Overview

Opaque filter criteria used by load balancers to restrict routing configuration to a limited set of load balancing proxies. Proxies and sidecars involved in load balancing would typically present metadata to the load balancers that need to match criteria specified here. If a match takes place, the relevant configuration is made available to those proxies. For each metadataFilter in this list, if itsfilterMatchCriteria is set to MATCH_ANY, at least one of thefilterLabels must match the corresponding label provided in the metadata. If its filterMatchCriteria is set to MATCH_ALL, then all of its filterLabels must match with corresponding labels provided in the metadata. An example for using metadataFilters would be: if load balancing involves Envoys, they receive routing configuration when values inmetadataFilters match values supplied in of their XDS requests to loadbalancers.

Instance Attribute Summary

• #filter_labels ⇒ Array<Google::Apis::ComputeAlpha::MetadataFilterLabelMatch>

#filter_match_criteria ⇒ String

Specifies how individual filter label matches within the list of filterLabels and contributes toward the overall metadataFilter match. Supported values are:

• MATCH_ANY: at least one of the filterLabels must have a matching label in the provided metadata.
• MATCH_ALL: all filterLabels must have matching labels in the provided metadata. Corresponds to the JSON property filterMatchCriteria

Returns:

• (String)
