Kubelet
=======

Configuration for the Kubernetes worker daemon (the Kubelet).  This document
contains three keys: ``arguments``, ``images``, and ``config_file_overrides``.
The ``arguments`` are appended directly to the ``kubelet`` command line,
along with arguments that are controlled by Promenade more directly.
The ``config_file_overrides`` are appended directly to the static kubelet
configuration file and only consists of a subset of kubelet arguments.
More information regarding the format for this key can be found here_.

The only image that is configurable is for the ``pause`` container.
