kubernetes

This module installs and configures a kubernetes clutser.

The main class kubernetes it only populates the /etc/kubernetes/config file.

Because of this, it needs to be forced to execute after the master or node has installed any programs (the file is created by both master or node). This is accomplished by forcing this in the node and master class.

The class kubernetes::client doesn't do anything now.

Usage:

  include kubernetes
  include kubernetes::master
  include kubernetes::node
  include kubernetes::node::kubelet
  include kubernetes::node::kube_proxy

  class { 'kubernetes::master::apiserver':
    admission_control             => [
      'NamespaceLifecycle',
      'NamespaceExists',
      'LimitRanger',
      'SecurityContextDeny',
      'ResourceQuota',
      ],
  }

If you want to use you existing network infrastructure, then wou will have to allocate to nodes a subnet from the same ip class. You can self register a node with this information by giving kubelet_register_node = > true and the desired subnet in kubelet_pod_cidr:

	class { 'kubernetes::node::kubelet':
	  ensure                  => 'latest',
	  address                 => '0.0.0.0',
	  api_servers             => 'http://k-api.company.net:8080',
	  configure_cbr0          => true,
	  register_node           => true,
	  pod_cidr                => '10.100.5.0/24',
	}
