| * [Hetzner Cloud] (`hetzner`) - Ignition will read its configuration from the instance userdata. Cloud SSH keys are handled separately. | ||
| * [Microsoft Hyper-V] (`hyperv`) - Ignition will read its configuration from the `ignition.config` key in pool 0 of the Hyper-V Data Exchange Service (KVP). Values are limited to approximately 1 KiB of text, so Ignition can also read and concatenate multiple keys named `ignition.config.0`, `ignition.config.1`, and so on. | ||

| +* [IONOS Cloud] (`ionoscloud`) - Ignition will read its configuration from the instance user-data. Cloud SSH keys are handled separately. Per default the user-data is looked up on the root partition in `/var/lib/cloud/seed/nocloud/user-data`. The root partition is detected by the label `ROOT` which can be customized using the environment variable `IGNITION_CONFIG_ROOT_LABEL`. | ||
| * [KubeVirt] (`kubevirt`) - Ignition will read its configuration from the instance userdata via config drive. Cloud SSH keys are handled separately. | ||
| * Bare Metal (`metal`) - Use the `ignition.config.url` kernel parameter to provide a URL to the configuration. The URL can use the `http://`, `https://`, `tftp://`, `s3://`, `arn:`, or `gs://` schemes to specify a remote config. | ||
