通过AWS CLI在AWS Lambda中向函数添加或删除Layer的方法在AWS CLI中，如何向AWS Lambda的函数中添加或删除Layer
因为在AWS CLI中添加或删除Lambda函数的Layer的方法不太清楚，所以写下了以下备忘录。
前提 (Qian Ti)
-
- AWSアカウントがある
-
- AWS CLIが利用可能
-
- 検証できるLambda関数がある

创建Lambda Layer
创建用于验证的Layer。由于此次不在函数内引用，所以在含有//的文件中创建Layer。空文件将不起作用。
使用AWS CLI，可以使用aws lambda publish-layer-version命令来创建。
> echo '//' layer.js
> zip layer.zip layer.js
> aws lambda publish-layer-version \
--layer-name test-layer-1 \
--zip-file fileb://layer.zip \
--compatible-runtimes nodejs8.10

}
在函数中添加Lambda层
假设存在用于验证的函数”use-lambda-layer”。
如果要指定Layer，请指定包含版本的LayerVersionArn，该LayerVersionArn可以从上述ARN中获取。如果要添加多个Layer，请使用空格进行分隔指定。

从函数中删除Lambda Layer
不是删除Layer，而是重新指定要使用的Layer。
要全部删除，请指定–layers []，即空数组。这可能会令人困惑。

AWS Lambda层 – AWS Lambda
https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html
亚马逊云服务的AWS Lambda层是一种功能，用于将共享代码、库和资源从函数中分离出来，以便在多个Lambda函数中共享。Layers允许您在函数之间共享和管理通用功能，提高开发速度和灵活性。详细信息可参考上述链接。
发布层版本 — AWS CLI 1.16.182 命令参考
