Usage Examples

Quick Status Check

ansible-playbook -i hosts.ini playbooks/service_status.yml --limit homelab -e "collect_all=true"

Collect Logs for Troubleshooting

ansible-playbook -i hosts.ini playbooks/container_logs.yml --limit homelab -e "service_pattern=prometheus log_lines=200"

Safe Service Restart

ansible-playbook -i hosts.ini playbooks/restart_service.yml --limit homelab -e "service_name=grafana"

Backup All Databases

ansible-playbook -i hosts.ini playbooks/backup_databases.yml -e "retention_days=30"

Next Steps

Pending Tasks

1. System Monitoring Playbooks: Create system health and disk usage monitoring
