Amazon Route 53 Provider

Configuration

You can specify the API credentials in the credentials json file:

{
 "r53_main":{
      "KeyId": "your-aws-key",
      "SecretKey": "your-aws-secret-key",
      "Token": "optional-sts-token"
 }
}

You can also use environment variables, but this is discouraged, unless your environment provides them already.

$ export AWS_ACCESS_KEY_ID=XXXXXXXXX
$ export AWS_SECRET_ACCESS_KEY=YYYYYYYYY
$ export AWS_SESSION_TOKEN=ZZZZZZZZ
{
 "r53_main":{
      "KeyId": "$AWS_ACCESS_KEY_ID",
      "SecretKey": "$AWS_SECRET_ACCESS_KEY"
 }
}

You can find some other ways to authenticate to Route53 in the go sdk configuration.

Metadata

This provider does not recognize any special metadata fields unique to route 53.

Usage

Example Javascript:

var REG_NONE = NewRegistrar('none','NONE');
var R53 = NewDnsProvider('r53_main', 'ROUTE53');

D('example.tld', REG_NONE, DnsProvider(R53),
    A('test','1.2.3.4')
);

Activation

DNSControl depends on a standard AWS access key with permission to list, create and update hosted zones.

New domains

If a domain does not exist in your Route53 account, DNSControl will not automatically add it with the create-domains command. You can do that either manually via the control panel, or via the command dnscontrol create-domains command.

Caveats

This code may not function properly if a domain has R53 as a Registrar but not as a DnsProvider. The situation is described in PR#155.

In this situation you will see a message like:

----- Registrar: r53_main
Error getting corrections: AccessDeniedException: User: arn:aws:iam::868399730840:user/dnscontrol is not authorized to perform: route53domains:GetDomainDetail
  status code: 400, request id: 48b534a1-7902-11e7-afa6-a3fffd2ce139
Done. 1 corrections.

If this happens to you, we’d appreciate it if you could help us fix the code. In the meanwhile, you can give the account additional IAM permissions so that it can do DNS-related actions, or simply use NewRegistrar(..., 'NONE') for now.

Error messages

Creds key mismatch

$ dnscontrol preview
Creating r53 dns provider: NoCredentialProviders: no valid providers in chain. Deprecated.
	For verbose messaging see aws.Config.CredentialsChainVerboseErrors

This means that the creds.json entry isn’t found. Either there is no entry, or the entry name doesn’t match the first parameter in the NewDnsProvider() call. In the above example, note that the string r53_main is specified in NewDnsProvider('r53_main', 'ROUTE53') and that is the exact key used in the creds file above.

Invalid KeyId

$ dnscontrol preview
Creating r53_main dns provider: InvalidClientTokenId: The security token included in the request is invalid.
	status code: 403, request id: 8c006a24-e7df-11e7-9162-01963394e1df

This means the KeyId is unknown to AWS.

Invalid SecretKey

$ dnscontrol preview
Creating r53_main dns provider: SignatureDoesNotMatch: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.
	status code: 403, request id: 9171d89a-e7df-11e7-8586-cbea3ea4e710

This means the SecretKey is incorrect. It may be a quoting issue.
