②. 编写Dockerfile文件
- ①. 需要注意的是,这里的8080端口,如果在application.yaml中不写端口默认是8080
FROM openjdk:8u282-slim # 如下操作可以让容器时间和虚拟机时间一致 RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo 'Asia/Shanghai' >/etc/timezone LABEL maintainer="845195485@qq.com" # COPY --from=buildapp /app/app.jar /app.jar COPY demo-0.0.1-SNAPSHOT.jar /app.jar EXPOSE 8080 # CMD ["--server.prot=8080"] ENV JAVA_OPTS="" ENV PARAMS="" ENTRYPOINT [ "sh", "-c", "java -Djava.security.egd=file:/dev/./urandom $JAVA_OPTS -jar /app.jar $PARAMS" ]
③. 将jar包和Dockerfile文件上传服务器
- ①. 在服务器上进行如下操作
[root@k8s-master dockerFileTest]# ls demo demo-0.0.1-SNAPSHOT.jar Dockerfile [root@k8s-master dockerFileTest]# docker build -t dockerfiledemo:1.0 -f Dockerfile .

②. 通过浏览器访问(http://139.198.169.136:49170/helloTang)
