Kubernetes demo

These scripts can be used for quick bootstrapping of Kubernetes and Etcd cluster. Predefined values are prepared for running on localhost but it can be easily changes to multi node scenario.

Configuration variables

Name	Default	Description
ETCD_IMAGE	quay.io/coreos/etcd:v2.2.0	etcd is running from this image
ETCD_NAME	0	cluster name of etcd server
ETCD_LISTEN_IP	127.0.0.1	etcd listen on this address
ETCD_ADVERTISE_IP	127.0.0.1	address advetised to etcd clients
MASTER	127.0.0.1	address of Kubernetes master (API server)
NODE_IP	127.0.0.1
SERVICERANGE	172.18.0.0/24	IP range used for Kubernetes services
IMAGE	gcr.io/google_containers/hyperkube-amd64:v1.2.3	Kubernetes components are using this image
ETCD_SERVERS	http://127.0.0.1:4001	Kubernetes uses this etcd server
RESTART	no	Restart policy for Kubernetes containers

Usage

1. Prepare before demo (pull images)

   ./etcd.sh pull-only
   ./kubernetes.sh pull-only

2. Start etcd server

   ./etcd.sh

3. (Optional) Test etcd server

   ./bin/etcdctl set /me $(whoami) && ./bin/etcdctl get /me

4. Start Kubernetes services

   1. API server

      ./kubernetes.sh apiserver

   2. Controller Manager

      ./kubernetes.sh controller-manager

   3. Scheduler

      ./kubernetes.sh scheduler

   4. Proxy

      ./kubernetes.sh proxy

   5. Kubelet

      ./kubernetes.sh kubelet

5. Create sample app in Kubernetes

   1. Create replication controller

      ./bin/kubectl create -f conf/nginx-rc.yml

   2. Create service

      ./bin/kubectl create -f conf/nginx-svc.yml

6. Enjoy
