kubeadm istio 搭建k8s微服务(2)

为什么80%的码农都做不了架构师？>>>   

安装istio

下载istio

curl -L https://git.io/getLatestIstio | sh -
cd istio-1.0.5/

使用helm安装istio 配置改成NodePort

helm template install/kubernetes/helm/istio \
--name istio \
--namespace istio-system \
--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 \
> istio.yaml

kubectl create namespace istio-system
kubectl create -f istio.yaml

监控istio部署情况

kubectl get pods -n istio-system

---

测试istio路由

安装httpbin

kubectl apply -f samples/httpbin/httpbin.yaml

查看istio ingressgateway端口

kubectl get svc istio-ingressgateway -n istio-system
// 80:31380/TCP,443:31390/TCP

查看istio ingressgateway部署机器ip

export INGRESS_HOST=$(kubectl get po -l istio=ingressgateway -n istio-system -o 'jsonpath={.items[0].status.hostIP}')
echo $INGRESS_HOST

配置外部nginx反向代理到ip和端口(省略)

配置istio路由

cat <

访问 http://xxxxx/headers 打印出请求header结果

清理测试数据

kubectl delete gateway httpbin-gateway
kubectl delete virtualservice httpbin
kubectl delete --ignore-not-found=true -f samples/httpbin/httpbin.yaml
