Question

我们正在评估向Monorepo的迁移，同时将我们的应用程序托管在Heroku上。我们的源代码树如下所示：

.
├── Gemfile
├── Gemfile.lock
├── backend
│   ├── logger
│   │   ├── Gemfile
│   │   ├── Gemfile.lock
│   │   └── Procfile
│   └── legacy
│   │   ├── Gemfile
│   │   ├── Gemfile.lock
│   │   └── Procfile
└── shared
    ├── gems
    │   └── protos
    └── protos

我们找到了多个与monorepos相关的buildpack，即heroku-buildpack-monorepo和heroku-buildpack-multi-procfile。

在第一种情况下，buildpack用包含应用程序的子目录覆盖部署的根目录。例如，APP_BASE设置为backend/logger。可以，但是我们计划在不同的应用程序之间使用共享的gem，并且覆盖树排除了这种情况：backend/logger将覆盖.，从而删除对shared/gems的访问。

在第二种情况下，启动应用程序之前，需要Procfiles cd到所需目录。我们的Procfile看起来像：

worker: cd backend/logger && bundle exec bin/logger

这是我们首选的前进方式。

问题在于，默认的heroku / ruby buildpack在构建之前不知道cd到应用程序的目录。我在部署时看到的错误消息是：

已安装的gem是在根目录的Gemfile中声明的gem。如果将buildpack安装到release并从那里运行backend/logger，则bundle install任务将成功。

问题是：我们有什么选择？我可能可以创建/扩展一个buildpack，它将复制/移动shared / gems文件夹到在编译和部署阶段仍然可以访问的位置。有一个我不知道的构建包可以支持我们的用例吗？

PS：我调查了https://github.com/Pagedraw/heroku-buildpack-select-subdir，但它在5分钟的测试中未通过。第一次部署没有部署任何东西。

如何将Monorepo部署到Heroku？
