Python-创建AWS Lambda部署包 [英] Python - creating aws lambda deployment package

问题描述

我想使用Fabric任务为AWS Lambda的更新代码编写脚本.Boto3 API需要一个以base-64编码的zip文件的字节数组.

I want to script updating code for my AWS Lambda using a Fabric task. Boto3 api expects a byte array of base-64 encoded zip file.

假设我将源代码文件作为输入，创建它的最简单方法是什么?

What would be the simplest way to create it assuming I have the source code files as the input?

推荐答案

使用当前的boto3，请勿将其解压缩，也不要对其进行base64编码.您可以像这样打开并阅读:

With the current boto3, don't unzip it, don't base64 encode it. You can do it with an open and a read like this:

import boto3
c = boto3.client('lambda')
c.create_function({
    'FunctionName': 'your_function',
    'Handler': 'your_handler',
    'Runtime': 'python3.6',
    'Code': {'ZipFile': open('./deploy.zip', 'rb').read()}
})

我使用上面的zip文件快速入门.您还可以将deploy.zip上传到S3存储桶，并将存储桶+键作为字符串传递给代码"字典中的字符串，如"S3Bucket"和"S3Key".

I use the zip file above for getting started quickly. You can also upload the deploy.zip to a S3 bucket and pass the bucket + key as strings in the 'Code' dict as 'S3Bucket' and 'S3Key'.
