Docker通过DockerFile构建MySQL失败

Question

使用Dockerfile构建MySQL，COPY进去一个sql脚本和sh脚本，想在构建mysql的新建一个表，但是新建不出来。我通过exec的方式进入构建好的镜像，然后运行sh脚本，可以正确执行sql脚本并建表。

Dockerfile

FROM mysql:5.7

#设置免密码登陆
ENV MYSQL_ALLOW_EMPTY_PASSWORD yes 
#ENV MYSQL_ROOT_PASSWORD=MYSQL_ROOT_PASSWORD=123456
ENV MYSQL_USER=admin
ENV MYSQL_PASSWORD=123456ex

#导入启动脚本
COPY setup.sh /mysql/setup.sh
COPY patent.sql /mysql/patent.sql
#COPY admin.sql /mysql/admin.sql

#设置工作目录
WORKDIR /mysql

#设置容器启动时执行的命令
#CMD ["sh", "/mysql/setup.sh"]
RUN ["sh", "/mysql/setup.sh"]

setup.sh

#!/bin/bash
echo hello world
echo `service mysql status`
service mysql start
echo `service mysql status`
mysql  < /mysql/patent.sql
echo OVERRRRRR

sql脚本太长了，我不贴了，本机测试通过。

build命令行输出
