How add file to this image about busybox HOT 1 CLOSED

If you just want to run a C binary in a busybox container, then I think the hello-world image is a pretty good example. We use a separate dockerfile and image to build the static binary so that the toolchain (compiler) is self contained, and then we copy the binary into the image with another dockerfile. We do FROM scratch for a super tiny container, but it has the drawback of zero debugging since there is no other binary in the image.

The process we use to build, and extract the binaries is contained in [update.sh]https://github.com/docker-library/hello-world/blob/f98ccd0399cf3c17a73693448bd6f652c3cf336e/update.sh:

docker build -f Dockerfile.build -t hello-world:build .
rm -rf */hello
docker run --rm hello-world:build sh -c 'tar --create */hello' | tar --extract --wildcards '*/hello'

from busybox.
