RHCE – Red Hat Certified Engineer

Module 1: Introduction to RHCE and Ansible

• RHCE exam overview: EX294 – Ansible automation focus
• Ansible fundamentals: agentless automation with SSH and Python
• Ansible architecture: control node, managed nodes, inventory, and playbooks
• Installing Ansible: on RHEL and configuring ansible.cfg

Module 2: Ansible Inventory and Ad-Hoc Commands

• Inventory files: static inventory with groups and host variables
• Dynamic inventory: scripts and plugins for cloud inventory
• Ad-hoc commands: ansible -m module for quick tasks
• Common modules: ping, command, shell, copy, and file

Module 3: Ansible Playbooks

• Playbook structure: plays, tasks, and modules in YAML
• Variables: vars, vars_files, and group_vars/host_vars
• Facts: using ansible_facts for dynamic configuration
• Handlers: triggering actions on task state change

Module 4: Ansible Roles

• Role structure: tasks, handlers, vars, defaults, files, and templates
• Creating roles: ansible-galaxy init and role directory layout
• Using roles in playbooks: roles keyword and include_role
• Ansible Galaxy: downloading and using community roles

Module 5: Jinja2 Templates and Conditionals

• Jinja2 templates: dynamic file generation with variables
• when: conditionals based on facts and registered variables
• loop and with_items: iterating over lists and dictionaries
• register: capturing task output for use in subsequent tasks

Module 6: Ansible Vault and Security

• Ansible Vault: encrypting sensitive variables and files
• vault-id: managing multiple vault passwords
• Best practices: separating encrypted and plain variable files
• Privilege escalation: become, become_user, and sudo configuration

Module 7: Advanced Ansible

• Tags: selectively running portions of playbooks
• Error handling: ignore_errors, failed_when, and block/rescue/always
• Delegation: running tasks on a different host with delegate_to
• Asynchronous tasks: long-running tasks with async and poll

Module 8: Capstone Project and Assessment

• Ansible inventory: static and dynamic inventory configuration
• Playbook: multi-play automation for web server and DB configuration
• Role development and Ansible Vault encryption project
• Final assessment and course certification

Experience in the Industry Gain expertise from Red Hat-certified engineers who have automated Linux infrastructure configuration, application deployment, and compliance enforcement using Ansible across enterprise environments.

Backgrounds at the Top Our RHCE trainers have worked at Red Hat partner organisations and enterprise automation teams using Ansible to manage hundreds of RHEL servers with repeatable, auditable automation playbooks.

Clear & Effective Teaching Ansible architecture, inventory, ad-hoc commands, playbooks, roles, Jinja2 templates, Ansible Vault, error handling, and advanced automation features are explained with real infrastructure automation examples aligned to RHCE EX294.

Hands-On Learning Focus Students write Ansible playbooks, build reusable roles, use Jinja2 templates, encrypt secrets with Vault, implement error handling, and automate multi-tier server configurations through structured hands-on Ansible labs.

Up-to-Date Knowledge Trainers keep content current with the latest Ansible and Red Hat Ansible Automation Platform releases, RHCE EX294 exam updates, and evolving infrastructure automation best practices.
