disk-image-create [-a i386|amd64|armhf|arm64] -o filename {element} [{element} …]

Create an image of element {element}, optionally mixing in other elements. Element dependencies are automatically included. Support for other architectures depends on your environment being able to run binaries of that platform and/or packages being available for the architecture. For instance, to enable armhf on Ubuntu install the qemu-user-static package, or to enable arm64 on CentOS setup the RDO aarch64 package repositories. The default output format from disk-image-create is qcow2. To instead output a tarball pass in “-t tar”. This tarball could then be used as an image for a linux container(see docs/docker.md).

ramdisk-image-create -o filename {element} [{element} …]

Create a kernel+ ramdisk pair for running maintenance on bare metal machines (deployment, inventory, burnin etc).

To generate kernel+ramdisk pair for use with nova-baremetal, use:

ramdisk-image-create -o deploy.ramdisk deploy-baremetal

Ironic no longer supports images created like this.

element-info

Extract information about elements.

tests/run_functests.sh

This runs a set of functional tests for diskimage-builder.

elements can be found in the top level elements directory.
