I am junior developer and I am struggling with my current task at work. I need to run a script with cron inside a docker container and I am a little lost. My script is check.py, my DOCKERFILE is :
FROM ubuntu:latest
# Set the working directory to /app
WORKDIR /monitor-updates
# Copy the current directory contents into the container at /app
ADD . /monitor-updates
RUN \
apt-get update && \
apt-get install -y python python-dev python-pip python-virtualenv libmysqlclient-dev curl&& \
rm -rf /var/lib/apt/lists/*
RUN pip install --upgrade pip
RUN pip install -r requirements.txt
ADD my-crontab /
ADD check.py /
RUN chmod a+x check.py
RUN chmod a+x my-crontab
RUN my-crontab
CMD ["cron", "-f"]

RUN apt-get update && \
apt-get install -y cron && \
chmod +x /my-script && \
(crontab -l 2>/dev/null; echo "*/10 * * * * /my-script") | crontab -
要构建并运行此示例,您将:

-
docker build --tag = test。
-
docker run -it --rm test

docker rmi test
docker build --tag=test .
docker run -it --rm test
- and for cleanup afterwards
docker rmi test
