"ironic-agent" element is currently removing sudo, which breaks other elements such as devuser. There appears to be no security or other reason to do this, it's just the way it has always been. Leave sudo in as it is considered part of the base cloud images. Change-Id: Ida9b1885f745146071e4b2d85ae59341ac85d5c8 Closes-Bug: #1572486
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-interfacesso the node, upon booting, attempts to obtain an IP address on all available network interfaces. - Disables the
iptablesservice on SysV and systemd based systems. - Disables the
ufwservice on Upstart based systems. - Installs packages required for the operation of the ironic-python-agent::
-
qemu-utilspartedhdparmutil-linuxgenisoimage
- When installing from source,
python-devandgccare 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_CERTfor validating the authenticity by ironic-python-agent. The certificate can be self-signed certificate or CA certificate.
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.kernelfile; 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
