Command Line Reference¶

allocation candidate list¶

List allocation candidates.

Returns a representation of a collection of allocation requests and resource provider summaries. Each allocation request has information to issue an “openstack resource provider allocation set” request to claim resources against a related set of resource providers.

As several allocation requests are available its necessary to select one. To make a decision, resource provider summaries are provided with the inventory/capacity information.

For example:

$ export OS_PLACEMENT_API_VERSION=1.10
$ openstack allocation candidate list --resource VCPU=1
+---+------------+-------------------------+-------------------------+
| # | allocation | resource provider       | inventory used/capacity |
+---+------------+-------------------------+-------------------------+
| 1 | VCPU=1     | 66bcaca9-9263-45b1-a569 | VCPU=0/128              |
|   |            | -ea708ff7a968           |                         |
+---+------------+-------------------------+-------------------------+

In this case, the user is looking for resource providers that can have capacity to allocate 1 VCPU resource class. There is one resource provider that can serve that allocation request and that resource providers current VCPU inventory used is 0 and available capacity is 128.

This command requires at least --os-placement-api-version 1.10.

--resource <resource_class>=<value>¶: String indicating an amount of resource of a specified class that providers in each allocation request must collectively have the capacity and availability to serve. Can be specified multiple times per resource class. For example: --resource VCP=4 --resource DISK_GB=64 --resource MEMORY_MB=2048

name¶: Name of the resource class

This command is provided by the osc-placement plugin.

uuid¶: UUID of the consumer

This command is provided by the osc-placement plugin.

resource provider allocation set¶

Replaces the set of resource allocation(s) for a given consumer.

Note that this is a full replacement of the existing allocations. If you want to retain the existing allocations and add a new resource class allocation, you must specify all resource class allocations, old and new.

From --os-placement-api-version 1.8 it is required to specify --project-id and --user-id to set allocations. It is highly recommended to provide a --project-id and --user-id when setting allocations for accounting and data consistency reasons.

Starting with --os-placement-api-version 1.12 the API response contains the project_id and user_id of allocations which also appears in the CLI output.

Starting with --os-placement-api-version 1.28 a consumer generation is used which facilitates safe concurrent modification of an allocation.

openstack resource provider allocation set
    [--sort-column SORT_COLUMN]
    [--allocation <rp=resource-provider-id,resource-class-name=amount-of-resource-used>]
    [--project-id project_id]
    [--user-id user_id]
    <uuid>

--sort-column SORT_COLUMN¶: specify the column(s) to sort the data (columns specified first have a priority, non-existing columns are ignored), can be repeated

--project-id project_id¶: ID of the consuming project. This option is required starting from --os-placement-api-version 1.8.

--user-id user_id¶: ID of the consuming user. This option is required starting from --os-placement-api-version 1.8.

uuid¶: UUID of the consumer

This command is provided by the osc-placement plugin.

resource provider allocation show¶

Show resource allocations for a given consumer.

Starting with --os-placement-api-version 1.12 the API response contains the project_id and user_id of allocations which also appears in the CLI output.

openstack resource provider allocation show
    [--sort-column SORT_COLUMN]
    <uuid>

--sort-column SORT_COLUMN¶: specify the column(s) to sort the data (columns specified first have a priority, non-existing columns are ignored), can be repeated

uuid¶: UUID of the consumer

This command is provided by the osc-placement plugin.

resource provider allocation unset¶

Removes one or more sets of provider allocations for a consumer.

Note that omitting the --provider option is equivalent to removing all allocations for the given consumer.

openstack resource provider allocation unset
    [--sort-column SORT_COLUMN]
    [--provider provider_uuid]
    <consumer_uuid>

--sort-column SORT_COLUMN¶: specify the column(s) to sort the data (columns specified first have a priority, non-existing columns are ignored), can be repeated

--provider provider_uuid¶: UUID of a specific resource provider from which to remove allocations for the given consumer. This is useful when the consumer has allocations on more than one provider, for example after evacuating a server to another compute node and you want to cleanup allocations on the source compute node resource provider in order to delete it. It is strongly recommended to use --os-placement-api-version 1.28 or greater when using this option to ensure the other allocation information is retained. Specify multiple times to remove allocations against multiple resource providers. Omit this option to remove all allocations for the consumer.

consumer_uuid¶: UUID of the consumer

This command is provided by the osc-placement plugin.

resource provider create¶

Create a new resource provider

openstack resource provider create
    [--parent-provider <parent_provider>]

name¶: Name of the resource provider

This command is provided by the osc-placement plugin.

resource provider delete¶

Delete a resource provider

openstack resource provider delete <uuid>

--total <total>¶: The actual amount of the resource that the provider can accommodate.

uuid¶: UUID of the resource provider

If a specific inventory field is not specified for a given resource class, it is assumed to be the total, i.e. –resource VCPU=16 is equivalent to –resource VCPU:total=16.

Example: openstack resource provider inventory set <uuid> –resource VCPU=16 –resource MEMORY_MB=2048 –resource MEMORY_MB:step_size=128

openstack resource provider inventory set
    [--sort-column SORT_COLUMN]
    [--resource <resource_class>:<inventory_field>=<value>]
    [--aggregate]
    [--amend]
    [--dry-run]
    <uuid>

--sort-column SORT_COLUMN¶: specify the column(s) to sort the data (columns specified first have a priority, non-existing columns are ignored), can be repeated

--resource <resource_class>:<inventory_field>=<value>¶: String describing resource. <resource_class> is an entity that indicates standard or deployer-specific resources that can be provided by a resource provider. For example, VCPU, MEMORY_MB, DISK_GB. <inventory_field> (optional) can be: allocation_ratio - it is used in determining whether consumption of the resource of the provider can exceed physical constraints. for example, for a vcpu resource with: allocation_ratio = 16.0, total = 8. overall capacity is equal to 128 vcpus. min_unit - a minimum amount any single allocation against an inventory can have. max_unit - a maximum amount any single allocation against an inventory can have. reserved - the amount of the resource a provider has reserved for its own use. step_size - a representation of the divisible amount of the resource that may be requested. for example, step_size = 5 means that only values divisible by 5 (5, 10, 15, etc.) can be requested. total - the actual amount of the resource that the provider can accommodate.
