This element is deprecated and copied to ironic-python-agent-builder and can be found at: https://opendev.org/openstack/ironic-python-agent-builder/src/branch/master/dib/ironic-python-agent-ramdisk The ramdisk can be build from the ironic-python-agent-builder and the “ironic-element” in diskimage-builder is deprecated.
Beyond installing the ironic-python-agent, this element does the following:
Installs the dhcp-all-interfaces
so the node, upon booting, attempts to
obtain an IP address on all available network interfaces.
Disables the iptables
service on SysV and systemd based systems.
Disables the ufw
service on Upstart based systems.
qemu-utils
parted
hdparm
util-linux
genisoimage
When installing from source, python-dev
and gcc
are also installed
in order to support source based installation of ironic-python-agent and its
dependencies.
Install the certificate if any, which is set to the environment variable
DIB_IPA_CERT
for validating the authenticity by ironic-python-agent. The
certificate can be self-signed certificate or CA certificate.
Compresses initramfs with command specified in environment variable
DIB_IPA_COMPRESS_CMD
, which is ‘gzip’ by default. This command should listen
for raw data from stdin and write compressed data to stdout. Command can be
with arguments.
This element outputs three files:
$IMAGE-NAME.initramfs
: The deploy ramdisk file containing the
ironic-python-agent (IPA) service.
$IMAGE-NAME.kernel
: The kernel binary file.
$IMAGE-NAME.vmlinuz
: A hard link pointing to the $IMAGE-NAME.kernel
file; this is just a backward compatibility layer, please do not rely
on this file.
Note
The package based install currently only enables the service when using the systemd init system. This can easily be changed if there is an agent package which includes upstart or sysv packaging.
Note
Using the ramdisk will require at least 1.5GB of ram
