+Dubbo's consumer directly discovers the corresponding service endpoints of kubernetes during service discovery procedure, thereby reusing Dubbo's existing microservice channel capabilities.The benefit is that there is no need to rely on any third-party soft-loaded registry and it can be seamlessly integrated into the multi-tenant security system of kubernetes.

+<h1>Introduction</h1>
+<p>Kubernates is a hierarchical system with rich secondary development function based on the expansibility.</p>
+<ul>
+<li>First of all, Kubernates's core function is to manage the container cluster. Kubernates manages the  storage and calculation of containerized cluster, based on the container runtime (CRI), network interface (CNI) and storage service interface (CSI/FV).</li>
+<li>Secondly,Kubernates has application-oriented deployment and routing capabilities,including statefulness/statelessness,batch processing and service-oriented applications,especially the application management based on microservices architecture which includes service discovery,service definition and unified configuration on the basis of configmap.</li>
+<li>Finally, on top of the abstract model of the basic resource (mainly the resources of abstract infrastructure, IaaS) and the application layer is the governance layer, which includes elastic expansion, namespaces/tenants and so on. Naturally, it is a matter of course to set up service about unified log center and omnidirectional monitoring on the Kubernetes based upon the foundational capabilities of atomic inner core.</li>
+</ul>
+<p>We will explain the above description with a diagram of Kubernetes Architecture. In 2018, Kubernetes took a qualitative step toward the standard PaaS basement.Someone hold opinions that the reason is the ability for secondary development on the basis of the expansion and someone think the key is declarative programming and strong community operations relying on Google and Redhat. However,I think the essential reason is Layered architecture and the abstract domain modeling in the probl [...]

+<p>From a micro-service architecture perspective, Kubernetes is a micro-service framework (more appropriate than a micro-service platform or toolkit set at this time) in a sense, supporting the basic capabilities of microservices for service discovery/registration. Use the following table to make a brief description.</p>

+<p>By the way, the microservices field involves many issues, which can be explained as follows. When building microservices, we will delve into Distributed System, a discipline has a 40-year research background and is rooted in the adaptive system theory. It's a bit complicated, but the concepts it covers are more or less heard for us, and it solves problems that we're familiar with:</p>
+<ul>
+<li>Deployment</li>
+<li>Delivery</li>
+<li>APIs</li>
+<li>Versioning</li>
+<li>Contracts</li>
+<li>Scaling / Autoscaling</li>
+<li>Service Discovery</li>
+<li>Load Balancing</li>
+<li>Routing / Adaptive Routing</li>
+<li>Health Checking</li>
+<li>Configuration</li>
+<li>Circuit Breaking</li>
+<li>Bulk-heads</li>
+<li>TTL / Deadlining</li>
+<li>Latency Tracing</li>
+<li>Service Causal Tracing</li>
+<li>Distributed logging</li>
+<li>Metrics Exposure, Collection</li>
+</ul>
+<p>For Kubernetes, only a few of problems are solved. Problems such as Dynamic Routing, Stability Control (Circuit Breaking, Bulk-heads, etc.) , Distributed Service Tracking, etc. are all the blank. These problems are exactly what Service Mesh needs to solve, and these also plays an important role in CNCF's Tail Map. Of course, as Dubbo is a basically complete microservices infrastructure (Dubbo is based on the Sidecar which is a common solution for solving cross-language claims in Servi [...]

It's responsible for the reliable delivery of requests through the complex topology of services that comprise a modern, cloud native application.</span></span></p>
+</blockquote>
+<p>We will know the existing solution, Dubbo integrates the Clould Native Equipment - Kubernetes's basic abilities to solve the microservices's core problems, can be regarded as a Service Mesh solution in a narrow sense, but it can only be used in the Java field. You can understand the above words as a joke, haha.</p>

+<p>Kubernetes is a natural address registration center for microservices, similar to zookeeper, VIPserver and Configserver used internally by Alibaba. Specifically, the Pod in kubernetes is a running instance of the application. The scheduled deployment/start/stop of the Pod will call the API-Server service to maintain its state to ETCD. The service in kubernetes is coresponded to the concept of the microservices defined as follows.</p>
+<blockquote>
+<p>A Kubernetes Service is an abstraction layer which defines a logical set of Pods and enables external traffic exposure, load balancing and service discovery for those Pods.</p>
+</blockquote>
+<p>In conclusion, the kubernetes service has the following characteristics:</p>
+<ul>
+<li>Each Service has a unique name and corresponding IP. IP is automatically assigned by kubernetes and the name is defined by the developer.</li>
+<li>Service IP has several manifestations: ClusterIP, NodePort, LoadBalance and Ingress. ClusterIP is mainly used for intra-cluster communication; NodePort, Ingress and LoadBalance, which are used to expose services to access portals outside the cluster.</li>
+</ul>
+<p>At first sight, the service of kubernetes has its own IP, while under the original fixed mindset: Dubbo/HSF service is aggregated by the IP of the entire service cluster, that means, kubernetes and Dubbo/HSF look like something different in natural, but when carefully thinking, the difference becomes insignificant. Because the only IP under kubernetes is just a Virtural IP--VIP, behind the vip are multiple endpoints, which is the factual processing node.</p>
 <p>Here we only discuss the situation that the Dubbo service in the cluster is accessed in the same kubernetes cluster, As for the provider outside kubernetes to access the provider in kubernetes, since it involves the problem of network address space, and it usually requires GateWay/loadbalance for mapping conversion, which there not detail discussion for this case. Besides, there are two options available for kubernetes:</p>

 <p>You can run Demo Provider and Demo Consumer only, the default discovery strategy is Multicast by configuration center broadcast, do not run the two parts on the same machine, if you have to do so, set <code>unicast=false</code>, like <code>multicast://224.5.6.7:1234?unicast=false</code>, or the unicast send to consumer will be taken by provider, and the same for consumers. Only multicast has this issue</p>
 <p>You can run multiple Demo Provider and Demo consumer to verify load balance. Demo Consumer can run multi instance directly. Because of port conflict, you can either run multi Demo Providers on different machines or modify the value of <code>dubbo.protocol.port</code> in <code>conf/dubbo.properties</code> under the install directory of <code>conf/dubbo.properties</code></p>
 <p>You can add Simple Monitor as a monitor center, the default discovery strategy is Multicast by configuration center broadcast, display the dependency relationship, call times and cost</p>
 <p>You can use Zookeeper instead of Multicast as the configuration center, after Zookeeper Registry installation, modify <code>conf/dubbo.properties</code> under the installation directory of Demo Provider, Demo Consumer and Simple Monitor, change the value of <code>dubbo.registry.address</code> to <code>zookeeper://127.0.0.1:2181</code>(<code>redis://127.0.0.1:6379</code> for Redis Registry). the value for Simple Registry is <code>dubbo://127.0.0.1:9090</code></p>
 <p>Zookeeper configuration address is recommended</p>

 <p>After using Dubbo to serve or integrate applications, assuming that a service backstage log shows an exception and that the service is invoked by multiple applications, it is often difficult to determine which application is called, and what is the cause of the problem, so we need a set of distributed tracking systems to quickly locate the problem. Pinpoint can help us quickly locate problems (of course, there are more than one solution).</p>
 <h2>What is Pinpoint</h2>
 <p><a href="https://github.com/naver/pinpoint">Pinpoint</a> is an APM (Application Performance Management) tool for large-scale distributed systems written in Java. Inspired by Dapper, Pinpoint provides a solution to help analyze the overall structure of the system and how components within them are interconnected by tracing transactions across distributed applications.</p>

 <p>Dubbo's protocol, communication, serialization, registry, load balancing and other SPI all offer alternative strategies for different application scenarios while our test cases are very scattered. Ours is always uncertain whether it can satisfy the complete contract of the extension point when users need to add a new implementation.</p>
 <p>Thus we need to use TCK (Technology Compatibility Kit) for the core extension points.  When users add a new implementaion, compatibility with the rest of the framework can be ensured with TCK. This can effectively improve the overall health and also facilitate the access of the third party extenders, which accelerates the maturity of the open source community.</p>
 <p>Xingzhi from the open source community is already working on this part. His preliminary idea is to build a TCK framework for Dubbo drawing on the CDI-TCK of JBoss first, then realize the TCK implementing case of Dubbo.</p>

 <h4>Monolithic architecture</h4>
@@ -23,7 +23,7 @@
 <p>When there are more and more vertical applications, the interaction between applications is inevitable, some core businesses are extracted and served as independent services, which gradually forms a stable service center,this way the front-end application can respond to the changeable market demand more quickly. At this point, the distributed service framework (RPC) for business reuse and integration is the key.</p>
 <h4>Flow computing architecture</h4>
 <p>When there are more and more services, capacity evaluation becomes difficult, and also services with small scales often causes waste of resources. To solve these problems, a scheduling center should be added to manage the cluster capacity based on traffics and to improve the utilization of the cluster. At this time, the resource scheduling and governance centers (SOA), which are used to improve machine utilization, are the keys.</p>

 <p>Before the advent of large-scare services, an application might just exposes or references remote service by using RMI or Hessian, the call is done by configuring serive URL, and load balance is done through hardwares, like F5.</p>
 <p><strong>When there are more and more services, it becomes very difficult to configure the service URL, the single point pressure of F5 hardware load balancer is also increasing.</strong> At this point, a service registry is needed to dynamically register and discover services to make the service's location transparent. By obtaining the list of service provider addresses in the consumer side, the soft load balancing and Failover can be realized, this reduces the dependence on the F5 ha [...]
 <p><strong>When things go further, the service dependencies become so complex that it can't even tell which applications to start before, even the architect can't fully describe the application architecture relationships</strong>. At this time, automatically draw the dependency diagram of the applications is needed to help the architect to be clear of the relationship.</p>
 <p><strong>Then, the traffic becomes even heavier, the capacity problem of the service is exposed, how many machines are needed to support this service? When should the machine be added?</strong> To solve these problems, first, the daily service calls and the amount of response time should be counted as a reference for capacity planning. Second, dynamically adjust the weight, increase the weight of an online machine, and recorded the response time changes until it reaches the threshold,  [...]
 <p>Above are the most basic requirements of Dubbo.</p>

+<h3>Port</h3>
+<p>the port of new version telnet is different from the port of dubbo protocol. The default port is <code>22222</code>, which can be changed by modifying configuration file <code>dubbo.properties</code></p>
+<pre><code>dubbo.application.qos.port=33333

 </code></pre>
-<p>Start:</p>
-<pre><code class="language-sh">./assembly.bin/start.sh

 <h2>背景</h2>
 <p>Dubbo是一个分布式服务框架,能避免单点故障和支持服务的横向扩容。一个服务通常会部署多个实例。如何从多个服务 Provider 组成的集群中挑选出一个进行调用,就涉及到一个负载均衡的策略。</p>
 <h2>几个概念</h2>

+<h2>Apache Skywalking(Incubator)简介</h2>
+<p><a href="https://github.com/apache/incubator-skywalking">Apache Skywalking(Incubator)</a> 专门为微服务架构和云原生架构系统而设计并且支持分布式链路追踪的APM系统。<a href="https://github.com/apache/incubator-skywalking">Apache Skywalking(Incubator)</a>通过加载探针的方式收集应用调用链路信息,并对采集的调用链路信息进行分析,生成应用间关系和服务间关系以及服务指标。<a href="https://github.com/apache/incubator-skywalking">Apache Skywalking (Incubating)</a>目前支持多种语言,其中包括<a href="https://github.com/apache/incubator-skywalking">Java</a>,<a href="https://github.com/OpenSkywalking/skyw [...]
+<p>目前Skywalking已经支持从6个可视化维度剖析分布式系统的运行情况。总览视图是应用和组件的全局视图,其中包括组件和应用数量,应用的告警波动,慢服务列表以及应用吞吐量;拓扑图从应用依赖关系出发,展现整个应用的拓扑关系;应用视图则是从单个应用的角度,展现应用的上下游关系,TopN的服务和服务器,JVM的相关信息以及对应的主机信息。服务视图关注单个服务入口的运行情况以及此服务的上下游依赖关系,依赖度,帮助用户针对单个服务的优化和监控;调用链展现了调用的单次请求经过的所有埋点以及每个埋点的执行时长;告警视图根据配置阈值针对应用、服务器、服务进行实时告警。</p>
+<h2>Dubbo与Apache Skywalking(Incubator)</h2>
+<h3>编写Dubbo示例程序</h3>
+<p>Dubbo实例程序已上传到<a href="https://github.com/SkywalkingTest/dubbo-trace-example">Github仓库</a>中。方便大家下载使用。</p>
+<h4>API工程</h4>
+<p>服务接口:</p>
+<pre><code>package org.apache.skywalking.demo.interfaces;
+
+public interface HelloService {
+	String sayHello(String name);
+}
+</code></pre>
+<h4>Dubbo服务提供工程</h4>
+<pre><code>package org.apache.skywalking.demo.provider;
+
+@Service(version = &quot;${demo.service.version}&quot;,
+	application = &quot;${dubbo.application.id}&quot;,
+	protocol = &quot;${dubbo.protocol.id}&quot;,
+	registry = &quot;${dubbo.registry.id}&quot;, timeout = 60000)

+		LockSupport.parkNanos(TimeUnit.SECONDS.toNanos(1));
+		return &quot;Hello, &quot; + name;
+	}
+
+}
+</code></pre>
+<h4>Consumer工程</h4>
+<pre><code>package org.apache.skywalking.demo.consumer;

+<h3>部署Apache Skywalking(Incubator)</h3>
+<p>Apache Skywalking(Incubator)共提供两种部署模式:单节点模式和集群模式,以下为单节点模式部署步骤,集群模式部署详情参考<a href="https://github.com/apache/incubator-skywalking/blob/master/docs/cn/Deploy-backend-in-cluster-mode-CN.md">文档</a>。</p>
+<h4>依赖第三方组件</h4>
+<ol>
+<li>JDK8+</li>
+<li>Elasticsearch 5.x</li>
+</ol>
+<h4>部署步骤</h4>
+<ol>
+<li>下载<a href="http://skywalking.apache.org/downloads/"> Apache Skywalking Collector</a></li>
+<li>部署ElasticSearch
+<ul>
+<li>修改elasticsearch.yml文件,并设置<code>cluster.name</code>设置成<code>CollectorDBCluster</code>。此名称需要和collector配置文件一致。</li>
+<li>修改ES配置<code>network.host</code>值,将<code>network.host</code>的值修改成<code>0.0.0.0</code>。</li>
+<li>启动Elasticsearch</li>
+</ul>
+</li>
+<li>解压并启动Skywalking Collector。运行<code>bin/startup.sh</code>命令即可启动Skywalking Collector</li>
+</ol>
+<h4>启动示例程序</h4>
+<p>在启动示例程序之前,执行编译打包的命令:</p>
+<pre><code>./mvnw clean package
+</code></pre>
+<h4>启动服务提供端</h4>
+<pre><code>java -jar -javaagent:$AGENT_PATH/skywalking-agent.jar -Dskywalking.agent.application_code=dubbo-provider -Dskywalking.collector.servers=localhost:10800 dubbo-provider/target/dubbo-provider.jar
+</code></pre>
+<h4>启动服务消费端</h4>
+<pre><code>java -jar -javaagent:$AGENT_PATH/skywalking-agent.jar -Dskywalking.agent.application_code=dubbo-consumer -Dskywalking.collector.servers=localhost:10800 dubbo-consumer/target/dubbo-consumer.jar

+<p>目前Skywalking已经支持从6个可视化维度剖析分布式系统的运行情况。总览视图是应用和组件的全局视图,其中包括组件和应用数量,应用的告警波动,慢服务列表以及应用吞吐量;拓扑图从应用依赖关系出发,展现整个应用的拓扑关系;应用视图则是从单个应用的角度,展现应用的上下游关系,TopN的服务和服务器,JVM的相关信息以及对应的主机信息。服务视图关注单个服务入口的运行情况以及此服务的上下游依赖关系,依赖度,帮助用户针对单个服务的优化和监控;调用链展现了调用的单次请求经过的所有埋点以及每个埋点的执行时长;告警视图根据配置阈值针对应用、服务器、服务进行实时告警。</p>
+<h2>Dubbo与Apache Skywalking(Incubator)</h2>
+<h3>编写Dubbo示例程序</h3>
+<p>Dubbo实例程序已上传到<a href="https://github.com/SkywalkingTest/dubbo-trace-example">Github仓库</a>中。方便大家下载使用。</p>
+<h4>API工程</h4>
+<p>服务接口:</p>
+<pre><code>package org.apache.skywalking.demo.interfaces;
+
+public interface HelloService {
+	String sayHello(String name);
+}
 </code></pre>
-<p>使用以下命令做一次构建</p>
-<pre><code class="language-sh">mvn clean install
+<h4>Dubbo服务提供工程</h4>
+<pre><code>package org.apache.skywalking.demo.provider;
+
+@Service(version = &quot;${demo.service.version}&quot;,
+	application = &quot;${dubbo.application.id}&quot;,
+	protocol = &quot;${dubbo.protocol.id}&quot;,
+	registry = &quot;${dubbo.registry.id}&quot;, timeout = 60000)
+public class HelloServiceImpl implements HelloService {
+
+	public String sayHello(String name) {
+		LockSupport.parkNanos(TimeUnit.SECONDS.toNanos(1));
+		return &quot;Hello, &quot; + name;
+	}
+
+}
 </code></pre>
-<p>可以通过以下的构建命令来跳过单元测试</p>
-<pre><code class="language-sh">mvn install -Dmaven.test.skip
+<h4>Consumer工程</h4>
+<pre><code>package org.apache.skywalking.demo.consumer;
+
+@RestController
+public class ConsumerController {
+
+	private static int COUNT = 0;
+
+	@Reference(version = &quot;${demo.service.version}&quot;,
+		application = &quot;${dubbo.application.id}&quot;,
+		url = &quot;dubbo://localhost:20880&quot;, timeout = 60000)
+	private HelloService helloService;
+
+	@GetMapping(&quot;/sayHello/{name}&quot;)
+	public String sayHello(@PathVariable(name = &quot;name&quot;) String name) {

+<h3>部署Apache Skywalking(Incubator)</h3>
+<p>Apache Skywalking(Incubator)共提供两种部署模式:单节点模式和集群模式,以下为单节点模式部署步骤,集群模式部署详情参考<a href="https://github.com/apache/incubator-skywalking/blob/master/docs/cn/Deploy-backend-in-cluster-mode-CN.md">文档</a>。</p>
+<h4>依赖第三方组件</h4>
+<ol>
+<li>JDK8+</li>
+<li>Elasticsearch 5.x</li>
+</ol>
+<h4>部署步骤</h4>
+<ol>
+<li>下载<a href="http://skywalking.apache.org/downloads/"> Apache Skywalking Collector</a></li>
+<li>部署ElasticSearch
+<ul>
+<li>修改elasticsearch.yml文件,并设置<code>cluster.name</code>设置成<code>CollectorDBCluster</code>。此名称需要和collector配置文件一致。</li>
+<li>修改ES配置<code>network.host</code>值,将<code>network.host</code>的值修改成<code>0.0.0.0</code>。</li>
+<li>启动Elasticsearch</li>
+</ul>
+</li>
+<li>解压并启动Skywalking Collector。运行<code>bin/startup.sh</code>命令即可启动Skywalking Collector</li>
+</ol>
+<h4>启动示例程序</h4>
+<p>在启动示例程序之前,执行编译打包的命令:</p>
+<pre><code>./mvnw clean package
 </code></pre>
-<h2>IDE 支持</h2>
-<p>使用以下命令来生成 IDE 的工程</p>
-<h3>Intellij Idea</h3>
-<pre><code class="language-sh">mvn idea:idea
+<h4>启动服务提供端</h4>
+<pre><code>java -jar -javaagent:$AGENT_PATH/skywalking-agent.jar -Dskywalking.agent.application_code=dubbo-provider -Dskywalking.collector.servers=localhost:10800 dubbo-provider/target/dubbo-provider.jar
 </code></pre>
-<h3>eclipse</h3>
-<pre><code class="language-sh">mvn eclipse:eclipse
+<h4>启动服务消费端</h4>
+<pre><code>java -jar -javaagent:$AGENT_PATH/skywalking-agent.jar -Dskywalking.agent.application_code=dubbo-consumer -Dskywalking.collector.servers=localhost:10800 dubbo-consumer/target/dubbo-consumer.jar 
 </code></pre>
-<p>在 eclipse 中导入</p>
-<p>首先,需要在 eclipse 中配置 maven 仓库。通过 Preferences -&gt; Java -&gt; Build Path -&gt; Classpath 定义 <code>M2_REPO</code> 的 classpath 变量指向本地的 maven 仓库。 <sup class="footnote-ref"><a href="#fn2" id="fnref2">[2]</a></sup></p>
-<p>也可以通过以下的 maven 命令配置:</p>
-<pre><code class="language-sh">mvn eclipse:configure-workspace -Declipse.workspace=/path/to/the/workspace/

 <p>Dubbo 的协议,通讯,序列化,注册中心,负载均策等扩展点,都有多种可选策略,以应对不同应用场景,而我们的测试用例很分散,当用户自己需要加一种新的实现时,总是不确定能否满足扩展点的完整契约。</p>
 <p>所以,我们需要对核心扩展点写 <a href="http://en.wikipedia.org/wiki/Technology_Compatibility_Kit">TCK</a> (Technology Compatibility Kit),用户增加一种扩展实现,只需通过 TCK,即可确保与框架的其它部分兼容运行,可以有效提高整体健状性,也方便第三方扩展者接入,加速开源社区的成熟。</p>
 <p>开源社区的行知同学已着手研究这一块,他的初步想法是借鉴 JBoss 的 CDI-TCK,做一个 Dubbo 的 TCK 基础框架,在此之上实现 Dubbo 的扩展点 TCK 用例。</p>

 <p>前面不停的提到代码被其他人修改,这也开发人员要随时紧记的。这个其他人包括未来的自己,你要总想着这个代码可能会有人去改它。我应该给修改的人一点什么提示,让他知道我现在的设计意图,而不要在程序里面加潜规则,或埋一些容易忽视的雷,比如:你用 null 表示不可用,size 等于 0 表示黑名单,这就是一个雷,下一个修改者,包括你自己,都不会记得有这样的约定,可能后面为了改某个其它 BUG,不小心改到了这里,直接引爆故障。对于这个例子,一个原则就是永远不要区分 null 引用和 empty 值。</p>
 <h2>提高代码的可测性</h2>
 <p>这里的可测性主要指 Mock 的容易程度,和测试的隔离性。至于测试的自动性,可重复性,非偶然性,无序性,完备性(全覆盖),轻量性(可快速执行),一般开发人员,加上 JUnit 等工具的辅助基本都能做到,也能理解它的好处,只是工作量问题。这里要特别强调的是测试用例的单一性(只测目标类本身)和隔离性(不传染失败)。现在的测试代码,过于强调完备性,大量重复交叉测试,看起来没啥坏处,但测试代码越多,维护代价越高。经常出现的问题是,修改一行代码或加一个判断条件,引起 100 多个测试用例不通过。时间一紧,谁有这个闲功夫去改这么多形态各异的测试用例?久而久之,这个测试代码就已经不能真实反应代码现在的状况,很多时候会被迫绕过。最好的情况是,修改一行代码,有且只有一行测试代码不通过。如果修改了代码而测试�
 �例还能通过,那也不行,表示测试没有覆盖到。另外,可 Mock 性是隔离的基础,把间接依赖的逻辑屏蔽掉。可 Mock 性的一个最大的杀手就是静态方法,尽量少用。</p>

 <h2>配置向后兼容</h2>
 <p>向前兼容很好办,你只要保证配置只增不减,就基本上能保证向前兼容。但向后兼容,也是要注意的,要为后续加入新的配置项做好准备。如果配置出现一个特殊配置,就应该为这个“特殊”情况约定一个兼容规则,因为这个特殊情况,很有可能在以后还会发生。比如:有一个配置文件是保存“服务=地址”映射关系的,其中有一行特殊,保存的是“注册中心=地址”。现在程序加载时,约定“注册中心”这个Key是特殊的,做特别处理,其它的都是“服务”。然而,新版本发现,要加一项“监控中心=地址”,这时,旧版本的程序会把“监控中心”做为“服务”处理,因为旧代码是不能改的,兼容性就很会很麻烦。如果先前约定“特殊标识+XXX”为特殊处理,后续就会方便很多。</p>

 <p>这个是契约式设计的一部分,尽量遵守有返回值的方法是查询方法,void 返回的方法是命令。查询方法通常是幂等性的,无副作用的,也就是不改变任何状态,调 n 次结果都是一样的,比如 get 某个属性值,或查询一条数据库记录。命令是指有副作用的,也就是会修改状态,比如 set 某个值,或 update 某条数据库记录。如果你的方法即做了修改状态的操作,又做了查询返回,如果可能,将其拆成写读分离的两个方法,比如:User deleteUser(id),删除用户并返回被删除的用户,考虑改为 getUser() 和 void 的 deleteUser()。 另外,每个方法都尽量前置断言传入参数的合法性,后置断言返回结果的合法性,并文档化。</p>

+<p>一般的<code>dubbo</code>协议配置如下:</p>
+<pre><code class="language-xml">    ...
+    <span class="hljs-tag">&lt;<span class="hljs-name">dubbo:protocol</span> <span class="hljs-attr">name</span>=<span class="hljs-string">"dubbo"</span> <span class="hljs-attr">port</span>=<span class="hljs-string">"20890"</span> /&gt;</span>
+    ...
 </code></pre>
-</beans>
-```
+<p>可以看到,只配置了端口号,没有配置<code>host</code>,此时设置的<code>host</code>又是什么呢?
+查看代码发现,在<code>com.alibaba.dubbo.config.ServiceConfig#findConfigedHosts()</code>中,通过<code>InetAddress.getLocalHost().getHostAddress()</code>获取默认<code>host</code>.其返回值如下:</p>
 <ol>
-<li>
-<p>通过注册中心发现监控中心服务:</p>
-<pre><code class="language-xml"><span class="hljs-tag">&lt;<span class="hljs-name">dubbo:monitor</span> <span class="hljs-attr">protocol</span>=<span class="hljs-string">"registry"</span> /&gt;</span>
+<li>未联网时,返回127.0.0.1</li>
+<li>在阿里云服务器中,返回私有地址,如:172.18.46.234</li>
+<li>在本机测试时,返回公有地址,如:30.5.10.11</li>
+</ol>
+<h2>那在<code>dubbo</code>中如何指定服务的socket?</h2>
+<p>除此之外,可以通过<code>dubbo.protocol</code>或<code>dubbo.provider</code>的<code>host</code>属性对<code>host</code>进行配置,支持IP地址和域名,如下:</p>
+<pre><code class="language-xml">    ...
+    <span class="hljs-tag">&lt;<span class="hljs-name">dubbo:protocol</span> <span class="hljs-attr">name</span>=<span class="hljs-string">"dubbo"</span> <span class="hljs-attr">port</span>=<span class="hljs-string">"20890"</span> <span class="hljs-attr">host</span>=<span class="hljs-string">"www.example.com"</span>/&gt;</span>

+<p>见<a href="https://github.com/dubbo/dubbo-samples/tree/master/dubbo-samples-docker">dubbo通过环境变量设置host</a></p>
 <blockquote>
-<p>dubbo.properties</p>
+<p>有些部署场景需要动态指定服务注册的地址,如docker bridge网络模式下要指定注册宿主机ip以实现外网通信。dubbo提供了两对启动阶段的系统属性,用于设置对外通信的ip、port地址
+DUBBO_IP_TO_REGISTRY --- 注册到注册中心的ip地址
+DUBBO_PORT_TO_REGISTRY --- 注册到注册中心的port端口
+DUBBO_IP_TO_BIND --- 监听ip地址
+DUBBO_PORT_TO_BIND --- 监听port端口</p>
 </blockquote>
-<pre><code class="language-xml">dubbo.monitor.protocol=registry

-</li>
-<li>
-<p>暴露一个简单监控中心服务,但不注册到注册中心: (如果是用安装包,不需要自己写这个配置,如果是自己实现监控中心,则需要)</p>
-<pre><code class="language-xml"></code></pre>
-</li>
+<blockquote>
+<p>以上四个配置项均为可选项,如不配置dubbo会自动获取ip与端口,请根据具体的部署场景灵活选择配置。
+dubbo支持多协议,如果一个应用同时暴露多个不同协议服务,且需要为每个服务单独指定ip或port,请分别在以上属性前加协议前缀。 如:
+HESSIAN_DUBBO_PORT_TO_BIND hessian协议绑定的port
+DUBBO_DUBBO_PORT_TO_BIND   dubbo协议绑定的port
+HESSIAN_DUBBO_IP_TO_REGISTRY hessian协议注册的ip
+DUBBO_DUBBO_PORT_TO_BIND     dubbo协议注册的ip
+PORT_TO_REGISTRY或IP_TO_REGISTRY不会用作默认PORT_TO_BIND或IP_TO_BIND,但是反过来是成立的
+如设置PORT_TO_REGISTRY=20881 IP_TO_REGISTRY=30.5.97.6,则PORT_TO_BIND IP_TO_BIND不受影响
+如果设置PORT_TO_BIND=20881 IP_TO_BIND=30.5.97.6,则默认PORT_TO_REGISTRY=20881 IP_TO_REGISTRY=30.5.97.6</p>
+</blockquote>
+<h2>总结</h2>
+<ol>
+<li>可以通过<code>dubbo.protocol</code>或<code>dubbo.provider</code>的<code>host</code>属性对<code>host</code>进行配置,支持IP地址和域名.但此时注册到注册中心的IP地址和监听IP地址是同一个值</li>
+<li>为了解决在虚拟环境或局域网内consumer无法与provider通信的问题,可以通过环境变量分别设置注册到注册中心的IP地址和监听IP地址,其优先级高于<code>dubbo.protocol</code>或<code>dubbo.provider</code>的<code>host</code>配置</li>

 <p>在大规模服务化之前,应用可能只是通过 RMI 或 Hessian 等工具,简单的暴露和引用远程服务,通过配置服务的URL地址进行调用,通过 F5 等硬件进行负载均衡。</p>
 <p><strong>当服务越来越多时,服务 URL 配置管理变得非常困难,F5 硬件负载均衡器的单点压力也越来越大。</strong> 此时需要一个服务注册中心,动态的注册和发现服务,使服务的位置透明。并通过在消费方获取服务提供方地址列表,实现软负载均衡和 Failover,降低对 F5 硬件负载均衡器的依赖,也能减少部分成本。</p>
 <p><strong>当进一步发展,服务间依赖关系变得错踪复杂,甚至分不清哪个应用要在哪个应用之前启动,架构师都不能完整的描述应用的架构关系。</strong>  这时,需要自动画出应用间的依赖关系图,以帮助架构师理清理关系。</p>
 <p><strong>接着,服务的调用量越来越大,服务的容量问题就暴露出来,这个服务需要多少机器支撑?什么时候该加机器?</strong>  为了解决这些问题,第一步,要将服务现在每天的调用量,响应时间,都统计出来,作为容量规划的参考指标。其次,要可以动态调整权重,在线上,将某台机器的权重一直加大,并在加大的过程中记录响应时间的变化,直到响应时间到达阈值,记录此时的访问量,再以此访问量乘以机器数反推总容量。</p>
 <p>以上是 Dubbo 最基本的几个需求。</p>
