关于将网络核心应用程序部署到Heroku服务器

分类: 技术问答 • 2022-05-08 22:01:24
问题描述：

我正在尝试使用docker将.net核心WEB API部署到Heroku服务器.我构建并发布了我的应用程序，构建了我的docker映像，然后将其部署到Heroku服务器.我已经运行了以下命令:

I am trying to deploy .net core WEB API to Heroku servers with docker. I build and publish my App, I build my docker image and after I deploy to Heroku servers. I have run the following commands:

  1. heroku登录
  2. heroku container:登录
  3. dotnet恢复
  4. dotnet发布-c版本
  5. docker build -t pdx-ys-backend.(在docker文件文件夹"bin \ Release \ netcoreapp2.2 \ publish"中)
  6. docker标记pdx-ys-backend Registry.heroku.com/pdx-ys-backend/web
  7. docker push Registry.heroku.com/pdx-ys-backend/web
  8. heroku容器:发布网络--app pdx-ys-backend

我的docker文件是:

My docker File is:

WORKDIR /app
COPY . .

            WebHost.CreateDefaultBuilder(args)

平台向我显示以下错误

The platform shows me the following error

这是Heroku的日志:

我尝试使用各种docker文件，将端口更改为8080，但我在启动时一直在寻找问题，但没有找到解决方案.

I have tried with various docker files, changing the port to 8080, and I was looking for issues in my startup but I didn't find the solution.

https://devcenter.heroku.com/articles/setting-the-http-port-for-java-applications

这是为Java应用程序编写的，但它适用于Heroku上托管的任何Web应用程序.当您运行Web Worker时，必须将端口绑定到环境变量 $ PORT .您无法指定自定义端口.

this is written for java application but it applies to any web application hosted on Heroku. When you are running a web worker you have to bind the port to the environment variable $PORT. You cannot specify a custom port.

绑定到正确的端口后，这些错误应消失:

Once you bound to the proper port these error should vanish:

Unhandled Exception: System.Net.Sockets.SocketException: Permission denied

然后您的应用程序可能会运行，或者您可能遇到其他错误.如果您以后遇到其他问题，请创建一个新问题.

Your application might then work or you might be experiencing different errors. If you are experiencing later a different issue please create a new question.
