[Cloud] 배포 - NCP : 로컬 서버에서 DB 띄우기: NoSQL

NoSQL

NoSQL 중 하나인 MongoDB 를 이용하여 DB 를 구성해보자.

새로운 blog 앱을 생성한다.

python3 manage.py startapp blog

pip install pymongo

pip freeze | grep pymongo >> requirements.txt

views.py

from pymongo import MongoClient

client = MongoClient()
db = client.likelion    

def create_blog() -> bool:
    blog = {
        "title" : "My first blog",
        "content" : "This is my first blog",
        "author" : "lion",
    }
    try:
        db.blogs.insert_one(blog)
        return True
    except Exception as e:
        print(e)
        return False    

def update_blog():
    pass

def delete_blog():
    pass

blog app - urls.py

from django.urls import path
from . import views

urlpatterns= [
    path('', views.create_blog, name='blog-create'),
]

project - urls.py

...
from blog.urls import urlpatterns as blog_urls

urlpatterns = [
    path('admin/', admin.site.urls),
    path('blog/', include(blog_urls)),
]

project - settings.py

## Created Apps
INSTALLED_APPS += [
    'forumapp',
    'blog',
]

mongoDB 이미지 pull and run

docker pull mongo

docker run --name mongo -p 27017:27017 -d mongo

docker volume create mongo_data

docker-compose.yml

...
mongo:
    container_name: mongo
    image: mongo:lagest
    ports:
      - 27017:27017
    volumes:
      - mongo_data:/data/db

volumes:
  staticfiles:
  postgres_data:
  mongo_data:

실행

docker-compose -f ../docker-compose.yml up --build -d

URL 중 ‘blog’ 를 pymongo 를 사용하는 blog app 에서 create_blog 로 연결해 두었기 때문에 브라우저에서 blog 로 접속하게 되면 에러는 발생하지만 값이 들어가게 된다.

Mongo 컨테이너 접속 후 쉘 접속

docker exec -it mongo /bin/bash

mongosh
