getTransportSocketMatchesList

public List<Cluster.TransportSocketMatch> getTransportSocketMatchesList()

Configuration to use different transport sockets for different endpoints.
The entry of *envoy.transport_socket_match* in the
:ref:`LbEndpoint.Metadata <envoy_api_field_config.endpoint.v3.LbEndpoint.metadata>`
is used to match against the transport sockets as they appear in the list. The first
:ref:`match <envoy_api_msg_config.cluster.v4alpha.Cluster.TransportSocketMatch>` is used.
For example, with the following match
.. code-block:: yaml
transport_socket_matches:
- name: "enableMTLS"
match:
acceptMTLS: true
transport_socket:
name: envoy.transport_sockets.tls
config: { ... } # tls socket configuration
- name: "defaultToPlaintext"
match: {}
transport_socket:
name: envoy.transport_sockets.raw_buffer
Connections to the endpoints whose metadata value under *envoy.transport_socket_match*
having "acceptMTLS"/"true" key/value pair use the "enableMTLS" socket configuration.
If a :ref:`socket match <envoy_api_msg_config.cluster.v4alpha.Cluster.TransportSocketMatch>` with empty match
criteria is provided, that always match any endpoint. For example, the "defaultToPlaintext"
socket match in case above.
If an endpoint metadata's value under *envoy.transport_socket_match* does not match any
*TransportSocketMatch*, socket configuration fallbacks to use the *tls_context* or
*transport_socket* specified in this cluster.
This field allows gradual and flexible transport socket configuration changes.
The metadata of endpoints in EDS can indicate transport socket capabilities. For example,
an endpoint's metadata can have two key value pairs as "acceptMTLS": "true",
"acceptPlaintext": "true". While some other endpoints, only accepting plaintext traffic
has "acceptPlaintext": "true" metadata information.
Then the xDS server can configure the CDS to a client, Envoy A, to send mutual TLS
traffic for endpoints with "acceptMTLS": "true", by adding a corresponding
*TransportSocketMatch* in this field. Other client Envoys receive CDS without
*transport_socket_match* set, and still send plain text traffic to the same cluster.
This field can be used to specify custom transport socket configurations for health
checks by adding matching key/value pairs in a health check's
:ref:`transport socket match criteria <envoy_api_field_config.core.v4alpha.HealthCheck.transport_socket_match_criteria>` field.
