[PYTHON] Initial setting of environment using Docker-compose + Django + MySQL + Nginx + uwsgi

Overview

• I needed to create an environment that uses the title, so make a note of it.
• In addition, Japanese localization etc.

environment

• Docker + Docker-compose must be available.
• Python3.6
• Django 3.1 (latest)

procedure

Directory structure

• Create directories and files with the following configuration.

./WORKDIR
    |--- docker-compose.yml   # Docker-compose body
    |---.gitignore            #Not applicable to git (I will make it this time, use it when using git)
    |---nginx
         |---nginx.conf       #nginx config file
         |---uwsgi_params     #Parameters for uwsgi
    |---django
         |---Dockerfile       # Dockerfile
         |---requirements.txt #List to install with pip
         |---.env             #Environment variables for django
    |---mysql
         |---.env             #Environment variables for mysql
    |---sql
         |---init.sql         #At DB startup(First time only)Script to flow to

Build

• Create a project.

$ docker-compose run django django-admin.py startproject app .

• The following is created.

• Start-up

$ docker-compose up -d

• DB migration

$ docker-compose exec django ./manage.py makemigrations
$ docker-compose exec django ./manage.py migrate

• Reflect CSS

$ docker-compose exec django ./manage.py collectstatic

Verification

• You can access the following.
  • http://<IP>:8000
  • http://<IP>:8000/admin

reference

• Build a development environment for Django + Nginx + MySQL with Docker
• I am almost indebted to you just by modifying it for myself.
