Question

您好我正在数字海洋上玩Dokku作为Heroku的替代品。我已经阅读过Digital Ocean和其他博客的至少15个指南。除非我第一次运行rails迁移，否则一切看起来都非常简单。

我收到以下错误...

我已将postgresql数据库与我的Dokku应用程序相关联。我唯一能想到的是它与我的Dokku配置或与我的database.yml重叠Dokku配置设置有关。我似乎无法弄明白。

我的用于制作的database.yml文件是：

production:
  url: <%= ENV['DATABASE_URL'] %>

我的应用程序的dokku配置是：

DATABASE_URL:      postgres://root:password:/db
NO_VHOST:          1
rails_env:         production

我可以确认config中的密码与db：migrate错误中的密码相同。这也与我在Dokku应用程序export中的内容相同，我通过从服务器运行这一系列命令找到了...

docker run -i -t dokku/app_name /bin/bash
export HOME=/app
for file in /app/.profile.d/*; do source $file; done
hash -r
export

任何人都能够获得额外的光线吗？

这可能是dokku-pg-plugin的最新问题，因为我能够使用较旧版本的dokku-pg-plugin创建数据库/使用数据库连接应用程序。< / p>

我向项目团队提出了一个问题，他可以提出建议：https://github.com/Kloadut/dokku-pg-plugin/issues/69。

Answer 2

我认为数据库URL不正确。它看起来应该像postgres://root:password@localhost/db

Dokku + Rails + Postgresql错误 - URI :: InvalidURIError：方案postgres不接受注册表部分：root
