I am trying to use Selenium on one of my airflow tasks. I have airflow running on apache/airflow:2.1.4 docker image.
I get the following error when I use selenium in my airflow task (since I'm missing firefox)
FileNotFoundError: [Errno 2] No such file or directory: 'firefox': 'firefox'
How would I go about adding geckodriver and firefox to the airflow image?
I have my docker-compose build the following Dockerfile for airflow,
FROM apache/airflow:2.1.4
WORKDIR /python_dependencies
COPY ./requirements.txt .
RUN pip3 install -r requirements.txt

apache/airflow:2.1.4 is based on debian, so you just need to use apt-get install firefox-esr to get firefox command, while download pre-built binary from geckodriver github to install geckodriver.
Dockerfile:
FROM apache/airflow:2.1.4
USER root
RUN apt-get update \
&& apt-get install -y --no-install-recommends \
ca-certificates curl firefox-esr \
&& rm -fr /var/lib/apt/lists/* \
&& curl -L | tar xz -C /usr/local/bin \
&& apt-get purge -y ca-certificates curl
USER airflow
Verify:
$ docker build -t abc:1 .
$ docker run --rm -it --entrypoint=which abc:1 firefox
/usr/bin/firefox
$ docker run --rm -it --entrypoint=which abc:1 geckodriver
/usr/local/bin/geckodriver
