# route53
|
|
|
|
## Name
|
|
|
|
*route53* - enables serving zone data from AWS route53.
|
|
|
|
## Description
|
|
|
|
The route53 plugin is useful for serving zones from resource record
|
|
sets in AWS route53. This plugin supports all Amazon Route 53 records
|
|
([https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/ResourceRecordTypes.html](https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/ResourceRecordTypes.html)).
|
|
The route53 plugin can be used when coredns is deployed on AWS or elsewhere.
|
|
|
|
## Syntax
|
|
|
|
~~~ txt
|
|
route53 [ZONE:HOSTED_ZONE_ID...] {
|
|
[aws_access_key AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY]
|
|
upstream
|
|
credentials PROFILE [FILENAME]
|
|
fallthrough [ZONES...]
|
|
}
|
|
~~~
|
|
|
|
* **ZONE** the name of the domain to be accessed. When there are multiple zones with overlapping
|
|
domains (private vs. public hosted zone), CoreDNS does the lookup in the given order here.
|
|
Therefore, for a non-existing resource record, SOA response will be from the rightmost zone.
|
|
|
|
* **HOSTED*ZONE*ID** the ID of the hosted zone that contains the resource record sets to be
|
|
accessed.
|
|
|
|
* **AWS*ACCESS*KEY_ID** and **AWS*SECRET*ACCESS_KEY** the AWS access key ID and secret access key
|
|
to be used when query AWS (optional). If they are not provided, then coredns tries to access
|
|
AWS credentials the same way as AWS CLI, e.g., environmental variables, AWS credentials file,
|
|
instance profile credentials, etc.
|
|
|
|
* `upstream`is used for resolving services that point to external hosts (eg. used to resolve
|
|
CNAMEs). CoreDNS will resolve against itself.
|
|
|
|
* `credentials` is used for reading the credential file and setting the profile name for a given
|
|
zone.
|
|
|
|
* **PROFILE** AWS account profile name. Defaults to `default`.
|
|
|
|
* **FILENAME** AWS credentials filename. Defaults to `~/.aws/credentials` are used.
|
|
|
|
* `fallthrough` If zone matches and no record can be generated, pass request to the next plugin.
|
|
If **[ZONES...]** is omitted, then fallthrough happens for all zones for which the plugin is
|
|
authoritative. If specific zones are listed (for example `in-addr.arpa` and `ip6.arpa`), then
|
|
only queries for those zones will be subject to fallthrough.
|
|
|
|
* **ZONES** zones it should be authoritative for. If empty, the zones from the configuration block

## Examples
|
|
|
|
Enable route53 with implicit AWS credentials and an upstream:
|
|
|
|
~~~ txt
|
|
. {
|
|
route53 example.org.:Z1Z2Z3Z4DZ5Z6Z7 {
|
|
upstream 10.0.0.1
|
|
}
|
|
}
|
|
~~~
|
|
|
|
Enable route53 with explicit AWS credentials:
|
|
|
|
~~~ txt
|
|
. {
|
|
route53 example.org.:Z1Z2Z3Z4DZ5Z6Z7 {
|
|
aws_access_key AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY
|
|
}
|
|
}
|
|
~~~
|
|
|
|
Enable route53 with fallthrough:
|
|
|
|
~~~ txt
|
|
. {
|
|
route53 example.org.:Z1Z2Z3Z4DZ5Z6Z7 example.gov.:Z654321543245 {
|
|
fallthrough example.gov.
|
|
}
|
|
}
|
|
~~~
|
|
|
|
Enable route53 with multiple hosted zones with the same domain:
|
|
|
|
~~~ txt
|
|
. {
|
|
route53 example.org.:Z1Z2Z3Z4DZ5Z6Z7 example.org.:Z93A52145678156
