Question

我是docker的新手，并且已经构建了一个自定义容器来在我的云服务器上运行我的Spider。我的scraper是使用python 3.6，scrapy 1.6，Selenium构建的，并使用docker在一个容器中运行所有内容。启动蜘蛛时，我有scrapy open_spider方法，该方法在目录中运行另一个python脚本，该脚本生成了scrapy进行爬网的网址。该脚本将链接保存在文本文件中，但是，我得到PermissionError：[Errno 13]权限被拒绝：'tmp。

我尝试在tmp文件夹上运行chmod 777和a + rw，因此它将允许我创建文本文件，但仍然出现权限被拒绝的错误。我已经研究了好几天了，却找不到解决方法。

笔记本电脑上的操作系统是ubuntu 18.04。

下面是指向我的docker文件的链接

Dockerfile

在此链接到我的setup.py文件

Answer 1

将以下内容添加到您的Dockerfile中：

RUN adduser --disabled-login dockeruser
USER dockuser
RUN chown dockuser:dockuser -R /tmp/

注意：如果--disabled-login也无效，请使用--disabled-password

Answer 2

也许是以下行中的“ setup.py”文件：

RUN python setup.py install

需要以适当的权限执行吗？

Docker PermissionError：[Errno 13]权限被拒绝：'tmp'
