I will provide the translated code segments as per your request. Here's the translated content:
FROM python:3.8.0-alpine
WORKDIR /home/flask
ADD . /home/flask
RUN apk --no-cache add --update --virtual .build-editdistance gcc g++ && \
apk --no-cache add libsasl libldap openssl && \
apk --no-cache add --update --virtual .libs libstdc++ && \
apk add linux-headers && \
apk add unixodbc-dev;
RUN rm -rf /var/cache/apk/* && \
pip install --upgrade pip && \
pip install --upgrade setuptools && \
pip install --no-cache-dir -Ur requirements.txt && \
apk del .build-editdistance;
EXPOSE 5000
Please let me know if you need further assistance or additional translations.

I am trying to pip install python-ldap in Docker but am missing lber.h. I need python-ldap because I am trying to implement an OS agnostic SSO for my application, following this for now and hoping it doesn't break the rest of my app https://code.tutsplus.com/tutorials/flask-authentication-with-ldap--cms-23101
I have tried
RUN apk add libsasl2-dev libldap2-dev libssl-dev
and
RUN apk --no-cache add libsasl2-dev libldap2-dev libssl-dev
but I get the following error:
ERROR: unsatisfiable constraints:
libldap2-dev (missing):
required by: world[libldap2-dev]
libsasl2-dev (missing):
required by: world[libsasl2-dev]
libssl-dev (missing):
required by: world[libssl-dev]
Having gone to https://pkgs.alpinelinux.org/packages?name=libldap2-dev&branch=edge I feel that it is possible that these packages do indeed not exist within the alpine python image. Therefore, I tried substituting the installations with packages that exist in the above link, namely: openssl libsasl libldap
This didn't work either and had the same effect as not installing any of the packages i.e. the header missing error appeared:
Modules/constants.h:7:10: fatal error: lber.h: No such file or directory
#include "lber.h"
^~~~~~~~
compilation terminated.
error: command 'gcc' failed with exit status 1
as a result of /tmp/pip-install-doifa8k9/python-ldap/
My Dockerfile:
FROM python:3.8.0-alpine
WORKDIR /home/flask
ADD . /home/flask
RUN apk --no-cache add --update --virtual .build-editdistance gcc g++ && \
apk --no-cache add libsasl libldap openssl && \
apk --no-cache add --update --virtual .libs libstdc++ && \
apk add linux-headers && \
apk add unixodbc-dev;
RUN rm -rf /var/cache/apk/* && \
pip install --upgrade pip && \
pip install --upgrade setuptools && \
pip install --no-cache-dir -Ur requirements.txt && \
apk del .build-editdistance;
EXPOSE 5000

对于Alpine Python在Docker中的情况：
使用以下命令而不是：
这在https://stackoverflow.com/questions/4768446/i-cant-install-python-ldap中有答案，但答案被深埋并且被接受的答案所混淆（libsasl libldap openssl来自哪里），因此保留这个特定于Docker的问题是一个好主意。
英文:
For alpine python in docker:
apk add openldap-dev
instead of
apk add libsasl libldap openssl
This is answered in https://stackoverflow.com/questions/4768446/i-cant-install-python-ldap but the answer is buried sufficiently deep and obfuscated by the accepted answer ( which is where libsasl libldap openssl came from) that it would be a good idea to keep this docker specific question
