The official documentation can be found here.

apk: not found, even with python:3.9-alpine – Docker

I am trying to build docker image:

FROM python:3.9-alpine

ENV PYTHONDONTWRITEBYTECODE=1
ENV PYTHONUNBUFFERED=1
...

But, I got this error:

As I know, the most popular issue is using non-Alpine image and trying to access apk manager. But, I can’t understand, what’s wrong with mine.

    I believe u have to add a runtime dependencies inside your docker file. trying adding this command inside your docker file

    FROM python:3.9-alpine

# ensure local python is preferred over distribution python
ENV PATH /usr/local/bin:$PATH

#add runtime dependencies
RUN apk add --no-cache

ENV PYTHONDONTWRITEBYTECODE=1
ENV PYTHONUNBUFFERED=1

    The error is here

    ENV PATH="/scripts:{PATH}"

    Change it to

    ENV PATH="/scripts:${PATH}"
