get-aws-creds from a config file, process.env, or EC2 metadata, in that order.

install

npm install get-aws-creds

use

via config file

var getCreds = require("get-aws-creds");
getCreds(myAwssumCallback, "./path/to/creds/json");

via process.env

Just set AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_REGION.

var getCreds = require("get-aws-creds");
getCreds(myAwssumCallback);

via EC2 instance meta-data

Nothing to do! get-aws-creds uses get-iam-creds to fetch the region and secrets from instance metadata.

var getCreds = require("get-aws-creds");
getCreds(myAwssumCallback);
