Ember CLI 构建已终止

Question

我在启动时在 docker 容器中构建 Ember CLI 应用程序。构建失败，没有错误消息，它只是说 killed:

root@fstaging:/frontend/source# node_modules/ember-cli/bin/ember build -prod                   
version: 1.13.15
Could not find watchman, falling back to NodeWatcher for file system events.
Visit http://www.ember-cli.com/user-guide/#watchman for more info.
Buildingember-auto-register-helpers is not required for Ember 2.0.0 and later please remove from your `package.json`.
Building.DEPRECATION: The `bind-attr` helper ('app/templates/components/file-selector.hbs' @ L1:C7) is deprecated in favor of HTMLBars-style bound attributes.
        at isBindAttrModifier (/app/source/bower_components/ember/ember-template-compiler.js:11751:34)
Killed

相同的 docker 图像在另一个环境中成功启动，但没有硬件限制。 Ember CLI 是否对构建过程有硬编码的硬件限制？ RAM限制为128m，交换为2g。

Ember CLI 可能没有足够的内存来执行它需要的操作。您是正确的，由于 OOM 情况，该进程正在被终止。如果您登录到主机并查看 dmesg 输出，您可能会看到如下内容：

可能值得使用 https://github.com/google/cadvisor 之类的方法来分析容器，以找出它可能需要的最大内存类型。
