Add support for max request header size #5368
Description
Description:
I've been trying different things to allow requests with a particularly large Authorization header to be accepted. This is how I configured EnvoyProxy with a JSONPatch on the bootstrap configuration.
apiVersion: gateway.envoyproxy.io/v1alpha1
kind: EnvoyProxy
metadata:
name: custom-proxy-config
namespace: envoy
spec:
mergeGateways: true
bootstrap:
type: JSONPatch
jsonPatches:
- op: "add"
jsonPath: "static_resources.listeners[0].filter_chains[0].filters[0].typed_config"
path: "max_request_headers_kb"
value: 96I can see it reflecting on my pods:
listeners:
- address:
socketAddress:
address: 0.0.0.0
portValue: 19001
filterChains:
- filters:
- name: envoy.filters.network.http_connection_manager
typedConfig:
'@type': type.googleapis.com/envoy.extensions.filters.network.http_connection_manager.v3.HttpConnectionManager
httpFilters:
- name: envoy.filters.http.health_check
typedConfig:
'@type': type.googleapis.com/envoy.extensions.filters.http.health_check.v3.HealthCheck
headers:
- name: :path
stringMatch:
exact: /ready
passThroughMode: false
- name: envoy.filters.http.router
typedConfig:
'@type': type.googleapis.com/envoy.extensions.filters.http.router.v3.Router
maxRequestHeadersKb: 96
routeConfig:
name: local_route
virtualHosts:
- domains:
- '*'
name: prometheus_stats
routes:
- match:
prefix: /stats/prometheus
route:
cluster: prometheus_stats
statPrefix: eg-ready-http
name: envoy-gateway-proxy-ready-0.0.0.0-19001But I still get status 431 Request Header Fields Too Large. Any help appreciated.
