aws-ec2-easydns

This is a Simple startup script that pushes a A record to route53 on system bootup.

The EC2 instance needs these role permissions:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "ksuquix",
            "Effect": "Allow",
            "Action": [
                "route53:ChangeResourceRecordSets",
                "route53:ListResourceRecordSets"
            ],
            "Resource": "arn:aws:route53:::hostedzone/XXXXXXXXXXXXXXXXXXXXXXX"
        },
        {
            "Sid": "ksuquix2",
            "Effect": "Allow",
            "Action": "route53:ListHostedZones",
            "Resource": "*"
        }
    ]
}

where XXXXXX is your Hosted zone ID

HOSTNAME=myhost.example.com
