Assuming you have instances already running in AWS, you can use ops to manage them or, at the very least, you can list them. The tool leverages an AWS tag that needs to be present on the EC2 instances called cluster.

The following examples lists nodes for the defined AWS profile, that have the tag cluster = mycluster1. Check my-aws-cluster.yaml for configuration.

aws configure --profile aam-npe

AWS Access Key ID [None]:
AWS Secret Access Key [None]:
Default region name [None]: us-east-1

$ ops my-aws-cluster.yaml inventory

This will return the list of instances.

You can then SSH to one of the nodes. For instance:

$ ops my-aws-cluster.yaml ssh mywebapp-1
