    本文主要演示一下如何在mac m2安装istio，及基于header的流量路由。

    安装istio

    下载https://github.com/istio/istio/releases/download/1.18.2/istio-1.18.2-osx-arm64.tar.gz
    解压，并将istio-1.18.2/bin添加到PATH中

    istioctl install --set profile=demo -y
✔ Istio core installed
✔ Istiod installed
✔ Egress gateways installed
✔ Ingress gateways installed
✔ Installation complete                                                                               Making this installation the default for injection and validation.

kubectl get ns
NAME                 STATUS   AGE
default              Active   75m
istio-system         Active   104s
kube-node-lease      Active   75m
kube-public          Active   75m
kube-system          Active   75m
local-path-storage   Active   75m
➜  ~ kubectl get pods -n istio-system
NAME                                    READY   STATUS    RESTARTS   AGE
istio-egressgateway-75db994b58-jdztx    1/1     Running   0          61s
istio-ingressgateway-79bb75ddbb-965t8   1/1     Running   0          61s
istiod-68cb9f5cb6-jksg5                 1/1     Running   0          115s

    给default命名空间注入istio

    kubectl label namespace default istio-injection=enabled
namespace/default labeled

    部署bookinfo示例

    kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml
service/details created
serviceaccount/bookinfo-details created
deployment.apps/details-v1 created
service/ratings created
serviceaccount/bookinfo-ratings created
deployment.apps/ratings-v1 created
service/reviews created
serviceaccount/bookinfo-reviews created
deployment.apps/reviews-v1 created
deployment.apps/reviews-v2 created
deployment.apps/reviews-v3 created
service/productpage created
serviceaccount/bookinfo-productpage created
deployment.apps/productpage-v1 created

kubectl get services

kubectl get pods

reviews-v3-797fc48bc9-xzzq8       2/2     Running   0          59m

    访问应用

    kubectl exec "$(kubectl get pod -l app=ratings -o jsonpath='{.items[0].metadata.name}')" -c ratings -- curl -sS productpage:9080/productpage | grep -o "<title>.*</title>"

    开启网关

    kubectl apply -f samples/bookinfo/networking/bookinfo-gateway.yaml

gateway.networking.istio.io/bookinfo-gateway created
virtualservice.networking.istio.io/bookinfo created

    验证配置

    istioctl analyze

✔ No validation issues found when analyzing namespace: default.

    确定入站 IP 和端口

    kubectl get service -n istio-system
NAME                   TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)                                                                      AGE
istio-egressgateway    ClusterIP      10.96.85.74     <none>        80/TCP,443/TCP                                                               91m
istio-ingressgateway   LoadBalancer   10.96.159.108   <pending>     15021:32027/TCP,80:32707/TCP,443:30486/TCP,31400:32398/TCP,15443:32482/TCP   91m
istiod                 ClusterIP      10.96.8.225     <none>        15010/TCP,15012/TCP,443/TCP,15014/TCP                                        92m
    这里没有external-ip，通过cluster-ip访问
    kubectl exec "$(kubectl get pod -l app=ratings -o jsonpath='{.items[0].metadata.name}')" -c ratings -- curl -sS 10.96.159.108/productpage | grep "Reviews served by" -A2
        <dt>Reviews served by:</dt>
        <u>reviews-v2-955b74755-twbrw</u>
    多访问几次，会发现有时候是路由到reviews的V1版本，有时候是V2版本，有时候是V3版本

    流量路由示例

    创建默认DestinationRule

    kubectl apply -f samples/bookinfo/networking/destination-rule-all.yaml

    将Istio配置为路由到Bookinfo微服务的v1版本，reviews服务的版本1
    kubectl exec "$(kubectl get pod -l app=ratings -o jsonpath='{.items[0].metadata.name}')" -c ratings -- curl -sS 10.96.159.108/productpage | grep "Reviews served by" -A2
        <dt>Reviews served by:</dt>
        <u>reviews-v1-5cf854487-86f8d</u>
    多执行几次发现都是路由到reviews的v1版本

    指定路由到reviews的v2版本

    kubectl apply -f samples/bookinfo/networking/virtual-service-reviews-test-v2.yaml

    可以看到http2的nodePort为32707

    可以看到nodeip为192.168.228.2

    于是访问http://192.168.228.2:32707/productpage，没有评分，如果以用户jason(密码jason)登录，发现有评分，Reviews served by为reviews-v2-955b74755-twbrw，路由到了v2版本

    不经过gateway，直接通过productpage的clusterip访问

    kubectl get svc productpage
NAME          TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)    AGE
productpage   ClusterIP   10.96.214.31   <none>        9080/TCP   31m

kubectl exec "$(kubectl get pod -l app=ratings -o jsonpath='{.items[0].metadata.name}')" -c ratings -- curl -H "Cookie:session=eyJ1c2VyIjoiamFzb24ifQ.ZMJ29Q.QzbItYVJISKKnrbii9ii0fJTU38" -sS 10.96.214.31:9080/productpage | grep "Reviews served by" -A2
        <dt>Reviews served by:</dt>
        <u>reviews-v2-955b74755-twbrw</u>
    发现也能够正确路由到reviews的v2版本

    移除jason的cookie

    kubectl exec "$(kubectl get pod -l app=ratings -o jsonpath='{.items[0].metadata.name}')" -c ratings -- curl -sS 10.96.214.31:9080/productpage | grep "Reviews served by" -A2
        <dt>Reviews served by:</dt>
        <u>reviews-v1-5cf854487-86f8d</u>
    发现路由到了reviews的v1版本

    小结

    istio于2023年7月12日正式从CNCF正式毕业了，是时候在生产上把istio用起来了，istio的sidecar路由相比于基于特定语言sdk做路由更为省事。
