要在FastAPI中实现Docker容器化,可以按照以下步骤操作:
# Use an official Python runtime as a parent imageFROM python:3.8-slim# Set the working directory in the containerWORKDIR /app# Copy the current directory contents into the container at /appADD . /app# Install any needed packages specified in requirements.txtRUN pip install --no-cache-dir -r requirements.txt# Make port 80 available to the world outside this containerEXPOSE 80# Define environment variableENV NAME World# Run app.py when the container launchesCMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "80"]
fastapiuvicorn
from fastapi import FastAPIapp = FastAPI()@app.get("/")async def read_root():return {"Hello": "World"}
在包含Dockerfile文件的目录下执行以下命令来构建Docker镜像:
docker build -t fastapi-app .
执行以下命令来运行Docker容器:
docker run -d --name fastapi-container -p 80:80 fastapi-app
现在,您的FastAPI应用程序已经容器化,并通过Docker容器运行。您可以通过访问 http://localhost 来访问应用程序。
