如何编写正确的 yaml 以在 Azure devops 中部署 kubernetes 集群？

Question

我正在尝试使用 kubernetes 在 Azure 云中建立 Dockerized Angular 应用程序，但我不能这样做。一切看起来都很好，但是当我进入时我看不到角度应用程序 浏览器上的网址。我的 Dockerfile 或 yml 文件有什么问题？你能给我一些建议吗？我在 2 天内进行了大量搜索，但没有找到解决方案。

deployment.yml：

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: xxx-pod
  name: xxx-deployment
spec:
  replicas: 5
  selector:
    matchLabels:
      app: xxx-pod
  strategy: {}
  template:
    metadata:
     labels:
        app: xxx-pod
    spec:
      containers:
      - image: xxx.azurecr.io/cm-webui:v1
        name: webapp
        imagePullPolicy: Always
        resources: {}
        ports:
          - containerPort: 3080 
status: {}

service.yml:

apiVersion: v1
kind: Service
metadata:
  name: xxx-service
  labels:
    run: xxx-pod
spec:
  selector:
    app: xxx-pod
  ports:
  - port: 3080
    targetPort: 80
  type: LoadBalancer

Dockerfile：

FROM node:10 AS ui-build
WORKDIR /usr/src/app
COPY my-app/ ./my-app/
RUN cd my-app && npm install @angular/cli && npm install && npm run build

FROM node:10 AS server-build
WORKDIR /root/
COPY --from=ui-build /usr/src/app/my-app/dist ./my-app/dist
COPY package*.json ./
RUN npm install
COPY server.js .

EXPOSE 3080

CMD ["node", "server.js"]

Answer 1

在服务定义中，您交换了 port 和 targetPort 值。 port 应该是 80 和 targetPort 3080。
