<h1 id="配置请求的路由规则">配置请求的路由规则</h1>
|
||
<p>在上一节<a href="istio-installation.html">安装istio</a>中我们创建<a href="https://istio.io/docs/samples/bookinfo.html" target="_blank">BookInfo</a>的示例，熟悉了Istio的基本功能，现在我们再来看一下istio的高级特性——配置请求的路由规则。</p>
|
||
<p>使用istio我们可以根据<strong>权重</strong>和<strong>HTTP headers</strong>来动态配置请求路由。</p>
|
||
<h2 id="基于内容的路由">基于内容的路由</h2>
|
||
<p>因为BookInfo示例部署了3个版本的评论微服务，我们需要设置一个默认路由。 否则，当你多次访问应用程序时，会注意到有时输出包含星级，有时候又没有。 这是因为没有明确的默认版本集，Istio将以随机方式将请求路由到服务的所有可用版本。</p>
|
||
<p><strong>注意</strong>：假定您尚未设置任何路由。如果您已经为示例创建了冲突的路由规则，则需要在以下命令中使用replace而不是create。</p>
|
||
<p>下面这个例子能够根据网站的不同登陆用户，将流量划分到服务的不同版本和实例。跟kubernetes中的应用一样，所有的路由规则都是通过声明式的yaml配置。关于<code>reviews:v1</code>和<code>reviews:v2</code>的唯一区别是，v1没有调用评分服务，productpage页面上不会显示评分星标。</p>
|
||
<ol>
|
||
<li><p>将微服务的默认版本设置成v1。</p>
|
||
<pre><code>istioctl create -f samples/apps/bookinfo/route-rule-all-v1.yaml
|
||
</code></pre><p>使用以下命令查看定义的路由规则。</p>

|
||
<p>由于对代理的规则传播是异步的，因此在尝试访问应用程序之前，需要等待几秒钟才能将规则传播到所有pod。</p>

</li>
|

<li><p>在浏览器中打开BookInfo URL（<a href="http://$GATEWAY_URL/productpage，我们在上一节中使用的是" target="_blank">http://$GATEWAY_URL/productpage，我们在上一节中使用的是</a> <a href="http://ingress.istio.io/productpage" target="_blank">http://ingress.istio.io/productpage</a> ）您应该会看到BookInfo应用程序的产品页面显示。 注意，产品页面上没有评分星，因为<code>reviews:v1</code>不访问评级服务。</p>
|
||
</li>
|
||
<li><p>将特定用户路由到<code>reviews:v2</code>。</p>
|
||
<p>为测试用户jason启用评分服务，将productpage的流量路由到<code>reviews:v2</code>实例上。</p>
|
||
<pre><code>istioctl create -f samples/apps/bookinfo/route-rule-reviews-test-v2.yaml
|

|

<pre><code>istioctl get route-rule reviews-test-v2

</code></pre>
|
||
</li>
|
||
<li><p>使用jason用户登陆productpage页面。</p>
|
||
<p>你可以看到每个刷新页面时，页面上都有一个1到5颗星的评级。如果你使用其他用户登陆的话，将因继续使用<code>reviews:v1</code>而看不到星标评分。</p>
|
||
</li>
|
||
</ol>
|
||
<h2 id="内部实现">内部实现</h2>
|
||
<p>在这个例子中，一开始使用istio将100%的流量发送到BookInfo服务的<code>reviews:v1</code>的实例上。然后又根据请求的header（例如用户的cookie）将流量选择性的发送到<code>reviews:v2</code>实例上。</p>
|
||
<p>验证了v2实例的功能后，就可以将全部用户的流量发送到v2实例上，或者逐步的迁移流量，如10%、20%直到100%。</p>
|
||
<p>如果你看了<a href="https://istio.io/docs/tasks/fault-injection.html" target="_blank">故障注入</a>这一节，你会发现v2版本中有个bug，而在v3版本中修复了，你想将流量迁移到<code>reviews:v1</code>迁移到<code>reviews:v3</code>版本上，只需要运行如下命令：</p>
|
||
<ol>
|
||
<li><p>将50%的流量从<code>reviews:v1</code>转移到<code>reviews:v3</code>上。</p>
|
||
<pre><code>istioctl replace -f samples/apps/bookinfo/route-rule-reviews-50-v3.yaml
|
||
</code></pre><p>注意这次使用的是<code>replace</code>命令，而不是<code>create</code>，因为该rule已经在前面创建过了。</p>
|
||
</li>
|
||
<li><p>登出jason用户，或者删除测试规则，可以看到新的规则已经生效。</p>
|
||
<p>删除测试规则。</p>
|
||
<pre><code>istioctl delete route-rule reviews-test-v2
|
||
istioctl delete route-rule ratings-test-delay
|
||
</code></pre><p>现在的规则就是刷新<code>productpage</code>页面，50%的概率看到红色星标的评论，50%的概率看不到星标。</p>
|
||
<p>注意：因为使用Envoy sidecar的实现，你需要刷新页面很多次才能看到接近规则配置的概率分布，你可以将v3的概率修改为90%，这样刷新页面时，看到红色星标的概率更高。</p>
|
||
</li>
|
||
<li><p>当v3版本的微服务稳定以后，就可以将100%的流量分摊到<code>reviews:v3</code>上了。</p>
|
||
<pre><code>istioctl replace -f samples/apps/bookinfo/route-rule-reviews-v3.yaml
|
||
</code></pre><p>现在不论你使用什么用户登陆<code>productpage</code>页面，你都可以看到带红色星标评分的评论了。</p>
