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
Will add a basic minion/master on a series of CentOS 7 Boxes
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'
kubernetes will install a kube master if kubernetes::master class is called, else it will add a minion if kubernetes::minion is called
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
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.
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'
}
classes as follows:
kubernetes
kubernetes::master
kubernetes::minion
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.
I welcome any input since we have very few kubernetes modules
