本文分享了使用Docker创建数据库容器的经验，特别是针对通过主从复制实现数据流复制的场景。文章提到了Windows家庭版不支持Docker CE，并讨论了解决安装过程中遇到的问题的方法。此外，还提供了一个解决运行PostgreSQL初始化设置时遇到D-Bus失败问题的具体命令。

To share the experiences to create docker containers of databases, for stream duplication of data via master and slave.

Windows home additon does not support Docker ce for windows.
- You may encounter error when installing Docker with the installer downloaded from the official website.

Database services should be run standalone when the new container is created.
- You may encounter D-Bus failure when you want to run the "posgresql*.*-setup initdb". This is solvable if your create a standalone command when creating the new container.

~$ sudo docker run -d --name=containername --privileged=true imagename:tagname /usr/sbin/init

- "run" is equavilent to "create";
- -d means the command is working at background;
- --name gives the name of your container;
- --privileged specifies the root privilege in the container;
- imagename:tagname gives the image used to create the container;
- /usr/sbin/init is the guard process running for -d.
"exec" works better than "attach".
- attach does not have rich options to run script in the container.
