Just wraps commandline calls to aws with some predefined filters for amis, instances, public and private dns data.

You have to install all the amazon tools you'd like to use (eg. ec2, elb, autoscaling tools).

The environment variables for the tools have to be configured. Something like:

EC2_HOME=/opt/ec2-api-tools EC2_AMITOOL_HOME=/opt/ec2-ami-tools AWS_AUTO_SCALING_HOME=/opt/AutoScaling AWS_CLOUDWATCH_HOME=/opt/CloudWatch AWS_ELB_HOME=/opt/ElasticLoadBalancing EC2_PRIVATE_KEY="your-aws-private-key" EC2_CERT="your-aws-certificate" EC2_ACCESS_KEY="your-aws-access-key" EC2_SECRET_KEY="your-aws-secret" AWS_CREDENTIAL_FILE=your-credential-file EC2_REGION=eu-west-1 EC2_KEYPAIR_EU_WEST_1=your-aws-key-pair 

Then just install the module with npm.

npm install aws 

var aws = require('aws'); aws.setRegion('eu-west-1'); aws.init(['ec2', 'aws_elb', 'aws_auto_scaling'], function(apis){apis.ec2.describe_instances.public_dns(function(instances){sys.puts(sys.inspect(instances)); // lists all public dns of your ec2 instances })});
