# This playbook installs kubernetes on the local host for development purposes
# only. This assumes there is a local docker daemon running, and that docker
# doesn't use the latest "overlay2" filesystem driver (which kubernetes doesn't
# support).
#
# Should work on Ubuntu 16.04, in theory, and was tested on 17.04.
