This code repository contains examples from the video course Ansible 2 for Configuration Management by Alan Hohn, published by Packt Publishing.

This repository is laid out based on the course videos. The first video after the course introduction includes a complete Ansible demo, so the section-1/video-1.2 folder contains a complete example of using Ansible to install and configure software on a set of servers.

See the section-1/video-1.3 folder for instructions on installing Ansible. Then, install required roles using Ansible Galaxy:

ansible-galaxy install geerlingguy.java,1.9.5
ansible-galaxy install geerlingguy.elasticsearch,3.0.1
ansible-galaxy install geerlingguy.kibana,3.2.1
ansible-galaxy install geerlingguy.logstash,4.0.0

Finally, many of the course examples are configured to run Ansible against three virtual machines in Amazon Web Services. See the setup folder for creating these virtual machines using Ansible.

All of these prerequisites are needed before running the complete example in section-1/video-1.2.

Once the virtual machines are created in Amazon Web Services, Ansible dynamic inventory is used to find the instances and obtain IP addresses. The common folder contains the standard ec2 dynamic inventory script ec2.py and configuration file ec2.ini. The ec2.ini file is configured to use the U.S. East 1 AWS region; if you wish to use another region, edit this file (and update the associated variables in the setup/group_vars/all.yaml file).

Of course, using what you learn from these videos, you can also adapt these examples to use regular static inventory to control other physical or virtual machines.
