Opleiding: Ansible Configuration Management

Ansible Architectuur

The course starts with an explanation of Ansible's multi-tier architecture that does not describe just one system, but how all systems are interrelated. Ansible does not use agents but connects to the nodes via SSH or other protocol and puts code in the form of Ansible Modules on the nodes to execute.

YAML Syntax

Next the YAML syntax is discussed. It is explained how Ansible groups the hosts with YAML in the hosts files. The joint hosts files then form the Ansible inventory.

Ansible Playbooks

Also attention is paid to Ansible playbooks that describe the commands, modules and tasks that are executed on a specific group of hosts from hosts files.

Task Automation

The precise details of automating tasks are also part of the course program. The parallelization of tasks, loops and conditional execution are treated and the use of environment variables is discussed as well.

Advanced Ansible

Finally attention is paid to a number of Ad-hoc Ansible commands such as shell commands and commands for managing files and directories and Advanced Ansible topics such as Playbook Includes, Custom Modules and Plugins are discussed.
