我一直在尝试对Sails 1.0.2应用进行docker化，以便能够通过docker-compose在本地运行，但是它似乎无法以任何方式连接到PostgreSQL服务器。
此外，我想我可能会缺少一些有关如何使用Sails创建数据库的概念。我尝试过两种模型的“安全”行为（用于手动迁移），“更改”和“丢弃”。
在运行安全模式时，我尝试在容器中的单独任务中使用sails-migrations db:create或sails-migrations migrate来检查是否有必要设置任何数据库，即使我仍然有仅由脚手架生成的User.js模型。
它们似乎都不起作用。另一方面，Docker数据库本身看起来就像是创建的。任何帮助将不胜感激，在此先感谢。

尽管由Docker创建的数据库似乎很好，但我还是得到 ECONNREFUSED （可能是在我尝试使用Docker DB或DB连接的参数来尝试使其正常工作时），或者是以下内容错误（成功连接到数据库时）：

您的COPY将数据库主机引用为dpkg -i，从组合文件运行时，它应该是Docker服务datastores.js的名称。 localhost中的迁移部分将主机引用为postgres
