On your control node, change to the directory; /home/studentnn/lightbulb/workshops/ansible_engine/simple_playbook/resources (please note you will need to specify the correct user under the home directory)
To change directories, type;
$ cd /home/studentnn/lightbulb/workshops/ansible_engine/simple_playbook/resources
Verify the index.html file is present by typing; ls
On your control node open an editor (such as vi or nano) and create the following ansible playbook (be sure to start with the 3 dashes in the first line);
You may need to run your editor as sudo - i.e. sudo vi simple_playbook.yml

Verify nginx has been installed by testing one of your nodes. Open a browser on your laptop and point to the public IP address of one of your nodes (not the control node).
i.e. http://34.229.6.4
If successful, you should see a web page with the Ansible logo.
