Grpc Credentials File Based Metadata¶

This documentation is for the Envoy v3 API.

As of Envoy v1.18 the v2 API has been removed and is no longer supported.

If you are upgrading from v2 API config you may wish to view the v2 API documentation:

config/grpc_credential/v2alpha/file_based_metadata.proto

This extension may be referenced by the qualified name envoy.grpc_credentials.file_based_metadata

Note

This extension does not operate on the data plane and hence is intended to be robust against untrusted traffic.

Tip

This extension extends and can be used with the following extension category:
