# dockerisation de l'appli avec tout les paramètres

1. [Commande du jour]

docker build -t grabber:latest .


Explanation

A Dockerfile is a text-based document that's used to create a container image. It provides instructions to the image builder on the commands to run, files to copy, startup command, and more.

As an example, the following Dockerfile would produce a ready-to-run Python application:

FROM python:3.13.5
WORKDIR /usr/local/app

# Install the application dependencies
COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt

# Copy in the source code
COPY src ./src
EXPOSE 8080

# Setup an app user so the container doesn't run as the root user
RUN useradd app
USER app

CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8080"]

2. [DOCKER DOCKER DOCKER]

docker build -t grabber-app .
docker build -t grabber:latest .
docker run -dit --name grabber grabber:latest
docker ps
docker exec -ti eb25daZ bash

---------------------------
docker build -t grabber:latest . <- point pas oublier
docker rm --force grabber <supprimer le container du meme nom si test auparavant>
docker ps
docker container ls -a
docker container prune
docker logs grabber
docker run -dit --name grabber grabber 
docker inspect grabber
docker exec -ti grabber bash mettreAdresseIP

compose.yml
services:
 grabber:
  build: .
  depends_on : db
  ports: -"8080:80"
 db:
  image: postgres:18
  environment:
   POSTGRES_USER: gb
   POSTGRES_DB: gbdb
   
3. [Modif dans app.py]
pg_url = (
    f"postgresql+psycopg://"
    f"{os.getenv('POSTGRES_USER')}:"
    f"{os.getenv('POSTGRES_PASSWORD')}"
    f"@db:5432/"
    f"{os.getenv('POSTGRES_DB')}"
)
print(f"URL PGDB: {pg_url}")
engine = create_engine(pg_url)
