Amazon Route 53

Configuration
To use this provider, add an entry to creds.json with TYPE set to ROUTE53 along with API credentials.
Example:
creds.json
{
  "r53_main": {
    "TYPE": "ROUTE53",
    "DelegationSet": "optional-delegation-set-id",
    "KeyId": "your-aws-key",
    "SecretKey": "your-aws-secret-key",
    "Token": "optional-sts-token"
  }
}
Alternatively you can also use environment variables. 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
creds.json
{
  "r53_main": {
    "KeyId": "$AWS_ACCESS_KEY_ID",
    "SecretKey": "$AWS_SECRET_ACCESS_KEY",
    "TYPE": "ROUTE53"
  }
}
Alternatively, this provider supports named profiles. In that case export the following variable:
export AWS_PROFILE=ZZZZZZZZ
and provide a minimal entry in creds.json:
Example:
creds.json
{
  "r53_main": {
    "TYPE": "ROUTE53"
  }
}
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
An example configuration:
dnsconfig.js
var REG_NONE = NewRegistrar("none");
var DSP_R53 = NewDnsProvider("r53_main");
​
D("example.tld", REG_NONE, DnsProvider(DSP_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. If you do not have the permissions required you will receive the following error message Check your credentials, your not authorized to perform actions on Route 53 AWS Service.
You can apply the AmazonRoute53FullAccess policy however this includes access to many other areas of AWS. The minimum permissions required are as follows:
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "route53:CreateHostedZone",
                "route53:GetHostedZone",
                "route53:ListHostedZones",
                "route53:ChangeResourceRecordSets",
                "route53:ListResourceRecordSets",
                "route53:UpdateHostedZoneComment"
            ],
            "Resource": "*"
        }
    ]
}
If Route53 is also your registrar, you will need route53domains:UpdateDomainNameservers and route53domains:GetDomainDetail as well and possibly others.
New domains
If a domain does not exist in your Route53 account, DNSControl will not automatically add it with the push command. You can do that either manually via the control panel, or via the command dnscontrol create-domains command.
Delegation Sets
Creation of new delegation sets are not supported by this code. However, if you have a delegation set already created, ala:
aws route53 create-reusable-delegation-set --caller-reference "foo"
{
    "Location": "https://route53.amazonaws.com/2013-04-01/delegationset/12312312123",
    "DelegationSet": {
        "Id": "/delegationset/12312312123",
        "CallerReference": "foo",
        "NameServers": [
            "ns-1056.awsdns-04.org",
            "ns-215.awsdns-26.com",
            "ns-1686.awsdns-18.co.uk",
            "ns-970.awsdns-57.net"
        ]
    }
}
You can then reference the DelegationSet.Id in your r53_main block (with your other credentials) to have all created domains placed in that delegation set. Note that you you only want the portion of the Id after the /delegationset/ (the 12312312123 in the example above).
Delegation sets only apply during create-domains at the moment. Further work needs to be done to have them apply during push.
Caveats
Route53 errors if it is not the DnsProvider
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: (This output assumes the --full flag)
----- 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.
Bug when converting new zones
You will see some weirdness if:
1.A CNAME was created using the web UI
2.The CNAME's target does NOT end with a dot.
What you will see: When DNSControl tries to update such records, R53 only updates the first one. For example if DNSControl is updating 3 such records, you will need to run dnscontrol push three times for all three records to update. Each time DNSControl is sending three modify requests but only the first is executed. After all such records are modified by DNSControl, everything works as expected.
We believe this is a bug with R53.
This is only a problem for users converting old zones to DNSControl.
NOTE: When converting zones that include such records, the get-zones command will generate CNAME() records without the trailing dot. You should manually add the dot. Run dnscontrol preview as normal to check your work. However when you run dnscontrol push you'll find you have to run it multiple times, each time one of those corrections executes and the others do not. Once all such records are replaced this problem disappears.
More info is available in #891.
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") 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.
Incomplete Signature
dnscontrol preview
IncompleteSignature: 'ABCDEFGHIJKLMNOPQRST/20200118/us-east-1/route53/aws4_request' not a valid key=value pair (missing equal-sign) in Authorization header: 'AWS4-HMAC-SHA256 Credential= ABCDEFGHIJKLMNOPQRST/20200118/us-east-1/route53/aws4_request, SignedHeaders=host;x-amz-date, Signature=571c0b13205669a338f0fb9f351dc03c7016c8737c738081bc885c68378ad877'.
        status code: 403, request id: 12a34b5c-d678-9e01-f2gh-3456i7jk89lm
This means a space is present in one or more of the credential values.
