无法在python v3.9.6或更高的基本映像中找到package PostgreSQLClient-11

Question

FROM python:3.9.5

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

对于上面的Dockerfile，docker build命令工作平稳。

但

FROM python:3.9.6

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

docker build引发以下错误。

#5 2.088 Get:6 http://deb.debian.org/debian bullseye-updates/main amd64 Packages [2592 B]

无法在pythonv3.9.6或基础映像中找到PostgreSQLClient-11包

Answer 1

这个对我有用

FROM python:3.9.6-buster

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

看起来bullseye版本(默认情况下是python3.9.6映像)没有postgresql-client-11库，但是buster版本有它。

为了更干净的安装，试试这个吧：

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
