This directory stores all files that should be copied to the rootfs of a Docker container. The files should be stored according to the correct directory structure of the destination container. For example:
rootfs/bin -> /bin
rootfs/usr/local/share -> /usr/local/share
A Dockerfile in the rootfs is used to build the image. Where possible, compilation should not be done in this Dockerfile, since we are interested in deploying the smallest possible images.
Example:
FROM alpine:3.2
COPY . /
ENTRYPOINT ["/usr/local/bin/boot"]
