Why is venv not saved in a Docker container?

Question

Python

I'm trying to create a virtual environment container based on Python 3.10.4 on Alpine Linux:

Dockerfile

FROM python:alpine3.14

VOLUME /home/project
WORKDIR /home/project

RUN python -m venv env

If you go into the container and look at the files, then there is no virtual environment.
I tried to create and activate instead of an empty creation:
RUN python -m venv env && source env/bin/activate
It still gives an error that the virtual environment has not been created.
What is the problem?

Answer 1

FROM python:alpine3.14

WORKDIR /home/project

RUN python -m venv /home/project/env
