I'm taking a docker image, ubuntu/python:3.12-24.04_stable.
Dockerfile
FROM ubuntu/python:3.12-24.04_stable
RUN apk update
When I build this simple Dockerfile, I get exit code: 1. Is this docker image not available /bin/sh?
docker build -t test -f Dockerfile .

I've tried using python:3.12 and ubuntu:24.04 and all of them are working fine but the image only ubuntu/python:3.12-24.04_stable is returning the error to have RUN or so.

- From my understanding, this image consists only python but what I dont get is, the image is based on ubuntu, its wrapped up with python 3.12. So, how come is this available only for python if this is the case – Hashimotto Jo Commented Mar 19 at 14:53
- Even if the apt command worked, it would only bloat the image. You should include the actual goal you are trying to achieve in the question since this is quite possibly an XY Problem. – BMitch Commented Mar 19 at 15:04

Reset to default 0This is equivalent to a distroless image:
This image is a chiselled Ubuntu rock that contains only the Python runtime and its standard libraries. It is production-ready and can also be used as a base if additional application dependencies are needed.
(Source: the Hub overview)
The image contains no shell, no apt package manager, or anything other than the python binary and its dependencies:
