Optional configuration to support use of additional sources such as:

.

- ppa:myteam/ppa
|

- cloud:bionic-ussuri
|
||
- cloud:xenial-proposed/queens

.
|

The last option should be used in conjunction with the key configuration
|

option.
|

key:
|
||
type: string
|
||
default:
|
||
description: |
|
||
Key ID to import to the apt keyring to support use with arbitary source
|
||
configuration from outside of Launchpad archives or PPA's.
|

use-syslog:
|
||
type: boolean
|
||
default: False
|
||
description: |
|

If set to True, supporting services will log to syslog.
|
||
ceph-public-network:
|
||
type: string
|
||
default:
|
||
description: |
|
||
The IP address and netmask of the public (front-side) network (e.g.,
|
||
192.168.0.0/24).
|
||
If multiple networks are to be used, a space-delimited list of a.b.c.d/x
|
||
can be provided.
|
||
prefer-ipv6:
|
||
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.
|
||
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.
|
||

|
||
default:
|
||
type: string
|
||
description: |
|

|
||
default: replicated
|

|
||
and ‘erasure-coded’.
|
||
ec-profile-name:
|
||
type: string
|
||
default:
|
||
description: |
|
||
Name for the EC profile to be created for the EC pools. If not defined
|
||
a profile name will be generated based on the name of the pool used by
|
||
the application.
|
||
ec-rbd-metadata-pool:
|
||
type: string
|
||
default:
|
||
description: |
|
||
Name of the metadata pool to be created (for RBD use-cases). If not
|
||
defined a metadata pool name will be generated based on the name of
|
||
the data pool used by the application. The metadata pool is always
|
||
replicated, not erasure coded.
|
||
ec-profile-k:
|
||
type: int
|
||
default: 1
|
||
description: |
|
||
Number of data chunks that will be used for EC data pool. K+M factors
|
||
should never be greater than the number of available zones (or hosts)
|
||
for balancing.
|
||
ec-profile-m:
|
||
type: int
|
||
default: 2
|
||
description: |

ec-profile-locality:
|
||
type: int

default:
|
||
description: |
|
||
(lrc plugin - l) Group the coding and data chunks into sets of size l.
|
||
For instance, for k=4 and m=2, when l=3 two groups of three are created.
|
||
Each set can be recovered without reading chunks from another set. Note
|
||
that using the lrc plugin does incur more raw storage usage than isa or
|
||
jerasure in order to reduce the cost of recovery operations.
|
||
ec-profile-crush-locality:
|
||
type: string
|
||
default:
|
||
description: |
|
||
(lrc plugin) The type of the crush bucket in which each set of chunks
|
||
defined by l will be stored. For instance, if it is set to rack, each
|
||
group of l chunks will be placed in a different rack. It is used to
|
||
create a CRUSH rule step such as step choose rack. If it is not set,
|
||
no such grouping is done.

||
ec-profile-durability-estimator:
|
||
type: int
|
||
default:
|
||
description: |
|
||
(shec plugin - c) The number of parity chunks each of which includes
|
||
each data chunk in its calculation range. The number is used as a
|
||

||

|
||
recovery of a single chunk. d needs to be chosen such that
|
||
k+1 <= d <= k+m-1. Larger the d, the better the savings.
|
||
ec-profile-scalar-mds:
|
||

|
||
default:
|
||
