ZStack RESTful API cookbook

前言

本书将指导用户如何通过REST API来生成基于ZStack企业版的私有云环境。本书面向的对象是有基于ZStack RESTful API做二次开发需求的读者，或希望将ZStack整合进公司已有业务系统需求的读者。
在阅读本书之前，读者需阅读《ZStack 企业版开发手册》，了解ZStack目前提供的RESTful API使用方式。
本书分为两个章节，第一章节为基本场景，主要描述如何对ZStack中的基本资源做操作。第二章节为特定的私有云场景，主要描述一些现实环境中的私有云部署方案，并描述如何基于ZStack提供的基本资源，通过RESTful API完成私有云场景的创建。

第一章基本场景操作

场景1：登录ZStack（Login）

REST由于是无状态的传输，所以每一次请求都得带上身份认证信息。读者如果想通过rest API 来创建一个私有云环境，首先需要通过ZStack的API: LogInByAccount 获得一个令牌，这个令牌作为之后每一步操作的身份认证信息。

//声明sessionId；每个action均需要sessionId
String sessionId;
//设置登录zstack的地址
ZSConfig.Builder zBuilder = new ZSConfig.Builder();
zBuilder.setContextPath("zstack");
zBuilder.setHostname("172.20.12.9");
ZSClient.configure(zBuilder.build());
//登录zstack；获取session；需要对密码进行SHA-512算法加密
LogInByAccountAction logInByAccountAction = new LogInByAccountAction();
logInByAccountAction.accountName = "admin";
logInByAccountAction.password = SHA("password", "SHA-512");
LogInByAccountAction.Result logInByAccountActionRes = logInByAccountAction.call();
sessionId = logInByAccountActionRes.value.getInventory().getUuid();

场景2 创建区域（Zone）

拿到login的令牌之后，第一步是创建一个区域。一个区域是由类似主存储，集群，L2网络的资源组成的逻辑组; 它定义一个可见的边界，在相同区域中的资源互相可见并且可以形成某种关系，但在不同区域中的资源是不行的. 例如, 区域A中的一个主存储可以挂载到区域A中的一个集群，但不能挂载到区域B的集群上。区域的子资源，包括集群，L2网络和主存储等。

CreateZoneAction createZoneAction = new CreateZoneAction();
createZoneAction.name = "zone1";
createZoneAction.description = "this is a zone";
createZoneAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
ZoneInventory zone = createZoneAction.call().value.inventory;

场景3 创建集群（Cluster）

区域创建完成后，需要创建集群。一个集群是类似主机（Host）组成的逻辑组。在同一个集群中的主机必须安装相同的操作系统，拥有相同的二层网络连接，可以访问相同的主存储。在实际的数据中心，一个集群通常对应一个机架（rack）。

CreateClusterAction createClusterAction = new CreateClusterAction();
createClusterAction.zoneUuid = "dad0910508e8498da2f247174ab714bc";
createClusterAction.name = "cluster1";
createClusterAction.description = "this is a cluster";
createClusterAction.hypervisorType = "KVM";
createClusterAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
ClusterInventory cluster = createClusterAction.call().value.inventory;

场景4 添加物理机（Host）

集群创建完后，再添加物理机。物理机是一个安装有操作系统的物理服务器。

AddKVMHostAction addKVMHostAction = new AddKVMHostAction();
addKVMHostAction.name = "host1";
addKVMHostAction.username = "root";
addKVMHostAction.password = "password";
addKVMHostAction.clusterUuid = "db2e569c4e2c41448fb6f9309d2bf52f";
addKVMHostAction.managementIp = "172.20.12.9";
addKVMHostAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
HostInventory host = addKVMHostAction.call().value.inventory;

场景5 添加主存储（Primary Storage）

添加完物理机之后，再添加主存储。主存储是数据中心里为云主机提供根云盘和数据云盘的存储系统. ZStack的主存储分多种类型，包括LocalStorage，NFS，Ceph，FusionStor，Shared Mount Point

//这里添加本地主存储
AddLocalPrimaryStorageAction addLocalPrimaryStorageAction = new AddLocalPrimaryStorageAction();
addLocalPrimaryStorageAction.url = "/zstack_ps";
addLocalPrimaryStorageAction.name = "ps1";
addLocalPrimaryStorageAction.zoneUuid = "dad0910508e8498da2f247174ab714bc";
addLocalPrimaryStorageAction.sessionId = sessionId;
PrimaryStorageInventory primaryStorage = addLocalPrimaryStorageAction.call().value.inventory;
//将本地主存储挂载到集群
AttachPrimaryStorageToClusterAction attachPrimaryStorageToClusterAction = new AttachPrimaryStorageToClusterAction();
attachPrimaryStorageToClusterAction.clusterUuid = "db2e569c4e2c41448fb6f9309d2bf52f";
attachPrimaryStorageToClusterAction.primaryStorageUuid = "0e6f4c9d89bd4cc2b0cb420568ee46ec";
attachPrimaryStorageToClusterAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
attachPrimaryStorageToClusterAction.call();

场景6 添加备份存储（Backup Storage）

添加完主存储之后，再添加备份存储。备份存储又叫镜像服务器。备份存储是保存用于创建云盘的镜像的存储系统。Mevoco的备份存储分多种类型，包括ImageStore，Ceph，FusionStor

//这里添加本地备份存储
AddImageStoreBackupStorageAction addImageStoreBackupStorageAction = new AddImageStoreBackupStorageAction();
addImageStoreBackupStorageAction.hostname = "172.20.12.9";
addImageStoreBackupStorageAction.username = "root";
addImageStoreBackupStorageAction.password = "password";
addImageStoreBackupStorageAction.url = "/zstack_bs";
addImageStoreBackupStorageAction.name = "bs1";
addImageStoreBackupStorageAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
ImageStoreBackupStorageInventory imageStoreBackupStoage = addImageStoreBackupStorageAction.call().value.inventory;
//将镜像存储挂载到集群
AttachBackupStorageToZoneAction attachBackupStorageToZoneAction = new AttachBackupStorageToZoneAction();
attachBackupStorageToZoneAction.zoneUuid = "dad0910508e8498da2f247174ab714bc";
attachBackupStorageToZoneAction.backupStorageUuid = "15a01470b6fb4468b64b62ae58eb22c0";
attachBackupStorageToZoneAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
attachBackupStorageToZoneAction.call();

场景7 添加二层网络（L2 Network）

存储和物理机全部添加完成后，我们具备了基本云主机启动条件，下面我们为云主机创建网络环境。首先，创建二层网络。L2网络在数据中心中代表了一个二层广播域，在ZStack中, L2网络负责为L3网络提供二层隔离。

//创建无服务L2NoVlan网络
CreateL2NoVlanNetworkAction createL2NoVlanNetworkAction = new CreateL2NoVlanNetworkAction();
createL2NoVlanNetworkAction.name = "public-management-l2";
createL2NoVlanNetworkAction.description = "this is a no-serivce network";
createL2NoVlanNetworkAction.zoneUuid = "dad0910508e8498da2f247174ab714bc";
createL2NoVlanNetworkAction.physicalInterface = "eth0";
createL2NoVlanNetworkAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
L2NetworkInventory l2NoVlanNetwork = createL2NoVlanNetworkAction.call().value.inventory;
//挂载无服务L2NoVlan网络到集群
AttachL2NetworkToClusterAction attachL2NoVlanNetworkToClusterAction = new AttachL2NetworkToClusterAction();
attachL2NoVlanNetworkToClusterAction.l2NetworkUuid = d45c8fea42324c939b71931eabb7f932;
attachL2NoVlanNetworkToClusterAction.clusterUuid = "db2e569c4e2c41448fb6f9309d2bf52f";
attachL2NoVlanNetworkToClusterAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
attachL2NoVlanNetworkToClusterAction.call();

场景8 添加三层网络（L3 Network）

二层网络创建完成后，需要创建三层网络。三层网络是由子网（subnet）以及一系列网络服务（network services）组成。网络服务提供模块（network service providers）提供的网络服务, 通常是OSI三层到七层协议的软件实现。

//基于L2NoVlan网络创建L3网络,作为公有网络
CreateL3NetworkAction createL3PublicNetworkAction = new CreateL3NetworkAction();
createL3PublicNetworkAction.name = "public-management-l3";
createL3PublicNetworkAction.type = "L3BasicNetwork";
createL3PublicNetworkAction.l2NetworkUuid = "68a05a0154d4472bb7a059b54a53f166";
createL3PublicNetworkAction.system = false;
createL3PublicNetworkAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
L3NetworkInventory l3PublicNetwork = createL3PublicNetworkAction.call().value.inventory;
//挂载IP地址段到公有网络；
AddIpRangeAction addIpRangeAction = new AddIpRangeAction();
addIpRangeAction.l3NetworkUuid = "917fe2f51ab7423ca6e74648c5ae8931";
addIpRangeAction.name = "iprange1";
addIpRangeAction.startIp = "10.101.50.2";
addIpRangeAction.endIp = "10.101.50.254";
addIpRangeAction.netmask = "255.0.0.0";
addIpRangeAction.gateway = "10.0.0.1";
addIpRangeAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
addIpRangeAction.call();
//为共有网络private-l3添加DNS服务
AddDnsToL3NetworkAction addDnsToL3NetworkAction = new AddDnsToL3NetworkAction();
addDnsToL3NetworkAction.l3NetworkUuid = "917fe2f51ab7423ca6e74648c5ae8931";
addDnsToL3NetworkAction.dns = "8.8.8.8";
addDnsToL3NetworkAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
addDnsToL3NetworkAction.call();
//获取网络服务的Uuid
QueryNetworkServiceProviderAction queryNetworkServiceProviderAction = new QueryNetworkServiceProviderAction();
queryNetworkServiceProviderAction.conditions = Collections.singletonList("type=Flat");
queryNetworkServiceProviderAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
NetworkServiceProviderInventory networkServiceProvider = queryNetworkServiceProviderAction.call().value.inventories.get(0);
Map<String, List<String>> networkServices = new HashMap<String, List<String>>();
networkServices.put(networkServiceProvider.uuid, asList("DHCP", "Eip", "Userdata"));
//为公有网络添加网络服务
AttachNetworkServiceToL3NetworkAction attachNetworkServiceToL3NetworkAction = new AttachNetworkServiceToL3NetworkAction();
attachNetworkServiceToL3NetworkAction.l3NetworkUuid = ""68a05a0154d4472bb7a059b54a53f166"";
attachNetworkServiceToL3NetworkAction.networkServices = networkServices;
attachNetworkServiceToL3NetworkAction.sessionId = sessionId;
attachNetworkServiceToL3NetworkAction.call();

场景9 创建计算规格（Instance Offering）

三层网络创建完后，云主机的基本环境已经准备就绪，现在，需要设置云主机的计算规格。计算规格定义了云主机的内存，CPU以及云主机的磁盘IO和网络带宽IO。

//创建计算规格
CreateInstanceOfferingAction createInstanceOfferingAction = new CreateInstanceOfferingAction();
createInstanceOfferingAction.name = "instanceoffering1";
createInstanceOfferingAction.cpuNum = 1;
createInstanceOfferingAction.memorySize = 2148000000l;
createInstanceOfferingAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
InstanceOfferingInventory instanceOffering = createInstanceOfferingAction.call().value.inventory;

场景10 添加镜像（Image）

到这里，只剩下云主机启动的镜像没有添加了，镜像为云主机文件系统提供模板。镜像可以是为云主机安装操作系统的根云盘（root volume）提供模板的RootVolumeTemplate；镜像也可以是为云主机存储非操作系统数据的数据云盘（data volumes）提供模板的DataVolumeTemplate；同时镜像也可以是用来在空白根云盘（blank root volumes）上安装操作系统的ISO文件。

//添加镜像到本地镜像仓库
AddImageAction addImageAction = new AddImageAction();
addImageAction.name = "image1";
addImageAction.url = "http://192.168.200.100/mirror/diskimages/centos7.2-mini-qemu-qa.qcow2";
addImageAction.format = "qcow2";
addImageAction.backupStorageUuids = "15a01470b6fb4468b64b62ae58eb22c0";
addImageAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
ImageInventory image = addImageAction.call().value.inventory;

场景11 创建云主机（VM instance）

当所有资源准备就绪，我们可以开始创建云主机了。

//创建虚拟机
CreateVmInstanceAction createVmInstanceAction = new CreateVmInstanceAction();
createVmInstanceAction.name = "vm1";
createVmInstanceAction.instanceOfferingUuid = "416ba9d9365643bbbe18c8ed2dca2e2c";
createVmInstanceAction.imageUuid = "0403f3b539cf49b68cecdb0b5da92b8b";
createVmInstanceAction.l3NetworkUuids = "917fe2f51ab7423ca6e74648c5ae8931";
createVmInstanceAction.dataDiskOfferingUuids = "c87fea8ea690429a8825a9bf9fa68b4d";
createVmInstanceAction.clusterUuid = "db2e569c4e2c41448fb6f9309d2bf52f";
createVmInstanceAction.description = "this is a vm";
createVmInstanceAction.sessionId = "68a05a0154d4472bb7a059b54a53f166";
VmInstanceInventory vm = createVmInstanceAction.call().value.inventory;

其中，每个所依赖资源的uuid都通过对应资源的Inventory获取

场景12 创建快照（Snapshot）

云主机运行起来后，用户为了保证数据的安全性，可以为云主机做快照备份。快照可以保存云主机的根云盘（Root Volume）或者数据云盘（Data Volume）在某一时刻的所有数据。根云盘和数据云盘创建快照使用的是相同的API。

CreateVolumeSnapshotAction action = new CreateVolumeSnapshotAction();
action.volumeUuid = "5d7edc10db7b4187a27e310bac3d3201";
action.name = "snapshot-volume";
action.description = "a snapshot for volume";
action.sessionUuid = "68a05a0154d4472bb7a059b54a53f166";
CreateVolumeSnapshotAction.Result res = action.call();

场景13 修改云主机配置（Instance Offering）

当用户的业务量增加，需要调整CPU,内存，网络IO，硬盘IO时，可以通过该方式生效。需要注意的是，在目前版本中，需要停止云主机，再启动云主机，才能读取修改后的配置。

UpdateVmInstanceAction action = new UpdateVmInstanceAction();
action.uuid = "6cff485bf490471bb64a9f2824aca8d6";
action.name = "new vm name";
action.sessionUuid = "68a05a0154d4472bb7a059b54a53f166";
UpdateVmInstanceAction.Result res = action.call();

场景14 调用Console访问接口（Request Console Access）

用户可以通过前端代码调用Console访问接口，获取云主机Console界面的信息，在前端页面打开云主机的Console界面。

RequestConsoleAccessAction action = new RequestConsoleAccessAction();
action.vmInstanceUuid = "6cff485bf490471bb64a9f2824aca8d6";
action.sessionUuid = "68a05a0154d4472bb7a059b54a53f166";
RequestConsoleAccessAction.Result res = action.call();

当调用该接口获得云主机console的访问信息后，可以通过如下javascript示例代码在前端页面打开云主机的Console访问：

     $window.open("personal_dir/vnc.html?host=" + hostname +
         "&port=" + port + 
         "&token=" +token +
         "&title=" + name)

其中，hostname, port, token是通过API返回的Console访问信息res获得的，name是用户自定义的名称，不做限制。

场景15 获取用户资源配额（Quota）

当业务规模不断扩大，管理员可以创建不同的账户，并且给账户分配不同的配额。管理员可以根据账户的uuid获得账户对当前资源的使用配额。

QueryQuotaAction action = new QueryQuotaAction();
action.conditions = asList("name=test");
action.sessionUuid = "68a05a0154d4472bb7a059b54a53f166";
QueryQuotaAction.Result res = action.call();

第二章特定场景操作

了解了ZStack基本的资源创建操作方法后，本章将给读者展示如何基于已有的知识，快速创建不同场景下的私有云环境。

本章节的各类场景将覆盖以下资源：
网络类型覆盖扁平网络，云路由网络；
主存储类型覆盖本地存储，ceph分布式存储，NFS
备份存储类型覆盖镜像仓库，ceph分布式存储

由于以下场景为笔者模拟的网络环境，公网IP段并非真实公网IP段，请读者根据实际网络环境调整

用户场景1： ZStack构建常见私有云架构

该类场景通常内部有一个私有网络段，对外有一个公有网络段，但公有网络IP地址有限，需要作为弹性IP分配给云平台的云主机使用。同时，客户的运维团队不希望运维分布式存储，希望通过RAID阵列卡来对磁盘做冗余，解决存储安全的问题。在这种场景下，ZStack提供的私有云方案如下：
网络类型：扁平网络+弹性IP
主存储类型：本地存储
备份存储：镜像服务器
公有网络：公网地址段（弹性IP）
私有网络：内网地址段（云主机之间通讯使用）

网络拓扑图如下：
cmd-markdown-logo

在上图中，我们可以看到三个网络，分别连接了ZStack管理节点，物理服务器，镜像服务器。 ZStack管理节点通过192.168.0.0/24的网络连接并控制物理服务器和镜像服务器。物理服务器上的云主机则通过192.168.100.0/24的网络进行数据交换，并通过公有网络10.0.0.0/8获取弹性IP，透过企业的防火墙访问Internet，并支持外部访问绑定了弹性IP的云主机。
这种场景的优势在于，部署简单，成本较低，用户的设备可以利旧，并且分布式网络架构保证了云平台的网络不会出现单点故障。

通过Java SDK创建该私有云环境的代码如下：

package org.zstack.scene;
import org.zstack.sdk.*;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.Collections;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import static java.util.Arrays.asList;
/**

 */
public class flatNetworkLocalStorageEipScene {
    public static String SHA(final String strText, final String strType){
        String strResult = null;
        if (strText != null && strText.length() > 0) {
            try {
                // SHA 加密开始
                // 创建加密对象 并传入加密类型
                MessageDigest messageDigest = MessageDigest.getInstance(strType);
                // 传入要加密的字符串
                messageDigest.update(strText.getBytes());
                // 得到 byte 类型结果
                byte byteBuffer[] = messageDigest.digest();
                // 将 byte 转换为 string
                StringBuffer strHexString = new StringBuffer();
                // 遍历 byte buffer
                for (int i = 0; i < byteBuffer.length; i++)
                {
                    String hex = Integer.toHexString(0xff & byteBuffer[i]);
                    if (hex.length() == 1)
                    {
                        strHexString.append('0');
                    }
                    strHexString.append(hex);
                }
                // 得到返回结果
                strResult = strHexString.toString();
            }
            catch (NoSuchAlgorithmException e)
            {
                e.printStackTrace();
            }
        }

用户场景2： ZStack整合分布式存储

在该场景下，用户内部业务部门对数据安全性的要求很高，不希望产生数据丢失的情况，并希望使用业界流行的超融合架构，即每个物理机均提供网络、存储、计算的功能。用户提供一个网关，所有云主机能够和该网关下其他设备能够直接通讯。在这种场景下，ZStack提供的私有云方案如下：

网络类型：扁平网络
主存储类型：ceph分布式存储
备份存储： ceph分布式存储
私有网络：内网地址段（云主机使用）

网络拓扑图如下：
分布式存储

这种模式也需要用户拥有万兆的网络环境，而在ZStack中搭建分布式存储网络模型，则和NAS架构相比，仅需在添加主存储时，选择使用Ceph，并且指定192.168.0.0/24网段Ceph的MonURLs。

使用Ceph的好处有：成本相对低廉（完全使用免费开源软件搭建，且不考虑聘请额外的Ceph运维人员），数据“没有”单点故障（要求运维良好），数据相对安全（多副本存储于不同的机器）。注意到当前市场上以有一部分公司都已经在生产环境中使用了Ceph。不过考虑到目前的市场反馈，保证Ceph稳定性，如果中小公司打算采用Ceph方案，也可以通过ZStack获得商业级ceph存储。

另外，细心的读者可能会问，我们为什么图中使用计算和存储分离的Ceph架构，而不是计算和存储融合的架构。这个地方主要也是考虑到Ceph在大IO（例如计算节点上云主机较多，且IO操作比较频繁）的时候，会消耗大量的物理机CPU。如果采用融合的架构，如果不进行有效的隔离，可能会导致云主机的效率降低。当然，具体采用何种分布式架构，还需要客户根据自己的场景来进行规划。

通过Java SDK创建该私有云环境的代码如下：

用户场景3： ZStack整合云路由构建VPC

在该场景下，用户内部的业务部门较多，每个业务部门希望自己的网络环境是完全隔离的，不受其他业务部门影响，该私有云环境更多的运行各业务部门对内的系统，例如OA系统、开发系统、测试系统等。在这种场景下，ZStack提供的私有云方案如下：
网络类型：云路由
主存储类型：本地存储
备份存储：镜像仓库
私有网络：内网地址段（云主机之间通讯使用）
公有网络：云主机弹性IP使用的网络段
管理网络：和云路由、物理机、备份存储等资源通信的网络

网络拓扑图如下：
cmd-markdown-logo

这种场景下，每个云路由内部的云主机之间可以相互通信，跨云路由的云主机之间无法直接通讯，需要通过弹性IP相互通讯。在创建该场景的过程中，需要显示的创建管理网络，并设置网络类型为“无服务网络”，这样做的原因在于创建云路由规格时，需要显示的添加云路由的管理网络，否则，云路由将不知道如何和管理节点通讯。
这种场景的好处在于，每个业务部门之间的网络完全隔离，并且，云路由能够提供更多的网络增值服务，例如，端口转发，负载均衡。

通过Java SDK创建该私有云环境的代码如下：

用户场景4： ZStack整合NAS商业存储

用户预算较多，购买了商业存储，希望在一个集中式的NAS存储上，使用私有云
用户是一个学校或较大规模的企业，已经在过去的IT基础设施中采用的商业NAS存储，在使用私有云的过程中，更希望能够对已有设备利旧，同时，对商业存储的信赖度较高，希望整个私有云的环境能够部署在商业存储上。在这种场景下，ZStack提供的私有云方案如下：
网络类型：扁平网络
主存储类型：NFS
备份存储：镜像仓库
私有网络：内网地址段（云主机使用）
管理网络：和云路由、物理机、备份存储等资源通信的网络
公共网络：云主机弹性IP使用的网络段
网络拓扑图如下：

用户在添加NAS存储的过程中，只需在选择主存储的时候，选择NFS的方式。另外由于使用了网络共享存储，云主机的磁盘IO访问都会通过网络访问NFS主存储。因此单一的数据网络很可能无法满足大量的磁盘读写请求。我们需要新划分一个存储网络（万兆）。为什么需要万兆呢？因为云主机的云盘都是放在NFS存储中，如果只是千兆的网络环境，即使仅有一个云主机在进行磁盘操作，最多也只能使用到1gbps的带宽，理论磁盘读写的上限为125MB/s。考虑到多云主机以及网络传输效率，千兆网络将会极大的限制云主机的磁盘IO性能。

在使用存储网络的时候，我们需要先将物理服务器，NFS主存储，镜像服务器，管理节点上空闲的网卡连接到新的存储网络，并且配置存储网络的IP地址（例如192.168.100.0/24网段）。在添加NFS主存储和镜像服务器的时候，使用这些IP地址即可。

该场景的优势是，计算和存储分离。云主机可以在线迁移，一旦计算节点失效，云主机可以快速恢复。商业NFS主存储在数据的高可靠、高可用、性能方面都有较好的表现。
