部署可观测平台

部署拉取Istio官方仓库

git clone https://github.com/istio/istio.git

 kubectl apply -f samples/addons

通过 Gateway 访问 Kiali

ingress_gateway.kiali_gateway.yaml

apiVersion: networking.istio.io/v1alpha3  
kind: Gateway  
metadata:  
  name: bookinfo-kiali-gateway  
spec:  
  selector:  
    istio: ingress
  servers:  
  - port:  
      number: 8015029  
      name: httphttp-kiali  
      protocol: HTTP  
    hosts:  
    - "*"  

kubectl -n bookinfoistio-system apply -f ingress_gateway.kiali_gateway.yaml  

部署创建一个 VirtualService 资源，将 Gateway 路由到 Kiali 服务.

productpage_vs.kiali_vs.yaml

apiVersion: networking.istio.io/v1alpha3  
kind: VirtualService  
metadata:  
  name: bookinfokiali  
spec:  
  hosts:  
  - "*"  
  gateways:  
  - bookinfo-kiali-gateway  
  http:  
  - match:  
    - uri:  
        exact: /productpage
    - uri:
        prefix: /static
    - uri:
        exact: /login
    - uri:
        exact: /logout
    - uri:
        prefix: /api/v1/productskiali  
    route:  
    - destination:  
        host: productpagekiali.istio-system.svc.cluster.local  
        port:  
          number: 908020001

kubectl -n bookinfoistio-system apply -f productpage_vs.kiali_vs.yaml

通过istio访问 带上/productpage

#查看istio-ingress的NodePort端口
kubectl get svc -n然后修改 istio-systemingressgateway，新增加一个配置为 

kiali

可手动修改访问端口，port端口号和ingress_gateway.yaml文件中number对上即可暴露服务。

kubectl edit svc istio-ingressgatewayingress -n istio-system

  - name: http-testkiali
    nodePort: 3266632667
    port: 66615029
    protocol: TCP
    targetPort: 66615029

测试查看链路追踪数据

for i in `seq 1 1000`; do curl -s -o /dev/null http://10.1.1.102:32666/productpage; done

然后访问：http://10.1.1.102:32667/kiali

修复 Kiali Grafana 问题 添加grafana配置url

 kubectl edit configmap kiali -n istio-system
 
     external_services:
      grafana:
        enabled: true
        url: "http://grafana.istio-system.svc.cluster.local:3000"
        in_cluster_url: "http://grafana.istio-system.svc.cluster.local:3000"

重启kiali

kubectl delete -n istio-system pod kiali-6bd54bd76-nvjbp
