Create a new Dockerfile in the root directory of your Python project. The Dockerfile name must be this or an error will be reported.

FROM python:3.6.8-slim-stretch WORKDIR /usr/src/app COPY requirements.txt./ RUN PIP install -- no-cache-dir-r requirements.txt COPY . . ENTRYPOINT ["python"] CMD ["./run.py"]Copy the code

3. Create a mirror

To create a mirror, run the following command:

Docker build-t python-project:1.0.Copy the code

Note the last “. Can’t omit, “. Represents the current directory

4. Run the image

To run the image, run the following command:

Docker run --rm -p 55:5000 --name pyProject python-project:1.0Copy the code

The parameters in this command have the following meanings

• – rm: indicates that when the cli window is closed, the process running the image will be closed at the same time.
• -p: used to set port mapping, that is, to map the port of the host computer to the port in the Docker container. How to encapsulate a Web service, so port mapping must be set;
• – name: set an alias for the running image for later invocation

In addition, parameters that may be used frequently include:

• -e: adds environment variables for the mirror
• -d: Keeps the Web running in the background
