Question

我正在构建一个python docker映像并正在测试kinit功能。当我运行以下`os.system（'kinit'）时，我收到一个错误

FROM python:3.5.7-buster

ADD krb5.conf /etc/krb5.conf
ADD krb5.keytab /etc/krb5.keytab

COPY requirements.txt .

RUN apt-get update && apt-get install -y libsasl2-dev libsasl2-2 libsasl2-modules-gssapi-mit openssl libkrb5-dev krb5-config kinit kinit-dev
RUN pip install --no-cache-dir -r requirements.txt

要求：

impyla==0.15.0 sasl==0.2.1 thrift_sasl==0.2.1 thriftpy==0.3.9 thriftpy2==0.4.0 numpy pandas openssl-python==0.1.1 kerberos

Python代码：

import ssl
from impala.dbapi import connect
import os

os.system("kinit")

我收到错误sh: 1: kinit: not found

Answer 1

kinit Debian软件包与Kerberos不相关：

# apt-cache search kinit
kinit - process launcher to speed up launching KDE applications
kinit-dev - process launcher to speed up launching KDE applications

包含/usr/bin/kinit二进制文件的软件包是krb5-user软件包：

# dpkg -S /usr/bin/kinit
krb5-user: /usr/bin/kinit

# apt-cache search krb5-user
krb5-user - basic programs to authenticate using MIT Kerberos

您的Dockerfile应该如下所示：

FROM python:3.5.7-buster

ADD krb5.conf /etc/krb5.conf
ADD krb5.keytab /etc/krb5.keytab

COPY requirements.txt .

ENV DEBIAN_FRONTEND=noninteractive
RUN apt-get update && apt-get install -y libsasl2-dev libsasl2-2 libsasl2-modules-gssapi-mit openssl libkrb5-dev krb5-config krb5-user
RUN pip install --no-cache-dir -r requirements.txt

注意：krb5-user安装是交互式的，您需要将DEBIAN_FRONTEND=noninteractive设置为make it unattended。

运行os.system（“ kinit”）时发生Python错误-sh：1：kinit：未找到
