Warning: Just a quick prototype. May behaves strange / like an asshole.
SSH into EC2 instances via tags. More or less an exact copy of facebookarchive/ec2-ssh.
$ npm install -g ec2ssh
The module uses the AWS JavaScript SDK internally, so please take a look at: http://docs.aws.amazon.com/AWSJavaScriptSDK/guide/node-configuring.html
By default, ec2ssh will automatically use the shared credentials file (~/.aws/credentials) for configuration when loading.
[default]
output = json
region = eu-west-1
aws_access_key_id = your_aws_access_key_id
aws_secret_access_key = your_aws_secret_access_key
