1.创建springboot项目 打包 并运行验证服务
2.制作Dockerfile文件
FROM java:8 COPY *.jar /app.jar CMD ["--server.port=8080"] EXPOSE 8080 ENTRYPOINT ["java","-jar","/app.jar"]
3.通过Dockerfile文件生成镜像
将 jar包以及Dockerfile文件上传到服务器。
[root@VM-0-13-centos idea]# docker build -t xkjindemo .
4.由镜像生成容器并验证结果
[root@VM-0-13-centos idea]# docker images
