FROM python:3.9.5

RUN apt-get update && apt-get install -y  postgresql-client-11

for Dockerfile above, docker build commands works smoothly.

But

FROM python:3.9.6

RUN apt-get update && apt-get install -y  postgresql-client-11

docker build throws the following error.

This works for me

FROM python:3.9.6-buster

RUN apt-get update && apt-get install -y  postgresql-client-11

Looks like the bullseye version (by default for python:3.9.6 image) does not have postgresql-client-11 library, but the buster version have it.

Try this for cleaner install:

FROM python:3.10.4-alpine3.16

# set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1


RUN pip install --upgrade pip

# copy project install deps
# install deps for psycopg build and run pip
RUN apk add --update --no-cache postgresql-client jpeg-dev
RUN apk add --update --no-cache --virtual .tmp-build-deps \
    gcc libc-dev linux-headers postgresql-dev musl-dev zlib zlib-dev libffi-dev


WORKDIR /api
COPY requirements.txt requirements.txt
RUN pip install -r ./requirements.txt
RUN apk del .tmp-build-deps
