1、创建一个SpringBooot项目并且打成jar包

2、在Linux中创建一个文件夹,来做docker测试

[code] [root@izwz90lvzs7171wgdhul8az ~]# mkdir /root/docker_test[/code]

3、将jar包上传到Linux中

创建存放jar包的文件夹

[code] [root@izwz90lvzs7171wgdhul8az docker_test]# mkdir /root/docker_test/jar[/code]

然后利用XShell上传jar包到上面的文件夹中

4、编写Dockerfile文件

[code] # 基于java镜像创建新镜像 FROM java:8 # 作者 MAINTAINER Howinfun # 将jar包添加到容器中并更名为app.jar ADD jar/app.jar /root/docker_test/app.jar # 运行jar包 ENTRYPOINT ["nohup","java","-jar","/root/docker_test/app.jar","&"][/code]

注意:ADD 、 COPY 指令用法一样,唯一不同的是 ADD 支持将归档文件(tar, gzip, bzip2, etc)做提取和解压操作。还有需要注意的是,COPY 指令需要复制的目录一定要放在 Dockerfile 文件的同级目录下。

5、制作镜像

[code] [root@izwz90lvzs7171wgdhul8az docker_test]# docker build -t sbdemo .[/code]

命令参数:

-t:指定新镜像名
.:表示Dockfile在当前路径

如果我们的 Dockerfile 文件路径不在这个目录下,或者有另外的文件名,我们可以通过 -f 选项单独给出 Dockerfile 文件的路径

[code] [root@izwz90lvzs7171wgdhul8az docker_test]# docker build -t sbdemo -f /root/docker_test/Dockerfile /root/docker_test/[/code]

命令参数:

-f:第一个参数是Dockerfile的路径 第二个参数是Dockerfile所在文件夹制作完成后通过docker images命令查看我们制作的镜像:

[code] [root@izwz90lvzs7171wgdhul8az docker_test]# docker images | grep sbdemo sbdemo latest 7efac46ef997 4 hours ago 686MB[/code]

6、启动容器

[code] [root@izwz90lvzs7171wgdhul8az docker_test]# docker run -d -p 8888:8888 --name mysbdemo sbdemo:latest[/code]

命令参数:

-d:后台运行
-p:公开指定端口号
--name:给容器命名

启动后可通过docker ps查看正在运行的容器:

[code] [root@izwz90lvzs7171wgdhul8az docker_test]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 5096c8c7b36f sbdemo "nohup java -jar /ro?? 4 seconds ago Up 2 seconds 0.0.0.0:8888->8888/tcp mysbdemo[/code]

7、查看容器启动日志

我们可以通过 docker logs 查看指定容器的日志:

[code] [root@izwz90lvzs7171wgdhul8az docker_test]# docker logs mysbdemo . ____ _ __ _ _ /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ \\/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v2.1.6.RELEASE) 2019-10-11 02:10:46.264 INFO 1 --- [ main] com.hyf.DatabaseApplication : Starting DatabaseApplication v0.0.1-SNAPSHOT on 6d85ac5d8751 with PID 1 (/root/docker_test/app.jar started by root in /) 2019-10-11 02:10:46.267 DEBUG 1 --- [ main] com.hyf.DatabaseApplication : Running with Spring Boot v2.1.6.RELEASE, Spring v5.1.8.RELEASE 2019-10-11 02:10:46.268 INFO 1 --- [ main] com.hyf.DatabaseApplication : No active profile set, falling back to default profiles: default 2019-10-11 02:10:49.139 WARN 1 --- [ main] o.m.s.mapper.ClassPathMapperScanner : Skipping MapperFactoryBean with name 'bookMapper' and 'com.hyf.mapper.BookMapper' mapperInterface.

8、访问接口

容器启动后,我们尝试使用postman或者其他http工具去访问部署在容器中的应用接口。
