--- title: "Envoy" description: "An integration guide for Authelia and the Envoy reverse proxy" lead: "A guide on integrating Authelia with the Envoy reverse proxy." date: 2022-06-15T17:51:47+10:00 draft: false images: [] menu: integration: parent: "proxies" weight: 330 toc: true aliases: - /i/envoy --- [Envoy] is supported by __Authelia__. *__Important:__ When using these guides it's important to recognize that we cannot provide a guide for every possible method of deploying a proxy. These guides show a suggested setup only and you need to understand the proxy configuration and customize it to your needs. To-that-end we include links to the official proxy documentation throughout this documentation and in the [See Also](#see-also) section.* ## Get Started It's __*strongly recommended*__ that users setting up *Authelia* for the first time take a look at our [Get Started](../prologue/get-started.md) guide. This takes you through various steps which are essential to bootstrapping *Authelia*. ## Trusted Proxies *__Important:__ You should read the [Forwarded Headers] section and this section as part of any proxy configuration. Especially if you have never read it before.* *__Important:__ The included example is __NOT__ meant for production use. It's used expressly as an example to showcase how you can configure multiple IP ranges. You should customize this example to fit your specific architecture and needs. You should only include the specific IP address ranges of the trusted proxies within your architecture and should not trust entire subnets unless that subnet only has trusted proxies and no other services.* ## Configuration Below you will find commented examples of the following configuration: * Authelia Portal * Protected Endpoint (Nextcloud) ### Example Support for [Envoy] is possible with Authelia v4.37.0 and higher via [Envoy]'s [external authorization](https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/filters/http/ext_authz/v3/ext_authz.proto.html#extensions-filters-http-ext-authz-v3-extauthz). {{< details "docker-compose.yaml" >}} ```yaml --- version: "3.8" networks: net: driver: bridge services: envoy: container_name: envoy image: envoyproxy/envoy:v1.23.0 restart: unless-stopped networks: net: {} ports: - '80:8080' - '443:8443' volumes: - ${PWD}/data/envoy/envoy.yaml:/etc/envoy/envoy.yaml:ro - ${PWD}/data/certificates:/certificates:ro authelia: container_name: authelia image: authelia/authelia restart: unless-stopped networks: net: {} expose: - 9091 volumes: - ${PWD}/data/authelia/config:/config environment: TZ: "Australia/Melbourne" nextcloud: container_name: nextcloud image: linuxserver/nextcloud restart: unless-stopped networks: net: {} expose: - 443 volumes: - ${PWD}/data/nextcloud/config:/config - ${PWD}/data/nextcloud/data:/data environment: PUID: "1000" PGID: "1000" TZ: "Australia/Melbourne" ``` {{< /details >}} {{< details "envoy.yaml" >}} ```yaml static_resources: listeners: - name: listener_http address: socket_address: address: 0.0.0.0 port_value: 8080 filter_chains: - filters: - name: envoy.filters.network.http_connection_manager typed_config: "@type": type.googleapis.com/envoy.extensions.filters.network.http_connection_manager.v3.HttpConnectionManager codec_type: auto stat_prefix: ingress_http route_config: name: local_route virtual_hosts: - name: backend domains: ["*"] routes: - match: prefix: "/" redirect: https_redirect: true http_filters: - name: envoy.filters.http.router typed_config: "@type": type.googleapis.com/envoy.extensions.filters.http.router.v3.Router - name: listener_https address: socket_address: address: 0.0.0.0 port_value: 8443 filter_chains: - filters: - name: envoy.filters.network.http_connection_manager typed_config: "@type": type.googleapis.com/envoy.extensions.filters.network.http_connection_manager.v3.HttpConnectionManager stat_prefix: ingress_http use_remote_address: true skip_xff_append: false route_config: name: local_route virtual_hosts: - name: whoami_service domains: ["nextcloud.example.com"] routes: - match: prefix: "/" route: cluster: nextcloud - name: authelia_service domains: ["auth.example.com"] typed_per_filter_config: envoy.filters.http.ext_authz: "@type": type.googleapis.com/envoy.extensions.filters.http.ext_authz.v3.ExtAuthzPerRoute disabled: true routes: - match: prefix: "/" route: cluster: authelia http_filters: - name: envoy.filters.http.ext_authz typed_config: "@type": type.googleapis.com/envoy.extensions.filters.http.ext_authz.v3.ExtAuthz http_service: path_prefix: '/api/verify/' server_uri: uri: authelia:9091 cluster: authelia timeout: 0.25s authorization_request: allowed_headers: patterns: - exact: accept - exact: cookie - exact: proxy-authorization headers_to_add: - key: X-Authelia-URL value: 'https://auth.example.com/' - key: X-Forwarded-Method value: '%REQ(:METHOD)%' - key: X-Forwarded-Proto value: '%REQ(:SCHEME)%' - key: X-Forwarded-Host value: '%REQ(:AUTHORITY)%' - key: X-Forwarded-Uri value: '%REQ(:PATH)%' - key: X-Forwarded-For value: '%DOWNSTREAM_REMOTE_ADDRESS_WITHOUT_PORT%' authorization_response: allowed_upstream_headers: patterns: - exact: authorization - exact: proxy-authorization - prefix: remote- - prefix: authelia- allowed_client_headers: patterns: - exact: set-cookie allowed_client_headers_on_success: patterns: - exact: set-cookie failure_mode_allow: false - name: envoy.filters.http.router typed_config: "@type": type.googleapis.com/envoy.extensions.filters.http.router.v3.Router clusters: - name: nextcloud connect_timeout: 0.25s type: LOGICAL_DNS dns_lookup_family: V4_ONLY lb_policy: ROUND_ROBIN load_assignment: cluster_name: nextcloud endpoints: - lb_endpoints: - endpoint: address: socket_address: address: nextcloud port_value: 80 - name: authelia connect_timeout: 0.25s type: LOGICAL_DNS dns_lookup_family: V4_ONLY lb_policy: ROUND_ROBIN load_assignment: cluster_name: authelia endpoints: - lb_endpoints: - endpoint: address: socket_address: address: authelia port_value: 9091 ``` {{< /details >}} ## See Also * [Envoy External Authorization Documentation](https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/filters/http/ext_authz/v3/ext_authz.proto.html#extensions-filters-http-ext-authz-v3-extauthz) * [Forwarded Headers] [Envoy]: https://www.envoyproxy.io/ [Forwarded Headers]: fowarded-headers
