为什么在推送到 openshift 后重置 mongodb

Question

我正在将使用sails.js 编写的应用程序部署到openshift 上。

它可以正常工作，但是当我提交新内容时。

然后它将再次构建并清理我在 mongodb 中的所有数据。

所以我想知道有什么原因吗？

对不起，我是 openshift 的新手

1. 在停止/启动 MongoDB 墨盒后是否会正常清理 mongodb？

2. 如何将数据保留在 mongodb 中？停止时需要保存，启动时需要恢复吗？

3. 我很好奇它是如何自动构建和重启墨盒的？ 我正在使用 node.js Cartidge 并查看了 action_hooks 但没有明显的提示。只是想知道它如何以及为什么会触发 nodejs 和 mongodb 墨盒重启？

谢谢

这是我的日志消息

Answer 1

它通常不应该清除您的数据。您的应用程序可能设置不正确。您可能需要检查所有设置是否正确。
