Harald Jensås ace5bbf3f4 dhcp-all-interfaces: let NetworkManager doit. 
Override the default for DIB_DHCP_NETWORK_MANAGER_AUTO
to `true` on RHEL and CentOS release 8 and later.

The dhcp-all-interfaces element is configured to only
apply NetworkManager configuration. The service:
dhcp-all-interfaces will not be enabled. Not enabling the
service allows NetworkManager to do the interface auto-
configuration. In release 8 and later it should do this
just as good, or even better, compared to the
dhcp-all-interfaces.sh script.

ironic-python-agent-ramdisk

Builds a ramdisk with ironic-python-agent.

More information can be found at: https://docs.openstack.org/ironic-python-agent/latest/

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.
  • Configures rescue mode if DIB_IPA_ENABLE_RESCUE is not set to false.

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.

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
