istio1.0.2配置
项目的组件相对比较复杂，原有的一些选项是靠 ConfigMap 以及 istioctl 分别调整的，现在通过重新设计的Helm Chart，安装选项用values.yml或者 helm 命令行的方式来进行集中管理了。
在安装 Istio 之前要确保 Kubernetes 集群（仅支持v1.9及以后版本）已部署并配置好本地的 kubectl 客户端。
1. 下载 Istio
$ wget https://github.com/istio/istio/releases/download/1.0.2/istio-1.0.2-linux.tar.gz $ tar zxf istio-1.0.2-linux.tar.gz $ cp istio-1.0.2/bin/istioctl /usr/local/bin/
2. 使用 Helm 部署 Istio 服务
git clone https://github.com/istio/istio.git cd istio
安装包内的 Helm 目录中包含了 Istio 的 Chart，官方提供了两种方法：
- 用 Helm 生成
istio.yaml，然后自行安装。 - 用
Tiller直接安装。
很明显，两种方法并没有什么本质区别，这里我们采用第一种方法来部署。
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system --set ingress.enabled=true --set sidecarInjectorWebhook.enabled=true --set ingress.service.type=NodePort --set gateways.istio-ingressgateway.type=NodePort --set gateways.istio-egressgateway.type=NodePort --set tracing.enabled=true --set servicegraph.enabled=true --set prometheus.enabled=true --set tracing.jaeger.enabled=true --set grafana.enabled=true --set kiali.enabled=true > istio.yaml $ kubectl create namespace istio-system $ kubectl create -f istio.yaml

这里说的是使用 install/kubernetes/helm/istio 目录中的 Chart 进行渲染，生成的内容保存到 ./istio.yaml 文件之中。将 sidecarInjectorWebhook.enabled 设置为 true，从而使自动注入属性生效。
部署完成后，可以检查 isotio-system namespace 中的服务是否正常运行：

- 过去的 istio-ca 现已更名
istio-citadel。 istio-cleanup-secrets是一个 job，用于清理过去的 Istio 遗留下来的 CA 部署（包括 sa、deploy 以及 svc 三个对象）。egressgateway、ingress以及ingressgateway，可以看出边缘部分的变动很大，以后会另行发文。
kubernetes 直接安装
kubectl apply -f install/kubernetes/helm/istio/templates/crds.yaml
kubectl apply -f install/kubernetes/istio-demo.yaml
3. Prometheus、Grafana、Servicegraph 和 Jaeger
等所有 Pod 启动后，可以通过 NodePort、Ingress 或者 kubectl proxy 来访问这些服务。比如可以通过 Ingress 来访问服务。
首先为 Prometheus、Grafana、Servicegraph 和 Jaeger 服务创建 Ingress：
$ cat ingress.yaml --- apiVersion: extensions/v1beta1 kind: Ingress metadata: name: prometheus namespace: istio-system spec: rules: - host: prometheus.istio.io http: paths: - path: / backend: serviceName: prometheus servicePort: 9090 --- apiVersion: extensions/v1beta1 kind: Ingress metadata: name: grafana namespace: istio-system spec: rules: - host: grafana.istio.io http: paths: - path: / backend: serviceName: grafana servicePort: 3000 --- apiVersion: extensions/v1beta1 kind: Ingress metadata: name: servicegraph namespace: istio-system spec: rules: - host: servicegraph.istio.io http: paths: - path: / backend: serviceName: servicegraph servicePort: 8088 --- apiVersion: extensions/v1beta1 kind: Ingress metadata: name: tracing namespace: istio-system spec: rules: - host: tracing.istio.io http: paths: - path: / backend: serviceName: tracing servicePort: 80
手工注入 Sidecar
手工或自动注入都会从 istio-system 命名空间的 istio-sidecar-injector 以及 istio ConfigMap 中获取配置信息
自动注入过程会在 Pod 的生成过程中进行注入，这种方法不会更改控制器的配置。手工删除 Pod 或者使用滚动更新都可以选择性的对 Sidecar 进行更新。
使用集群内置配置将 Sidecar 注入到 Deployment 中
[root@master1 ~]# istioctl kube-inject -f gateway-deployment.yaml | kubectl apply -f - deployment.apps/gateway created service/gateway created
查看注入到proxy

Sidecar 的自动注入
使用 Kubernetes 的 mutating webhook admission controller，可以进行 Sidecar 的自动注入。Kubernetes 1.9 以后的版本才具备这一能力。使用这一功能之前首先要检查 kube-apiserver 的进程，是否具备 admission-control 参数，并且这个参数的值中需要包含 MutatingAdmissionWebhook 以及 ValidatingAdmissionWebhook 两项，并且按照正确的顺序加载，这样才能启用 admissionregistration API：
kubectl api-versions | grep admissionregistration admissionregistration.k8s.io/v1alpha1 admissionregistration.k8s.io/v1beta1
跟手工注入不同的是，自动注入过程是发生在 Pod 级别的。因此是不会看到 Deployment 本身发生什么变化的。但是可以使用 kubectl describe 来观察单独的 Pod，在其中能看到注入 Sidecar 的相关信息。
[root@master1 helm]# kubectl get configmap istio-sidecar-injector -n istio-system -o yaml > istio-sidecar-injector.yaml [root@master1 helm]# vim istio-sidecar-injector.yaml 修改注入的proxy2 从docker.io
[root@master1 helm]# kubectl apply -f istio-sidecar-injector.yaml Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply configmap/istio-sidecar-injector configured
Webhook 的禁用或升级
缺省情况下，用于 Sidecar 注入的 Webhook 是启用的。如果想要禁用它，可以用 Helm ，将 sidecarInjectorWebhook.enabled 参数设为 false，生成一个 istio.yaml 进行更新。也就是：
helm template --namespace=istio-system --set sidecarInjectorWebhook.enabled=false install/kubernetes/helm/istio > istio.yaml kubectl create ns istio-system kubectl apply -n istio-system -f istio.yaml
应用部署
给 default 命名空间设置标签：istio-injection=enabled
kubectl label namespace default istio-injection=enabled
kubectl get namespace -L istio-injection NAME STATUS AGE ISTIO-INJECTION default Active 1h enabled istio-system Active 1h kube-public Active 1h kube-system Active 1h
这样就会在 Pod 创建时触发 Sidecar 的注入过程了。删掉运行的 Pod，会产生一个新的 Pod，新 Pod 会被注入 Sidecar。原有的 Pod 只有一个容器，而被注入 Sidecar 的 Pod 会有两个容器：
删除namespace 上的标签
kubectl label namespace default istio-injection-
kubectl delete pod sleep-776b7bcdcd-7hpnk kubectl get pod NAME READY STATUS RESTARTS AGE sleep-776b7bcdcd-7hpnk 1/1 Terminating 0 1m sleep-776b7bcdcd-bhn9m 2/2 Running 0 7s
查看被注入的 Pod 的细节。不难发现多出了一个 istio-proxy 容器及其对应的存储卷。注意用正确的 Pod 名称来执行下面的命令：
kubectl describe pod sleep-776b7bcdcd-bhn9m
禁用 default 命名空间的自动注入功能，然后检查新建 Pod 是不是就不带有 Sidecar 容器了
kubectl label namespace default istio-injection- kubectl delete pod sleep-776b7bcdcd-bhn9m kubectl get pod NAME READY STATUS RESTARTS AGE sleep-776b7bcdcd-bhn9m 2/2 Terminating 0 2m sleep-776b7bcdcd-gmvnr 1/1 Running 0 2s
理解原理
被 Kubernetes 调用时，admissionregistration.k8s.io/v1beta1#MutatingWebhookConfiguration 会进行配置。Istio 提供的缺省配置，会在带有 istio-injection=enabled 标签的命名空间中选择 Pod。使用 kubectl edit mutatingwebhookconfiguration istio-sidecar-injector 命令可以编辑目标命名空间的范围。
修改 mutatingwebhookconfiguration 之后，应该重新启动已经被注入 Sidecar 的 Pod。
istio-system 命名空间中的 ConfigMap istio-sidecar-injector 中包含了缺省的注入策略以及 Sidecar 的注入模板。
策略
disabled - Sidecar 注入器缺省不会向 Pod 进行注入。在 Pod 模板中加入 sidecar.istio.io/inject 注解并赋值为 true 才能启用注入。
enabled - Sidecar 注入器缺省会对 Pod 进行注入。在 Pod 模板中加入 sidecar.istio.io/inject 注解并赋值为 false 就会阻止对这一 Pod 的注入
下面的例子用 sidecar.istio.io/inject 注解来禁用 Sidecar 注入
apiVersion: extensions/v1beta1 kind: Deployment metadata: name: ignored spec: template: metadata: annotations: sidecar.istio.io/inject: "false" spec: containers: - name: ignored image: tutum/curl command: ["/bin/sleep","infinity"]
模板
Sidecar 注入模板使用的是 golang 模板，当解析和执行时，会解码为下面的结构，其中包含了将要注入到 Pod 中的容器和卷。
type SidecarInjectionSpec struct { InitContainers []v1.Container `yaml:"initContainers"` Containers []v1.Container `yaml:"containers"` Volumes []v1.Volume `yaml:"volumes"` ImagePullSecrets []corev1.LocalObjectReference `yaml:"imagePullSecrets"` }
在运行时，这个模板会形成如下的数据结构
type SidecarTemplateData struct { ObjectMeta *metav1.ObjectMeta Spec *v1.PodSpec ProxyConfig *meshconfig.ProxyConfig // 定义来自于 https://istio.io/docs/reference/config/service-mesh.html#proxyconfig MeshConfig *meshconfig.MeshConfig // 定义来自于 https://istio.io/docs/reference/config/service-mesh.html#meshconfig }
ObjectMeta 和 Spec 都来自于 Pod。ProxyConfig 和 MeshConfig 来自 istio-system 命名空间中的 istio ConfigMap。模板可以使用这些数据，有条件对将要注入的容器和卷进行定义。
例如下面的模板代码段来自于 install/kubernetes/istio-sidecar-injector-configmap-release.yaml
containers: - name: istio-proxy image: istio.io/proxy:0.5.0 args: - proxy - sidecar - --configPath - {{ .ProxyConfig.ConfigPath }} - --binaryPath - {{ .ProxyConfig.BinaryPath }} - --serviceCluster {{ if ne "" (index .ObjectMeta.Labels "app") -}} - {{ index .ObjectMeta.Labels "app" }} {{ else -}} - "istio-proxy" {{ end -}}
会在部署 Sleep 应用时应用到 Pod 上，并扩展为：
containers: - name: istio-proxy image: istio.io/proxy:0.5.0 args: - proxy - sidecar - --configPath - /etc/istio/proxy - --binaryPath - /usr/local/bin/envoy - --serviceCluster - sleep
kubectl delete mutatingwebhookconfiguration istio-sidecar-injector kubectl -n istio-system delete service istio-sidecar-injector kubectl -n istio-system delete deployment istio-sidecar-injector kubectl -n istio-system delete serviceaccount istio-sidecar-injector-service-account kubectl delete clusterrole istio-sidecar-injector-istio-system kubectl delete clusterrolebinding istio-sidecar-injector-admin-role-binding-istio-system
上面的命令不会从 Pod 中移除已经注入的 Sidecar。可以用一次滚动更新，或者简单的删除原有 Pod 迫使 Deployment 重新创建都可以移除 Sidecar。
除此以外，还可以删除我们在本任务中做出的其它更改：
kubectl label namespace default istio-injection-
Istio 对 Pod 和服务的要求
要成为服务网格的一部分，Kubernetes 集群中的 Pod 和服务必须满足以下几个要求：
-
需要给端口正确命名：服务端口必须进行命名。端口名称只允许是
<协议>[-<后缀>-]模式，其中<协议>部分可选择范围包括http、http2、grpc、mongo以及redis，Istio 可以通过对这些协议的支持来提供路由能力。例如name: http2-foo和name: http都是有效的端口名，但name: http2foo就是无效的。如果没有给端口进行命名，或者命名没有使用指定前缀，那么这一端口的流量就会被视为普通 TCP 流量（除非显式的用Protocol: UDP声明该端口是 UDP 端口）。 -
关联服务：Pod 必须关联到 Kubernetes 服务，如果一个 Pod 属于多个服务，这些服务不能再同一端口上使用不同协议，例如 HTTP 和 TCP。
-
Deployment 应带有
app标签：在使用 KubernetesDeployment进行 Pod 部署的时候，建议显式的为 Deployment 加上app标签。每个 Deployment 都应该有一个有意义的app标签。app标签在分布式跟踪的过程中会被用来加入上下文信息。
卸载
-
对于选项1，使用
kubectl进行卸载： -
$ kubectl delete -f istio.yaml
-
对于选项2，使用 Helm 进行卸载：
使用 Istio 的流量管理模型，本质上是将流量与基础设施扩容解耦，让运维人员可以通过 Pilot 指定流量遵循什么规则，而不是指定哪些 pod/VM 应该接收流量——Pilot 和智能 Envoy 代理会帮我们搞定。因此，例如，您可以通过 Pilot 指定特定服务的 5％ 流量可以转到金丝雀版本，而不必考虑金丝雀部署的大小，或根据请求的内容将流量发送到特定版本。
Pilot 和 Envoy
Istio 流量管理的核心组件是 Pilot，它管理和配置部署在特定 Istio 服务网格中的所有 Envoy 代理实例。它允许您指定在 Envoy 代理之间使用什么样的路由流量规则，并配置故障恢复功能，如超时、重试和熔断器。它还维护了网格中所有服务的规范模型，并使用这个模型通过发现服务让 Envoy 了解网格中的其他实例
每个 Envoy 实例都会维护负载均衡信息信息，这些信息来自 Pilot 以及对负载均衡池中其他实例的定期健康检查。从而允许其在目标实例之间智能分配流量，同时遵循其指定的路由规则。
Pilot 负责管理通过 Istio 服务网格发布的 Envoy 实例的生命周期
在网格中 Pilot 维护了一个服务规则表 并独立于底层平台。Pilot中的特定于平台的适配器负责适当地填充这个规范模型。例如，在 Pilot 中的 Kubernetes 适配器实现了必要的控制器，来观察 Kubernetes API 服务器，用于更改 pod 的注册信息、入口资源以及存储流量管理规则。这些数据被转换为规范。然后根据规范生成特定的 Envoy 的配置。
Pilot 公开了用于服务发现 、负载均衡池和路由表的动态更新的 API。
运维人员可以通过 Pilot 的 Rules API 指定高级流量管理规则。这些规则被翻译成低级配置，并通过 discovery API 分发到 Envoy 实例。
请求路由
Ingress 和 Egress
Istio 进入和离开服务网络的所有流量都会通过 Envoy 代理进行传输。通过将 Envoy 代理部署在服务之前，运维人员可以针对面向用户的服务进行 A/B 测试、部署金丝雀服务等。类似地，通过使用 Envoy 将流量路由到外部 Web 服务（例如，访问 Maps API 或视频服务 API）的方式，运维人员可以为这些服务添加超时控制、重试、断路器等功能，同时还能从服务连接中获取各种细节指标。
服务发现和负载均衡
Pilot 使用来自服务注册的信息，并提供与平台无关的服务发现接口。网格中的 Envoy 实例执行服务发现，并相应地动态更新其负载均衡池
网格中的服务使用其 DNS 名称访问彼此。服务的所有 HTTP 流量都会通过 Envoy 自动重新路由。Envoy 在负载均衡池中的实例之间分发流量。虽然 Envoy 支持多种复杂的负载均衡算法，但 Istio 目前仅允许三种负载均衡模式：轮循、随机和带权重的最少请求
除了负载均衡外，Envoy 还会定期检查池中每个实例的运行状况。Envoy 遵循熔断器风格模式，根据健康检查 API 调用的失败率将实例分类为不健康和健康两种。换句话说，当给定实例的健康检查失败次数超过预定阈值时，将会被从负载均衡池中弹出。类似地，当通过的健康检查数超过预定阈值时，该实例将被添加回负载均衡池。您可以在处理故障中了解更多有关 Envoy 的故障处理功能。
服务可以通过使用 HTTP 503 响应健康检查来主动减轻负担。在这种情况下，服务实例将立即从调用者的负载均衡池中删除。
故障处理
-
超时
-
具备超时预算，并能够在重试之间进行可变抖动（间隔）的有限重试功能
-
并发连接数和上游服务请求数限制
-
对负载均衡池中的每个成员主动（定期）运行健康检查
-
细粒度熔断器（被动健康检查）——适用于负载均衡池中的每个实例
在 Istio 中运行的应用程序是否仍需要处理故障？
是的。Istio可以提高网格中服务的可靠性和可用性。但是，应用程序仍然需要处理故障（错误）并采取适当的回退操作。例如，当负载均衡池中的所有实例都失败时，Envoy 将返回 HTTP 503。应用程序有责任实现必要的逻辑，对这种来自上游服务的 HTTP 503 错误做出合适的响应。
故障注入
虽然 Envoy sidecar/proxy 为在 Istio 上运行的服务提供了大量的故障恢复机制，但测试整个应用程序端到端的故障恢复能力依然是必须的。错误配置的故障恢复策略（例如，跨服务调用的不兼容/限制性超时）可能导致应用程序中的关键服务持续不可用，从而破坏用户体验。
Istio 能在不杀死 Pod 的情况下，将特定协议的故障注入到网络中，在 TCP 层制造数据包的延迟或损坏。我们的理由是，无论网络级别的故障如何，应用层观察到的故障都是一样的，并且可以在应用层注入更有意义的故障（例如，HTTP 错误代码），以检验和改善应用的弹性。
运维人员可以为符合特定条件的请求配置故障，还可以进一步限制遭受故障的请求的百分比。可以注入两种类型的故障：延迟和中断。延迟是计时故障，模拟网络延迟上升或上游服务超载的情况。中断是模拟上游服务的崩溃故障。中断通常以 HTTP 错误代码或 TCP 连接失败的形式表现。
规则配置
Istio 提供了一个简单的配置模型，用来控制 API 调用以及应用部署内多个服务之间的四层通信。运维人员可以使用这个模型来配置服务级别的属性，这些属性可以是断路器、超时、重试，以及一些普通的持续发布任务，例如金丝雀发布、A/B 测试、使用百分比对流量进行控制，从而完成应用的逐步发布等。
Istio 中包含有四种流量管理配置资源，分别是 VirtualService（虚拟服务）、DestinationRule(重点规则)、ServiceEntry（服务入口） 以及 Gateway（网关）。下面会讲一下这几个资源的一些重点。在网络参考中可以获得更多这方面的信息。
-
VirtualService在 Istio 服务网格中定义路由规则，控制路由如何路由到服务上。 -
DestinationRule是VirtualService路由生效后，配置应用与请求的策略集 -
ServiceEntry是通常用于在 Istio 服务网格之外启用对服务的请求。 -
Gateway为 HTTP/TCP 流量配置负载均衡器，最常见的是在网格的边缘的操作，以启用应用程序的入口流量。
例如，将 reviews 服务 100％ 的传入流量发送到 v1 版本，这一需求可以用下面的规则来实现：
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: reviews spec: hosts: - reviews http: - route: - destination: host: reviews subset: v1
这个配置的用意是，发送到 reviews 服务（在 host 字段中标识）的流量应该被路由到 reviews 服务实例的 v1 子集中。路由中的 subset 制定了一个预定义的子集名称，子集的定义来自于目标规则配置：
子集指定了一个或多个特定版本的实例标签。例如，在 Kubernetes 中部署 Istio 时，”version: v1” 表示只有包含 “version: v1” 标签版本的 pods 才会接收流量。
在 DestinationRule 中，你可以添加其他策略，例如：下面的定义指定使用随机负载均衡模式：
apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: name: reviews spec: host: reviews trafficPolicy: loadBalancer: simple: RANDOM subsets: - name: v1 labels: version: v1 - name: v2 labels: version: v2
可以使用 kubectl 命令配置规则。在配置请求路由任务中包含有配置示例。
Virtual Service
路由规则对应着一或多个用 VirtualService 配置指定的请求目的主机。这些主机可以是也可以不是实际的目标负载，甚至可以不是同一网格内可路由的服务。例如要给到 reviews 服务的请求定义路由规则，可以使用内部的名称 reviews，也可以用域名 bookinfo.com，VirtualService可以定义这样的 host 字段：
在服务之间分拆流量
每个路由规则都需要对一或多个有权重的后端进行甄别并调用合适的后端。每个后端都对应一个特定版本的目标服务，服务的版本是依靠标签来区分的。如果一个服务版本包含多个注册实例，那么会根据为该服务定义的负载均衡策略进行路由，缺省策略是 round-robin
例如下面的规则会把 25% 的 reviews 服务流量分配给 v2 标签；其余的 75% 流量分配给 v1：
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: reviews spec: hosts: - reviews http: - route: - destination: host: reviews subset: v1 weight: 75 - destination: host: reviews subset: v2 weight: 25
超时和重试
缺省情况下，HTTP 请求的超时设置为 15 秒，可以使用路由规则来覆盖这个限制
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: ratings spec: hosts: - ratings http: - route: - destination: host: ratings subset: v1 timeout: 10s
还可以用路由规则来指定某些 http 请求的重试次数。下面的代码可以用来设置最大重试次数，或者在规定时间内一直重试，时间长度同样可以进行覆盖
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: ratings spec: hosts: - ratings http: - route: - destination: host: ratings subset: v1 retries: attempts: 3 perTryTimeout: 2s
错误注入
在根据路由规则向选中目标转发 http 请求的时候，可以向其中注入一或多个错误。错误可以是延迟，也可以是退出。
下面的例子在目标为 ratings:v1 服务的流量中，对其中的 10% 注入 5 秒钟的延迟。
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: ratings spec: hosts: - ratings http: - fault: #过错 delay: #延迟 percent: 10 fixedDelay: 5s route: - destination: host: ratings subset: v1
可以使用其他类型的故障，终止、提前终止请求。例如，模拟失败。
接下来，在目标为 ratings:v1 服务的流量中，对其中的 10% 注入 HTTP 400 错误。
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: ratings spec: hosts: - ratings http: - fault: abort: #终止 percent: 10 httpStatus: 400 route: - destination: host: ratings subset: v1
有时会把延迟和退出同时使用。例如下面的规则对从 reviews:v2 到 ratings:v1 的流量生效，会让所有的请求延迟 5 秒钟，接下来把其中的 10% 退出：
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: ratings spec: hosts: - ratings http: - match: - sourceLabels: app: reviews version: v2 fault: delay: fixedDelay: 5s abort: percent: 10 httpStatus: 400 route: - destination: host: ratings subset: v1
条件规则
可以选择让规则只对符合某些要求的请求生效：
1. 使用工作负载 label 限制特定客户端工作负载。例如，规则可以指示它仅适用于实现 reviews 服务的工作负载实例（pod）的调用
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: ratings spec: hosts: - ratings http: - match: sourceLabels: app: reviews ...
sourceLabels 的值取决于服务的实现。例如，在 Kubernetes 中，它可能与相应 Kubernetes 服务的 pod 选择器中使用的 label 相同。
以上示例还可以进一步细化为仅适用于 reviews 服务版本 v2 负载均衡实例的调用：
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: ratings spec: hosts: - ratings http: - match: - sourceLabels: app: reviews version: v2 ...
2. 根据 HTTP Header 选择规则。下面的规则只会对包含了 end-user 标头的来源请求，且值为 jason 的请求生效
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: reviews spec: hosts: - reviews http: - match: - headers: end-user: exact: jason
如果规则中指定了多个标头，则所有相应的标头必须匹配才能应用规则。
3. 根据请求URI选择规则。例如，如果 URI 路径以 /api/v1 开头，则以下规则仅适用于请求：
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: productpage spec: hosts: - productpage http: - match: - uri: prefix: /api/v1 ...
多重匹配条件
可以同时设置多个匹配条件。在这种情况下，根据嵌套，应用 AND 或 OR 语义。
如果多个条件嵌套在单个匹配子句中，则条件为 AND。例如，以下规则仅适用于客户端工作负载为 reviews:v2 且请求中包含 jason 的自定义 end-user 标头：
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: ratings spec: hosts: - ratings http: - match: - sourceLabels: app: reviews version: v2 headers: end-user: exact: jason ...
相反，如果条件出现在单独的匹配子句中，则只应用其中一个条件（OR 语义）：
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: ratings spec: hosts: - ratings http: - match: - sourceLabels: app: reviews version: v2 - headers: end-user: exact: jason
如果客户端工作负载是 reviews:v2，或者请求中包含 jason 的自定义 end-user 标头，则适用此规则。
优先级
当对同一目标有多个规则时，会按照在 VirtualService 中的顺序进行应用，换句话说，列表中的第一条规则具有最高优先级。
为什么优先级很重要：当对某个服务的路由是完全基于权重的时候，就可以在单一规则中完成。另一方面，如果有多重条件（例如来自特定用户的请求）用来进行路由，就会需要不止一条规则。这样就出现了优先级问题，需要通过优先级来保证根据正确的顺序来执行规则。
常见的路由模式是提供一或多个高优先级规则，这些优先规则使用源服务以及 Header 来进行路由判断，然后才提供一条单独的基于权重的规则，这些低优先级规则不设置匹配规则，仅根据权重对所有剩余流量进行分流。
例如下面的 VirtualService 包含了两个规则，所有对 reviews 服务发起的请求，如果 Header 包含 Foo=bar，就会被路由到 v2 实例，而其他请求则会发送给 v1 ：
apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: reviews spec: hosts: - reviews http: - match: - headers: Foo: exact: bar route: - destination: host: reviews subset: v2 - route: - destination: host: reviews subset: v1
基于 Header 的规则具有更高优先级。如果降低它的优先级，那么这一规则就无法生效了，这是因为那些没有限制的权重规则会首先被执行，也就是说所有请求即使包含了符合条件的 Foo 头，也都会被路由到 v1。流量特征被判断为符合一条规则的条件的时候，就会结束规则的选择过程，这就是在存在多条规则时，需要慎重考虑优先级问题的原因。
目标规则
在请求被 VirtualService 路由之后，DestinationRule 配置的一系列策略就生效了。这些策略由服务属主编写，包含断路器、负载均衡以及 TLS 等的配置内容。
DestinationRule 还定义了对应目标主机的可路由 subset（例如有命名的版本）。VirtualService 在向特定服务版本发送请求时会用到这些子集。
下面是 reviews 服务的 DestinationRule 配置策略以及子集：
apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
name: reviews
spec:
host: reviews
trafficPolicy:
loadBalancer:
simple: RANDOM
subsets:
- name: v1
labels:
version: v1
- name: v2
labels:
version: v2
trafficPolicy:
loadBalancer:
simple: ROUND_ROBIN
- name: v3
labels:
version: v3
在单个 DestinationRule 配置中可以包含多条策略（比如 default 和 v2）
断路器
可以用一系列的标准，例如连接数和请求数限制来定义简单的断路器。
例如下面的 DestinationRule 给 reviews 服务的 v1 版本设置了 100 连接的限制：
apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: name: reviews spec: host: reviews subsets: - name: v1 labels: version: v1 trafficPolicy: connectionPool: tcp: maxConnections: 100
规则评估
和路由规则类似，DestinationRule 中定义的策略也是和特定的 host 相关联的，如果指定了 subset，那么具体生效的 subset 的决策是由路由规则来决定的。
规则评估的第一步，是确认 VirtualService 中所请求的主机相对应的路由规则（如果有的话），这一步骤决定了将请求发往目标服务的哪一个 subset（就是特定版本）。下一步，被选中的 subset 如果定义了策略，就会开始是否生效的评估。
注意：这一算法需要留心是，为特定 subset 定义的策略，只有在该 subset 被显式的路由时候才能生效。例如下面的配置，只为 review 服务定义了规则（没有对应的 VirtualService 路由规则）。
