Ian Wienand 18a0d970fa Move ironic-agent test to fedora-minimal
I'm uncertain as to why this is using the "fedora" element for testing
... but it requires downloading the fedora .qcow on every test which
has shown to be unreliable.  An easy thing to do is to switch it to
fedora-minimal; that will only involve downloads from local mirrors in
the gate.

Add redhat-rpm-config for minimal.  I admit I have not fully gone
through why this is not pulled in.  It's been an issue since
I459f2203fa145049dda185da952813118193d573 and there's all sorts of
bugs.

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.

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
