# 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 data resource containing the unit definition
|
|
data "ignition_systemd_unit" "example" {
|
|
name = "example.service"
|
|
content = "[Service]\nType=oneshot\nExecStart=/usr/bin/echo Hello World\n\n[Install]\nWantedBy=multi-user.target"
|
|
}
|
|
|
|
# Ingnition config include the previous defined systemd unit data resource
|
|
data "ignition_config" "example" {
|
|
systemd = [
|
|
"${data.ignition_systemd_unit.example.id}",
|
|
]
|
|
}
|
|
|
|
# Create a CoreOS server using the Igntion config.
|
|
resource "aws_instance" "web" {
|
|
# ...
|
|
|
|
user_data = "${data.ignition_config.example.rendered}"
|
|
}
|
|
```
