ember.js - Ember CLI构建被杀死

Question

启动时，我在Docker容器中构建了Ember CLI应用程序。构建失败，没有错误消息，它只显示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镜像可在另一个环境中成功启动，但没有硬件限制。 Ember CLI对构建过程是否具有硬编码的硬件约束？ RAM限制为128m，并交换为2g。

Ember CLI可能没有足够的内存来执行所需的操作。您的说法是正确的，由于OOM情况，该进程已被终止。如果登录到主机并查看dmesg输出，则可能会看到类似以下内容的内容:

可能值得使用https://github.com/google/cadvisor之类的文件来分析容器，以找出其可能需要的最大内存量。
