Ignition
Ignition is a utility created to manipulate disks during the initramfs. This includes partitioning disks, formatting partitions, writing files (regular files, systemd units, etc.), and configuring users. On first boot, Ignition reads its configuration from a source of truth (remote URL, network metadata service, hypervisor bridge, etc.) and applies the configuration.
Usage
Odds are good that you don't want to invoke Ignition directly. In fact, it isn't even present in the root filesystem. Take a look at the Getting Started Guide for details on providing Ignition with a runtime configuration.

To help triage or fix bugs, see the current Ignition issues.
Config Validation
To validate a config for Ignition there are binaries for a cli tool called ignition-validate available on the releases page. There is also an ignition-validate container: quay.io/coreos/ignition-validate.
Example:
# This example uses podman, but docker can be used too
podman run --pull=always --rm -i quay.io/coreos/ignition-validate:release - < myconfig.ign
