试图在docker镜像上安装selenium python3包

我尝试用selenium python包重新构建一个docker镜像是不成功的。我不知道该怎么办。

这是我的dockerfile:

FROM selenium/standalone-chrome:latest
WORKDIR /usr/local/bin
RUN sudo apt-get update
RUN sudo apt-get install software-properties-common
RUN sudo apt-add-repository universe
RUN sudo apt-get install python-pip
RUN pip3 install -r requirements.txt
RUN pip3 install .
RUN pip3 install -e .
COPY ./* ./

我很确定这是我的dockerfile错了,但是在尝试了各种安装pip的方法后,我正在画一个空白。

无论如何我都会打电话:     docker build -t webdriver。

其中输出以下内容:

我猜“你想继续吗?[Y / n] Abort。”需要回答“Y”,但我不知道该怎么做。我怀疑我错过了更多。

毋庸置疑,我的python脚本仍然无法运行,因为它需要selenium:

Traceback (most recent call last):
  File "web-test.py", line 3, in <module>
    from selenium import webdriver

谁能告诉我哪里出错了?

您已正确识别错误。您需要回答问题:Do you want to continue? [Y/n]Y,然后继续。因此,按如下所示更改您的docker文件并添加标志-y

FROM selenium/standalone-chrome:latest
WORKDIR /usr/local/bin
RUN sudo apt-get -y update
RUN sudo apt-get install -y software-properties-common
RUN sudo apt-add-repository -y universe
RUN sudo apt-get install -y python3-pip
RUN pip3 install -r requirements.txt
RUN pip3 install .
RUN pip3 install -e .
COPY ./* ./

-y标志可用于假设YES用于所有apt安装。您需要添加-y标志,因为docker build命令不能在交互模式下运行。因此,必须在Dockerfile中添加构建过程中的所有交互。 (Read this answer

由于要使用pip3,因此需要正确安装。您正在尝试安装pip2。我已经相应地更新了您的docker文件。您需要使用以下命令来安装pip3。

RUN sudo apt-get install -y python3-pip

您的Dockerfile中有几件事:

  • 避免安装或使用 sudo ,因为它具有不可预测的TTY和信号转发行为,可能会引起问题。您可以参考Dockerfile Best Practice
RUN sudo apt-get update
RUN sudo apt-get install software-properties-common
RUN sudo apt-add-repository universe
RUN sudo apt-get install python-pip

您需要在上面的Docker命令中添加标志-y,以便在Docker构建期间,它可以自动为您说出Yes
