1.场景
stringboot - > spring boot .jar -> dockerfile---> run dokcerfile2.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
-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
[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 180883. 运行dockerfile
命令 docker build -t myspringbootdocker:1.6 .
[root@basenode springbootdocker]# docker build -t myspringbootdocker:1.6 .
