：管理资源栈

  1. 修改lib/demo-stack.ts文件，创建安全组。

    通过for循环创建安全组入方向的访问规则（SecurityGroupIngress），实现了批量创建多个资源的诉求，并且代码更为精简。下列提供多语言的示例代码供您参考。

    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 sg = new ecs.SecurityGroup(this, 'ros-cdk-test-sg');

    let PortList= ['22','3389','80'];
    for (let port of PortList) {
       new ecs.SecurityGroupIngress(this, `ros-cdk-test-sg-ingress-${port}`, {
        portRange: `${port}/${port}`,
        nicType: 'intranet',
        sourceCidrIp: '0.0.0.0/0',
        ipProtocol: 'tcp',
        securityGroupId: sg.attrSecurityGroupId
      },true);
    }
  }
}

    Java示例

    package com.myorg;

import com.aliyun.ros.cdk.core.*;

import com.aliyun.ros.cdk.ecs.*;

import java.util.ArrayList;
import java.util.List;

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
        List<String> port_list = new ArrayList<>();
        port_list.add("22");
        port_list.add("3389");
        port_list.add("80");
        SecurityGroup sg = SecurityGroup.Builder.create(this, "sg").build();
        for (String element : port_list) {
            SecurityGroupIngress.Builder.create(this, "ros-cdk-test-sg-ingress-" + element).
                    nicType("intranet").sourceCidrIp("0.0.0.0/0").ipProtocol("tcp").securityGroupId(sg.getAttrSecurityGroupId()).portRange(element + "/" + element).build();
        }

    }
}

    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
        sg = ecs.SecurityGroup(self, "ros-cdk-test-sg")

        prot_list = ["22", "3389", "80"]

        for i in prot_list:
            ecs.SecurityGroupIngress(self, "ros-cdk-test-sg-ingress-" + i,
                                     ecs.SecurityGroupIngressProps(port_range=i + "/" + i, nic_type="intranet",
                                                                   source_cidr_ip="0.0.0.0/0",
                                                                   ip_protocol="tcp",
                                                                   security_group_id=sg.attr_security_group_id))

    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 sg = new SecurityGroup(this, "ros-cdk-test-sg");
            
            object[] portArray = new object[3] {"22", "3389", "80"};

            foreach (var port in  portArray)
            {
                new SecurityGroupIngress(this, "ros-cdk-test-sg-ingress-" + port, new SecurityGroupIngressProps
                {
                    PortRange = port+ "/" + port,
                    NicType = "intranet",
                    SourceCidrIp = "0.0.0.0/0",
                    IpProtocol = "tcp",
                    SecurityGroupId = sg.AttrSecurityGroupId
                });
            }
            
        }
    }
}

  2. 执行以下命令，生成模板文件。

    ros-cdk synth --json

    执行命令后，输出以下内容：

    {
  "Description": "This is the simple ros cdk app example.",
  "Metadata": {
    "ALIYUN::ROS::Interface": {
      "TemplateTags": [
        "Create by ROS CDK"
      ]
    }
  },
  "ROSTemplateFormatVersion": "2015-09-01",
  "Resources": {
    "ros-cdk-test-sg": {
      "Type": "ALIYUN::ECS::SecurityGroup"
    },
    "ros-cdk-test-sg-ingress-22": {
      "Type": "ALIYUN::ECS::SecurityGroupIngress",
      "Properties": {
        "IpProtocol": "tcp",
        "PortRange": "22/22",
        "NicType": "intranet",
        "Priority": 1,
        "SecurityGroupId": {
          "Fn::GetAtt": [
            "ros-cdk-test-sg",
            "SecurityGroupId"
          ]
        },
        "SourceCidrIp": "0.0.0.0/0"
      }
    },
    "ros-cdk-test-sg-ingress-3389": {
      "Type": "ALIYUN::ECS::SecurityGroupIngress",
      "Properties": {
        "IpProtocol": "tcp",
        "PortRange": "3389/3389",
        "NicType": "intranet",
        "Priority": 1,
        "SecurityGroupId": {
          "Fn::GetAtt": [
            "ros-cdk-test-sg",
            "SecurityGroupId"
          ]
        },
        "SourceCidrIp": "0.0.0.0/0"
      }
    },
    "ros-cdk-test-sg-ingress-80": {
      "Type": "ALIYUN::ECS::SecurityGroupIngress",
      "Properties": {
        "IpProtocol": "tcp",
        "PortRange": "80/80",
        "NicType": "intranet",
        "Priority": 1,
        "SecurityGroupId": {
          "Fn::GetAtt": [
            "ros-cdk-test-sg",
            "SecurityGroupId"
          ]
        },
        "SourceCidrIp": "0.0.0.0/0"
      }
    }
  }
}

  3. 执行以下命令，创建资源栈。

    ros-cdk deploy --sync=true

    执行命令后，输出以下内容：

    DemoStack: deploying...
|DemoStack               |2021-12-28T09:17:54 | CREATE_COMPLETE      | ALIYUN::ECS::SecurityGroupIngress | sg-2ze7gbyb0sngx7et**** | ros-cdk-test-sg-ingress-22

 ✅ The deployment(sync deploy stack) has finished!
status: CREATE_COMPLETE
StatusReason: Stack CREATE completed successfully
StackId: a6f1fd14-c985-4dd2-9913-1e7bbeef****

  4. 可选：删除资源栈。

    1. 执行以下命令：

      ros-cdk destroy --sync=true

    2. 根据界面提示，确认删除。

      The following stack(s) will be destroyed(Only deployed stacks will be displayed).

DemoStack

Please confirm.(Y/N)

      执行命令后，输出以下内容：

      DemoStack: destroying...
|DemoStack               | DELETE_COMPLETE      | ALIYUN::ECS::SecurityGroupIngress |  | ros-cdk-test-sg-ingress-22

|DemoStack               | DELETE_COMPLETE      | ALIYUN::ECS::SecurityGroupIngress |  | ros-cdk-test-sg-ingress-80
