Dockerfile for a simple Flask Project
To package our project into a Docker container, we need an additional command: WORKDIR
.
FROM python:3.9-slim
# Set the working directory inside the container
WORKDIR /flask-app
COPY . .
RUN pip3 install -r requirements.txt
# Set the command to run the Flask application
CMD [ "python3", "-m" , "flask", "run", "--host=0.0.0.0"]
The WORKDIR
command in Docker sets the working directory for any subsequent instructions in the Dockerfile. In your case, WORKDIR /flask-app
sets /flask-app
as the working directory.
This means that any further instructions (such as COPY
, RUN
, CMD
, etc.) will be executed in the context of this directory. For example, if you execute COPY app.py /flask-app
, the file app.py
will be copied into the /flask-app
directory inside the container.
This is useful for organizing your project within the container and ensuring clarity about where operations are taking place within the Docker image.
