This file is recommended for creating UEFI bootable ISO images efficiently. ESP image should contain a FAT12/16/32-formatted file system holding EFI boot loaders (e.g. GRUB2) for each hardware architecture ironic needs to boot. 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. executor_thread_pool_size = 64 integer value Size of executor thread pool when executor is threading or eventlet. fatal_deprecations = False boolean value Enables or disables fatal status of deprecations. force_raw_images = True boolean value If True, convert backing images to "raw" disk image format. graceful_shutdown_timeout = 60 integer value Specify a timeout after which a gracefully shutdown server will exit.

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. hash_ring_algorithm = md5 string value Hash function to use when building the hash ring. If running on a FIPS system, do not use md5. WARNING: all ironic services in a cluster MUST use the same algorithm at all times. Changing the algorithm requires an offline update. hash_ring_reset_interval = 15 integer value Time (in seconds) after which the hash ring is considered outdated and is refreshed on the access. host = <based on operating system> string value Name of this node. This can be an opaque identifier. It is not necessarily a hostname, FQDN, or IP address.

The default is for this option to be unset. parallel_image_downloads = False boolean value Run image downloads and raw format conversions in parallel. pecan_debug = False boolean value Enable pecan debug mode. WARNING: this is insecure and should not be used in a production environment. pin_release_version = None string value 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. When doing a rolling upgrade from version N to version N+1, set (to pin) this to N. To unpin (default), leave it unset and the latest versions will be used. publish_errors = False boolean value Enables or disables publication of error events. pybasedir = /usr/lib/python3.9/site-packages/ironic string value Directory where the ironic python module is installed. rate_limit_burst = 0 integer value Maximum number of logged messages per rate_limit_interval. rate_limit_except_level = CRITICAL string value Log level name used by rate limiting: CRITICAL, ERROR, INFO, WARNING, DEBUG or empty string.

This option is ignored if log_config_append is set. versioned_notifications_topics = ['ironic_versioned_notifications'] list value 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 watch-log-file = False boolean value Uses logging handler designed to watch file system. When log file is moved or removed this handler will open a new log file with specified path instantaneously. It makes sense only if log_file option is specified and Linux platform is used. This option is ignored if log_config_append is set. webserver_connection_timeout = 60 integer value Connection timeout when accessing remote web servers with images. webserver_verify_ca = True string value CA certificates to be used for certificate verification. This can be either a Boolean value or a path to a CA_BUNDLE file.If set to True, the certificates present in the standard path are used to verify the host certificates.If set to False, the conductor will ignore verifying the SSL certificate presented by the host.If it"s a path, conductor uses the specified certificate for SSL verification. If the path does not exist, the behavior is same as when this value is set to True i.e the certificates present in the standard path are used for SSL verification.Defaults to True. 5.1.2. agent The following table outlines the options available under the [agent] group in the /etc/ironic/ironic.conf file. Table 5.1. agent Configuration option = Default value Type Description agent_api_version = v1 string value API version to use for communicating with the ramdisk agent. api_ca_file = None string value Path to the TLS CA that is used to start the bare metal API.

By streaming raw images directly onto the disk the agent ramdisk will not spend time copying the image to a tmpfs partition (therefore consuming less memory) prior to writing it to the disk. Unless the disk where the image will be copied to is really slow, this option should be set to True. Defaults to True. verify_ca = True string value Path to the TLS CA to validate connection to the ramdisk. Set to True to use the system default CA storage. Set to False to disable validation.

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. Roles here are applied as an ANY check so any role in this list must be present. For backwards compatibility reasons this currently only affects the allow_expired check. service_token_roles_required = False boolean value For backwards compatibility reasons we must let valid service tokens pass that don't pass the service_token_roles check as valid.
