COPY [files...] [destination]
COPY instruction moves files from your repository to the runner.
Files can be:
- relative (to the layerfile location for sources, and WORKDIR location, or /root if not specified for destination)
- absolute (from the root of the repository for sources, and filesystem root for destination)
COPY . .to copy the directory containing the Layerfile to the current working directory (or /root if WORKDIR has not been used)
COPY package.json yarn.lock ./to copy those two files to the current directory.
COPY / /rootto copy the entire repository to /root in the runner.
