• 【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();
