10 Minute Kubernetes on CoreOS and DigitalOcean Demo

Steps:

Create a DigitalOcean account and upload your public SSH key.

Get the scripts

git clone https://github.com/coreos/coreos-kubernetes
git clone https://github.com/barakmich/10m-k8s
cp 10m-k8s/*.sh coreos-kubernetes
cd coreos-kubernetes

Launch a controller

Run the first CoreOS node on DO, with private networking turned on and the user data being the cloud config at 10m-k8s/single-etcd-cloud-config.yaml

Copy the IP address. This is your controller node. Let's pretend it's 10.1.1.1

# Create the SSL certs
./generate-ssls.sh 10.1.1.1
# Provision the controller
./provision-controller.sh 10.1.1.1 

Kubernetes is now running!

Configure kubectl

Get kubernetes from the official builds and copy kubectl to your $PATH. kubectl is under platforms/<your_platform>/<your_architecture>. Then run

./setup-kubectl.sh my_cool_cluster_name 10.1.1.1 

Add a worker (or five)

You can add a new worker node (spin one up on DO, no need for a cloud-config) and get it's IP. Suppose it's 10.2.2.2 . Run the following:

./provision-worker 10.2.2.2 10.1.1.1

And you're done!
