Description
For items like files and directories that do not require ADD’s tar auto-extraction capability, you should always use COPY.
Read more about it here.
Bad Practice
FROM python:3.4
ADD requirements.txt /usr/src/app/
Recommended
FROM python:3.4
COPY requirements.txt /usr/src/app/
Exceptions
The best use for ADD is local tar file auto-extraction into the image.
