Dockerfile not installing google-chrome-CodePudding

I have written a Dockerfile based on python:3.9-slim-buster. I want to install chrome and chromedriver on top of this, but google-chrome package is not installing for some reason.

The Dockerfile:

FROM python:3.9-slim-buster

# set environment variables
ENV PIP_DISABLE_PIP_VERSION_CHECK 1
# don't write .pyc files
ENV PYTHONDONTWRITEBYTECODE 1 
# prevent Docker from buffering stdout
ENV PYTHONUNBUFFERED 1 

# set working directory
WORKDIR /code

COPY ./requirements.txt .
 
# add key and repository
# RUN sudo apt install software-properties-common apt-transport-https wget ca-certificates gnupg2 -y

# install dependencies
RUN apt-get update && apt-get install -y \
  gnupg2 \
  unzip \
  wget

# chrome repo
RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - \ 
    && echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list

RUN apt-get update && apt-get install -y \
  gcc \
  google-chrome-stable \
  less \
  libmagickwand-dev \
  libpq-dev \
  python3-selenium \
  vim \
  # && wget -O /tmp/chromedriver.zip http://chromedriver.storage.googleapis.com/`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE`/chromedriver_linux64.zip \
  # && unzip /tmp/chromedriver.zip chromedriver -d /usr/local/bin/ \
    && rm -rf /var/lib/apt/lists/* \
    &&  pip install -r requirements.txt

# copy project
COPY . .

Command output for trying to find google-chrome:

root@f9832abc0069:/code# apt list --installed | grep google

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

root@f9832abc0069:/code# google-chrome
bash: google-chrome: command not found

How can I install google-chrome on my docker image?

CodePudding user response：

RUN apt-get update && apt-get install -y \

Yeah, IIRC, apt-get update will return a non-zero code when there's something to update (like other programs do when there's an error), so everything after the && never gets executed¹. So, use ; instead.

¹ I consider this a design bug in apt-get update, by the way, since it's hard to know whether an error occured, e.g. unreachable network or the desired outcome was achieved, and the system now knows what to update. The apt-get man page is a shame for the debian project, imho, because it specifies none of that.

CodePudding user response：

I have copied your Dockerfile into an empty directory, then ran following commands inside :

$ cp /dev/null requirements.txt
$ docker build -t google-chrome .
$ docker run --rm -it -e DISPLAY=":0" -v /tmp/.X11-unix:/tmp/.X11-unix google-chrome google-chrome -no-sandbox

It worked without problem.

My environments :

$ docker -v
Docker version 20.10.17, build 100c701
$ cat /etc/os-release
