r"""Check_MK Agent Plugin: mk_docker.py

This plugin is configured using an ini-style configuration file,
i.e. a file with lines of the form 'key: value'.
At 'agents/cfg_examples/mk_docker.cfg' (relative to the check_mk
source code directory ) you should find some example configuration
files. For more information on possible configurations refer to the
file docker.cfg in said directory.
The docker library must be installed on the system executing the
plugin ("pip install docker").

This plugin it will be called by the agent without any arguments.

Hi,
you have to use the correct docker plugin for Checkmk 1.6. This can be found in the site directory: share/check_mk/agents/plugins. But I think @andreas-doehler told you this already:
