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)
);
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
);
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)"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:
- 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,...
- CachingTypes 表示当前磁盘的是只读,还是可读可写
- 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.
- 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

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();"VM instanceView osName: " + vmiv.osName());
System.out.println("VM instanceView osVersion: " + ImageReference vmif = testvm.storageProfile().imageReference();"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")"default")
.withPrivateIPAddressDynamic()
.withNewPublicIPAddress()
