Expression
Expression is a CEL expression which evaluates a single device. It must evaluate
to true when the device under consideration satisfies the desired criteria, and
false when it does not. Any other result is an error and causes allocation of
devices to abort.
The expression's input is an object named "device", which carries the following
properties:
- driver (string): the name of the driver which defines this device.
- attributes (map[string]object): the device's attributes, grouped by prefix
(e.g. device.attributes["dra.example.com"] evaluates to an object with all
of the attributes which were prefixed by "dra.example.com".
- capacity (map[string]object): the device's capacities, grouped by prefix.
Example: Consider a device with driver="dra.example.com", which exposes two
attributes named "model" and "ext.example.com/family" and which exposes one
capacity named "modules". This input to this expression would have the following
fields:
device.driver
device.attributes["dra.example.com"].model
device.attributes["ext.example.com"].family
device.capacity["dra.example.com"].modules
The device.driver field can be used to check for a specific driver, either as a
high-level precondition (i.e. you only want to consider devices from this
driver) or as part of a multi-clause expression that is meant to consider
devices from different drivers.
The value type of each attribute is defined by the device definition, and users
who write these expressions must consult the documentation for their specific
drivers. The value type of each capacity is Quantity.
If an unknown prefix is used as a lookup in either device.attributes or
device.capacity, an empty map will be returned. Any reference to an unknown
field will cause an evaluation error and allocation to abort.
A robust expression should check for the existence of attributes before
referencing them.
For ease of use, the cel.bind() function is enabled, and can be used to simplify
expressions that access multiple attributes with the same domain. For example:
cel.bind(dra, device.attributes["dra.example.com"], dra.someBool & &
dra.anotherBool)
The length of the expression must be smaller or equal to 10 Ki. The cost of
evaluating it is also limited based on the estimated number of logical steps.
