Istio没有将流量路由到特定的Pod

标签: istio

我在k8s上设置了一堆容器。每个吊舱运行一个容器。有一个反向代理容器,它在运行时容器中调用服务。我已经设置了两个运行时Pod v1和v2。我的目标是使用istio将所有流量从反向代理Pod路由到运行时Pod v1。

我已经配置了istio,下面的屏幕快照将使您对环境有所了解。 [![在此处输入图片描述] [1]] [1]

我的k8s yaml看起来像这样:

流从Postman工具->入口ip地址->运行反向代理的容器->运行时容器 我的目标是确保只有运行时v1容器上的容器才能获得流量。但是,流量会同时路由到v1和v2。

我的错是什么?有人可以帮我吗?

我尝试了以下操作,但没有成功。流量被路由到v1和v2。

apiVersion: networking.istio.io/v1alpha3

我尝试将虚拟服务更改为:

      weight: 100
    - destination:
        host: isamruntime
        subset: v2
        port:
           number: 443
      weight: 0

然后按如下所示使用卷曲

curl命令返回预期的反向代理的登录页面。我的运行时服务在反向代理后面。反向代理将调用运行时服务。我在文档中的某处看到可以使用-mesh。那也无济于事。

我运行了另一个curl命令,该命令实际上触发了对反向代理的调用,并且反向代理调用了运行时。

预计会出现错误,因为这是仅允许HTTP POST的终点。 [1]:https://i.stack.imgur.com/dOMnD.png

流量同时路由到v1和v2

这很可能意味着Istio没有处理流量,而K8s Service正在做简单的循环。

我认为您在Debugging Istio: How to Fix a Broken Service Mesh (Cloud Next '19)会议中看到了确切的情况。

这对于了解istioctl的功能和调试意外行为是非常有用的会话,但是长话短说,您需要调整服务定义。

---
apiVersion: v1
kind: Service
metadata:
  name: isamruntime
spec:
  ports:
    - port: 443
      name: http-isamruntime # Add prefix of http
      protocol: TCP
  selector:
    app: isamruntime

参考:https://istio.io/latest/docs/reference/config/networking/virtual-service/#VirtualService

注意:上面的http-前缀假定您在打服务之前要终止TLS。根据您的用例,您可能还需要调整VirtualService。

答案 1 :(得分:1)

我的流程正常了。我不需要网关,因为我的流量来自反向代理->运行时。反向代理和运行时位于k8s cluser内部,是东西向流量。我的服务需要tcp-,而我的虚拟服务需要tcp映射。 yaml文件在下面给出。我感谢大家为我指引正确的方向。 我的服务Yaml:

---
apiVersion: v1
kind: Service
metadata:
  name: isamruntime
spec:
  ports:
    - port: 443
      name: tcp-isamruntime # Add prefix of tcp to match traffic type
      protocol: TCP
  selector:
    app: isamruntime

我的虚拟服务和目标规则Yaml:

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: isamruntime
spec:
  hosts:
    - isamruntime
  tcp:
    - match:
      - port: 443
      route:
      - destination:
          host: isamruntime.default.svc.cluster.local
          port:
            number: 443
          subset: v1
        weight: 0
      - destination:
          host: isamruntime.default.svc.cluster.local
          port:
            number: 443
          subset: v2
        weight: 100

感谢您查看问题。我尝试使用此方法提出您的建议:

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: isamruntime
spec:
  hosts:
    - isamruntime
  gateways:
    - isamruntime-gateway
  http:
  - route:
    - destination:
        host: isamruntime
        subset: v1
        port:
           number: 443
      weight: 100
    - destination:
        host: isamruntime
        subset: v2
        port:
           number: 443
      weight: 0
---
apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: isamruntime-v1
spec:
  host: isamruntime
  subsets:
  - name: v1
    labels:
      version: v1
#  - name: v2
#    labels:
#      version: v2
---
apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: isamruntime-v2
spec:
  host: isamruntime
  subsets:
  - name: v2
    labels:
      version: v2
#  - name: v2
#    labels:
#      version: v2

但是,它没有用。

与主机名有关。它是否必须具有-isamruntime.default.svc.cluster.local之类的名称空间,还是我的容器应在非默认名称空间中运行?
