Role - metalsmith_deployment¶

This role deploys instances using metalsmith CLI.

Variables¶

The only required variable is:

metalsmith_instances: list of instances to provision, see Instance for instance description.

The following optional variables provide the defaults for Instance attributes:

metalsmith_candidates: the default for candidates.
metalsmith_capabilities: the default for capabilities.
metalsmith_conductor_group: the default for conductor_group.
metalsmith_extra_args: the default for extra_args.
metalsmith_image: the default for image.
metalsmith_image_checksum: the default for image_checksum.
metalsmith_image_kernel: the default for image_kernel.
metalsmith_image_ramdisk: the default for image_ramdisk.
metalsmith_netboot: the default for netboot
metalsmith_nics: the default for nics.
metalsmith_resource_class: the default for resource_class.
metalsmith_root_size: the default for root_size.
metalsmith_ssh_public_keys: the default for ssh_public_keys.
metalsmith_swap_size: the default for swap_size.
metalsmith_traits: the default for traits.
metalsmith_user_name: the default for user_name, the default value is metalsmith.

Instance¶

Each instances has the following attributes:

candidates (defaults to metalsmith_candidates)

list of nodes (UUIDs or names) to be considered for deployment.

capabilities (defaults to metalsmith_capabilities)

node capabilities to request when scheduling.

conductor_group (defaults to metalsmith_conductor_group)

conductor group to pick nodes from.

Note

Currently it’s not possible to specify the default group.

extra_args (defaults to metalsmith_extra_args)

additional arguments to pass to the metalsmith CLI on all calls.

image (defaults to metalsmith_image)

UUID, name or HTTP(s) URL of the image to use for deployment. Mandatory.

image_checksum (defaults to metalsmith_image_checksum)

MD5 checksum or checksum file URL for an HTTP(s) image.

image_kernel (defaults to metalsmith_image_kernel)

URL of the kernel image if and only if the image is a URL of a partition image.

image_ramdisk (defaults to metalsmith_image_ramdisk)

URL of the ramdisk image if and only if the image is a URL of a partition image.

netboot

whether to boot the deployed instance from network (PXE, iPXE, etc). The default is to use local boot (requires a bootloader on the image).

nics (defaults to metalsmith_nics)

list of virtual NICs to attach to node’s physical NICs. Each is an object with exactly one attribute:

network

creates a port on the given network, for example:

nics:
  - network: private
  - network: ctlplane

can optionally take a fixed IP to assign:

nics:
  - network: private
    fixed_ip: 10.0.0.2
  - network: ctlplane
    fixed_ip: 192.168.42.30

port

uses the provided pre-created port:

nics:
  - port: b2254316-7867-4615-9fb7-911b3f38ca2a

subnet

creates a port on the given subnet, for example:

nics:
  - subnet: private-subnet1

resource_class (defaults to metalsmith_resource_class)

requested node’s resource class. Mandatory.

root_size (defaults to metalsmith_root_size)

size of the root partition (in GiB), if partition images are used.

Note

Also required for whole-disk images due to how the Bare Metal service currently works.

ssh_public_keys (defaults to metalsmith_ssh_public_keys)

list of file names with SSH public keys to put to the node.

swap_size (defaults to metalsmith_swap_size)

size of the swap partition (in MiB), if partition images are used (it’s an error to set it for a whole disk image).

traits

list of traits the node should have.

user_name (defaults to metalsmith_user_name)

name of the user to create on the instance via configdrive. Requires cloud-init on the image.

Module - metalsmith_instances¶

Module Documentation¶

Provision and unprovision ironic baremetal instances using metalsmith, which is a a simple tool to provision bare metal machines using OpenStack Bare Metal Service (ironic) and, optionally, OpenStack Image Service (glance) and OpenStack Networking Service (neutron).

Options¶

instances: List of node description dicts to perform operations on
clean_up: Clean up resources on failure
state: Desired provision state, "present" to provision, "absent" to unprovision, "reserved" to create an allocation record without changing the node state
wait: A boolean value instructing the module to wait for node provision to complete before returning. A 'yes' is implied if the number of instances is more than the concurrency.
timeout: An integer value representing the number of seconds to wait for the node provision to complete.
concurrency: Maximum number of instances to provision at once. Set to 0 to have no concurrency limit
log_level: Set the logging level for the log which is available in the returned 'logging' result.
