Course Requirements:

1. Laptop (with admin privileges)
2. Desire to Learn.

Module 1: Ansible Basics & Architecture

• Introduction to Ansible: Automation tool for configuration management, application deployment, and orchestration.
• Architecture: Master (control node) and managed nodes (hosts).
• Ansible Components: Inventory, modules, playbooks, and tasks.

---

Module 2: Ansible Playbooks & Variables

• Playbooks: YAML files that define automation tasks.
• Variables: Use variables for dynamic values in playbooks.
  • Declare and use variables in playbooks.
  • Facts: Collect system information during execution.

---

Module 3: Ansible Modules & Collections

• Modules: Core building blocks for tasks (e.g., yum, copy, service).
• Collections: Reusable code packaged together, containing roles, modules, and plugins.

---

Module 4: Ansible Roles, Galaxy & Vault

• Roles: Organize playbooks into reusable units.
• Galaxy: Download and share roles via Ansible Galaxy.
• Vault: Store sensitive data (passwords, keys) securely in playbooks.

---

Module 5: Error Handling & Debugging

• Error Handling: Handle task failures using ignore_errors, when, and block.
• Debugging: Use the debug module to print variable values or task output for troubleshooting.

---

Module 6: Dynamic Inventories, CI/CD Integration

• Dynamic Inventories: Automate host inventory using scripts or cloud plugins (AWS, Azure).
• CI/CD Integration: Automate playbook execution within CI/CD pipelines (e.g., Jenkins, GitLab).

---

Module 7: System Management

• Package Management: Install, update, and remove software (e.g., apt, yum).
• Service Management: Manage system services (start, stop, restart) using Ansible modules.

---

Module 8: End-to-End Project

1. Step 1: Setup Inventory:
   • Create static and dynamic inventories for managed hosts.
2. Step 2: Write Playbooks:
   • Write playbooks for installing a web server (e.g., Nginx or Apache).
   • Use variables for configuration.
3. Step 3: Implement Roles:
   • Organize playbooks into roles (e.g., webserver, database).
   • Download roles from Ansible Galaxy if necessary.
4. Step 4: Use Vault:
   • Securely manage sensitive information (e.g., passwords, API keys).
5. Step 5: Error Handling & Debugging:
   • Handle errors gracefully and use debugging for troubleshooting.
6. Step 6: Integrate with CI/CD:
   • Integrate playbook execution into a CI/CD pipeline (e.g., Jenkins) to deploy applications automatically.
7. Step 7: System Management:
   • Automate system setup tasks, including package installation and service management.
8. Step 8: Final Testing & Deployment:
   • Test the entire setup by executing playbooks and verify the automation pipeline.

Module 9: Final Project

• Automate Multi-Server Deployment:
  • Deploy a multi-tier web application (web server + database).
  • Use Ansible to automate the deployment process, from configuration to maintenance.
  • Implement monitoring and logging, manage servers, and automate updates.
