dockerfile 在 github 中運行，有找不到模塊的問題

Question

我很確定如果我在本地使用當前的 docker 文件進行構建，我可以運行圖像

# pull the official docker image
FROM python:3.9.4-slim

# install requirements
COPY backend/copium_api/requirements.txt .
RUN pip install -r requirements.txt

# copy project
COPY . .

EXPOSE 8715


CMD ["python", "-m", "server"]

但當我在 Github 行動中這樣做時，我看到了這個問題

無法使用此錯誤啟動任何內容

/usr/local/bin/python: No module named server

我能知道我應該如何寫這個 dockerfile 才能工作嗎？

github行動

name: Docker Image CI

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:

  build:

    runs-on: ubuntu-latest
    

    steps:
    - name: Login to GitHub Container Registry
      uses: docker/login-action@v1
      with:
        registry: ghcr.io
        username: ${{ github.actor }}
        password: ${{ secrets.DOCKER_TOKEN }}
    
    
    - uses: actions/checkout@v3
    - name: Build the Docker image
      run: |
        docker build . --file backend/copium_api/Dockerfile --tag app:latest
        docker run app:latest
        docker push app:latest

在服務器目錄中我的init .py 文件下

from server.api.router import api_router
from common.constant import API_PREFIX, API_TITLE, API_DOCS, OPENAPI_URL
from fastapi import FastAPI
from fastapi.middleware.cors import CORSMiddleware

app = FastAPI(
    title = API_TITLE,
    docs_url = API_DOCS,
    openapi_url = OPENAPI_URL,
)

app.add_middleware(
    CORSMiddleware,
    allow_origins=["*"],
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)

app.include_router(api_router, prefix=API_PREFIX)

只是一個普通的 fastapi 調用

您正在使用--file backend/copium_api/Dockerfile但所有構建上下文都是相對於. 這意味着您的文件未按預期復制。
您有 3 個選擇：

1. cd進入構建前的目錄（並將COPY backend/copium_api/requirements.txt.更改為COPY requirements.txt. ）
2. 將您的第二個COPY語句更改為COPY backend/copium_api/*.
3. 將您的入口點更改為python -m backend/copium_api/server

建議的更改：
Dockerfile :

# pull the official docker image
FROM python:3.9.4-slim

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

# copy project
COPY . .

EXPOSE 8715


CMD ["python", "-m", "server"]
