What are Ansible handlers? 🤔
If you're asking why your Ansible playbook restarts services every time—even when nothing changes—you need to understand handlers. In this video, we break down exactly what Ansible handlers are, how they work, and when to use them. You'll get real-time demos, 5 practical use cases, and common mistakes to avoid.
This clip is taken straight from our Ansible Essentials course on Alta3 Academy!
