#KERBEROS.IO 

What is KiOS?

A Linux OS created by Buildroot which runs Kerberos.io out-of-the-box. This repository cross-compiles for the Raspberry Pi 1, 2 and 3. Below you can find an installation script for Ubuntu 14 and CentOS 7. When the compilation is done, three different images will be available in the current working directory.

How to install KiOS on your Raspberry Pi?

Please go to our documentation website, there is explained the complete process to get started with Kerberos.io.

How to build KiOS on Ubuntu 14

##How to build KiOS on DigitalOcean If you don't want to build KiOS on your local workingstation but you prefer to build it on a VM at DigitalOcean you're at the right place. You will find a script at the root of the KiOS repository named deploy.py.

The python script will need some environment variables and use the DigitalOcean API to create a VM, build KiOS, transfer the images to your local workingstation and destory the VM again.

Environment variables

You'll need to define severable variables; you can add these at the beginning of the deploy script or EXPORT them at your commandline.

# The token from your DigitalOcean account
os.environ['kerberosio_token'] = 'cdae884ef42585ca35e797bc0a2209ff9c5f94f1c59f15f7c3bcb9722bd17261'

# The name of the VM you will create; this doesn't matter at all..
os.environ['kerberosio_server_name'] = 'buildroot.cedricverstraeten.be'

# If you have added an SSH key to DigitalOcean, you can select it
os.environ['kerberosio_ssh_key'] = 'a1:50:01:fd:60:27:62:27:5d:aa:83:b0:c5:54:0c:37'

# Define the id of the image, you'd like to use (e.g. Ubuntu 14)
os.environ['kerberosio_image_id'] = '16724351'

# The location of where to install KiOS on the VM
os.environ['kerberosio_kios_dir'] = '/root/kios/'

# The location on your local workingstation where the images should be stored.
os.environ['kerberosio_release_dir'] = '/Users/cedricverst/Desktop/'

After you've defined the environment variables you can simply run the script and you will have some freshly build KiOs images. Hurray!
