Objective

Learn how to set up a machine on Rackspace to deploy a SOAJS cloud on it.

Steps

Create an account on Rackspace
Create a machine
1. Specify which image to use and which flavor
2. Save the provided password
Connect to the Machine using the saved password
Download the pre-requisites, the installer & run the Installer pre script on the machine
1. Copy the Kubernetes Token

Step 1: Create an account on Rackspace

Begin by Creating a Rackspace account → Click Here.
- Follow the steps of Rackspace wizard

Step 2: Create a machine

Click on Servers → Create Resources → Cloud servers
Specify the machine image type, OS and version: Linux - Ubuntu - 16.04 LTS(Xenial Xerus)
Specify the flavor: 7.5 GB Compute v1
Click Create Server
Save the password to use it for establishing the connection
Wait till the server gets ready
Use the ssh to log into your server

Create the machine

Running machine

Step 3: Connect to the Machine on your Local Machine

Connect to the Machine

# connect to the machine using the IP address and the saved password
> ssh root@machine-Ip-address

Step 4: Download the pre-requisites, the installer & run the Installer pre script on Rackspace Machine

Once you SSH to the machine, you can download and run the installer pre installation script to get all the dependencies so that cloud deployment works.

Prepare the machine

Download & Run SOAJS Installer pre scripts

# download update apt-get, npm and zip
> sudo su
> apt-get update && apt-get -y upgrade
> apt-get install npm

# download the latest version of nodejs
> curl -sL https://deb.nodesource.com/setup_6.x | bash && apt-get install -y nodejs

Run the installer

# download installer 
> mkdir -p /opt/soajs/node_modules 
> cd /opt/soajs/node_modules 
> sudo npm install soajs.installer 

# run installer pre script 
> cd soajs.installer/scripts/pre 
> sudo /opt/soajs/node_modules/soajs.installer/scripts/pre/kubernetes-linux.sh <%YOUR_CUSTOM_DOMAIN%>

# By default, your cluster will not schedule pods on the master for security reasons. 
# If you want to be able to schedule pods on the master, e.g. for a single-machine Kubernetes cluster for development, run
> kubectl taint nodes --all node-role.kubernetes.io/master:NoSchedule-

Grab the kubernetes Secret

Grab the kubernetes secret token by running the below command

Grab the Kubernetes Secret Token

# get kubernetes secrets
> kubectl describe secrets
