Scheduler Filters

The following extra specs are specific to various in-tree scheduler filters.

aggregate_instance_extra_specs

The following extra specs are used to specify metadata that must be present on the aggregate of a host. If this metadata is not present or does not match the expected value, the aggregate and all hosts within in will be rejected.

Requires the AggregateInstanceExtraSpecsFilter scheduler filter.

aggregate_instance_extra_specs:{key}
Type:

str

Specify metadata that must be present on the aggregate of a host. If this metadata is not present, the host will be rejected. Requires the AggregateInstanceExtraSpecsFilter scheduler filter.

The value can be one of the following:

  • = (equal to or greater than as a number; same as vcpus case)

  • == (equal to as a number)

  • != (not equal to as a number)

  • >= (greater than or equal to as a number)

  • <= (less than or equal to as a number)

  • s== (equal to as a string)

  • s!= (not equal to as a string)

  • s>= (greater than or equal to as a string)

  • s> (greater than as a string)

  • s<= (less than or equal to as a string)

  • s< (less than as a string)

  • <in> (substring)

  • <all-in> (all elements contained in collection)

  • <or> (find one of these)

  • A specific value, e.g. true, 123, testing

capabilities

The following extra specs are used to specify a host capability that must be provided by the host compute service. If this capability is not present or does not match the expected value, the host will be rejected.

Requires the ComputeCapabilitiesFilter scheduler filter.

All extra specs expect similar types of values:

  • = (equal to or greater than as a number; same as vcpus case)

  • == (equal to as a number)

  • != (not equal to as a number)

  • >= (greater than or equal to as a number)

  • <= (less than or equal to as a number)

  • s== (equal to as a string)

  • s!= (not equal to as a string)

  • s>= (greater than or equal to as a string)

  • s> (greater than as a string)

  • s<= (less than or equal to as a string)

  • s< (less than as a string)

  • <in> (substring)

  • <all-in> (all elements contained in collection)

  • <or> (find one of these)

  • A specific value, e.g. true, 123, testing

Examples are: >= 5, s== 2.1.0, <in> gcc, <all-in> aes mmx, and <or> fpu <or> gpu

Note

Not all operators will apply to all types of values. For example, the == operator should not be used for a string value - use s== instead.
