# Basic Setup for Development and Testing
|
|
|
|
## Launch Kubernetes
|
|
|
|
To run the tests, you'll need a private, live Kubernetes cluster. If you don't have one,
|
|
you can try out [minikube](https://github.com/kubernetes/minikube), which is
|
|
also available via Homebrew for OS X users.
|
|
|
|
## Configure Test Data
|
|
|
|
The test data is all in [this manifest](https://github.com/coredns/coredns/blob/master/.travis/kubernetes/dns-test.yaml)
|
|
and you can load it with `kubectl apply -f`. It will create a couple namespaces and some services.
|
|
For the tests to pass, you should not create anything else in the cluster.
|
|
|
|
## Proxy the API Server
|
|
|
|
Assuming your Kuberentes API server isn't running on http://localhost:8080, you will need to proxy from that
|
|
port to your cluster. You can do this with `kubectl proxy --port 8080`.
|
|
|
|
## Run CoreDNS Kubernetes Tests
|
|
|
|
Now you can run the tests locally, for example:
|
|
|
|
~~~
|
|
$ cd $GOPATH/src/github.com/coredns/coredns/test
|
|
$ go test -v -tags k8s
|
|
~~~
|
|

# Implementation Notes/Ideas
|
|
|
|
* Additional features:
|
|
* Implement IP selection and ordering (internal/external). Related to
|
|
wildcards and SkyDNS use of CNAMES.
|
|
* Expose arbitrary kubernetes repository data as TXT records?
|
|
* DNS Correctness
|
|
* Do we need to generate synthetic zone records for namespaces?
|
|
* Do we need to generate synthetic zone records for the skydns synthetic zones?
|
|
* Test cases
|
|
* Test with CoreDNS caching. CoreDNS caching for DNS response is working
|
|
using the `cache` directive. Tested working using 20s cache timeout
|
|
and A-record queries. Automate testing with cache in place.
|
|
* Automate CoreDNS performance tests. Initially for zone files, and for
|
|
pre-loaded k8s API cache. With and without CoreDNS response caching.
