Prerequisites
It is assumed that participants are working systems administrators, developers, and/or testers with some very basic scripting knowledge (bash, ksh, Perl or Python) and have an understanding of fundamental system utilities/commands on Linux and Windows systems.
Outline
Introduce Ansible
Describe the terminology and architecture of Ansible.
Deploy Ansible
Configure Ansible and run ad hoc commands.
Implement playbooks
Write Ansible plays and execute a playbook.
Manage variables and inclusions
Describe variable scope and precedence, manage variables and facts in a play, and manage inclusions.
Implement task control
Manage task control, handlers, and tags in Ansible playbooks.
Implement Jinja2 templates
Employ a Jinja2 template.
Implement roles
Create and manage roles.
Configure complex playbooks
Learn and replicate how Ansible executes plays and tasks using host patterns, delegation, and parallelism.
Implement Ansible Vault
Manage encryption with Ansible Vault.
Troubleshoot Ansible
Troubleshoot the Ansible control machine and managed nodes.
Install Ansible Tower and describe Ansible Tower's architecture
Explain what Ansible Tower is and demonstrate a basic ability to navigate and use its web user interface.
Create users and teams for role-based access control
Create user accounts and organize them into teams that can be used in conjunction with role-based access control to manage administration and access to organizational resources in Ansible Tower.
Create and manage inventories and credentials
Build inventories of machines to manage and set up credentials that will allow Ansible Tower to run jobs on those systems.
Manage projects for provisioning with Ansible Tower
Create basic projects and job templates in Ansible Tower that can be used to run Ansible playbooks in order to provision and configure managed systems.
Construct advanced job workflows
Use additional features of job templates to improve workflows by creating simple job launch forms and templates to launch multiple jobs in sequence, and also to report job success or failure through external notification systems.
Update inventories dynamically and compare inventory members
Use advanced techniques to work with inventories, including dynamic generation of inventories from centralized information sources and monitoring of hosts in an inventory for configuration deviations or differences.
Maintenance and administration of Ansible Tower
Perform routine maintenance and administration on Ansible Tower and establish a basic familiarity with the command line tools and the Ansible Tower API.
