aws_serv_disc

An experimental erlang nif that leverages the aws c++ sdk for service discovery. This library provides functions aws_serv_disc:list_instances/1,2,3, an example is below:

Eshell V10.2.4  (abort with ^G)
1> aws_serv_disc:list_instances("srv-asfgdasfds21").
{ok,#{"Instances" =>
          [#{"Attributes" =>
                 #{"AVAILABILITY_ZONE" => "us-west-1c",
                   "AWS_INIT_HEALTH_STATUS" => "HEALTHY",
                   "AWS_INSTANCE_IPV4" => "10.0.2.4",
                   "AWS_INSTANCE_PORT" => "32768",
                   "EC2_INSTANCE_ID" => "i-01275c4793319ee89",
                   "ECS_CLUSTER_NAME" => "ClusterStack-Cluster",
                   "ECS_SERVICE_NAME" => "erlang-service",
                   "ECS_TASK_DEFINITION_FAMILY" => "erlang-service",
                   "REGION" => "us-west-1"},
             "Id" => "ccabd341-6b1e-4a84-99d3-a0f4c3fbbce5"}],
      "NextToken" => undefined}}

This library has only been tested on ubuntu 16.04.
