Python Docker的形象需要很长时间才能建立,python,docker,dockerfile,debian-buster,Python,Docker,Dockerfile,Debian Buster,以下是Dockerfile的内容，我将其从alpine图像更改为slim buster图像。我真的很难理解为什么它花了这么长时间，我想这与我在apt get update中更新和安装的所有AP有关。我可能正在重新安装我不需要的软件包，或者做一些我不需要的事情，有没有办法加快速度 # pull official base image FROM python:3.8-slim-buster # set work directory WORKDIR /opt/workspace # set env

编辑： 收到答复后，我已将dockerfile更新为以下内容。请记住，我需要使用apt get安装的唯一软件包是运行wkhtmltopdf所需的软件包！它现在运行得快多了，而且工作得好多了

这里有很多问题。首先，有些软件包是您不需要的：

您安装了两次python。您正在安装Debian-python包

python

，但是Docker

python

映像有自己的python版本（在/usr/local中），其中已经有dev头文件。您不需要这样做，它可能会导致混淆，因为您最终会得到两个版本的Python（）

musl-dev是不必要的。Debian使用glibc，而不是musl。我怀疑这是阿尔卑斯山留下来的

您正在安装一个编译器，通常是一堆C头文件，所有这些*-dev包。很可能你根本不需要！在Alpine上，您需要编译所有内容，因为Alpine不能使用普通的二进制轮子。（）由于您使用的是Debian，很可能您所有的依赖项都有二进制轮子。您仍然需要为自己的代码编写一个编译器，但如果它是纯Python，则很可能不是

因此，我的建议是：只需删除整个

apt get

行。很有可能没有它它也能正常工作。
