在ASM实例关联的集群中部署应用_服务网格(ASM)-阿里云帮助中心

为ASM实例添加入口网关后，您可以部署应用到该实例关联的集群。本文介绍如何将Bookinfo书评应用部署到ASM实例关联的ACK集群。

前提条件

已创建至少一个ASM实例，并添加至少一个ACK集群到该实例中。具体操作，请参见创建ASM实例和添加集群到ASM实例。
已通过Kubernetes命令行客户端kubectl连接到ASM实例中新添加的ACK集群。具体操作，请参见获取集群KubeConfig并通过kubectl工具连接集群。
已为ACK集群创建入口网关，使应用示例对外暴露访问。具体操作，请参见创建入口网关。

应用说明

本文所使用应用示例是一个名为Bookinfo的书评应用。微服务架构如下图所示：

该应用由以下4个微服务构成：

Productpage：该微服务会调用Details和Reviews两个微服务，用来生成页面。
Details：该微服务包含了书籍的信息。
Reviews：该微服务包含了书籍相关的评论，同时会调用Ratings微服务。
Ratings：该微服务包含了由书籍评价组成的评级信息。

Reviews微服务有3个版本：

v1版本不会调用Ratings服务。
v2版本会调用Ratings服务，并使用1到5个黑色星形图标来显示评分信息。
v3版本会调用Ratings服务，并使用1到5个红色星形图标来显示评分信息。

操作步骤

为default命名空间启用Sidecar网格代理自动注入。具体操作，请参见启用自动注入。

使用以下内容创建bookinfo.yaml。

通过kubectl执行以下命令，将Bookinfo应用部署到ASM实例关联的集群中。
```
kubectl apply -f bookinfo.yaml
```
查看Bookinfo应用的部署情况。
1. 登录容器服务管理控制台，在左侧导航栏选择集群列表。
2. 在集群列表页面，单击目标集群名称，然后在左侧导航栏，选择工作负载 > 容器组。
3. 在容器组页面，从命名空间下拉列表中选择default，查看Bookinfo应用部署所对应的Pod信息。
  说明
  您可以单击对应Pod操作列的详情，查看Pod的详细信息。

后续操作

您可以创建网关规则和虚拟服务，通过ASM网关对服务进行访问，还可以创建目标规则，将流量按照比例路由到服务的不同版本。具体操作，请参见使用Istio资源实现版本流量路由。
