	, version: 'v1'
})

// Configure using kubeconfig
var kube = k.kubectl({
	binary: '/bin/kubectl'
	,kubeconfig: '/etc/cluster1.yaml'
	,version: 'v1'
});

kubeAPI

// method GET
kubeapi.get('namespaces/default/replicationcontrollers', function(err, data){})
// method POST
kubeapi.post('namespaces/default/replicationcontrollers', require('./rc/nginx-rc.json'), function(err, data){})
// method PUT
kubeapi.put('namespaces/default/replicationcontrollers/nginx', require('./rc/nginx-rc.json'), function(err, data){})
// method PATCH
kubeapi.patch('namespaces/default/replicationcontrollers/nginx', { apiVersion: 'v1' , spec: { replicas: 2 } }, function(err, data){})
// method DELETE
kubeapi.delete('namespaces/default/replicationcontrollers/nginx', function(err, data){})
// method GET -> watch
kubeapi.watch('watch/namespaces/default/pods', function(data){
	// message
}, function(err){
	// exit
}, [timeout])
