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]# ls Dockerfile Docker-Package-0.0.1-SNAPSHOT.jar [root@iZwz9hv1phm24s3jicy8x1Z idea]# docker build -t dongmu-springboot-project . Sending build context to Docker daemon 17.54MB Step 1/5 : FROM java:8 8: Pulling from library/java 5040bd298390: 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:c1ff613e8ba25833d2e1940da0940c3824f03f802c449f3d1815a66b7f8c0e9d Status: Downloaded newer image for java:8 ---> d23bdf5b1b1b Step 2/5 : COPY /*.jar /app.jar ---> a16d648390df Step 3/5 : CMD ["--server.port=8080"] ---> Running in bc45f72484c7 Removing intermediate container bc45f72484c7 ---> 713861b331ad Step 4/5 : EXPOSE 8080 ---> Running in 7a28e4939b5e Removing intermediate container 7a28e4939b5e ---> 08f540832166 Step 5/5 : ENTRYPOINT ["java","-jar","/app.jar"] ---> Running in 6cd669cd522c Removing intermediate container 6cd669cd522c ---> 1fd9f50df534 Successfully built 1fd9f50df534 Successfully tagged dongmu-springboot-project:latest
10：利用镜像运行容器
[root@iZwz9hv1phm24s3jicy8x1Z idea]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE dongmu-springboot-project latest 1fd9f50df534 About a minute ago 661MB redis 5.0.9-alpine3.11 3661c84ee9d0 24 months ago 29.8MB tomcat 9.0.22 c856951ade0a 2 years ago 624MB java 8 d23bdf5b1b1b 5 years ago 643MB [root@iZwz9hv1phm24s3jicy8x1Z idea]# docker run -d -P --name dongmu-springboot-web dongmu-springboot-project c63282034de4e9dca727c93009e29f421bcd2544557a60b6339fa8056cc1d0d5
11：测试访问
[root@iZwz9hv1phm24s3jicy8x1Z idea]# docker ps

访问成功上面是内部访问，下面我们重新启动利用外网进行访问
[root@iZwz9hv1phm24s3jicy8x1Z idea]# docker run -d -p 3344:8080 --name dongmu-springboot-web dongmu-springboot-project 35f3b4fe0f9a4b878d6566a9f4334fc98e7841b1fc5eb7869dd0044d4fb44d6d
