mysql 的 docker container

刚接触docker和mysql，想建立一个docker container，里面装个mysql。程序可以直接连接ontainer里的mysql。

这是Dockerfile
FROM ubuntu:14.04
# install mysql
RUN apt-get update
RUN DEBIAN_FRONTEND=noninteractive apt-get -y install mysql-server
ADD entrypoint.sh /entrypoint.sh
RUN chmod 755 /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]
EXPOSE 3306

这是`entrypoint.sh`

#!/bin/bash
mysql -uroot -e 'UPDATE mysql.user SET password=PASSWORD("rootpass") WHERE user="root"'
mysql -uroot -e 'FLUSH PRIVILEGES'

安装的时候好像出了问题，运行`sudo docker build -t test/devenv .`
Setting up mysql-server-5.5 (5.5.38-0ubuntu0.14.04.1) ...
invoke-rc.d: policy-rc.d denied execution of stop.
invoke-rc.d: policy-rc.d denied execution of start.

执行`sudo docker run -d -p 3306:3306 test/devenv`

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
2c0bfb09a8a0 test/devenv:latest /entrypoint.sh /bin/ 7 seconds ago Exited (1) 6 seconds ago berserk_nobel

执行`sudo docker run -i -t ubuntu /bin/bash`

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

大神们我这是要怎么修改？谢谢！
