Command line arguments ΒΆ

The following command line arguments are accepted by the Ingress controller executable.

They are set in the container spec of the ingress-nginx-controller Deployment manifest

Argument Description
--annotations-prefix Prefix of the Ingress annotations specific to the NGINX controller. (default "nginx.ingress.kubernetes.io")
--apiserver-host Address of the Kubernetes API server. Takes the form "protocol://address:port". If not specified, it is assumed the program runs inside a Kubernetes cluster and local discovery is attempted.
--certificate-authority Path to a cert file for the certificate authority. This certificate is used only when the flag --apiserver-host is specified.
--configmap Name of the ConfigMap containing custom global configurations for the controller.
--controller-class Ingress Class Controller value this Ingress satisfies. The class of an Ingress object is set using the field IngressClassName in Kubernetes clusters version v1.19.0 or higher. The .spec.controller value of the IngressClass referenced in an Ingress Object should be the same value specified here to make this object be watched.
--deep-inspect Enables ingress object security deep inspector. (default true)
--default-backend-service Service used to serve HTTP requests not matching any known server name (catch-all). Takes the form "namespace/name". The controller configures NGINX to forward requests to the first port of this Service.
--default-server-port Port to use for exposing the default server (catch-all). (default 8181)
--default-ssl-certificate Secret containing a SSL certificate to be used by the default HTTPS server (catch-all). Takes the form "namespace/name".
--enable-annotation-validation If true, will enable the annotation validation feature. This value will be defaulted to true on a future release.
--disable-catch-all Disable support for catch-all Ingresses. (default false)
--disable-full-test Disable full test of all merged ingresses at the admission stage and tests the template of the ingress being created or updated (full test of all ingresses is enabled by default).
--disable-svc-external-name Disable support for Services of type ExternalName. (default false)

--dynamic-configuration-retries Number of times to retry failed dynamic configuration before failing to sync an ingress. (default 15)
--election-id Election id to use for Ingress status updates. (default "ingress-controller-leader")
--enable-metrics Enables the collection of NGINX metrics. (default true)
--enable-ssl-chain-completion Autocomplete SSL certificate chains with missing intermediate CA certificates. Certificates uploaded to Kubernetes must have the "Authority Information Access" X.509 v3 extension for this to succeed. (default false)
--enable-ssl-passthrough Enable SSL Passthrough. (default false)
--disable-leader-election Disable Leader Election on Nginx Controller. (default false)
--enable-topology-aware-routing Enable topology aware routing feature, needs service object annotation service.kubernetes.io/topology-mode sets to auto. (default false)
--exclude-socket-metrics Set of socket request metrics to exclude which won't be exported nor being calculated. The possible socket request metrics to exclude are documented in the monitoring guide e.g. 'nginx_ingress_controller_request_duration_seconds,nginx_ingress_controller_response_size'

--ingress-class Name of the ingress class this controller satisfies. The class of an Ingress object is set using the field IngressClassName in Kubernetes clusters version v1.18.0 or higher or the annotation "kubernetes.io/ingress.class" (deprecated). If this parameter is not set, or set to the default value of "nginx", it will handle ingresses with either an empty or "nginx" class name.

--length-buckets Set of buckets which will be used for prometheus histogram metrics such as RequestLength, ResponseLength. (default [10, 20, 30, 40, 50, 60, 70, 80, 90, 100])
--maxmind-edition-ids Maxmind edition ids to download GeoLite2 Databases. (default "GeoLite2-City,GeoLite2-ASN")

--profiling Enable profiling via web interface host:port/debug/pprof/ . (default true)
--publish-service Service fronting the Ingress controller. Takes the form "namespace/name". When used together with update-status, the controller mirrors the address of this service's endpoints to the load-balancer status of all Ingress objects it satisfies.
--publish-status-address Customized address (or addresses, separated by comma) to set as the load-balancer status of Ingress objects this controller satisfies. Requires the update-status parameter.
--report-node-internal-ip-address Set the load-balancer status of Ingress objects to internal Node addresses instead of external. Requires the update-status parameter. (default false)

--update-status Update the load-balancer status of Ingress objects this controller satisfies. Requires setting the publish-service parameter to a valid Service reference. (default true)
--update-status-on-shutdown Update the load-balancer status of Ingress objects when the controller shuts down. Requires the update-status parameter. (default true)
--shutdown-grace-period Seconds to wait after receiving the shutdown signal, before stopping the nginx process. (default 0)
