無法在 Docker 容器中安裝 Selenium chromedriver

Question

我正在使用這個 Dockerfile 在 Docker 容器中安裝 Selenium chromedriver：

FROM python:3.8

# install google chrome
RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
RUN sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list'
RUN apt-get -y update
RUN apt-get install -y google-chrome-stable

# install chromedriver
RUN apt-get install -yqq unzip
RUN wget -O /tmp/chromedriver.zip http://chromedriver.storage.googleapis.com/`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE`/chromedriver_linux64.zip
RUN unzip /tmp/chromedriver.zip chromedriver -d /usr/local/bin/

ENV DISPLAY=:99

COPY . /app

WORKDIR /app

RUN pip install --upgrade pip

RUN pip install -r requirements.txt

RUN chmod 755 ./run.sh

ENTRYPOINT ["/app/run.sh"]

前段時間我已經使用過這個 Dockerfile 並且一切正常。 現在，我在運行時收到此錯誤：

docker build -t container .

構建時的錯誤：

這里的問題是什么？

為什么不直接使用一個已經存在的圖像作為你的起點呢？ 例如，這看起來像是 chrome 和 python 的功能性 docker 映像：
