Overview

This module at present install a kubernetes master and minion. it is still heavily in development as at present should only be used on CentOS 7 unless one wishes to add their own repos

Module Description

Will add a basic minion/master on a series of CentOS 7 Boxes

Setup

Example master setup

node 'master'{

    class {'kubernetes::master':
      master_name => '173.16.32.11', #can be hostname if dns setup
      minion_name => ['173.16.32.12','173.16.32.12'], #can be hostname if dns setup
    }
    contain 'kubernetes'
}

Example minion setup

node 'minion'{

    class {'kubernetes::minion':
      master_name => '173.16.32.11', #can be hostname if dns setup
      minion_name => '173.16.32.12', #can be hostname if dns setup
    }
    contain 'kubernetes'
}

These values can also be specified in hiera

For a master

---
  kubernetes::master_name: '173.16.32.11'
  kubernetes::minion_name:  ['173.16.32.12']

For minions

---
  kubernetes::master_name: '173.16.32.11'
  kubernetes::minion_name:  '173.16.32.12'

What kubernetes affects

kubernetes will install a kube master if kubernetes::master class is called, else it will add a minion if kubernetes::minion is called

Setup Requirements OPTIONAL

Be sure epel is enabled, if you do not have epel you will need to yum install epel-release none as yet but std lib will be needed soon

Beginning with kubernetes

I have tested this on CentOS 7 since epel has all of the rpms you will need (once epel is enabled), no additional packages should be needed. As yet I have not tied down the ordering , this will follow.

Usage

Example master setup

node 'master'{

    class {'kubernetes::master':
      master_name => '173.16.32.11', #can be hostname if dns setup
      minion_name => ['173.16.32.12','173.16.32.12'], #can be hostname if dns setup
    }
    contain 'kubernetes'
}

Example minion setup

node 'minion'{

    class {'kubernetes::minion':
      master_name => '173.16.32.11', #can be hostname if dns setup
      minion_name => '173.16.32.12', #can be hostname if dns setup
    }
    contain 'kubernetes'
}

Reference

classes as follows:

kubernetes
kubernetes::master
kubernetes::minion

Limitations

This should not be considered a production release it is far too young and undeveloped. Nonetheless it can be used as a guide. I would suggest testing this with vagrant.

Development

I welcome any input since we have very few kubernetes modules
