【Azure Developer】使用Java SDK代码创建Azure VM （包含设置NSG，及添加数据磁盘SSD）

在参考Azure官方文档进行VM创建时，发现其中没有包含如何设置NSG的内容，以及如何在创建时就添加数据磁盘的代码（设置磁盘为SSD类型）。本文的内容以“使用 Java 创建和管理 Azure 中的 Windows VM”为基础，在其中添加如何设置NSG（网络安全组 Network Security Group)， 添加数据磁盘并设置类型。

首先，创建虚拟机需要准备的资源有：

• 创建资源组 ResourceGroup

• 创建可用性集 AvailabilitySet

• 创建公共 IP 地址 PublicIPAddress

• 创建虚拟网络 Network

• 创建网络接口 NetworkInterface

• 创建虚拟机 VirtualMachine

以上资源的代码都可以在官网中获取（https://docs.azure.cn/zh-cn/virtual-machines/windows/java#create-resources），本文最后也附带了完整代码，以供参考。接下来就主要介绍NSG部分

创建网络安全组（NSG: NetworkSecurityGroup)

        System.out.println("Creating network security group...");
        NetworkSecurityGroup networksg = azure.networkSecurityGroups().define("myNSG")
                                              .withRegion(Region.CHINA_NORTH)
                                              .withExistingResourceGroup("myResourceGroup")
                                              .create();

注：NSG需要附加在网络接口NetworkInerface中。附加方式如下

NetworkInterface networkInterface = azure.networkInterfaces().define("myNIC")
　　　　　　　　　　.withRegion(Region.CHINA_NORTH)
                 .withExistingResourceGroup("myResourceGroup")
　　　　　　　　　　.withExistingPrimaryNetwork(network).withSubnet("mySubnet")
                 .withPrimaryPrivateIPAddressDynamic()
　　　　　　　　　　.withExistingPrimaryPublicIPAddress(publicIPAddress)
                 .withExistingNetworkSecurityGroup(networksg)
　　　　　　　　　　.create();

添加NSG规则（入站，出站）

        //inbound rule
        networksg.update().defineRule("rule1").allowInbound().fromAddress("125.136.3.25").fromPort(5885).toAnyAddress()
                .toAnyPort().withAnyProtocol().withPriority(300).attach().apply();
        networksg.update().defineRule("rule2").allowInbound().fromAddress("125.136.3.55").fromPort(5899).toAnyAddress()
                .toAnyPort().withAnyProtocol().withPriority(500).attach().apply();

        //outbound rule
        networksg.update().defineRule("rule3").allowOutbound().fromAddress("125.136.3.78").fromPort(6886).toAnyAddress()
                .toAnyPort().withAnyProtocol().withPriority(600).attach().apply();

注：在创建完成networksg后，通过Update()的方式定义Rule。包含入站规则，出站规则，设定源地址，目标地址，源端口，目标端口，协议方式，优先级，操作等。

参数说明；

属性	说明
名称	网络安全组中的唯一名称
优先级	介于 100 和 4096 之间的数字。 规则按优先顺序进行处理。先处理编号较小的规则，因为编号越小，优先级越高。  一旦流量与某个规则匹配，处理即会停止。 因此，不会处理优先级较低（编号较大）的、其属性与高优先级规则相同的所有规则
源或目标	可以是任何值，也可以是单个 IP 地址、无类别域际路由 (CIDR) 块（例如 10.0.0.0/24）、服务标记或应用程序安全组
协议	TCP、UDP、ICMP 或 Any
方向	该规则是应用到入站还是出站流量
端口范围	可以指定单个端口或端口范围。 例如，可以指定 80 或 10000-10005
操作	允许或拒绝

添加数据磁盘

       System.out.println("Creating virtual machine...");
        VirtualMachine virtualMachine = azure.virtualMachines().define("myVM").withRegion(Region.CHINA_NORTH)
                .withExistingResourceGroup("myResourceGroup").withExistingPrimaryNetworkInterface(networkInterface)
                .withLatestWindowsImage("MicrosoftWindowsServer", "WindowsServer", "2012-R2-Datacenter")
                .withAdminUsername("azureuser").withAdminPassword("Azure12345678").withComputerName("myVM")
                .withNewDataDisk(254, 0, CachingTypes.READ_WRITE, StorageAccountTypes.PREMIUM_LRS)
                .withExistingAvailabilitySet(availabilitySet).withSize("Standard_DS1").create();

JDK中WithNewDataDisk接口说明:

            /**
             * Specifies that a managed disk needs to be created implicitly with the given settings.
             *
             * @param sizeInGB the size of the managed disk
             * @param lun the disk LUN
             * @param cachingType a caching type
             * @param storageAccountType a storage account type
             * @return the next stage of the update
             */
            Update withNewDataDisk(int sizeInGB,
                                   int lun,
                                   CachingTypes cachingType,
                                   StorageAccountTypes storageAccountType);

注： 

1.  lun全称为logical unit number，也就是逻辑单元号。在一个VM中是唯一不能重复的数字，如0， 1， 2，...
2.  CachingTypes 表示当前磁盘的是只读，还是可读可写
3.  StorageAccountTypes 则是指定当前磁盘的类型， SSD 或是HDD，虽然SDK中它有四个值，但是中国区只支持Premium_LRS,StandardSSD_LRS,Standard_LRS。分别对应高级SSD，标准SSD，标准HDD.
4.  中国区Azure不支持UltraSSD_LRS类型 。 如在代码中使用它，则会出现如下错误：Exception in thread "main" com.microsoft.azure.CloudException: SKU UltraSSD_LRS is not supported for resource type Disk in this region. Supported SKUs for this region are Premium_LRS,StandardSSD_LRS,Standard_LRS: SKU UltraSSD_LRS is not supported for resource type Disk in this region. Supported SKUs for this region are Premium_LRS,StandardSSD_LRS,Standard_LRS

JDK依赖 pom.xml

    <dependency>
      <groupId>com.microsoft.azure</groupId>
      <artifactId>azure</artifactId>
      <version>1.41.0</version>
    </dependency>

 

附录一：Java SDK获取所有订阅号代码

PagedList<Subscription> allsubs=  Azure.authenticate(credentials).subscriptions().list();

附录二：Java SDK获取当前订阅号下所有虚拟机代码

PagedList<VirtualMachine> allvms = azure.virtualMachines().list();

附录三： Java SDK获取所有的VM Size对应的CPU核数，Memroy大小

PagedList<VirtualMachineSize> vmslist = azure.virtualMachines().sizes().listByRegion(Region.CHINA_EAST);

结果如图

附录四：获取VM的OS Name和Version以及镜像的发布者

        VirtualMachineInstanceView vmiv = testvm.instanceView();

        System.out.println("VM instanceView osName: " + vmiv.osName());
        System.out.println("VM instanceView osVersion: " + vmiv.osVersion());

        ImageReference vmif = testvm.storageProfile().imageReference();

        System.out.println("publisher: " + vmif.publisher());
        System.out.println("offer: " + vmif.offer());
        System.out.println("sku: " + vmif.sku());
        System.out.println("version: " + vmif.version());
        System.out.println("exactVersion: " + vmif.exactVersion());

附录五：为网络接口(NetworkInterface)设置多个IP地址 （Secondary IP Configration）

networkInterface.update()
    .defineSecondaryIPConfiguration("ipconfigtest2")
    .withExistingNetwork(network)
    .withSubnet("default")
    .withPrivateIPAddressDynamic()
    .withNewPublicIPAddress()
.attach().apply();
