add

In Dockerfiles, the `COPY` and `ADD` commands are used to add files to images, but they serve different purposes. `COPY` is straightforward, ideal for transferring local files to the image without additional processing. `ADD`, on the other hand, can handle URL sources and automatically extract compressed files. It’s advisable to use `COPY` for simplicity and clarity unless the additional capabilities of `ADD` are required. Understanding when to use each command helps in creating more efficient and secure Docker images.
