我有一个python脚本,我想集装箱化
test_remote.py
import os
import pwd
try:
userid = pwd.getpwuid(os.stat('.').st_uid).pw_name
except KeyError, err:
raise Exception('NIS Problem: userid lookup failed: %s' % err)
print "Hi, I am %s" % userid
运行良好
[eugene@mymachine workdir]# python test_remote.py
Hi, I am eugene
要在容器中运行此脚本,我编写了以下Dockerfile
# Use an official Python runtime as a parent image
FROM python:2.7-slim
WORKDIR /data
# Copy the current directory contents into the container at /app
ADD . /data
# Install any needed packages specified in requirements.txt
RUN pip install -r /data/requirements.txt
CMD ["python", "/data/br-release/bin/test_remote.py"]
当我运行图片时,它无法进行查找。
[eugene@mymachine workdir]# docker run -v testremote
Traceback (most recent call last):
File "/data/test_remote.py", line 27, in <module>
raise Exception('NIS Problem: userid lookup failed: %s' % err)
Exception: NIS Problem: userid lookup failed: 'getpwuid(): uid not found: 52712'
我尝试创建用户并通过在Dockerfile中添加以下行来运行它
RUN useradd -ms /bin/bash eugene
USER eugene
但我仍然收到错误查找失败错误
有什么建议吗? 我怎么会得到&#34; eugene&#34;来自test_remote.py,如果我不查看密码数据库。我想一种方法是将USERNAME设置为env var并让脚本解析它。
答案 0 :(得分:1)
这是你的问题:
userid lookup failed: 'getpwuid(): uid not found: 52712'
在Docker容器中,没有UID 52712的用户。您可以在构建映像时显式创建一个:
RUN useradd -u 52712 -ms /bin/bash eugene
或者您可以在运行主机时挂载/etc/passwd
:
docker run -v /etc/passwd:/etc/passwd ...
