## Test scripts to automate kubernetes startup
Requirements:
docker
curl
The scripts in this directory startup kubernetes with docker as the container runtime.
After starting kubernetes, a couple of kubernetes services are started to allow automatic

testing of CoreDNS with kubernetes. The kubernetes integration tests in `test/kubernetes_test.go` depend on having some sample services running. The scripts in this folder
automate the launch of kubernetes and the creation of the expected sample services.

To start up kubernetes and launch some sample services,
run the script `start_k8s_with_services.sh`.
~~~
$ ./start_k8s_with_services.sh

Alternatively, the individual scripts may be run independently as needed:

After running the above scripts, kubernetes will be running on the localhost with the following services
exposed:
~~
NAMESPACE NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
default kubernetes 10.0.0.1 <none> 443/TCP 48m
demo mynginx 10.0.0.168 <none> 80/TCP 9m
demo webserver 10.0.0.28 <none> 80/TCP 2m
test mynginx 10.0.0.4 <none> 80/TCP 2m
test webserver 10.0.0.39 <none> 80/TCP 2m
~~
Kubernetes and all running containers can be uncerimoniously stopped by
running the `kill_all_containers.sh` script.
~~~
$ ./kill_all_containers.sh
