Analysis of Docker Containerized Deployment Python Application Process

Simple application deployment

1. Directory structure:

The catalogue of Pythonpro #
test. py # File
The document requirements. txt #
Dockerfile # File

2. Write an Dockerfile file

# Based on mirroring
FROM python:3.6.4
# Create Code Folder Working Directory/code
RUN mkdir /code
# Copy current code file into container/code
COPY . /code
# Install required packages
RUN pip install -r /code/requirements.txt -i https://pypi.douban.com/simple
# Specify the working directory of cmd/code
WORKDIR /code
# Commands to execute when the container starts
CMD ["python","test.py"]

3. Create a container image

docker bulid -t test .

4. Run the container

docker run -it --name test --restart always --privileged=true python-test
--name: Specifies the name of the container as python-test, and test is the image just built.

--restart: The always container always restarts when it exits.

--privileged=true: Permissions required to execute files within the container.

Django Application Containerization

1. The directory structure, which I'm assuming exists at/home/Pythonpro.

The catalogue of Pythonpro #
manage. py # File
The main project # catalogue
The catalogue of apps #
Apparatus-requirements. txt # file
Dockerfile # File
run. sh # File

run. sh script

python /code/manage.py runserver 0.0.0.0:8000

2. Write an Dockerfile file

FROM python:3.6.4
RUN mkdir /code \
&&apt-get update \
&&apt-get -y install freetds-dev \
&&apt-get -y install unixodbc-dev
COPY . /code 
RUN pip install -r /code/requirements.txt -i https://pypi.douban.com/simple
WORKDIR /code
CMD ["/bin/bash","run.sh"]

3. Build a mirror image

docker bulid -t webtest .

4. Run the container

docker run -it -p 6500:8000 -v /home/Pythonpro:/code --name web --restart always --privileged=true webtest

-p: Map port 8000 of container to host 6500

-v: Host directory/home/Pythonprot mapped to container directory/code

--name: Specifies the name of the container as web, the image just built by webtest

--restart: always container always restarts when exiting

--privileged=true: Permissions required to execute files in the container
