instance the hostname would be something like:

use-internal-endpoints:
|
|
default: False
|
|
type: boolean
|
|
description: |
|

Openstack mostly defaults to using public endpoints for

type: boolean
|
|
default: False
|
|
description: |

If True enables IPv6 support. The charm will expect network interfaces
|
|
to be configured with an IPv6 address. If set to False (default) IPv4
|
|
is expected.
|
|
|
|
NOTE: these charms do not currently support IPv6 privacy extension. In
|
|
order for this charm to function correctly, the privacy extension must be
|
|
disabled and a non-temporary address must be configured/available on
|
|
your network interface.
|
|
cpu-mode:
|
|
type: string
|
|
default:
|
|
description: |
|

Set to 'host-model' to clone the host CPU feature flags; to
|
|
'host-passthrough' to use the host CPU model exactly; to 'custom' to
|
|
use a named CPU model; to 'none' to not set any CPU model. If
|
|
virt_type='kvm|qemu', it will default to 'host-model', otherwise it will
|
|
default to 'none'. Defaults to 'host-passthrough' for ppc64el, ppc64le

if no value is set.
|
|
cpu-model:
|
|
type: string
|
|
default:

# Storage configuration options
|
|
libvirt-image-backend:
|
|
type: string
|
|
default:
|
|
description: |
|
|
Tell Nova which libvirt image backend to use. Supported backends are rbd,
|
|
lvm and qcow2. If no backend is specified, the Nova default (qcow2) is
|
|
used. Note that rbd imagebackend is only supported with >= Juno.
|
|
rbd-pool:
|
|
type: string
|
|
default: 'nova'
|
|
description: |
|
|
RBD pool to use with Nova libvirt RBDImageBackend. Only required when you
|
|
have libvirt-image-backend set to 'rbd'.
|
|
rbd-client-cache:
|
|
type: string
|
|
default:
|
|
description: |
|
|
Enable/disable rbd client cache. Leaving this value unset will result in
|
|
default Ceph rbd client settings being used (rbd cache is enabled by
|
|
default for Ceph >= Giant). Supported values here are "enabled" or
|
|
"disabled".
|
|
ceph-osd-replication-count:
|
|
type: int
|
|
default: 3
|
|
description: |
|
|
This value dictates the number of replicas ceph must make of any
|
|
object it stores withing the nova rbd pool. Of course, this only
|
|
applies if using Ceph as a backend store. Note that once the nova
|
|
rbd pool has been created, changing this value will not have any
|
|
effect (although it can be changed in ceph by manually configuring
|
|
your ceph cluster).
|
|
ceph-pool-weight:
|
|
type: int
|
|
default: 30
|
|
description: |
|
|
Defines a relative weighting of the pool as a percentage of the total
|
|
amount of data in the Ceph cluster. This effectively weights the number
|
|
of placement groups for the pool created to be appropriately portioned
|
|
to the amount of data expected. For example, if the ephemeral volumes
|
|
for the OpenStack compute instances are expected to take up 20% of the
|
|
overall configuration then this value would be specified as 20. Note -
|
|
it is important to choose an appropriate value for the pool weight as
|
|
this directly affects the number of placement groups which will be
|
|
created for the pool. The number of placement groups for a pool can
|
|
only be increased, never decreased - so it is important to identify the
|
|
percent of data that will likely reside in the pool.

# Other configuration options
|

sysctl:

|
hugepages:
|
|
type: string
|
|
default:
|
|
description: |
|
|
The pecentage of system memory to use for hugepages eg '10%' or the total
|
|
number of 2M hugepages - eg "1024".
|
|
For a systemd system (wily and later) the prefered approach is to enable
|
|
hugepages via kernel parameters set in MAAS and systemd will mount them
|
|
automatically.
|
|
action-managed-upgrade:
|
|
type: boolean
|
|
default: False
|
|
description: |
|
|
If True enables openstack upgrades for this charm via juju actions.
|
|
You will still need to set openstack-origin to the new repository but
|
|
instead of an upgrade running automatically across all units, it will
|
|
wait for you to execute the openstack-upgrade action for this charm on
|
|
each unit. If False it will revert to existing behavior of upgrading
|
|
all units on config change.
|
|
os-internal-network:
|
|
type: string
|
|
default:
|
|
description: |
|
