Prepare a physical machine image¶

If you use default Fuel drivers for Ironic, you must build and upload a physical machine image into Glance, as well as configure the image with specific parameters.

To prepare a physical machine image:

1. Build a physical machine image.

   You can build images for a physical machine using a method of your personal preference. For example, using Disk Image builder (DIB):

   disk-image-create -a amd64 -p <packages> -o <image_name> <base_image>
   

   Example:

   disk-image-create -a amd64 -p grub2-common,grub-pc, \
   grub-gfxpayload-lists,emacs24-nox,parted baremetal ubuntu-minimal
   

2. Upload the image to Glance using the glance image-create command.

   Example:

   glance image-create --name test --disk-format raw --container-format bare
             --file test [--visibility public]
   

3. Tag the image with the corresponding metadata.

   Example:

   glance image-update <image-id> --property cpu_arch=x86_64
                                  --property hypervisor_type="baremetal"
                                  --property fuel_disk_info=DISK_INFO
   

   The DISK_INFO value is a structure that describes the partition layout required by the image.

   Example:

   ‘[{"name": "sda", "extra": [], "free_space": 11000, "type": "disk",
   "id": "vda", "size": 11000, "volumes": [{"mount": "/", "type":
   "partition", "file_system": "ext4", "size": 10000}]}]’
   

   Warning

   Only extended file systems are supported!
