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>

\fIroute53\fP - enables serving zone data from AWS route53.
|
|
|
|
.SH "DESCRIPTION"
|
|
.PP
|
|
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
|
|
\[la]https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/ResourceRecordTypes.html\[ra]).
|
|
The route53 plugin can be used when coredns is deployed on AWS or elsewhere.

.IP \(bu 4
|
|
\fBZONE\fP 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.
|
|
.IP \(bu 4
|
|
\fBHOSTED_ZONE_ID\fP the ID of the hosted zone that contains the resource record sets to be
|
|
accessed.
|
|
.IP \(bu 4
|
|
\fBAWS_ACCESS_KEY_ID\fP and \fBAWS_SECRET_ACCESS_KEY\fP 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.
|
|
.IP \(bu 4
|
|
\fB\fCcredentials\fR is used for reading the credential \fBFILENAME\fP and setting the \fBPROFILE\fP name for a given
|
|
zone. \fBPROFILE\fP is the AWS account profile name. Defaults to \fB\fCdefault\fR. \fBFILENAME\fP is the
|
|
AWS credentials filename, defaults to \fB\fC~/.aws/credentials\fR.
|
|
.IP \(bu 4
|
|
\fB\fCfallthrough\fR If zone matches and no record can be generated, pass request to the next plugin.
|
|
If \fBZONES\fP is omitted, then fallthrough happens for all zones for which the plugin is
|
|
authoritative. If specific zones are listed (for example \fB\fCin-addr.arpa\fR and \fB\fCip6.arpa\fR), then
|
|
only queries for those zones will be subject to fallthrough.
|
|
.IP \(bu 4
|
|
\fB\fCrefresh\fR can be used to control how long between record retrievals from Route 53. It requires
|
|
a duration string as a parameter to specify the duration between update cycles. Each update
|
|
cycle may result in many AWS API calls depending on how many domains use this plugin and how
|
|
many records are in each. Adjusting the update frequency may help reduce the potential of API
|
|
rate-limiting imposed by AWS.
|
|
.IP \(bu 4
|
|
\fBDURATION\fP A duration string. Defaults to \fB\fC1m\fR. If units are unspecified, seconds are assumed.
