When updating the version of software or data in database, it will took long time or be needed to test. 

We can just assign to another port with the mirror of website or mysql using docker.

For example, the current port of website is 1234 and the port of mirror is 4321. 

When test is finished, we just switch to 4321.

The user don't need to wait for updating.
