完整教程：阿里云k8s部署微服务yaml和Dockerfile文件脚本

1. Dockerfile 文件

   #基础镜像，如果本地仓库没有，会从远程仓库拉取 openjdk:8
   FROM registry.cn-hangzhou.aliyuncs.com/dockerhub_mirror/java:21-anolis
   #暴露端口
   EXPOSE 8080
   #容器中创建目录
   RUN mkdir -p /usr/local/cenobitor
   #编译后的jar包copy到容器中创建到目录内12
   COPY target/codeup-demo-0.0.1.jar /usr/local/cenobitor/codeup-demo-0.0.1.jar
   #指定容器时区
   RUN rm -f /etc/localtime \
   && ln -sv /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
   && echo "Asia/Shanghai" > /etc/timezone
   #指定容器启动时要执行的命令
   ENTRYPOINT ["java","-Dserver.port=8080","-jar","/usr/local/cenobitor/codeup-demo-0.0.1.jar"]

2. k8s yaml文件

3. apiVersion: v1
   kind: Service
   metadata:

         protocol: TCP
         targetPort: 8080
         #nodePort: 31080 #service对外开放端口
     selector:
       app: codeup-demo

   spec:
     replicas: 1 #运行容器的副本数，修改这里可以快速修改分布式节点数量
     progressDeadlineSeconds: 600 #在Deployment 在进度卡住6分钟后报告
     minReadySeconds: 10 #Pod被认为是可用状态的最小秒数。默认是0
     strategy:
       rollingUpdate:
         maxSurge: 1 #升级过程中激增Pod的最大数量
         maxUnavailable: 0 #升级过程中不可用Pod的最大数量

             imagePullPolicy: Always #pull镜像时机，
             ports:
               - containerPort: 8080 #容器对外开放端口,需与springboot配置文件一致
             env:
