We are currently having issues being able to generate proper module option documentation for our recursive disko types. However you can read the available options here. Combined with the examples this hopefully gives you an overview.
Usage: ./disko [options] disk-config.nix
or ./disko [options] --flake github:somebody/somewhere#disk-config
With flakes, disk-config is discovered first under the .diskoConfigurations top level attribute
or else from the disko module of a NixOS configuration of that name under .nixosConfigurations.
Options:
* -m, --mode mode
set the mode, either format, mount or disko
format: create partition tables, zpools, lvms, raids and filesystems
mount: mount the partition at the specified root-mountpoint
disko: first unmount and destroy all filesystems on the disks we want to format, then run the create and mount mode
* -f, --flake uri
fetch the disko config relative to this flake's root
* --arg name value
pass value to nix-build. can be used to set disk-names for example
* --argstr name value
pass value to nix-build as string
* --root-mountpoint /some/other/mnt
where to mount the device tree (default: /mnt)
* --dry-run
just show the path to the script instead of running it
* --no-deps
avoid adding another dependency closure to an in-memory installer
requires all necessary dependencies to be available in the environment
* --debug
run with set -x
