getNodeContextParamsList

public com.google.protobuf.ProtocolStringList getNodeContextParamsList()

 A list of :ref:`Node <envoy_v3_api_msg_config.core.v3.Node>` field names
 that will be included in the context parameters of the effective
 xdstp:// URL that is sent in a discovery request when resource
 locators are used for LDS/CDS. Any non-string field will have its JSON
 encoding set as the context parameter value, with the exception of
 metadata, which will be flattened (see example below). The supported field
 names are:
 - "cluster"
 - "id"
 - "locality.region"
 - "locality.sub_zone"
 - "locality.zone"
 - "metadata"
 - "user_agent_build_version.metadata"
 - "user_agent_build_version.version"

 - "user_agent_version"
 The node context parameters act as a base layer dictionary for the context
 parameters (i.e. more specific resource specific context parameters will
 override). Field names will be prefixed with “udpa.node.” when included in
 context parameters.
 For example, if node_context_params is ``["user_agent_name", "metadata"]``,
 the implied context parameters might be::
   node.user_agent_name: "envoy"
   node.metadata.foo: "{\"bar\": \"baz\"}"
