Ansible
Agentless automation that applies configuration over SSH from playbooks and roles.
The problem it solves
Agentless automation that applies configuration over SSH from playbooks and roles.
Technical rationale
Ansible owns what happens inside a machine, which is exactly where Terraform loses visibility. I write roles so a second run against an already-configured host changes nothing, and I keep the inventory derived from Terraform output: a hand-written list goes stale without warning and leaves machines no playbook reaches.
How I have used it
It configures everything that happens inside a homelab host or guest, with the inventory regenerated from Terraform output.
