Build Docker images from upstream binaries.
tldr; The following commands will stand up a single node Kubernetes cluster using docker-compose
export DOCKER_HOST="tcp://172.16.238.194:2375"
git clone https://github.com/kelseyhightower/kubernetes-docker-files.git
cd kubernetes-docker-files
docker-compose up -d
Testing out the cluster:
kubectl cluster-info -s http://172.16.238.194:8080
Kubernetes master is running at http://172.16.238.194:8080
Run some pods
kubectl run -s http://172.16.238.194:8080 memcached --image=memcached
CONTROLLER CONTAINER(S) IMAGE(S) SELECTOR REPLICAS

kubectl get pods -s http://172.16.238.194:8080
