General CoreOS Pre-Installation Notes:

• Ensure that the bin_dir is set to /opt/bin
• ansible_python_interpreter should be /opt/bin/python. This will be laid down by the bootstrap task.
• The default resolvconf_mode setting of docker_dns does not work for CoreOS. This is because we do not edit the systemd service file for docker on CoreOS nodes. Instead, just use the host_resolvconf mode. It should work out of the box.

Then you can proceed to cluster deployment
