* mw/federaration This PR add the federation back as a middleware to keep it more contained from the main kubernetes code. It also makes parseRequest less import and pushes this functionlity down in the k.Entries. This minimizes (or tries to) the importance for the qtype in the query. In the end the qtype checking should only happen in ServeDNS - but for k8s this might proof difficult. Numerous other cleanup in code and kubernetes tests. * up test coverage

# federation
|
|
|
|
The *federation* middleware enables
|
|
[federated](https://kubernetes.io/docs/tasks/federation/federation-service-discovery/) queries to be
|
|
resolved via the kubernetes middleware.
|
|
|
|
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.
|
|
|
|
~~~ txt
|
|
. {
|
|
kubernetes cluster.local
|
|
federation cluster.local {
|
|
prod prod.feddomain.com
|
|
staging staging.feddomain.com
|
|
}
|
|
}
|
|
~~~
|
|
|
|
Or slightly shorter:
|
|
|
|
~~~ txt
|
|
cluster.local {
|
|
kubernetes
|
|
federation {
|
|
prod prod.feddomain.com
|
|
staging staging.feddomain.com
|
|
}
|
|
}
|
|
