问题 I recently changed my lambda functions to use the new aws Lambda Layer functionality, to share all the node_modules folder. I created the zip with the following structure: nodejs/node_modules/<libraries, like 'async' and others..> nodejs/package.json I also linked the lambda function to the layer, and it succeed (checked both in the CLI and in the web console), see output below.. but anyway, always the lambda function fails on the require: in lambda: require('async') output: "errorMessage":

问题 How can invoke a AWS Lambda regularly, specifically every 1 minute ? The current functionality allows Lambdas to be setup with 5 minute trigger but I am looking for a much lesser time interval . I thought of running the Lambda for ever but looks like that can't be done since the Maximum execution duration per request 300 seconds 回答1: [Removed previous answer and update] Now, AWS Lambda provides a per minute frequency CloudWatch Events - Schedule as a trigger option. 回答2: There was a session

问题 I describe existing AWS Lambda function in CloudFormation template and I face with the next issue. In our Lambda we configured few test events which helps us to verify some usecases (I mean functionality from the screenshot below). But I don't see any abilities to add these test events to the CloudFormation template. AWS documentation don't help me with that. Is that possible at all or are there any workarounds how to export and import Lambda function test events? 回答1: Lambda test

问题 How would one run aws lambda locally (java) for testing.

I have tried putting the parameters directly into the dynamoDB.get call as well as googling for a while and trying to find someone with a similar issue. I found some that were close, but none that talk about a single function firing multiple times while using the built in test button. I have also tried making

问题 I have an AWS Lambda function that is invoked when an instance gets terminated and this the message is stored in Amazon CloudWatch Logs. I want to extract and filter these log messages to get a particular ID. How can I extract the logs and filter it using Python? 回答1: The easiest method might be to create a rule in Amazon CloudWatch Events that triggers an AWS Lambda function. The function automatically passes information relating to the instance that was terminated. You can write the Lambda
