Supported Platforms

Ignition is currently only supported for the following platforms:

  • Bare Metal - Use the coreos.config.url kernel parameter to provide a URL to the configuration. The URL can use the http:// or tftp:// schemes to specify a remote config or the oem:// scheme to specify a local config, rooted in /usr/share/oem.
  • PXE - Use the coreos.config.url and coreos.first_boot=1 (in case of the very first PXE boot only) kernel parameters to provide a URL to the configuration. The URL can use the http:// or tftp:// schemes to specify a remote config or the oem:// scheme to specify a local config, rooted in /usr/share/oem.
  • Amazon EC2 - Ignition will read its configuration from the instance userdata. SSH keys are handled by coreos-metadata.
  • Microsoft Azure - Ignition will read its configuration from the custom data provided to the instance. SSH keys are handled by the Azure Linux Agent.
  • VMware - Use the VMware Guestinfo variables coreos.config.data and coreos.config.data.encoding to provide the config and its encoding to the virtual machine. Valid encodings are "", "base64", and "gzip+base64". Guestinfo variables can be provided directly or via an OVF environment, with priority given to variables specified directly.
  • Google Compute Engine - Ignition will read its configuration from the instance metadata entry named "user-data". SSH keys are handled by coreos-metadata.
  • Packet - Ignition will read its configuration from the instance userdata. SSH keys are handled by coreos-metadata.
  • QEMU - Ignition will read its configuration from the 'opt/com.coreos/config' key on the QEMU Firmware Configuration Device.
  • DigitalOcean - Ignition will read its configuration from the droplet userdata. SSH keys and network configuration are handled by coreos-metadata.
  • Oracle Cloud - Ignition will read its configuration from the instance userdata. SSH keys are handled by coreos-metadata.

Ignition is under active development so expect this list to expand in the coming months.
