## Test scripts to automate kubernetes startup
Requirements:
docker
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,
Use docker container (instead of binary) for kubectl and travis cleanup (#352) This fix uses docker container for kubectl. Since Kubernetes docker image hyperkube has already been downloaded and it consists of kubectl, there is really no need to download kubectl binary again. This fix cleans up the Kubernetes related travis setup and removes unneeded scripts. This fix also fixes several mismatches of the Kubernetes version used, so that any changes in version in the future only need to update .travis.yml.
