What's it for

aws_public_ips is a tool to fetch all public IP addresses (both IPv4/IPv6) associated with an AWS account.

It can be used as a library and as a CLI, and supports the following AWS services (all with both Classic & VPC flavors):

• APIGateway
• CloudFront
• EC2 (and as a result: ECS, EKS, Beanstalk, Fargate, Batch, & NAT Instances)
• ElasticSearch
• ELB (Classic ELB)
• ELBv2 (ALB/NLB)
• Lightsail
• RDS
• Redshift

If a service isn't listed (S3, ElastiCache, etc) it's most likely because it doesn't have anything to support (i.e. it might not be deployable publicly, it might have all ip addresses resolve to global AWS infrastructure, etc).

Quick start

Install the gem and run it:

$ gem install aws_public_ips

# Uses default ~/.aws/credentials
$ aws_public_ips
52.84.11.13
52.84.11.83
2600:9000:2039:ba00:1a:cd27:1440:93a1
2600:9000:2039:6e00:1a:cd27:1440:93a1

# With a custom profile
$ AWS_PROFILE=production aws_public_ips
52.84.11.159

The gem can also be run from Docker:

$ docker pull arkadiyt/aws_public_ips

# For credentials, ensure the appropriate environment variables are defined in the host environment:
$ docker run -e AWS_REGION -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY -e AWS_SESSION_TOKEN arkadiyt/aws_public_ips

CLI reference

$ aws_public_ips --help

Configuration

For authentication aws_public_ips uses the default aws-sdk-ruby configuration, meaning that the following are checked in order:

1. Environment variables:

• AWS_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY
• AWS_REGION
• AWS_PROFILE

2. Shared credentials files:

• ~/.aws/credentials
• ~/.aws/config

3. Instance profile via metadata endpoint (if running on EC2, ECS, EKS, or Fargate)

For more information see the AWS SDK documentation on configuration.

IAM permissions

To find the public IPs from all AWS services, the minimal policy needed by your IAM user is:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "apigateway:GET",
        "cloudfront:ListDistributions",
        "ec2:DescribeInstances",
        "elasticloadbalancing:DescribeLoadBalancers",
        "lightsail:GetInstances",
        "lightsail:GetLoadBalancers",
        "rds:DescribeDBInstances",
        "redshift:DescribeClusters",
        "es:ListDomainNames"
      ],
      "Resource": "*"
    }
  ]
}
