--- name: Route 53 layout: default jsId: ROUTE53 --- # Amazon Route 53 Provider ## Configuration You can specify the API credentials in the credentials json file: {% highlight json %} { "r53_main": { "KeyId": "your-aws-key", "SecretKey": "your-aws-secret-key", "Token": "optional-sts-token", "DelegationSet" : "optional-delegation-set-id" } } {% endhighlight %} 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 ``` {% highlight json %} { "r53_main": { "KeyId": "$AWS_ACCESS_KEY_ID", "SecretKey": "$AWS_SECRET_ACCESS_KEY" } } {% endhighlight %} Alternatively if you want to used [named profiles](https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html) you need to export the following variables ``` $ export AWS_SDK_LOAD_CONFIG=1 $ export AWS_PROFILE=ZZZZZZZZ ``` You can find some other ways to authenticate to Route53 in the [go sdk configuration](https://docs.aws.amazon.com/sdk-for-go/v1/developer-guide/configuring-sdk.html). ## Metadata This provider does not recognize any special metadata fields unique to route 53. ## Usage Example Javascript: {% highlight js %} 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') ); {% endhighlight %} ## Activation DNSControl depends on a standard [AWS access key](https://aws.amazon.com/developers/access-keys/) 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: {% highlight json %} { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "route53:CreateHostedZone", "route53:GetHostedZone", "route53:ListHostedZones", "route53:ChangeResourceRecordSets", "route53:ListResourceRecordSets", "route53:UpdateHostedZoneComment" ], "Resource": "*" } ] } {% endhighlight %} 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 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](https://github.com/StackExchange/dnscontrol/pull/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. ### 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.
