한줄 요약

  • 생각보다 쉽지 않기 때문에 Windows로 하기 보다는 WSL2로 하는 것을 권한다.
    • 이 부분은 추후 업데이트 할 예정이다.

Windows에 EB CLI 설치

C:\WINDOWS\system32>python --version
Python 3.7.4

C:\WINDOWS\system32>pip --version
pip 19.0.3 from c:\users\human\appdata\local\programs\python\python37-32\lib\site-packages\pip (python 3.7)
  • pip을 이용하여 EB CLI를 설치한다.
C:\Windows\System32> pip install awsebcli --upgrade --user
  • 환경변수를 설정한다.
    • Python 3.7 버전으로 설치 했다면, 아래 코드를 환경변수에 추가한다.
%USERPROFILE%\AppData\roaming\Python\Python37\scripts

  • 그리고 시스템 환경에서 eb –version이 나오는지 확인한다.
C:\WINDOWS\system32>eb --version
EB CLI 3.20.3 (Python 3.7.4)

Python 가상환경 설정 및 Django 설치

  • 이름이 eb-virt인 가상환경을 만들고 활성화한다.
$ pip install virtualenv
$ virtualenv eb-virt
$ source eb-virt/Scripts/activate
(eb-virt) $
  • Django를 설치한다.
(eb-virt) $ pip install django
(eb-virt) $ pip freeze
asgiref==3.5.2
Django==3.2.13
pytz==2022.1
sqlparse==0.4.2
typing_extensions==4.2.0

Django 프로젝트 생성

  • Django 프로젝트를 생성한다. 가상환경에 접속을 진행한다.
(eb-virt) $ django-admin startproject ebdjango
(eb-virt) $ cd ebdjango
(eb-virt) ~/ebdjango$ python manage.py runserver
Watching for file changes with StatReloader

You have 18 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.

Elastic Beanstalk에 맞게 Django App 구성

  • 이제 Elastic Beanstalk에 배포하도록 이를 구성한다.
  • 기본적으로 Elastic Beanstalk는 application.py 파일을 찾아 애플리케이션을 시작한다.
  • pip freeze를 실행한 다음 requirements.txt 파일에 출력 저장한다.
(eb-virt) ~/ebdjango$ pip freeze > requirements.txt
  • .ebextensions이라는 디렉터리를 생성한다.
(eb-virt) ~/ebdjango$ mkdir .ebextensions
  • .ebextensions이라는 디렉터리 내에서 다음 텍스트가 있는 django.config 구성 파일을 추가한다.
option_settings:
  aws:elasticbeanstalk:container:python:
    WSGIPath: ebdjango.wsgi:application
  • 여기까지 했으면, 가상 환경을 비활성화한다.
$ deactivate

$ tree -a -L 2

Elastic Beanstalk 프로젝트 구성

  • 먼저 eb init 명령으로 CLI Repo를 초기화한다.
  • eb init을 지정하면 순차적으로 입력하면 된다.

  • 환경을 만들고 해당 환경에 애플리케이션을 배포 준비를 한다.
    • Elastic Beanstalk 환경을 생성할 때, 약 3-5분가량 소요 됨.
~/ebdjango$ eb create django-env
  • 실제 환경 생성 프로세스가 완료되었는지 확인한다.

Django 배포

  • 사용자 환경의 도메이 이름은 CNAME에 정의되어 있다.
  • 이제 settings.py를 열고, 이를 ALLOWED_HOSTS에 추가한다.
    • 각자의 CNAME을 등록하면 된다.
ALLOWED_HOSTS = ['eb-django-app-dev.elasticbeanstalk.com']
  • 파일을 저장한 후 배포를 진행한다.
~/ebdjango$ eb deploy

  • 정상적으로 배포가 되었다면 아래와 같이 접속이 되는 것을 확인할 수 있다.

사이트 관리자 생성

  • 우선 로컬 데이터베이스를 초기화해야 한다. +

  • 이번에는 관리자를 생성한다.

This password is too common.
Bypass password validation and create user anyway? 
[y/N]: y
Superuser created successfully.
  • 정적 파일을 저장할 위치를 Django에 알리려면 STATIC_ROOT에서 settings.py를 정의한다.
import os 
..

STATIC_URL = '/static/'
STATIC_ROOT = "static"
  • 그리고 또한 django.config 파일을 아래와 같이 수정한다.
option_settings:
  aws:elasticbeanstalk:container:python:
    WSGIPath: ebdjango.wsgi:application
  aws:elasticbeanstalk:environment:proxy:staticfiles:
    /static: static
  • 각 static 파일들은 각자 다른 경로에 나눠져 있는다. 이를 하나로 모으도록 한다.
(eb-virt) ~/ebdjango$ python manage.py collectstatic
  • 파일까지 다 모았다면 이제 배포를 진행하도록 한다.
    • 배포 시에는 deactivate 명령어 실행하여 가상환경에서 나와야 한다.
~/ebdjango$ eb deploy
  • 실제 Admin에도 잘 들어가는지 확인한다.
