# Example .vmdb file

A .vmdb file defines how an image is built:

    steps:
      - mkimg: "{{ output }}"
        size: 4G

      - mklabel: msdos
        device: "{{ output }}"

      - mkpart: primary
        device: "{{ output }}"
        start: 1M
        end: 10M
        tag: unused

      - mkpart: primary
        device: "{{ output }}"
        start: 10M
        end: 100%
        tag: rootfs

      - kpartx: "{{ output }}"

      - mkfs: ext4
        partition: rootfs
        label: smoke

      - mount: rootfs

      - unpack-rootfs: rootfs

      - debootstrap: stretch
        mirror: http://deb.debian.org/debian
        target: rootfs
        unless: rootfs_unpacked

      - apt: install
        packages:
          - linux-image-amd64
        tag: rootfs
        unless: rootfs_unpacked

      - cache-rootfs: rootfs
        unless: rootfs_unpacked

      - chroot: rootfs
        shell: |
          sed -i '/^root:[^:]*:/s//root::/' /etc/passwd
          echo pc-vmdb2 > /etc/hostname

      - grub: bios
        tag: rootfs
        console: serial
