amazon aws wrapper

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

Install

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

Example

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
    });
});
