# FROM scratch
This image is most useful in the context of building base images (such as debian and busybox) or super minimal images (that contain only a single binary and whatever it requires, such as hello-world).
As of Docker 1.5.0 (specifically, docker/docker#8827), FROM scratch is a no-op in the Dockerfile, and will not create an extra layer in your image (so a previously 2-layer image will be a 1-layer image instead).

scratchappears in Docker’s repository on the hub, you can’t pull it, run it, or tag any image with the namescratch. Instead, you can refer to it in yourDockerfile. For example, to create a minimal container usingscratch:

COPY hello /
CMD ["/hello"]Recommend
