Method Detail

getName

String getName()

 The unique name by which this listener is known. If no name is provided,
 Envoy will allocate an internal UUID for the listener. If the listener is to be dynamically
 updated or removed via :ref:`LDS <config_listeners_lds>` a unique name must be provided.
 By default, the maximum length of a listener's name is limited to 60 characters. This limit can
 be increased by setting the :option:`--max-obj-name-len` command line argument to the desired
 value.
 

string name = 1;

getNameBytes

com.google.protobuf.ByteString getNameBytes()

 The unique name by which this listener is known. If no name is provided,
 Envoy will allocate an internal UUID for the listener. If the listener is to be dynamically
 updated or removed via :ref:`LDS <config_listeners_lds>` a unique name must be provided.

hasAddress

boolean hasAddress()

 The address that the listener should listen on. In general, the address must be unique, though
 that is governed by the bind rules of the OS. E.g., multiple listeners can listen on port 0 on
 Linux as the actual port will be allocated by the OS.
 

.envoy.api.v2.core.Address address = 2 [(.gogoproto.nullable) = false, (.validate.rules) = { ... }

getAddress

AddressOuterClass.Address getAddress()

 The address that the listener should listen on. In general, the address must be unique, though
 that is governed by the bind rules of the OS. E.g., multiple listeners can listen on port 0 on
 Linux as the actual port will be allocated by the OS.

 A list of filter chains to consider for this listener. The

   In the current version, multiple filter chains are supported **only** so that SNI can be

   **identical** set of :ref:`filters <envoy_api_field_listener.FilterChain.filters>`. If the

hasUseOriginalDst

@Deprecated
boolean hasUseOriginalDst()

Deprecated.

 If a connection is redirected using *iptables*, the port on which the proxy
 receives it might be different from the original destination address. When this flag is set to
 true, the listener hands off redirected connections to the listener associated with the
 original destination address. If there is no listener associated with the original destination
 address, the connection is handled by the listener that receives it. Defaults to false.
 .. attention::
   This field is deprecated. Use :ref:`an original_dst <config_listener_filters_original_dst>`
   :ref:`listener filter <envoy_api_field_Listener.listener_filters>` instead.
   Note that hand off to another listener is *NOT* performed without this flag. Once
   :ref:`FilterChainMatch <envoy_api_msg_listener.FilterChainMatch>` is implemented this flag
   will be removed, as filter chain matching can be used to select a filter chain based on the
   restored destination address.

hasTransparent

boolean hasTransparent()

 Whether the listener should be set as a transparent socket.
 When this flag is set to true, connections can be redirected to the listener using an
 *iptables* *TPROXY* target, in which case the original source and destination addresses and
 ports are preserved on accepted connections. This flag should be used in combination with
 :ref:`an original_dst <config_listener_filters_original_dst>` :ref:`listener filter
 <envoy_api_field_Listener.listener_filters>` to mark the connections' local addresses as
 "restored." This can be used to hand off each redirected connection to another listener
 associated with the connection's destination address. Direct connections to the socket without
 using *TPROXY* cannot be distinguished from connections redirected using *TPROXY* and are
 therefore treated as if they were redirected.
 When this flag is set to false, the listener's socket is explicitly reset as non-transparent.
 Setting this flag requires Envoy to run with the *CAP_NET_ADMIN* capability.
 When this flag is not set (default), the socket is not modified, i.e. the transparent option
 is neither set nor reset.

 the socket, with a queue length of the specified size
 (see `details in RFC7413 <https://tools.ietf.org/html/rfc7413#section-5.1>`_).

 When this flag is not set (default), the socket is not modified,

 TCP_FASTOPEN.
