ClusterEC2

This is an EC2 clustering strategy for libcluster. It currently supports identifying nodes based on EC2 tags.

The default Tags strategy uses ex_aws to query the EC2 DescribeInstances API endpoint. Access to this API should be granted to the EC2 instance profile. See the ExAws docs for additional configuration options.

config :libcluster,
  topologies: [
    example: [

      config: [
        ec2_tagname: "elasticbeanstalk:environment-name"
      ],
    ]
  ]
