Kubernetes 如何将头添加到从源Pod到目标Pod的每个请求中？

我正在尝试部署此处描述的BookInfo应用程序：

根据本教程，我正在基于标题“最终用户：jason”来路由请求

根据本教程，product Microservices会在您登录后添加一个请求头“end-user:jason”

我希望它在任何情况下都能发出这个标题。换句话说，对于从产品微服务发出的所有请求，我希望附加此头，而不管请求到达何处

我怎样才能做到这一点

我根据下面给出的建议创建了以下内容。出于某种原因，流量一直都会流向产品的两个版本。这是我所有的配置

正如评论中提到的，他想部署2个productpage应用程序

• 第一条路线仅用于查看v1
• 第二条路线仅用于查看v2

所以我使用istio文档中的productpage进行了快速测试，您必须配置虚拟服务和目标规则才能实现

---

安装 部署和服务

kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.5/samples/bookinfo/platform/kube/bookinfo.yaml

网关与虚拟服务

kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.5/samples/bookinfo/networking/bookinfo-gateway.yaml

---

如上所述 在使用Istio控制Bookinfo版本路由之前，您需要在目标规则中定义称为子集的可用版本

如果未启用相互TLS，请执行以下命令：

如果确实启用了相互TLS，请执行以下命令：

---

然后简单地添加虚拟服务 您可以像在本文中一样使用每个微服务的v1，也可以只查看v1

因此，对于每个使用v1的微服务来说

kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.5/samples/bookinfo/networking/virtual-service-all-v1.yaml

只是为了复习v1

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: reviews
spec:
  hosts:
  - reviews
  http:
  - route:
    - destination:
        host: reviews
        subset: v1

这就是第一个productpage应用程序需要做的一切

---

第二个productpage应用程序 您必须对第二个进行完全相同的操作，这里唯一的更改是虚拟服务以匹配子集v2，当然，如果您想要部署这两个，我建议使用2个名称空间并将它们分开，在虚拟服务、部署、网关等中更改名称空间

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: reviews
spec:
  hosts:
  - reviews
  http:
  - route:
    - destination:
        host: reviews
        subset: v2

---

标题 如中所述，您可以使用

请求头->将请求转发到目标服务之前要应用的操作规则

或

响应头->将响应返回给调用方之前要应用的操作规则

我不完全确定您需要什么，这显示了如何为每个请求添加响应头，您可以在虚拟服务中添加响应头。有关更多信息，请参见下面的示例链接

我根据您添加的图片创建了这个虚拟服务，因此每次您以jason身份登录时，它都会将您重定向到产品v2并查看v2，默认情况下，我会保留评级和详细信息v1

我知道了

感谢@jt97对我的帮助

请按照此处的所有步骤进行操作：

按照此处提供的设置虚拟服务：

kubectl应用-f

添加产品v2部署配置以创建pod产品v2

修改产品的destinationrule和virtualservices以适应v1和v2

现在，修改virtualservices以供查看，并使用sourceLabels指定它应该如何路由

整个配置如下所示：

在这里，sourceLabels是关键。我们基本上是说所有来自标签为“version:v2”的源的流量都应该路由到reviews v2

因此，每次点击时，它都会将50%的流量分别路由到产品v1和产品v2

来自产品v1的流量路由到review v1，来自产品v2的流量路由到review v2

这就是它现在的样子：

我不确定我是否理解正确，但我认为在虚拟服务中简单的

标题：响应：添加：

就足够了。检查此项，并让我知道这是否是我们正在寻找的，或者您需要其他东西。我想解决此问题：我想部署两套产品和审阅服务v1和v2。v1产品应达到v1审查和v2的类似要求。你能帮我实现这一点吗？基于istio示例，它有1个产品页面，可以路由到3个评论，你想创建2个产品页面，第一个产品页面将路由到评论v1，第二个产品页面将路由到评论v2？或者您想添加标题，并基于标题控制是否应该转到review v1/v2？“第一个产品页将仅路由到review v1，第二个产品页将仅路由到review v2”最终，这一个。如果我能够将头添加到所有出站HTTP请求中，那么这个示例已经谈到了基于头的路由。@jt97我已经用我想要的图表更新了这个问题。感谢您的快速响应。我需要在同一命名空间上部署两组版本。我尝试按照您提到的步骤进行操作，但使用的名称空间相同。最终结果是Review V1或V2正在为请求提供服务。我希望所有的版本集都部署在同一个名称空间上，这可能吗？就我所知，在同一个名称空间中可能不可能这样做，因为网关、虚拟服务、目标规则会相互干扰。就我而言，名称空间将给您某种“隔离”。我很担心，因为它是同一个应用程序，具有相同的前缀和所有内容，我不确定它将如何工作。为什么您不使用productpage的一个版本，并在虚拟服务中使用标题将其路由到特定版本的评论？是的，这是我最初的想法。当Product V2调用Review时，是否有方法拦截http请求并向请求添加标题“x-end-user:jason”？这将解决我的问题，我想。检查我的答案中的编辑，希望它是你需要的。谢谢你的编辑。我已经做了必要的工作，但流量仍将进入两个版本。我有一个
