Upstream filters apply to the connections to the upstream cluster hosts.

{
  "name": ...,
  "typed_config": {...},
  "config_discovery": {...}
}

name

(string, REQUIRED) The name of the filter configuration.

typed_config

(Any) Filter specific configuration which depends on the filter being instantiated. See the supported filters for further documentation. Note that Envoy’s downstream network filters are not valid upstream filters. Only one of typed_config or config_discovery can be used.

config_discovery

(config.core.v3.ExtensionConfigSource) Configuration source specifier for an extension configuration discovery service. In case of a failure and without the default configuration, the listener closes the connections. Only one of typed_config or config_discovery can be used.
