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.

listing the git repositories to install from.
.
The default Openstack release name may be one of the following, where
the corresponding OpenStack github branch will be used:
* liberty
* mitaka
* newton
* master
.
The YAML must minimally include requirements, neutron, and nova
repositories, and may also include repositories for other dependencies:
repositories:
- {name: requirements,
repository: 'git://github.com/openstack/requirements',
branch: master}
- {name: neutron,
repository: 'git://github.com/openstack/neutron',

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.
ssl_cert:
type: string
default:
description: |
SSL certificate to install and use for API ports. Setting this value
and ssl_key will enable reverse proxying, point Nova's entry in the
Keystone catalog to use https, and override any certificate and key
issued by Keystone (if it is configured to do so).

type: string
default:
description: SSL key to use with certificate specified as ssl_cert.
ssl_ca:
type: string
default:
description: |
SSL CA to use with the certificate and key provided - this is only
required if you are providing a privately signed ssl_cert and ssl_key.
service-guard:
type: boolean
default: false
description: |
Ensure required relations are made and complete before allowing services
to be started
.
By default, services may be up and accepting API request from install
onwards.
.
Enabling this flag ensures that services will not be started until the
minimum 'core relations' have been made between this charm and other
charms.
.
For this charm the following relations must be made:
.
* shared-db
* amqp
* identity-service
console-access-protocol:
type: string
default:
description: |
Protocol to use when accessing virtual machine console. Supported types
are None, spice, xvpvnc, novnc and vnc (for both xvpvnc and novnc).
console-proxy-ip:
type: string
default: local
description: |
If console-access-protocol != None then this is the ip published to
clients for access to console proxy. Set to local for the ip address of
the nova-cloud-controller serving the request to be used.
console-keymap:
type: string
default: 'en-us'
description: |
Console keymap.
console-ssl-cert:
type: string
default:
description: |
Used for encrypted console connections. This differs from the SSL
certificate used for API endpoints and is used for console sessions only.
Setting this value along with console-ssl-key will enable encrypted
console sessions. This has nothing to do with Nova API SSL and can be
used independently. This can be used in conjunction when
console-access-protocol is set to 'novnc' or 'spice'.
console-ssl-key:
type: string
default:
description: SSL key to use with certificate specified as console-ssl-cert.
enable-serial-console:
type: boolean
default: false
description: |
Enable serial console access to instances using websockets (insecure).
This is only supported on OpenStack Juno or later, and will disable the
normal console-log output for an instance.
worker-multiplier:
type: float
default:
description: |
The CPU core multiplier to use when configuring worker processes for
this service. 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.
cpu-allocation-ratio:
type: float
default: 16.0
description: |
The per physical core -> virtual core ratio to use in the Nova scheduler.
.
Increasing this value will increase instance density on compute nodes
at the expense of instance performance.
ram-allocation-ratio:
type: float
default: 1.5
description: |
The physical ram -> virtual ram ratio to use in the Nova scheduler.
.
Increasing this value will increase instance density on compute nodes
at the potential expense of instance performance.
disk-allocation-ratio:
type: float
default: 1.0
description: |
Increase the amount of disk space that nova can overcommit to guests.
.
Increasing this value will increase instance density on compute nodes
with an increased risk of hypervisor storage becoming full.
single-nova-consoleauth:
type: boolean
default: true
description: |
When this configuration is set to True, a single instance of
nova-consoleauth service will be running, this allows users to always
authenticate against the same instance and avoid authentications issues
when the token used was stored in a different instance.
.
If memcached is being used to store the tokens, then it's recommended to
change this configuration to False.
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.
scheduler-default-filters:
type: string
default: "RetryFilter,AvailabilityZoneFilter,CoreFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter"
description: |
List of filter class names to use for filtering hosts when not specified in
the request.
pci-alias:
type: string
default:
description: |
The pci-passthrough-whitelist option of nova-compute charm is used for
specifying which PCI devices are allowed passthrough. pci-alias is more
a convenience that can be used in conjunction with Nova flavor properties
to automatically assign required PCI devices to new instances. You could,
for example, have a GPU flavor or a SR-IOV flavor:
.
pci-alias='{"vendor_id":"8086","product_id":"10ca","name":"a1"}'
.
This configures a new PCI alias 'a1' which will request a PCI device with
a vendor id of 0x8086 and a product id of 10ca.
.
For more information about the syntax of pci_alias, refer to
https://docs.openstack.org/ocata/config-reference/compute/config-options.html

type: string
default:
description: |

file under the "filter:ratelimit" section as "limits".
.
The syntax for these rules is documented at:
http://docs.openstack.org/kilo/config-reference/content/configuring-compute-API.html
disable-aws-compat:
type: boolean
default: false
description: |
For OpenStack Icehouse, Juno and Kilo by default a compatibility layer
for EC2 and S3 is configured, setting this option to `true` the services
are stopped and disabled.

disabled and a non-temporary address must be configured/available on
your network interface.

If you're running multiple environments with the same services in them
this allows you to differentiate between them.
