Docker Container Running 但它拋出錯誤 Template does not Exist

Question

嗨，我是 Docker 的新手，我創建了一個 Django 應用程序，它在本地機器上運行良好但是當我嘗試在 docker 容器中運行時它運行正常但是當我發送請求時發現錯誤模板不存在

 Dockerfile
#syntax=docker/dockerfile:1
#FROM ubuntu:latest
FROM ubuntu:latest
FROM python:3.8-slim-buster
WORKDIR /app
#COPY requirements.txt requirements.txt

#RUN pip3 install -r requirements.txt
#
#CMD python . /manage.py runserver 0.0.0.0:8000"""
# pull the official base image

# set work directory


# set environment variables

#RUN pip3 install virtualenv

COPY requirements.txt requirements.txt

RUN pip3 install -r requirements.txt
# copy project
COPY . /app

EXPOSE 8000

CMD ["python3", "manage.py", "runserver", "0.0.0.0:8000"]
# 

我的 Docker 文件看起來像那樣

docker-cpmpose.yml
version: "3"
   
services:
   web:
       build: .
       command: python3 manage.py runserver 0.0.0.0:8000
       ports:
           - 8000:8000

我的模板文件夾位於 Blog app templates/blog/templtes.html

當我運行#docker-compose up 然后我的圖像服務器啟動但是然后我從我的瀏覽器發送請求我得到錯誤頁面

有人可以幫我解決這個錯誤

Answer 1

根據您的 Dockerfile，您必須將 django 項目從一個文件夾復制到另一個文件夾，並且您沒有設置 workdir。

而不是這個：

COPY . /app  #here only you copied but didn't set where to copy

試試這樣：

COPY ./app /app    #here copied Django project from one folder to another.
WORKDIR /app

注意：不要忘記重新構建此 Dockerfile。
