filter
|
A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160 . These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either For example, if you are filtering Compute Engine instances, you can exclude instances named The
You can also filter nested fields. For example, you could specify To filter on multiple expressions, provide each separate expression within parentheses. For example:
By default, each expression is an
If you want to use a regular expression, use the The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use You cannot combine constraints on multiple fields using regular expressions. |
orderBy
|
Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using Currently, only sorting by |
returnPartialSuccess
|
Opt-in for partial success behavior which provides partial results in case of failure. The default value is false. For example, when partial success behavior is enabled, aggregatedList for a single zone scope either returns all resources in the zone or no resources, with an error code. |
