角度AOT编译策略

Question

我在过渡和生产版本中使用以下配置，

{
    "fileReplacements": [
    {
        "replace": "src/environments/environment.ts",
        "with": "src/environments/environment.qa.ts"
    }
    ],
    "optimization": true,
    "outputHashing": "all",
    "sourceMap": false,
    "extractCss": true,
    "namedChunks": false,
    "aot": true,
    "extractLicenses": true,
    "vendorChunk": false,
    "buildOptimizer": true,
    "budgets": [
    {
        "type": "initial",
        "maximumWarning": "2mb",
        "maximumError": "5mb"
    },
    {
        "type": "anyComponentStyle",
        "maximumWarning": "6kb",
        "maximumError": "10kb"
    }
    ]
}

当前，我正在做ng build --configuration qa作为docker构建步骤的一部分。

这最初会因内存不足问题而失败，我已通过将命令更新为来解决此问题，

node --max_old_space_size=8192 ./node_modules/@angular/cli/bin/ng build --configuration qa

为什么仅在Docker上下文中构建会耗尽内存？
