ironic-agent¶

Builds a ramdisk with ironic-python-agent. More information can be found at:

https://git.openstack.org/cgit/openstack/ironic-python-agent/

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.

• Installs packages required for the operation of the ironic-python-agent::

  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.
