1.场景
|
1 |
stringboot - > spring boot .jar -> dockerfile---> run dokcerfile |
2.编写springboot 项目打包上传linux服务器
2.1 将jar 包和 docker放到同一个目录
|
1 2 3 4 |
-rw-r--r-- 1 root root 19514674 2月 27 22:48 myspringbootdocker.jar [root@basenode springbootdocker] # pwd /opt/springbootdocker [root@basenode springbootdocker] # |
2.2 编写dockerfile
1.需要注意的是 jar包名字不能有大写
2.Dockerfile 的文件名 首字母D 必须大写
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
[root@basenode springbootdocker] # vi Dockerfile
# 基础镜像使用java FROM java:8 # 作者 MAINTAINER wudl # VOLUME 指定临时文件目录为/tmp，在主机/var/lib/docker目录下创建了一个临时文件并链接到容器的/tmp VOLUME /tmp # 将jar包添加到容器中并更名为zzyy_docker.jar ADD myspringbootdocker.jar /myspringbootdocker .jar # 运行jar包 RUN bash -c 'touch /myspringbootdocker.jar' ENTRYPOINT [ "java" , "-jar" , "/myspringbootdocker.jar" ] #暴露18088端口作为微服务 EXPOSE 18088 |
3. 运行dockerfile
命令 docker build -t myspringbootdocker:1.6 .

4.查看镜像

5. 运行镜像
