Several people have popped up in IRC recently with failures in these elements. Without Python 2.7 available in the image they are unsupported (OpenStack hasn't supported it for a long time). Remove these to avoid further confusion. The centos/centos7 DISTRO split that has happened with centos-minimal is unfortunate but I don't think it helps to rename centos7/rhel7 ATM. To summarise; DISTRO=centos7 means image based build, DISTRO=centos && DIB_RELEASE=7 means the minimal build. In the future, I think it is important that the minimal builds and image builds set the same DISTRO. This reflects that "upper" layers shouldn't care about the exact building of the lower layers. I see CentOS 8 going one of two ways 1) the changes are so significant, we start separate centos8 / centos8-minimal elements. They both set DISTRO=centos8 (and DIB_RELEASE to point-release maybe?). This means we have to update all "if DISTRO == centos || DISTRO == centos7" branches to also check for "centos8". Evenually (!) "centos" goes away for versioned DISTRO only 2) we restore centos element with DISTRO=centos and DIB_RELEASE=8, and centos-minimal remains the same. This means we have to audit all "if DISTRO == centos" calls to make sure they're appropriate for version 8 (stick a "&& DIB_RELEASE=7" on them all basically). I'm not sure we can fully decide until we start to see excatly how the distro switching/matching bits look, but (2) is consistent with Ubuntu and probably the preferred solution. Some "rhel" parts have been cleaned up. More could be done in rhel-common, but given our lack of coverage of that I'd prefer to leave it for now. Change-Id: I6ea784116ef59ca22878c8512c963f29c815a00a
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. - 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.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
