`upstream` is not needed as a setting; just set if unconditionally and remove all documentation and tests for it. At some point we want remove the hanlding for `upstream` as well and error out on seeing it. Signed-off-by: Miek Gieben <miek@miek.nl>

# federation
|
|
|
|
## Name
|
|
|
|
*federation* - enables federated queries to be resolved via the kubernetes plugin.
|
|
|
|
## Description
|
|
|
|
Enabling this plugin allows
|
|
[Federated](https://kubernetes.io/docs/tasks/federation/federation-service-discovery/) queries to be
|
|
resolved via the kubernetes plugin.
|
|
|
|
Enabling *federation* without also having *kubernetes* is a noop.
|
|
|
|
## Syntax
|
|
|
|
~~~
|
|
federation [ZONES...] {
|
|
NAME DOMAIN
|
|
}
|
|
~~~
|
|
|
|
* Each **NAME** and **DOMAIN** defines federation membership. One entry for each. A duplicate
|
|
**NAME** will silently overwrite any previous value.
|
|
|
|
## Examples
|
|
|
|
Here we handle all service requests in the `prod` and `stage` federations.
|
|
|
|
~~~
|
|
. {
|
|
kubernetes cluster.local
|
|
federation cluster.local {
|
|
prod prod.feddomain.com
|
|
staging staging.feddomain.com
|
|
}
|
|
forward . 192.168.1.12
|
|
}
|
