Description

    This package allows programatic access to the Kubernetes
    <http://kubernetes.io> rest api.

    Please note this package is still a BETA release (as is kubernetes
    itself), and the methods and API are still subject to change. Use at
    your own risk.

Methods

    By convention, methods will throw exceptions if kubernetes api server
    returns a non-successful status code. Unless otherwise noted, assume
    this behavoir through out.

    new - Create a new $kube object

      All parameters are optional and have some basic default values (where
      appropriate).

      url ['http://localhost:8080']

	The base url for the kubernetes. This should include the protocal
	(http or https) but not "/api/v1beta3" (see base_path).

      base_path ['/api/v1beta3']

	The entry point for api calls, this may be used to set the api
	version with which to interact.

      username

	Username to use with basic authentication. If either username or
	password are not provided, basic authentication will not be used.

      password

	Password to use with basic authentication. If either username or
	password are not provided, basic authentication will not be used.

      token

	An authentication token to be used to access the apiserver. This
	may be provided as a plain string, a path to a file from which to
	read the token (like
	/var/run/secrets/kubernetes.io/serviceaccount/token from within a
	pod), or a reference to a file handle (from which to read the
	token).

 List resources

    These methods retrieve lists (optionally limited by field or label
    selector) of the various resources types kubernetes makes available via
    the API servers rest interface. These methods may also be called on a
    "Namespace" object, which will implicitly limit the result set by
    namespace.

    All of these methods will return an array (or and array ref denpending
    on context) of the approriate resource type
    (Net::Kubernetes::Resource::Pod for example).

    $kube->list_pods([label=>{label=>value}], [fields=>{field=>value}])

    $kube->list_rc([label=>{label=>value}], [fields=>{field=>value}])

    $kube->list_replication_controllers([label=>{label=>value}],
    [fields=>{field=>value}]) (alias to list_rc)

    $kube->list_secrets([label=>{label=>value}], [fields=>{field=>value}])

    $kube->list_services([label=>{label=>value}], [fields=>{field=>value}])

 Create Methods

    These methods may be called either globally or on a namespace object.
    The return value is is an object of the approriate type (determined by
    the "Kind" field)

    my $resource = $kube->create({OBJECT})

    my $resource = $kube->create_from_file(PATH_TO_FILE) (accepts either
    JSON or YAML files)

      Create from file is really just a short cut around something like:

        my $object = YAML::LoadFile(PATH_TO_FILE);
        $kube->create($object);

 Global scoped methods

    These methods are only available at the top level (i.e. not available
    via a namespace object)

    $kube->get_namespace("myNamespace");

      This method returns a "Namespace" object on which many methods can be
      called implicitly limited to the specified namespace.

 Namespace methods

    These methods are accessible only from a name-space object.

    $ns->get_pod('my-pod-name')

    $ns->get_repllcation_controller('my-rc-name') (aliased as
    $ns->get_rc('my-rc-name'))

    $ns->get_service('my-servce-name')

    $ns->get_secret('my-secret-name')

 Resource Methods

    These methods can be called directly on a resource object.

    $resource->delete

    $resource->refresh (update object from api server)

    $resource->update (send local changes to api server)

      This method is only available for resources which have a status
      (currently everything other than secretes).
