missing unix commands in slim image

[gurolakman]

i tried out docker-slim on one of our in-house images & obtained the following results:

REPOSITORY TAG IMAGE ID CREATED SIZE
com/xyz/sample/docker.slim latest 5c2d0aca41c7 3 minutes ago 112MB
com/xyz/sample/docker latest d1394f2120aa 12 minutes ago 724MB

which clearly looked impressive.

when i tried to make use of the new image (e.g., start a container that uses it) however, i ran into trouble w/ some basic commands used by an in-house <kickstart.sh> bash script not being found.

$ sudo docker run -it -v /tmp:/tmp --name sample -p 8015:8015 --add-host test1:10.0.1.231 --add-host test4:10.0.1.234 com/xyz/sample/docker.slim -native /bin/bash
=== Creating /xyz/admin/sample.conf ===
/xyz/bin/kickstart.sh: line 40: mkdir: command not found
=== Created /xyz/admin/sample.conf:
/xyz/bin/kickstart.sh: line 43: cat: command not found
=== Executing (native) /bin/bash

this makes me think i must be overlooking something rather obvious. any thoughts?

thanks in advance.

The same problem here - even the ls and pwd commands are missing in an image, based on Ubuntu 20.04

@mmaker1234 what kind of application do you have in your image? Also note that the shell and its related components will be removed unless it's used by the application or you ask for it explicitly (e.g., there's a flag called --include-shell, which provides a way to keep a basic read-only shell in your minified image).
