问题:Dockerize Flutter Web 项目

我正在尝试对我的颤振网络项目进行码头化。并且创建了一个图像并且该站点完美运行,只是找不到我的网站的图片并且没有显示,我不知道为什么。它给了我这个错误:

# Record the exposed port
EXPOSE 5000

# make server startup script executable and start the web server
RUN ["chmod", "+x", "/app/server/server.sh"]

ENTRYPOINT [ "/app/server/server.sh"]

这是 server.sh 文件:

#!/bin/bash

# Set the port
PORT=5000

# Stop any program currently running on the set port
echo 'preparing port' $PORT '...'
fuser -k 5000/tcp

# switch directories
cd build/web/

# Start the server
echo 'Server starting on port' $PORT '...'
python3 -m http.server $PORT

解答

所以这就是事情。我认为他的代码存在一些问题。正如我昨天试图用他的代码构建的,但事情并没有按应有的方式工作。我花了 2 个小时处理他的代码,其中 50% 用于构建图像,但从未完成。没问题我试图修改一些东西,我在 GitHubhttps://github.com/ash-0001/fludino.git上与你分享一些代码。只是继续学习和分享。 好就是形象。

最终图像如下所示:

您必须使用两个命令来初始化它:在此之前使用您的 cmd 进入目录

1. 搬运工构建 -t Flut 。

2. 搬运工运行 -i -p 808:4040 -td Flut
