Node.js應用突然在本地Docker上失敗

Question

我有一個從克隆一個非常簡單的Node.js應用此 ，唯一增加的是，它連接到一個RDS實例。 它在本地運行良好（帶有boot2docker OSX），當我將其放置在Docker容器中時運行了幾分鍾，然后突然間，該頁面不再呈現，並且服務器收到空響應。 容器仍在運行，但是我在日志中收到一條奇怪的消息。 各種文件如下。

我在這里想念什么？

Docker運行命令 docker run -p 49161:3000 -d <image name>

更新1有趣...似乎容器在大約15分鍾后不再運行。 當我得到Empty response頁面時，它正在運行，但是現在我可以確認容器不再運行。 如果重新執行docker run ，我確實會看到頁面加載簡短，並且容器已打開。

Answer 1

我發布此消息是為了幫助遇到此問題的其他任何人。 本質上，修改我的Dockerfile解決此問題。 顯然，原始容器中的內存過高，導致容器崩潰。 我仍然不清楚為什么會發生這種情況，並且我只使用了大多數原始Dockerfile因為這是我在Docker示例中找到的。

修訂的Dockerfile

FROM node:0.10-onbuild

RUN npm install supervisor -g
RUN npm install pg --save
