PermissionError: [WinError 5] Access Denied: [4776] Failed to execute script docker-compose when running docker-compose up

Question

我构建了一个测试应用程序以更好地理解 FastAPI 和 sqlalchemy 的概念我想成为能够提供 docker-compose.yml 的应用程序，它可以用于运行我的解决方案，只需做 docker-compose up

但是我得到了

Building al_test

[4776] Failed to execute script docker-compose

我的docker文件

FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7

COPY ./requirements.txt /requirements.txt
RUN pip install -r /requirements.txt 

COPY . /app

WORKDIR /app
ADD . /app

ENV DATABASE_URL="postgres://superuser:superuser@localhost:5433/al-test-3" 

EXPOSE 8000

CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8000"]

和docker-compose.yml

version: '3.8'
services:
  al_test:
    build: /
    ports:
     - 5001:80
  postgresql:

TL;DR

我认为有问题：

    build: /

要以本地文件夹作为上下文进行构建，您应该说

    build: ./

究竟发生了什么？

话虽如此，您的项目是如何构建的？你的 Dockerfile 在哪里？是吗

app
    - some.py
Dockerfile
requirement.txt
docker-compose.yaml

从您的 docker-compose.yml 的角度来看，./ 是它所在的文件夹。在 Unix 文件系统中，/ 代表文件系统的 根目录;你会怎么称呼 C:\.

构建时

我不确定 docker 是如何集成到 Windows 中的，但是 / 可能被翻译成某个地方您的 docker 恶魔没有阅读权限，在您编译期间引发此 PermissionError。

在运行时间

您在尝试将各种文件夹装载到您的容器中时可能会遇到类似的权限问题。这是修复（当它发生时）
