aws-lambda

问题 I'm at my wits end. I'm trying to install aws-sam-cli so that I can test AWS Lambda functions locally. I've followed all the tutorials I can find but I'm stuck. I've installed docker and python 3.7 onto my local machine but when I try to install aws-sam-cli using: pip install aws-sam-cli I get the following error: Could not find a version that satisfies the requirement pypiwin32==220; sys_platform == "win32" and python_version >= "3.6" (from docker>=3.3.0->aws-sam-cli) (from versions: 219,

问题 I have a AWS Lambda function which need to talk to an external REST API. The external API needs a session token with every request. I generate session token using client id and secret and then i use the session token with further requests to the external REST API.

I think this is not the best way. what is the best / recommended way ? 回答1: The approach you are

问题 I have provisioned an AWS API Gateway and created a Lambda function to connect to an external REST API. The API Gateway & Lambda is not in a VPC so the egress IP address is random. The challenge I have is the external REST API is behind a firewall, which requires the IP address or subnet of the Lambda to be whitelisted. I have looked at the AWS IP Address page (below), however there is no explicit mention of either API Gateway or Lambda. https://docs.aws.amazon.com/general/latest/gr/aws-ip

问题 I am experimenting with a blue/green deployment setup for lambdas using terraform and lambda aliases. I am trying to automatically retrieve the previously deployed version of the lambda by using the aws_lambda_function data source and using the value inside the routing_config => additional_version_weights. This would allow me to set up a traffic split between the previously deployed version and the version that has just been deployed. However, I have run into 2 errors I don't quite understand

问题 Is there any possibility of running a Perl program from lambda functions in Amazon Web Services ? 回答1: You can run essentially anything in Lambda as long as it is binary-compatible with the Lambda runtime environment and can fit into a deployment package. But you have to wrap it in a function written in one of the supported languages. This is surprisingly more effective and efficient than you might expect, particularly if you can write your code in the other language so that it can be spawned
