amazon web services - How can I use environmental variables on AWS Lambda?

I'm writing an application which I want to run as an AWS Lambda function but also adhere to the Twelve-Factor app guidelines. In particular Part III. Config which requires the use of environmental variables for configuration.

However, I cannot find a way to set environmental variables for AWS Lambda instances. Can anyone point me in the right direction?

If it isn't possible to use environmental variables can you please recommend a way to use environmental variables for local development and have them transformed to a valid configuration system that can be accessed using the application code in AWS.

Thanks.

As of November 18, 2016, AWS Lambda supports environment variables.

Environment variables can be specified both using AWS console and AWS CLI. This is how you would create a Lambda with an LD_LIBRARY_PATH environment variable using AWS CLI:

aws lambda create-function 
  --region us-east-1
  --function-name myTestFunction
  --zip-file fileb://path/package.zip
  --role role-arn
  --environment Variables={LD_LIBRARY_PATH=/usr/bin/test/lib64}
  --handler index.handler
  --runtime nodejs4.3
  --profile default
