| # consul | ||
|
|
||
| ## Name | ||
|
|
||
| *consul* - enables SkyDNS service discovery from consul. | ||
|
|
||
| ## Description | ||
|
|
||
| The *consul* plugin implements the (older) SkyDNS service discovery service. It is *not* suitable as | ||
| a generic DNS zone data plugin. Only a subset of DNS record types are implemented, and subdomains | ||
| and delegations are not handled at all. | ||
|
|
||
| The data in the consul instance has to be encoded as | ||
| a [message](https://github.com/skynetservices/skydns/blob/2fcff74cdc9f9a7dd64189a447ef27ac354b725f/msg/service.go#L26) | ||
| like [SkyDNS](https://github.com/skynetservices/skydns). It works just like SkyDNS. | ||
|
|
||
| The consul plugin makes extensive use of the *forward* plugin to forward and query other servers in the | ||
| network. | ||
|
|
||
| ## Syntax | ||
|
|
||
| ~~~ | ||
| consul [ZONES...] | ||
| ~~~ | ||
|
|
||
| * **ZONES** zones *consul* should be authoritative for. | ||
|
|
||
| The path will default to `/skydns` the local consul proxy (http://localhost:8500). If no zones are | ||
| specified the block's zone will be used as the zone. | ||
|
|
||
| If you want to `round robin` A and AAAA responses look at the `loadbalance` plugin. | ||
|
|
||
| ~~~ | ||
| consul [ZONES...] { | ||
| fallthrough [ZONES...] | ||
| path PATH | ||
| address address | ||
| token token | ||
| } | ||
| ~~~ | ||
|
|
||
| * `fallthrough` If zone matches but 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. | ||
| * **PATH** the path inside consul. Defaults to "/skydns". | ||
| * **ADDRESS** the consul endpoints. Defaults to "http://localhost:8500". | ||
|
|
||
|
|
||
| ## Special Behaviour | ||
|
|
||
| The *consul* plugin leverages directory structure to look for related entries. For example | ||
| an entry `/skydns/test/skydns/mx` would have entries like `/skydns/test/skydns/mx/a`, | ||
| `/skydns/test/skydns/mx/b` and so on. Similarly a directory `/skydns/test/skydns/mx1` will have all | ||
| `mx1` entries. | ||
|
|
||
| ## Examples | ||
|
|
||
| This is the default SkyDNS setup, with everything specified in full: | ||
|
|
||
| ~~~ corefile | ||
| skydns.local { | ||
| consul { | ||
| path /skydns | ||
| address http://localhost:8500 | ||
| token xxxx-xxxx-xxxx-xxxx-xxxx | ||
| } | ||
| prometheus | ||
| cache | ||
| loadbalance | ||
| } | ||
| . { | ||
| forward . 8.8.8.8:53 8.8.4.4:53 | ||
| cache | ||
| } | ||
| ~~~ | ||
|
|
||
| Or a setup where we use `/etc/resolv.conf` as the basis for the proxy and the upstream | ||
| when resolving external pointing CNAMEs. | ||
|
|
||
| ~~~ corefile | ||
| skydns.local { | ||
| consul { | ||
| path /skydns | ||
| } | ||
| cache | ||
| } | ||
| . { | ||
| forward . /etc/resolv.conf | ||
| cache | ||
| } | ||
| ~~~ | ||
|
|
||
|
|
||
| ### Reverse zones | ||
|
|
||
| Reverse zones are supported. You need to make CoreDNS aware of the fact that you are also | ||
| authoritative for the reverse. For instance if you want to add the reverse for 10.0.0.0/24, you'll | ||
| need to add the zone `0.0.10.in-addr.arpa` to the list of zones. Showing a snippet of a Corefile: | ||
|
|
||
| ~~~ | ||
| consul skydns.local 10.0.0.0/24 { | ||
| ... | ||
| ~~~ | ||
|
|
||
| Next you'll need to populate the zone with reverse records, here we add a reverse for | ||
| 10.0.0.127 pointing to reverse.skydns.local. | ||
|
|
||
| ~~~ | ||
| % /skydns/arpa/in-addr/10/0/0/127 '{"host":"reverse.skydns.local."}' | ||
| ~~~ | ||
|
|
||
| Querying with dig: | ||
|
|
||
| ~~~ sh | ||
| % dig @localhost -x 10.0.0.127 +short | ||
| reverse.skydns.local. | ||
| ~~~ | ||
|
|
||
| ### Zone name as A record | ||
|
|
||
| The zone name itself can be used as an `A` record. This behavior can be achieved by writing special | ||
| entries to the ETCD path of your zone. If your zone is named `skydns.local` for example, you can | ||
| create an `A` record for this zone as follows: | ||
|
|
||
| ~~~ | ||
| % /skydns/local/skydns/ '{"host":"1.1.1.1","ttl":60}' | ||
| ~~~ | ||
|
|
||
| If you query the zone name itself, you will receive the created `A` record: | ||
|
|
||
| ~~~ sh | ||
| % dig +short skydns.local @localhost | ||
| 1.1.1.1 | ||
| ~~~ | ||
|
|
||
| If you would like to use DNS RR for the zone name, you can set the following: | ||
| ~~~ | ||
| % /skydns/local/skydns/x1 '{"host":"1.1.1.1","ttl":60}' | ||
| % /skydns/local/skydns/x2 '{"host":"1.1.1.2","ttl":60}' | ||
| ~~~ | ||
|
|
||
| If you query the zone name now, you will get the following response: | ||
|
|
||
| ~~~ sh | ||
| % dig +short skydns.local @localhost | ||
| 1.1.1.1 | ||
| 1.1.1.2 | ||
| ~~~ | ||
|
|
||
| ### Zone name as AAAA record | ||
|
|
||
| If you would like to use `AAAA` records for the zone name too, you can set the following: | ||
| ~~~ | ||
| % /skydns/local/skydns/x3 '{"host":"2003::8:1","ttl":60}' | ||
| % /skydns/local/skydns/x4 '{"host":"2003::8:2","ttl":60}' | ||
| ~~~ | ||
|
|
||
| If you query the zone name for `AAAA` now, you will get the following response: | ||
| ~~~ sh | ||
| % dig +short skydns.local AAAA @localhost | ||
| 2003::8:1 | ||
| 2003::8:2 | ||
| ~~~ | ||
|
|
||
| ### SRV record | ||
|
|
||
| If you would like to use `SRV` records, you can set the following: | ||
| ~~~ | ||
| % /skydns/local/skydns/x5 '{"host":"skydns-local.server","ttl":60,"priority":10,"port":8080}' | ||
| ~~~ | ||
| Please notice that the key `host` is the `target` in `SRV`, so it should be a domain name. | ||
|
|
||
| If you query the zone name for `SRV` now, you will get the following response: | ||
|
|
||
| ~~~ sh | ||
| % dig +short skydns.local SRV @localhost | ||
| 10 100 8080 skydns-local.server. | ||
| ~~~ | ||
|
|
||
| ### TXT record | ||
|
|
||
| If you would like to use `TXT` records, you can set the following: | ||
| ~~~ | ||
| % /skydns/local/skydns/x6 '{"ttl":60,"text":"this is a random text message."}' | ||
| ~~~ | ||
|
|
||
| If you query the zone name for `TXT` now, you will get the following response: | ||
| ~~~ sh | ||
| % dig +short skydns.local TXT @localhost | ||
| "this is a random text message." | ||
| ~~~ |
