options:
debug:
type: boolean
default: False
description: Enable debug logging.
verbose:
type: boolean
default: False
description: Enable verbose logging.
use-syslog:
type: boolean
default: False
description: |
Setting this to True will allow supporting services to log to syslog.
openstack-origin:
type: string
default: distro
description: |
Repository from which to install. May be one of the following:
distro (default), ppa:somecustom/ppa, a deb url sources entry,
or a supported Ubuntu Cloud Archive e.g.
.
cloud:<series>-<openstack-release>
cloud:<series>-<openstack-release>/updates
cloud:<series>-<openstack-release>/staging
cloud:<series>-<openstack-release>/proposed
.
See https://wiki.ubuntu.com/OpenStack/CloudArchive for info on which
cloud archives are available and supported.
.
NOTE: updating this setting to a source that is known to provide
a later version of OpenStack will trigger a software upgrade unless
action-managed-upgrade is set to True.
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.
harden:
type: string
default:
description: |
Apply system hardening. Supports a space-delimited list of modules
to run. Supported modules currently include os, ssh, apache and mysql.
database-user:
type: string
default: glance
description: Database username
database:
type: string
default: glance
description: Glance database name.
api-config-flags:
type: string
default:
description: |
Comma-separated list of key=value pairs to be added to glance-api.conf
where 'value' may itself be a comma-separated list of values to be
assigned to the 'key'.
registry-config-flags:
type: string
default:
description: |
Comma-separated list of key=value pairs to be added to
glance-registry.conf where 'value' may itself be a comma-separated list
of values to be assigned to the 'key'.
region:
type: string
default: RegionOne
description: OpenStack Region
use-internal-endpoints:
type: boolean
default: False
description: |
Openstack mostly defaults to using public endpoints for
internal communication between services. If set to True this option will
configure services to use internal endpoints where possible.
ceph-osd-replication-count:
type: int
default: 3
description: |
This value dictates the number of replicas ceph must make of any
object it stores within the images rbd pool. Of course, this only
applies if using Ceph as a backend store. Note that once the images
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: 5
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 compute images
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.
restrict-ceph-pools:
type: boolean
default: False
description: |
Optionally restrict Ceph key permissions to access pools as required.
worker-multiplier:
type: float
default:
description: |
The CPU core multiplier to use when configuring worker processes for
Glance. By default, the number of workers for each daemon is set to
twice the number of CPU cores a service unit has. When deployed in
a LXD container, this default value will be capped to 4 workers
unless this configuration option is set.
expose-image-locations:
type: boolean
default: True
description: |
Expose underlying image locations via the API when using Ceph for image
storage. Only disable this option if you do not wish to use
copy-on-write clones of RAW format images with Ceph in Cinder and Nova.
restrict-image-location-operations:
type: boolean
default: False
description: |
If this is set to True, all *_image_location operations in the Glance api
will be restricted to role:admin which will result in non-admin users no
longer being able to view the "locations" information for an image.
This only affects environments that have expose-image-locations set to
True.
WARNING: enabling this restriction will cause Nova to no longer be able
to create COW clones or snapshots for non-admin users when using the
RBDImageBackend in the nova-compute charm.
rabbit-user:
type: string
default: glance
description: Username to request access on rabbitmq-server.
rabbit-vhost:
type: string
default: openstack
description: RabbitMQ virtual host to request access on rabbitmq-server.

type: string
default:
description: |

disk-formats:
type: string
default: ami,ari,aki,vhd,vmdk,raw,qcow2,vdi,iso,root-tar
description: |
Comma separated list of disk formats that Glance will support.
image-size-cap:
type: string
default: 1TB
description: |
Maximum size of image a user can upload. Defaults to 1TB
(1099511627776 bytes). Example values: 500M, 500MB, 5G, 5TB.
Valid units: K, KB, M, MB, G, GB, T, TB, P, PB. If no units provided,
bytes are assumed.
.
WARNING: this value should only be increased after careful consideration
and must be set to a value under 8EB (9223372036854775808 bytes).

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

your network interface.
# Monitoring config
nagios_context:
type: string
default: "juju"
description: |
Used by the nrpe-external-master subordinate charm. A string that will
be prepended to instance name to set the host name in nagios. So for
instance the hostname would be something like 'juju-myservice-0'. If
you are running multiple environments with the same services in them
this allows you to differentiate between them.
nagios_servicegroups:
type: string
default: ""
description: |

If left empty, the nagios_context will be used as the servicegroup
filesystem-store-datadir:
type: string

Directory to which the filesystem backend store writes images.
Upon start up, Glance creates the directory if it doesn’t already exist
and verifies write access to the user under which glance-api runs. If
the write access isn’t available, a BadStoreConfiguration exception is
raised and the filesystem store may not be available for adding new
images. NOTE: This directory is used only when filesystem store is used
as a storage backend.
