This repository contains the code and instructions for the hpcloud-kubesetup installer, which deploys a Kubernetes cluster to the HP Helion Public Cloud or to any HP Helion OpenStack environment. The process runs on your workstation, provisioning the cluster remotely.
- A valid hpcloud.com account or valid credentials to your Helion OpenStack environment.
- CoreOS available as a guest image if using your own Helion OpenStack environment.
- A Linux, Mac, or Windows workstation with internet connectivity.

Download the hpcloud-kubesetup installer for your specific platform:
Linux
wget https://raw.githubusercontent.com/hpcloud/hpcloud-kubesetup/master/bin/hpcloud-kubesetup_linux_amd64 -O /usr/local/bin/hpcloud-kubesetup chmod +x /usr/local/bin/hpcloud-kubesetupMac
wget https://raw.githubusercontent.com/hpcloud/hpcloud-kubesetup/master/bin/hpcloud-kubesetup_darwin_amd64 -O /usr/local/bin/hpcloud-kubesetup chmod +x /usr/local/bin/hpcloud-kubesetupWindows
wget https://raw.githubusercontent.com/hpcloud/hpcloud-kubesetup/master/bin/hpcloud-kubesetup_windows_amd64.exe -O %temp%/hpcloud-kubesetup.exe -
Download the default setup configuration file to create a 4 node Kubernetes cluster
Linux, Mac, Windows
wget https://raw.githubusercontent.com/hpcloud/hpcloud-kubesetup/master/kubesetup.yml -
Log into your account and download the "OpenStack RC file" located on the Project\Access & Security panel inside the API Access tab. The download button is on the top right corner.
-
Execute the OpenStack resource script. The script will ask you to enter your OpenStack password. All settings will be exported as environment variables.
Linux
source ./<your project name>-openrc.shMac
source ./<your project name>-openrc.shWindows
Coming soonTo inspect what was exported, run
export | grep OS_. You should see a similar result to:$ export | grep OS_ declare -x OS_AUTH_URL="https://region-a.geo-1.identity.hpcloudsvc.com:35357/v2.0/" declare -x OS_PASSWORD="My Very Secret Password" declare -x OS_TENANT_ID="12345678901234" declare -x OS_TENANT_NAME="kubernetes" declare -x OS_USERNAME="kube" -
Update
kubesetup.ymlif needed. This file describes the setup of the cluster. By default, a cluster consisting of 5 nodes, 1 master node and 4 minion nodes, will be created. You will need to create a new ssh key namedkube-keyor modifysshkeyto reflect the key you want to use instead.kubesetup.yml
hosts: kube-master: ip: 10.0.0.40 ismaster: true vm-image: CoreOS vm-size: standard.medium kube-minion-1: ip: 10.0.0.41 ismaster: false vm-image: CoreOS vm-size: standard.small kube-minion-2: ip: 10.0.0.42 ismaster: false vm-image: CoreOS vm-size: standard.small kube-minion-3: ip: 10.0.0.43 ismaster: false vm-image: CoreOS vm-size: standard.small kube-minion-4: ip: 10.0.0.44 ismaster: false vm-image: CoreOS vm-size: standard.small sshkey: kube-key -
Once
kubesetup.ymlreflects the type of cluster you want to create, you can then execute the cluster installer:Linux
/usr/local/bin/hpcloud-kubesetupMac
./usr/local/bin/hpcloud-kubesetupWindows
coming soonOnce run, you should see the following results:

The installer associates a floating IP address with the Kubernetes master node. The next step is to ssh in to the master node and run the Kubernetes kubecfg tool to list the minions and verify everything is working properly.

After verifying all the nodes are there, you are ready to rock and roll. The next step would be to deploy a sample application to the cluster. Happy containerizing!
