有了docker之后是否开放应用是否不需要考虑多用户了？

Question

例如在有docker之前，用php开发了一套微信后台，由于需要卖给多个用户，所以需要在设计时考虑多用户支持，使用一个数据库。但有了docker之后，完全可以只考虑单用户，卖个多个用户新建多个容器即可。那么是不是说就不用考虑多用户了？

What he said seemed to make sense, but I was speechless.

Speaking of which, in the past, wasn’t it okay to give the code directly to others? Isn’t it just a matter of creating a new folder?
Why use docker?
How many changes will be needed to fix the BUG?

Besides, this thing sells WeChat platform and services, not software.
