Went over all generated manual pages and fixed some markdown issues, mostly escaping "_" to avoid underlining entire paragraphs. Some textual fixes in route53 and other cloud DNS plugins. Regenerated the markdown with mmark. Signed-off-by: Miek Gieben <miek@miek.nl>

# clouddns
|
|
|
|
## Name
|
|
|
|
*clouddns* - enables serving zone data from GCP Cloud DNS.
|
|
|
|
## Description
|
|
|
|
The *clouddns* plugin is useful for serving zones from resource record
|
|
sets in GCP Cloud DNS. This plugin supports all [Google Cloud DNS
|
|
records](https://cloud.google.com/dns/docs/overview#supported_dns_record_types). This plugin can
|
|
be used when CoreDNS is deployed on GCP or elsewhere. Note that this plugin accesses the resource
|
|
records through the Google Cloud API. For records in a privately hosted zone, it is not necessary to
|
|
place CoreDNS and this plugin in the associated VPC network. In fact the private hosted zone could
|
|
be created without any associated VPC and this plugin could still access the resource records under
|
|
the hosted zone.
|
|
|
|
## Syntax
|
|
|
|
~~~ txt
|
|
clouddns [ZONE:PROJECT_ID:HOSTED_ZONE_NAME...] {
|
|
credentials [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.
|
|
|
|
* **PROJECT\_ID** the project ID of the Google Cloud project.
|
|
|
|
* **HOSTED\_ZONE\_NAME** the name of the hosted zone that contains the resource record sets to be
|
|
accessed.
|
|
|
|
* `credentials` is used for reading the credential file from **FILENAME** (normally a .json file).
|
|
|
|
* `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.
|
|
|
|
## Examples
|
|
|
|
Enable clouddns with implicit GCP credentials and resolve CNAMEs via 10.0.0.1:
|
|
|
|
~~~ txt
|
|
example.org {
|
|
clouddns example.org.:gcp-example-project:example-zone
|
|
forward . 10.0.0.1
|
|
}
|
|
~~~
|
|
|
|
Enable clouddns with fallthrough:
|
|
|
|
~~~ txt
|
|
example.org {
|
|
clouddns example.org.:gcp-example-project:example-zone example.com.:gcp-example-project:example-zone-2 {
|
|
fallthrough example.gov.
|
|
}
|
|
}
|
|
~~~
|
|
|
|
Enable clouddns with multiple hosted zones with the same domain:
|
|
|
|
~~~ txt
|
|
. {
|
|
clouddns example.org.:gcp-example-project:example-zone example.com.:gcp-example-project:other-example-zone
|
|
}
|
|
