部署bookinfo测试案例

部署bookinfo测试

kubectl create namespace bookinfo
kubectl label namespace bookinfo istio-injection=enabled

使用 Deployment 部署 details 应用。details_deploy.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: details-v1
  labels:
    app: details
    version: v1
spec:
  replicas: 1
  selector:
    matchLabels:
      app: details
      version: v1
  template:
    metadata:
      labels:
        app: details
        version: v1
    spec:
      serviceAccountName: bookinfo-details
      containers:
      - name: details
        image: docker.m.daocloud.io/istio/examples-bookinfo-details-v1:1.17.0
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 9080
        securityContext:
          runAsUser: 1000

kubectl -n bookinfo apply -f details_deploy.yaml

为 details 服务配置 Kubernetes Service 。details_svc.yaml

apiVersion: v1
kind: Service
metadata:
  name: details
  labels:
    app: details
    service: details
spec:
  ports:
  - port: 9080
    name: http
  selector:
    app: details

kubectl -n bookinfo apply -f details_svc.yaml

接下来为 details 服务创建一个 ServiceAccount。details_sa.yaml

apiVersion: v1

metadata:
  name: bookinfo-details
  labels:
    account: details

kubectl -n bookinfo apply -f details_sa.yaml

apiVersion: v1
kind: Service
metadata:
  name: reviews
  labels:
    app: reviews
    service: reviews
spec:
  ports:
  - port: 9080
    name: http
  selector:
    app: reviews

reviews_sa.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: bookinfo-reviews
  labels:
    account: reviews

部署命令

kubectl -n bookinfo apply -f reviews_v1_deploy.yaml
kubectl -n bookinfo apply -f reviews_v2_deploy.yaml
kubectl -n bookinfo apply -f reviews_v3_deploy.yaml
kubectl -n bookinfo apply -f reviews_svc.yaml
kubectl -n bookinfo apply -f reviews_sa.yaml

  replicas: 1
  selector:
    matchLabels:
      app: productpage
      version: v1
  template:
    metadata:
      labels:
        app: productpage
        version: v1
    spec:
      serviceAccountName: bookinfo-productpage
      containers:
      - name: productpage
        image: docker.m.daocloud.io/istio/examples-bookinfo-productpage-v1:1.17.0
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 9080
        volumeMounts:
        - name: tmp
          mountPath: /tmp
        securityContext:

      volumes:
      - name: tmp
        emptyDir: {}

productpage_svc.yaml

apiVersion: v1
kind: Service
metadata:
  name: productpage
  labels:
    app: productpage
    service: productpage
spec:
  ports:
  - port: 9080
    name: http
  selector:
    app: productpage

productpage_sa.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: bookinfo-productpage
  labels:
    account: productpage

部署命令

kubectl -n bookinfo apply -f productpage_deploy.yaml
kubectl -n bookinfo apply -f productpage_svc.yaml
kubectl -n bookinfo apply -f productpage_sa.yaml

检查

执行命令完成后，查看 bookinfo 命名空间下的 pod、svc、sa。

kubectl get pods -n bookinfo
kubectl -n bookinfo get svc
kubectl -n bookinfo get sa
部署 Gateway

ingress_gateway.yaml

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: bookinfo-gateway
spec:
  selector:
    istio: ingress
  servers:
  - port:
      number: 80
      name: http
      protocol: HTTP
    hosts:
    - "*"

kubectl -n bookinfo apply -f ingress_gateway.yaml
部署 VirtualService

productpage_vs.yaml

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: bookinfo
spec:
  hosts:
  - "*"
  gateways:
  - bookinfo-gateway
  http:
  - match:
    - uri:
        exact: /productpage
    - uri:
        prefix: /static
    - uri:
        exact: /login
    - uri:
        exact: /logout
    - uri:
        prefix: /api/v1/products
    route:
    - destination:
        host: productpage
        port:
          number: 9080

kubectl -n bookinfo apply -f productpage_vs.yaml
通过istio访问 带上/productpage
#查看istio-ingress的NodePort端口
kubectl get svc -n istio-system
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
kubectl edit svc istio-ingressgateway -n istio-system
  - name: http-test
    nodePort: 32666
    port: 666
    protocol: TCP
    targetPort: 666
