Ansible Event-Driven Automation (EDA) Rulebook Skill

Create comprehensive Event-Driven Ansible rulebooks that respond to events from various sources, enabling automated infrastructure response and self-healing systems.

What is Ansible Event-Driven Automation?

Ansible EDA enables event-driven automation by listening for events from various sources and automatically executing Ansible content in response.

Key Components:

• Rulebooks: YAML files defining event sources, conditions, and actions
• Event Sources: Plugins that listen for events (webhooks, Kafka, alerts, etc.)
• Conditions: Patterns to match specific events
• Actions: Automated responses (run playbooks, modules, job templates)
• ansible-rulebook: CLI tool for running rulebooks
• EDA Controller: Enterprise platform for managing EDA at scale

Use Cases:

• Incident response and remediation
• Self-healing infrastructure
• Security event response
• CI/CD pipeline integration
• Alert-driven automation
• Application monitoring response
• Network event handling
• IoT device management

Installation

# Install ansible-rulebook
pip install ansible ansible-rulebook

# Install event source plugins
ansible-galaxy collection install ansible.eda

# Verify installation
ansible-rulebook --version

# Optional: Install Java for some event sources (Kafka, etc.)
sudo dnf install java-11-openjdk  # RHEL/Fedora
sudo apt-get install openjdk-11-jre  # Ubuntu/Debian

Rulebook Structure

Basic Rulebook Anatomy

---
- name: Rulebook Name
  hosts: all  # or specific host group
  sources:
    - ansible.eda.webhook:
        host: 0.0.0.0
        port: 5000
  
  rules:
    - name: Rule Name
      condition: event.payload.status == "critical"
      action:
        run_playbook:
          name: remediate.yml

Required Fields:

• name: Descriptive rulebook name
• hosts: Target hosts (like playbooks)
• sources: List of event source plugins
• rules: List of rules with conditions and actions
