在docker build上pip安装失败

标签: python docker ssl

我遇到一个奇怪的问题。我关注了Dockerfile

FROM openjdk:8-jre-alpine3.8

WORKDIR /app


RUN apk --no-cache add curl bash g++ postgresql-dev python3-dev
COPY requirements.txt /app
RUN pip3 install -r requirements.txt
...

我正在使用命令docker build -t mydocker .构建它。它在其他计算机上可以正常运行,但在我的计算机上失败,并出现以下错误:

该错误提到了名称fireonskull.com,这对我来说听起来很熟悉。我曾经在计算机上拥有该域的SSL证书。

但是docker build与我系统上的文件有什么关系。 pip install在主机OS上也可以正常工作。请帮忙!

答案 0 :(得分:4)

一个肮脏的快速修复程序可能是定义容器在构建命令中应使用的dns:

docker build --dns=1.1.1.1 -t mydocker .

但这当然不能解决根本原因。 @kichik在上面的评论中有提到。您需要调试名称的解析方式。我宁愿从交互式外壳中做到这一点。

docker run -ti openjdk:8-jre-alpine3.8 sh

首先签出使用什么dns服务器:

cat /etc/resolv.conf

我得到名称服务器192.168.65.1,它是主机

现在安装bind-tools进行挖掘和查询pypi.org

apk add bind-tools
dig pypi.org

应该会给您一个看起来像这样的答案:

; <<>> DiG 9.12.3 <<>> pypi.org

您的答案很可能会向您显示dns无法正确解析。要获取有关如何解析域的更多信息,请使用dig的+ trace选项

dig +trace pypi.org

那应该有望揭示出响应错误地址的情况。

鉴于它可以在您的主机操作系统上运行,听起来好像您在Docker配置中具有代理设置。

打开您的docker偏好设置,然后转到代理选项卡以查看。

Docker proxy settings

它也可能在您的〜/ .docker / config.json中。像这样:

{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://127.0.0.1:3001",
     "httpsProxy": "http://127.0.0.1:3001",
     "noProxy": "*.test.example.com,.example2.com"
   }
 }
}

答案 1 :(得分:1)

据我所知,您在SSL检查/验证方面遇到了问题。 尝试在pip安装步骤中添加它:

pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org -r requirements.txt

答案 2 :(得分:-3)

鉴于您正在从openjdk映像运行,它没有ptyhon所需的所有内容,请将其添加到您的dockerfile中

RUN apt-get update && apt-get install -y --no-install-recommends \
    python3.6 \
    python3-pip \
    && \
apt-get clean && \
