我正在使用Heroku Pipeline。我的暂存应用是我的审阅应用的父应用，因此环境变量相同。
我的登台应用程序每次都构建，没有问题。但是，我所有的评论应用程序都无法构建。问题似乎是评论应用程序缺少加密密钥。
我已经运行了heroku config:set RAILS_MASTER_KEY=##### -a my-app-staging-pr-99来设置评论应用程序的主密钥，但我仍然收到相同的构建错误。
注意：- 我正在使用带有凭据的 Rails 5.2.3- 我的生产中有config.read_encrypted_secrets = true.rb- 我的凭据中设置了">secret_key_base.yml

几周来我一直在尝试解决此问题，但一直无法弄清楚。我是新手，所以如果我在这里错过了一些明显的东西，我深表歉意。
一种方法是将
RAILS_MASTER_KEY添加到环境变量 您的暂存应用。然后在您的评论应用中，您可以从 暂存应用。
通过执行生成密钥
rake secret
在您的项目目录中
可以使用以下命令在暂存应用上设置配置变量
heroku config:set RAILS_MASTER_KEY=<KEY GENERATED BY rake secret> -a my-app-staging
现在，在您的 app.json 中，您可以添加
"env": {
"RAILS_MASTER_KEY": {
"required": true
}
这样，每个新创建的评论应用程序都将从暂存应用程序中获取其RAILS_MASTER_KEY。
希望对您有所帮助。
