Exponent to determine number of hash partitions to use when distributing load across conductors. Larger values will result in more even distribution of load and less load when rebalancing the ring, but more memory usage. Number of partitions per conductor is (2^hash_partition_exponent). This determines the granularity of rebalancing: given 10 hosts, and an exponent of the 2, there are 40 partitions in the ring.A few thousand partitions should make rebalancing smooth in most cases. The default is suitable for up to a few hundred conductors. Configuring for too many partitions has a negative impact on CPU usage.

This option is only used when neither ESP nor ISO deploy image is configured to the node being deployed in which case ironic will attempt to fetch ESP image from the configured location or extract ESP image from UEFI-bootable deploy ISO image.

parallel_image_downloads¶

Type: boolean
Default: True
Mutable: This option can be changed without restarting.

IPv4 address of this host. If unset, will determine the IP programmatically. If unable to do so, will use “127.0.0.1”. NOTE: This field does accept an IPv6 address as an override for templates and URLs, however it is recommended that [DEFAULT]my_ipv6 is used along with DNS names for service URLs for dual-stack environments.

my_ipv6¶

Type: string
Default: 2001:db8::1

This option has a sample default set, which means that its actual default value may vary from the one documented above.

IP address of this host using IPv6. This value must be supplied via the configuration and cannot be adequately programmatically determined like the [DEFAULT]my_ip parameter for IPv4.

notification_level¶

Type: string

critical: “critical” level

versioned_notifications_topics¶

Type: list
Default: ['ironic_versioned_notifications']

Specifies the topics for the versioned notifications issued by Ironic.

The default value is fine for most deployments and rarely needs to be changed. However, if you have a third-party service that consumes versioned notifications, it might be worth getting a topic for that service. Ironic will send a message containing a versioned notification payload to each topic queue in this list.

The list of versioned notifications is visible in https://docs.openstack.org/ironic/latest/admin/notifications.html

Mutable: This option can be changed without restarting.

Used for rolling upgrades. Setting this option downgrades (or pins) the Bare Metal API, the internal ironic RPC communication, and the database objects to their respective versions, so they are compatible with older services.

rbac_service_project_name¶

Type: string
Default: service

The project name utilized for Role Based Access Control checks for the reserved service project. This project is utilized for services to have accounts for cross-service communication. Often these accounts require higher levels of access, and effectively this permits accounts from the service to not be restricted to project scoping of responses. i.e. The service project user with a service role will be able to see nodes across all projects, similar to System scoped access. If not set to a value, and all service role access will be filtered matching an owner or lessee, if applicable. If an operator wishes to make behavior visible for all service role users across all projects, then a custom policy must be used to override the default “service_role” rule. It should be noted that the value of “service” is a default convention for OpenStack deployments, but the requsite access and details around end configuration are largely up to an operator if they are doing an OpenStack deployment manually.

node_history_minimum_days¶

Type: integer
Default: 0
Minimum Value: 0
Mutable: This option can be changed without restarting.

The minimum number of days to explicitly keep on hand in the database history entries for nodes. This is exclusive from the [conductor]node_history_max_entries setting as users of this setting are anticipated to need to retain history by policy.

The concurrent deployment limit cannot be disabled.

max_concurrent_clean¶

Type: integer
Default: 50
Minimum Value: 1
Mutable: This option can be changed without restarting.

The maximum number of concurrent nodes in cleaning which are permitted in this Ironic system. If this limit is reached, new requests will be rejected until the number of nodes in cleaning is lower than this maximum. As this is a security mechanism requests are not queued, and this setting is a global setting applying to all requests this conductor receives, regardless of access rights. The concurrent clean limit cannot be disabled.

disable_deep_image_inspection¶

Type: boolean
Default: False

Security Option to permit an operator to disable file content inspections. Under normal conditions, the conductor will inspect requested image contents which are transferred through the conductor. Disabling this option is not advisable and opens the risk of unsafe images being processed which may allow an attacker to leverage unsafe features in various disk image formats to perform a variety of unsafe and potentially compromising actions. This option is not mutable, and requires a service restart to change.

conductor_always_validates_images¶

Type: boolean
Default: False

Security Option to enable the conductor to always inspect the image content of any requested deploy, even if the deployment would have normally bypassed the conductor’s cache. When this is set to False, the Ironic-Python-Agent is responsible for any necessary image checks. Setting this to True will result in a higher utilization of resources (disk space, network traffic) as the conductor will evaluate all images. This option is not mutable, and requires a service restart to change. This option requires [conductor]disable_deep_image_inspection to be set to False.

permitted_image_formats¶

Type: list
Default: ['raw', 'qcow2', 'iso']
Mutable: This option can be changed without restarting.

The supported list of image formats which are permitted for deployment with Ironic. If an image format outside of this list is detected, the image validation logic will fail the deployment process.

disable_file_checksum¶

Type: boolean
Default: False

Deprecated Security option: In the default case, image files have their checksums verified before undergoing additional conductor side actions such as image conversion. Enabling this option opens the risk of files being replaced at the source without the user’s knowledge.

Warning

This option is deprecated for removal. Its value may be silently ignored in the future.

disable_support_for_checksum_files¶

Type: boolean
Default: False

Security option: By default Ironic will attempt to retrieve a remote checksum file via HTTP(S) URL in order to validate an image download. This is functionality aligning with ironic-python-agent support for standalone users. Disabling this functionality by setting this option to True will create a more secure environment, however it may break users in an unexpected fashion.

Default: permissive

Used to control the use and type of token binding. Can be set to: “disabled” to not check token binding. “permissive” (default) to validate binding information if the bind type is of a form known to the server and ignore it if not. “strict” like “permissive” but if the bind type is unknown the token will be rejected. “required” any form of token binding is needed to be allowed. Finally the name of a binding method that must be present in tokens.

service_token_roles¶

Type: list
Default: ['service']

A choice of roles that must be present in a service token. Service tokens are allowed to request that an expired token can be used and so this check should tightly control that only actual services should be sending this token.

enforce_new_defaults¶

Type: boolean
Default: False

This option controls whether or not to use old deprecated defaults when evaluating policies. If True, the old deprecated defaults are not going to be evaluated. This means if any existing token is allowed for old defaults but is disallowed for new defaults, it will be disallowed. It is encouraged to enable this flag along with the enforce_scope flag so that you can get the benefits of new defaults and scope_type together. If False, the deprecated policy check string is logically OR’d with the new policy check string, allowing for a graceful upgrade experience between releases with new policies, which is the default behavior.
