第一次使用 Docker(版本 19.03.5)并尝试本教程
我被困在步骤 2.3.4 运行图像
当我去http://localhost:8888我看到
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
我更新Dockerfile到这个以匹配我的目录:
# our base image
FROM alpine:3.5
# Install python and pip
RUN apk add --update py2-pip
# install Python modules needed by the Python app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
# copy files required for the app to run
COPY app.py .
COPY templates/index.html templates
# tell the port number the container should expose
EXPOSE 5000
# run the application
CMD ["python", "app.py"]
在我的命令行上,
C:\Users\user\docker\flask-app>docker run -p 8888:5000 --name flask-app 11111111/flask-app
* Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
当我访问提示时看到的页面时
172.17.0.1 - - [05/Jan/2020 07:14:34] "GET / HTTP/1.1" 500 -
我的 app.py 中有这个
from flask import Flask, render_template
import random
app = Flask(__name__)
# list of cat images
images = [

我不知道为什么我的页面没有加载。任何帮助,将不胜感激。
注意:我安装了 WAMP,这可能会发生冲突,但不确定是否是这种情况和/或如何修复它。
