GitHub自动化部署(CD) asp.net core 5.0 项目(免费空间)

本文主要是介绍GitHub自动化部署(CD) asp.net core 5.0 项目(免费空间)，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

这里我简单介绍一下使用Github自动化部署自己项目到Heroku云服务器上,Heroku竟然是一个很非常老牌的云平台服务商,竟然还没听说过，网上一查2010被Salesforce收购,网上有很多关于asp.net core 使用（Docker和CircleCI）部署的文章，都比较旧了，也比较麻烦，必须先配置Dockerfile再Build成功镜像再部署，但现在都是2021年了.net core又那么火什么项目都再讲CI/CD，没有理由不支持直接部署的,所以经过自己的尝试成功了,那就写一篇blog和大家分享一下。让我们开始吧。

Heroku 注册账号

Heroku: Cloud Application Platform
免费注册,这里我就不详细说明了,邮箱不要用国内厂商的就行

新建 Application

Click [New] button create new app

Input App name and Click [Create app]

配置 Application Deploy/Settings

Deployment method select GitHub(Connect to GitHub)
Search project name

Click [Connect]
你可以选择 [Enable Automatic Deploys] 如果不勾选 [wait for CI to pass before deploy] 默认 main分支一有Push或是Merge PR就会自动部署, [wait for CI to pass before deploy]的意思就是先运行集成测试脚本通过了在部署。

这是如果想 Click [Deploy Branch],是无法部署成功，会提示错误，原因就是.net core 需要.net framework编译

切换到[Settings], Click [Add buildpack]

输入: [https://github.com/jincod/dotnetcore-buildpack]

现在你再次Click [Deploy Branch] 部署就可以完成了

可以访问你的网站了[http://razorapp.herokuapp.com/authorization/profile]

回到我们Github项目中你就会看到你配置自动部署的application

在这个过程中还遇到一个错误

System.IO.DirectoryNotFoundException: /app/heroku_output/Files/

没有找Files这个目录
对应这段代码

 app.UseStaticFiles(new StaticFileOptions
            {
                FileProvider = new PhysicalFileProvider(Path.Combine(Directory.GetCurrentDirectory(), @"Files")),
                RequestPath = new PathString("/Files")
            });

我的解决方案是
在启动时新建这个目录

最后

Keeping Coding, Enjoy Coding.
