我有兴趣构建一个包含pip安装包的小型容器映像，但是不幸的是，通过apt-get安装python3-pip将依赖项（348MB）中的 lot 拉入到其他容器中很小的最小ubuntu映像（我目前正在使用dockerhub的<50MB account.save()
映像）：
ubuntu:xenial很多都是用于编译c模块。我想知道在构建容器时是否可以使用pip来安装python模块。
也许有一种编程方式可以安装pip，安装依赖项，然后在同一docker层中干净地卸载pip？
即（措辞）：
root@dce44a07a6a5:/home# apt-get install python3-pip

答案 0 :(得分：1)
如果您必须坚持使用Ubuntu，请使用apt-get install --no-install-recommends python3-pip。它仅占用33.9 MB，少10倍。最终成像为146M。
如果能够使用debian，请使用python:3.6-slim作为基础映像（138M），然后使用python:alpine（78.2M）进一步推送它。
在最后两种情况下，您可以使用python3 -m pip uninstall pip setuptools删除点，但是由于层开销，实际上会使它变大。
