1：首先构建一个SpringBoot项目只需要添加web依赖
2：编写一个controller用于测试
3：本机启动观察是否能够成功访问
4:打包
5：找到生成的jar包位置
6：jar包的启动运行测试
7:编写Dockerfile文件
8：把我们的jar包和Dockerfile文件上传服务器
9：利用上传的文件构建镜像[root@iZwz9hv1phm24s3jicy8x1Z idea]# lsDockerfile Docker-Package-0.0.1-SNAPSHOT.jar[root@iZwz9hv1phm24s3jicy8x1Z idea]# docker build -t dongmu-springboot-project .Sending build context to Docker daemon 17.54MBStep 1/5 : FROM java:88: Pulling from library/java5040bd298390: Pull complete fce5728aad85: Pull complete 76610ec20bf5: Pull complete 60170fec2151: Pull complete e98f73de8f0d: Pull complete 11f7af24ed9c: Pull complete 49e2d6393f32: Pull complete bb9cdec9c7f3: Pull complete Digest: sha256:c1ff613e8ba25833d2e1940da0940c3824f03f802c449f3d1815a66b7f8c0e9dStatus: Downloaded newer image for java:8 ---> d23bdf5b1b1bStep 2/5 : COPY /*.jar /app.jar ---> a16d648390dfStep 3/5 : CMD ["--server.port=8080"] ---> Running in bc45f72484c7Removing intermediate container bc45f72484c7 ---> 713861b331adStep 4/5 : EXPOSE 8080 ---> Running in 7a28e4939b5eRemoving intermediate container 7a28e4939b5e ---> 08f540832166Step 5/5 : ENTRYPOINT ["java","-jar","/app.jar"] ---> Running in 6cd669cd522cRemoving intermediate container 6cd669cd522c ---> 1fd9f50df534Successfully built 1fd9f50df534Successfully tagged dongmu-springboot-project:latest
