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

以上就是springboot打包docker镜像发布的方法的详细内容。
