coreos-installer

coreos-installer is a program to assist with installing Fedora CoreOS (FCOS) and Red Hat Enterprise Linux CoreOS (RHCOS). It can do the following:

• Install the operating system to a target disk, optionally customizing it with an Ignition config or first-boot kernel parameters (coreos-installer install)
• Download and verify an operating system image for various cloud, virtualization, or bare metal platforms (coreos-installer download)
• List Fedora CoreOS images available for download (coreos-installer list-stream)
• Embed an Ignition config in a live ISO image to customize the running system that boots from it (coreos-installer iso ignition)
• Wrap an Ignition config in an initrd image that can be appended to the live PXE initramfs to customize the running system that boots from it (coreos-installer pxe ignition)

The options available for each subcommand are available in the Command Line Reference or via the --help option.
