# Ignition Provider
The Ignition provider is used to generate [Ignition](https://coreos.com/ignition/docs/latest/) configuration files. _Ignition_ is the provisioning utility used by [CoreOS](https://coreos.com/) Linux.
The ignition provider is what we call a _logical provider_ and doesn't manage any _physical_ resources. It generates configurations files to be used by other resources.
Use the navigation to the left to read about the available resources.
## Example Usage
This config will write a single service unit (shown below) with the contents of an example service. This unit will be enabled as a dependency of multi-user.target and therefore start on boot
```
# Systemd unit resource containing the unit definition
resource "ignition_systemd_unit" "example" {
