use-lambda-env

A quick CLI utility to grab environment variables from AWS Lambda functions, and execute shell commands with those environment variables.

Primary expected use-case: running a local development environment with config from a deployed lambda function, while avoiding the need to share secret files among developers. Developers would be expected to simply have AWS CLI access configured (preferrably with short-lived credentials), with Lambda:GetFunction permission to read the lambda function, along with KMS:Decrypt access to the environment variable encryption key used for the function (if applicable).

Example usage

use-lambda-env --region ap-southeast-2 your-function-name node index.js

I'd recommend putting the above in a script in package.json, so that developers don't need to remember it, and so you can update the function name for all developers easily when needed.

You can also just show the environment variables as a JSON blob by doing

use-lambda-env show --region ap-southeast-2 your-function-name
