Upstream filters

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:

api/v2/cluster/filter.proto

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

config.cluster.v3.Filter

[config.cluster.v3.Filter proto]

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

name

(string, REQUIRED) The name of the filter to instantiate. The name must match a supported upstream filter. Note that Envoy’s downstream network filters are not valid upstream filters.

typed_config

(Any) Filter specific configuration which depends on the filter being instantiated. See the supported filters for further documentation.
