Nova provides a mechanism to set static vendordata via a file [1]. This patch provides support in Kolla Ansible for using this feature. Arguably this could be part of a generic mechansim for copying arbitrary config, but: - It's not clear if there is anything else that would take advantage of this - One size might not fit all [1] https://docs.openstack.org/nova/latest/configuration/config.html#api.vendordata_jsonfile_path Change-Id: Id420376d96d0c40415c369ae8dd36e845a781820

Nova - Compute Service
Nova is a core service in OpenStack, and provides compute services. Typically this is via Virtual Machines (VMs), but may also be via bare metal servers if Nova is coupled with Ironic.
Nova is enabled by default, but may be disabled by setting
enable_nova to no in
globals.yml.
Virtualisation Drivers
The virtualisation driver may be selected via
nova_compute_virt_type in globals.yml.
Supported options are qemu, kvm, and
vmware. The default is kvm.
Libvirt
Information on the libvirt-based drivers kvm and
qemu can be found in libvirt-guide.
VMware
Information on the VMware-based driver vmware can be
found in vmware-guide.
Bare Metal
Information on using Nova with Ironic to deploy compute instances to
bare metal can be found in ../bare-metal/ironic-guide.
Fake Driver
The fake driver can be used for testing Nova's scaling properties
without requiring access to a large amount of hardware resources. It is
covered in nova-fake-driver.
Consoles
The console driver may be selected via nova_console in
globals.yml. Valid options are none,
novnc and spice. Additionally, serial console
support can be enabled by setting
enable_nova_serialconsole_proxy to yes.
Cells
Information on using Nova Cells V2 to scale out can be found in nova-cells-guide.
Vendordata
Nova supports passing deployer provided data to instances using a
concept known as Vendordata. If a Vendordata file is located in the
following path within the Kolla configuration, Kolla will automatically
use it when the Nova service is deployed or reconfigured:
/etc/kolla/config/nova/vendordata.json.
