markmcculloh/scratchx repository overview

⁠ScratchX - A scratch image + tiny executable

This is (hopefully) the smallest possible docker image that can be successfully executed. It is based on the scratch⁠ base image with the addition of the following compiled assembly:

SECTION .text align=1
GLOBAL _start
_start:
    mov       al, 60
    syscall

The actual image size is 124 bytes and the tgz file is ~1.3KB.

Note that is is currently only for linux/amd64 platform as the it is assembled as a elf64 binary.

⁠Usage

Running the image will immediately exit with 0.

docker pull markmcculloh/scratchx
docker run markmcculloh/scratchx

The image is also commited as a tarball in this repository.

⁠Why

Other than for fun, this image can be used as a base for images that need to only contain files rather than anything executable.
