Configuration

storage type

Contains the options for provisioning disks, partitions, and file systems.

Example:

storage:
  bootType: efi

  disks:
  - partitionTableType: gpt
    maxSize: 4G
    partitions:
    - id: esp
      type: esp
      size: 8M

    - id: rootfs
      size: grow

  filesystems:
  - deviceId: esp
    type: fat32
    mountPoint:
      path: /boot/efi
      options: umask=0077

  - deviceId: rootfs
    type: ext4
    mountPoint: /

os:
  bootloader:
    resetType: hard-reset

bootType [string]

Specifies the boot system that the image supports.

Supported options:

• legacy: Support booting from BIOS firmware.

  When this option is specified, the partition layout must contain a partition with the bios-grub flag.

• efi: Support booting from UEFI firmware.

  When this option is specified, the partition layout must contain a partition with the esp flag.

Example:

storage:
  disks:
  - partitionTableType: gpt
    partitions:
    - id: boot
      type: bios-grub
      size: 8M

    - id: rootfs
      size: 4G

  bootType: legacy

  filesystems:
  - deviceId: rootfs
    type: ext4
    mountPoint: /

os:
  bootloader:
    resetType: hard-reset

disks [disk[]]

Contains the options for provisioning disks and their partitions.

Note: While disks is a list, only 1 disk is supported at the moment. Support for multiple disks may (or may not) be added in the future.

verity [verity[]]

Configure verity block devices.

filesystems [filesystem[]]

Specifies the mount options of the partitions.

resetPartitionsUuidsType [string]

Specifies that the partition UUIDs and filesystem UUIDs should be reset.

Value is optional.

This value cannot be specified if storage is specified (since customizing the partition layout resets all the UUIDs anyway).

If this value is specified, then os.bootloader.resetType must also be specified.

Supported options:

• reset-all: Resets the partition UUIDs and filesystem UUIDs for all the partitions.

Example:

storage:
  resetPartitionsUuidsType: reset-all

os:
  bootloader:
    resetType: hard-reset
