   -d, --domain          Domain(s) to update [required] (you can specify multiple domains, ex: -d ro.domain.com -d en.domain.com)
   -z, --zone            Route 53 Zone ID that the domain lives in [default: searches all zones for domain]
   -ttl, --ttl           Time To Leave (in seconds) [default: 60]
   -t, --time            How frequently to check for IP update [default: 60]
   -o, --once            Check for IP update ONLY ONCE and exit [default: false]
   -g, --growl           Display growl notification after IP update [default: false]
   -aws, --awskeys       The path for the config file containing AWS credentials [default ~/.awsrc]

   -dbg, --debug         Print debugging info
   -v, --version         Print version and exit

Installation

$ npm install -g dynroute

Usage

• Create a hosted zone for your domain in Route53, in case you don't already have one.
• Update your domain's nameservers with the ones provided by Route53 (for that hosted zone).
• Put your credentials into a config file such as ~/.awsrc (used by default)

[credentials]
accessKeyId     = AAAAAAAAAAAAAAAAAAAA
secretAccessKey = bbbbbbbbbbbbbbbbbbbbbLwccccembeMdddddI4e

Note that you might want to create another AWS user has CRUD rights for Route53 and use that instead of the admin account. Here's a sample AWS user policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "route53:ListHostedZones",
                "route53:ListResourceRecordSets",
                "route53:ChangeResourceRecordSets",
                "route53:CreateHostedZone",
                "route53domains:*"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

Update now & exit

dynroute -d home.mydomain.com --once

Leave script open to check for updated every X seconds

dynroute -d home.mydomain.com

By default the script will check every 60 seconds if your ip updated, but you can customize that:

dynroute -d home.mydomain.com --time 120

Growl

You can setup Growl notifications to let you know when your IP has been updated for your domain.

Ex:

dynroute -d localhost.mydomain.com --growl

What if the record doesn't exist for that domain?

If there is no A record for that hosted zone that matches your request the script will automatically create one.
