Docker - MySQL容器不能继续运行(Docker - MySQL container does not keep running)

 我需要一些帮助在Docker容器中使用MySQL。 我认为Docker的全部意义在于隔离沙箱中的进程并让它们像正常进程一样运行 - 我没有得到这个功能。 
 
 每当我运行一个我自己的图像构建的MySQL容器时，它运行2秒钟，然后停止。 尝试使用docker run -i -t <imageid>给我这个： 
 
root@CenturionX:/home/centurionx/Code/Git/gdms-rcon# docker run -i -t e2d
150221 05:25:21 mysqld_safe Logging to '/var/lib/mysql/28123b6d1dad.err'.
150221 05:25:21 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
150221 05:25:21 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended
root@CenturionX:/home/centurionx/Code/Git/gdms-rcon# 
 
 为什么守护进程不能保持打开状态？ 我有我的Dockerfile ，看起来像： 
 
# This docker file constructs a MySQL database instance
FROM mysql:latest

ADD . /gdms-rcon/mysql
WORKDIR /gdms-rcon/mysql

ENTRYPOINT ["/usr/bin/mysqld_safe"]

EXPOSE 3306
 
 还有一个fig.yml文件来帮助我自动化构建过程： 
 
mysql:
  build: .
  volumes:
    - .:/gdms-rcon/mysql
  working_dir: /gdms-rcon/mysql
  ports:
    - "3306:3306"
  environment:
    - MYSQL_DATABASE=mydb
    - MYSQL_ROOT_PASSWORD=mypassword

I need some help with using MySQL in a Docker container. I thought the entire point of Docker was to isolate processes in sandboxes and have them run like normal processes - I am not getting this functionality.
 
Whenever I run a MySQL container that I have built from my own image, it runs for 2 seconds, then stops. Trying docker run -i -t <imageid> gives me this:
 
root@CenturionX:/home/centurionx/Code/Git/gdms-rcon# docker run -i -t e2d
150221 05:25:21 mysqld_safe Logging to '/var/lib/mysql/28123b6d1dad.err'.
150221 05:25:21 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
150221 05:25:21 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended
root@CenturionX:/home/centurionx/Code/Git/gdms-rcon# 
 
Why does the daemon not stay open? I have my Dockerfile, which looks like:
 
# This docker file constructs a MySQL database instance
FROM mysql:latest

ADD . /gdms-rcon/mysql
WORKDIR /gdms-rcon/mysql

ENTRYPOINT ["/usr/bin/mysqld_safe"]

EXPOSE 3306
 
And a fig.yml file to help me automate the build process:
 
mysql:
  build: .
  volumes:
    - .:/gdms-rcon/mysql
  working_dir: /gdms-rcon/mysql
  ports:
    - "3306:3306"
  environment:
    - MYSQL_DATABASE=mydb
    - MYSQL_ROOT_PASSWORD=mypassword
