Chromedriver executable path not found in Docker Container

Question

I have created a docker image with the Docker file below. It installs the latest versions of Google Chrome and the chrome driver. As well as the other pip packages.

Dockerfile

FROM python:3.9

# Install Chrome WebDriver
RUN CHROMEDRIVER_VERSION=`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE` && \
    mkdir -p /opt/chromedriver-$CHROMEDRIVER_VERSION && \
    curl -sS -o /tmp/chromedriver_linux64.zip http://chromedriver.storage.googleapis.com/$CHROMEDRIVER_VERSION/chromedriver_linux64.zip && \
    unzip -qq /tmp/chromedriver_linux64.zip -d /opt/chromedriver-$CHROMEDRIVER_VERSION && \
    rm /tmp/chromedriver_linux64.zip && \
    chmod +x /opt/chromedriver-$CHROMEDRIVER_VERSION/chromedriver && \
    ln -fs /opt/chromedriver-$CHROMEDRIVER_VERSION/chromedriver /usr/local/bin/chromedriver

# Install Google Chrome
RUN curl -sS -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-chrome.list && \
    apt-get -yqq update && \
    apt-get -yqq install google-chrome-stable && \
    rm -rf /var/lib/apt/lists/*


COPY requirements.txt .

RUN pip install -r requirements.txt

WORKDIR /seltesting

COPY ./app ./app

CMD ["python", "./app/main.py"]

The chromedriver.exe file is in the container as I have found it in the CLI. It is in this directory '/usr/local/bin/chromedriver'.

python code

driver = webdriver.Chrome(options=options, executable_path='/usr/local/bin/chromedriver')

I am using a venv as I am also using flask to create a micro service that uses the chrome driver. Would that be causing an issue?

Any assist would be much appreciated as I have been stuck on this for a long time.

I have found the problem, you need to add the all the python files into the Dockerfile. Please find the Dockerfile to install the Chromedriver and Chrome onto the image and the default path for the chromedriver within the container.

Dockerfile

FROM python:3.9

ADD /app/main.py .
ADD /app/connectdriver.py .

# Install Chrome WebDriver
RUN CHROMEDRIVER_VERSION=`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE` && \
    mkdir -p /opt/chromedriver-$CHROMEDRIVER_VERSION && \
    curl -sS -o /tmp/chromedriver_linux64.zip http://chromedriver.storage.googleapis.com/$CHROMEDRIVER_VERSION/chromedriver_linux64.zip && \
    unzip -qq /tmp/chromedriver_linux64.zip -d /opt/chromedriver-$CHROMEDRIVER_VERSION && \
    rm /tmp/chromedriver_linux64.zip && \
    chmod +x /opt/chromedriver-$CHROMEDRIVER_VERSION/chromedriver && \
    ln -fs /opt/chromedriver-$CHROMEDRIVER_VERSION/chromedriver /usr/local/bin/chromedriver

# Install Google Chrome
RUN curl -sS -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-chrome.list && \
    apt-get -yqq update && \
    apt-get -yqq install google-chrome-stable && \
    rm -rf /var/lib/apt/lists/*

COPY requirements.txt .

RUN pip install -r requirements.txt

WORKDIR /seleniumtesting

COPY ./app ./app


CMD ["python","./app/main.py"]

python driver script

driver = webdriver.Chrome(options=options, executable_path='/usr/local/bin/chromedriver')
