This page lists the capabilities of the GatewayClass resources available on Google Kubernetes Engine (GKE) and their supported specifications.
Table legend
For the various tables in this document, the legend for the tables is as follows:
- indicates that the field is supported.
-indicates that the field is not supported.- If GKE supports some values in the field, the table describes what values are supported.
