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 image FROM python:3.8-slim # Set the working directory in the container WORKDIR /app # Copy the current directory contents into the container at /app ADD . /app # Install any needed packages specified in requirements.txt RUN pip install --no-cache-dir -r requirements.txt # Make port 80 available to the world outside this container EXPOSE 80 # Define environment variable ENV NAME World # Run app.py when the container launches CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "80"] fastapi uvicorn from fastapi import FastAPI app = 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。
