What is a difference between COPY and ADD instructions in Docker?
Experience Level: Senior
Tags: Docker
Answer
COPY only supports the basic copying of local files into the container, while ADD has some features (like local-only tar extraction and remote URL support) that are not immediately obvious. Consequently, the best use for ADD is local tar file auto-extraction into the image, as in ADD rootfs.
