Course Outline
1 Developing playbooks with Ansible Automation Platform
- The roles of automation controller, automation hub, platform gateway and execution environments.
- Preparing developer tools, including Git, the Ansible extension for VS Code and ansible-lint.
- Running playbooks with ansible-navigator in interactive and stdout modes.
- Managing project files in Git using branches, commits, pushes and pulls.
- Structuring playbooks, roles and projects for readability, reuse and maintenance.
2 Using content collections and execution environments
- Collection namespaces, fully qualified collection names and content dependencies.
- Finding collections in Red Hat automation hub, private automation hub and Ansible Galaxy.
- Installing required collections with ansible-galaxy and requirements files.
- Selecting an execution environment and inspecting the tools and collections it contains.
- Understanding collection availability inside execution environments and through project content paths.
3 Running playbooks through automation controller
- Using the unified platform interface to manage and launch automation.
- The relationships between organisations, projects, inventories, credentials and job templates.
- Connecting Git-based automation projects and selecting execution environments.
- Launching jobs and interpreting output, status and execution errors.
4 Configuring Ansible and automation content navigator
- How Ansible locates configuration files and applies environment-variable overrides.
- Inspecting effective settings with ansible-config and ansible-navigator config.
- Configuring execution environment images, pull behaviour, execution mode and logging in ansible-navigator.yml.
- Diagnosing configuration differences that affect playbook development and execution.
5 Managing inventories and inventory variables
- Creating YAML inventories and converting existing INI inventory structures.
- Organising host and group variables in host_vars and group_vars directories.
- Using host aliases and connection variables such as ansible_host, ansible_user and ansible_connection.
- Generating inventory data through dynamic inventory plug-ins.
- Combining inventory sources and checking the resulting hosts, groups and variables.
6 Controlling and optimising task execution
- Managing privilege escalation with become at appropriate playbook levels.
- Understanding execution order across pre_tasks, roles, tasks, handlers and post_tasks.
- Controlling handlers with notify, listen and meta: flush_handlers.
- Selecting tasks with tags, including the special always and never tags.
- Reviewing performance using fact-gathering settings, caching, forks, SSH pipelining and callback plug-ins.
7 Transforming data with filters and plug-ins
- Applying Jinja2 filters to strings, lists, dictionaries, defaults and data types.
- Retrieving external data with lookup plug-ins and query.
- Processing structured data with loops, subelements, dict2items, product and loop_control.
- Working with network-address data through ansible.utils.ipaddr filters.
- Preparing variables in the formats expected by reusable roles and templates.
8 Coordinating rolling updates
- Delegating tasks and facts with delegate_to and delegate_facts, including local actions.
- Controlling parallel execution and host batches with forks and serial.
- Using max_fail_percentage and any_errors_fatal to control the response to failures.
- Understanding how run_once behaves when updates are performed in batches.
- Coordinating host removal from and return to a load balancer to minimise disruption during updates.
9 Creating collections and custom execution environments
- Organising collection content, including roles, modules, plug-ins and supporting metadata.
- Defining collection metadata and compatibility information in galaxy.yml and meta/runtime.yml.
- Building collection packages and publishing them to private automation hub.
- Defining dependencies in execution-environment.yml and building images with ansible-builder.
- Validating custom environments with ansible-navigator and using them with automation controller.
Requirements

- RHCE certification on Red Hat Enterprise Linux 9 or later, or equivalent Ansible knowledge and skills.
- Ability to work at the Linux command line, read and write YAML, and create basic Ansible playbooks.
- Familiarity with Git repositories and basic version-control operations.
