IngressController [operator.openshift.io/v1]

apiVersion

string

APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

kind

string

Kind is a string value representing the ReST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

metadata

ObjectMeta_v2 meta/v1

Standard object’s metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

spec

object

spec is the specification of the desired behavior of the IngressController.

status

object

status is the most recently observed status of the IngressController.

defaultCertificate

object

defaultCertificate is a reference to a secret containing the default certificate served by the ingress controller. When Routes don’t specify their own certificate, defaultCertificate is used. The secret must contain the following keys and data: tls.crt: certificate file contents tls.key: key file contents If unset, a wildcard certificate is automatically generated and used. The certificate is valid for the ingress controller domain (and subdomains) and the generated certificate’s CA will be automatically integrated with the cluster’s trust store. If a wildcard certificate is used and shared by multiple HTTP/2 enabled routes (which implies ALPN) then clients (i.e., notably browsers) are at liberty to reuse open connections. This means a client can reuse a connection to another route and that is likely to fail. This behaviour is generally known as connection coalescing. The in-use certificate (whether generated or user-specified) will be automatically integrated with OpenShift’s built-in OAuth server.

domain

string

domain is a DNS name serviced by the ingress controller and is used to configure multiple features: * For the LoadBalancerService endpoint publishing strategy, domain is used to configure DNS records. See endpointPublishingStrategy. * When using a generated default certificate, the certificate will be valid for domain and its subdomains. See defaultCertificate. * The value is published to individual Route statuses so that end-users know where to target external DNS records. domain must be unique among all IngressControllers, and cannot be updated. If empty, defaults to ingress.config.openshift.io/cluster .spec.domain.

endpointPublishingStrategy

object

endpointPublishingStrategy is used to publish the ingress controller endpoints to other networks, enable load balancer integrations, etc. If unset, the default is based on infrastructure.config.openshift.io/cluster .status.platform: AWS: LoadBalancerService (with external scope) Azure: LoadBalancerService (with external scope) GCP: LoadBalancerService (with external scope) IBMCloud: LoadBalancerService (with external scope) Libvirt: HostNetwork Any other platform types (including None) default to HostNetwork. endpointPublishingStrategy cannot be updated.

httperrorCodePages

object

httperrorCodePages specifies a configmap with custom error pages. The administrator must create this configmap in the openshift-config namespace. This configmap should have keys in the format "error-page-<error code>.http", where <error code> is an HTTP error code. For example, "error-page-503.http" defines an error page for HTTP 503 responses. Currently only error pages for 503 and 404 responses can be customized. each value in the configmap should be the full response, including HTTP headers. eg- https://raw.githubusercontent.com/openshift/router/fadab45747a9b30cc3f0a4b41ad2871f95827a93/images/router/haproxy/conf/error-page-503.http If this field is empty, the ingress controller uses the default error pages.

httpHeaders

object

httpHeaders defines policy for HTTP headers. If this field is empty, the default values are used.

logging

object

logging defines parameters for what should be logged where. If this field is empty, operational logs are enabled but access logs are disabled.

namespaceSelector

object

namespaceSelector is used to filter the set of namespaces serviced by the ingress controller. This is useful for implementing shards. If unset, the default is no filtering.

nodePlacement

object

nodePlacement enables explicit control over the scheduling of the ingress controller. If unset, defaults are used. See NodePlacement for more details.

replicas

integer

replicas is the desired number of ingress controller replicas. If unset, defaults to 2.

routeAdmission

object

routeAdmission defines a policy for handling new route claims (for example, to allow or deny claims across namespaces). If empty, defaults will be applied. See specific routeAdmission fields for details about their defaults.

routeSelector

object

routeSelector is used to filter the set of Routes serviced by the ingress controller. This is useful for implementing shards. If unset, the default is no filtering.

tlsSecurityProfile

object

tlsSecurityProfile specifies settings for TLS connections for ingresscontrollers. If unset, the default is based on the apiservers.config.openshift.io/cluster resource. Note that when using the Old, Intermediate, and Modern profile types, the effective profile configuration is subject to change between releases. For example, given a specification to use the Intermediate profile deployed on release X.Y.Z, an upgrade to release X.Y.Z+1 may cause a new profile configuration to be applied to the ingress controller, resulting in a rollout. Note that the minimum TLS version for ingress controllers is 1.1, and the maximum TLS version is 1.2. An implication of this restriction is that the Modern TLS profile type cannot be used because it requires TLS 1.3.

tuningOptions

object

tuningOptions defines parameters for adjusting the performance of ingress controller pods. All fields are optional and will use their respective defaults if not set. See specific tuningOptions fields for more details. Setting fields within tuningOptions is generally not recommended. The default values are suitable for most configurations.

unsupportedConfigOverrides

``

unsupportedConfigOverrides allows specifying unsupported configuration options. Its use is unsupported.

name

string

Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names TODO: Add other useful fields. apiVersion, kind, uid?

hostNetwork

object

hostNetwork holds parameters for the HostNetwork endpoint publishing strategy. Present only if type is HostNetwork.

loadBalancer

object

loadBalancer holds parameters for the load balancer. Present only if type is LoadBalancerService.

nodePort

object

nodePort holds parameters for the NodePortService endpoint publishing strategy. Present only if type is NodePortService.

private

object

private holds parameters for the Private endpoint publishing strategy. Present only if type is Private.

type

string

type is the publishing strategy to use. Valid values are: * LoadBalancerService Publishes the ingress controller using a Kubernetes LoadBalancer Service. In this configuration, the ingress controller deployment uses container networking. A LoadBalancer Service is created to publish the deployment. See: https://kubernetes.io/docs/concepts/services-networking/service/#loadbalancer If domain is set, a wildcard DNS record will be managed to point at the LoadBalancer Service’s external name. DNS records are managed only in DNS zones defined by dns.config.openshift.io/cluster .spec.publicZone and .spec.privateZone. Wildcard DNS management is currently supported only on the AWS, Azure, and GCP platforms. * HostNetwork Publishes the ingress controller on node ports where the ingress controller is deployed. In this configuration, the ingress controller deployment uses host networking, bound to node ports 80 and 443. The user is responsible for configuring an external load balancer to publish the ingress controller via the node ports. * Private Does not publish the ingress controller. In this configuration, the ingress controller deployment uses container networking, and is not explicitly published. The user must manually publish the ingress controller. * NodePortService Publishes the ingress controller using a Kubernetes NodePort Service. In this configuration, the ingress controller deployment uses container networking. A NodePort Service is created to publish the deployment. The specific node ports are dynamically allocated by OpenShift; however, to support static port allocations, user changes to the node port field of the managed NodePort Service will preserved.

protocol

string

protocol specifies whether the IngressController expects incoming connections to use plain TCP or whether the IngressController expects PROXY protocol. PROXY protocol can be used with load balancers that support it to communicate the source addresses of client connections when forwarding those connections to the IngressController. Using PROXY protocol enables the IngressController to report those source addresses instead of reporting the load balancer’s address in HTTP headers and logs. Note that enabling PROXY protocol on the IngressController will cause connections to fail if you are not using a load balancer that uses PROXY protocol to forward connections to the IngressController. See http://www.haproxy.org/download/2.2/doc/proxy-protocol.txt for information about PROXY protocol. The following values are valid for this field: * The empty string. * "TCP". * "PROXY". The empty string specifies the default, which is TCP without PROXY protocol. Note that the default is subject to change.

providerParameters

object

providerParameters holds desired load balancer information specific to the underlying infrastructure provider. If empty, defaults will be applied. See specific providerParameters fields for details about their defaults.

scope

string

scope indicates the scope at which the load balancer is exposed. Possible values are "external" and "Internal".

aws

object

aws provides configuration settings that are specific to AWS load balancers. If empty, defaults will be applied. See specific aws fields for details about their defaults.

gcp

object

gcp provides configuration settings that are specific to GCP load balancers. If empty, defaults will be applied. See specific gcp fields for details about their defaults.

type

string

type is the underlying infrastructure provider for the load balancer. Allowed values are "AWS", "Azure", "BareMetal", "GCP", "OpenStack", and "VSphere".

classicLoadBalancer

object

classicLoadBalancerParameters holds configuration parameters for an AWS classic load balancer. Present only if type is Classic.

networkLoadBalancer

object

networkLoadBalancerParameters holds configuration parameters for an AWS network load balancer. Present only if type is NLB.

type

string

type is the type of AWS load balancer to instantiate for an ingresscontroller. Valid values are: * "Classic": A Classic Load Balancer that makes routing decisions at either the transport layer (TCP/SSL) or the application layer (HTTP/HTTPS). See the following for additional details: https://docs.aws.amazon.com/AmazoneCS/latest/developerguide/load-balancer-types.html#clb * "NLB": A Network Load Balancer that makes routing decisions at the transport layer (TCP/SSL). See the following for additional details: https://docs.aws.amazon.com/AmazoneCS/latest/developerguide/load-balancer-types.html#nlb

clientAccess

string

clientAccess describes how client access is restricted for internal load balancers. Valid values are: * "Global": Specifying an internal load balancer with Global client access allows clients from any region within the VPC to communicate with the load balancer. https://cloud.google.com/kubernetes-engine/docs/how-to/internal-load-balancing#global_access * "Local": Specifying an internal load balancer with Local client access means only clients within the same region (and VPC) as the GCP load balancer can communicate with the load balancer. Note that this is the default behavior. https://cloud.google.com/load-balancing/docs/internal#client_access

protocol

string

protocol specifies whether the IngressController expects incoming connections to use plain TCP or whether the IngressController expects PROXY protocol. PROXY protocol can be used with load balancers that support it to communicate the source addresses of client connections when forwarding those connections to the IngressController. Using PROXY protocol enables the IngressController to report those source addresses instead of reporting the load balancer’s address in HTTP headers and logs. Note that enabling PROXY protocol on the IngressController will cause connections to fail if you are not using a load balancer that uses PROXY protocol to forward connections to the IngressController. See http://www.haproxy.org/download/2.2/doc/proxy-protocol.txt for information about PROXY protocol. The following values are valid for this field: * The empty string. * "TCP". * "PROXY". The empty string specifies the default, which is TCP without PROXY protocol. Note that the default is subject to change.

name

string

name is the metadata.name of the referenced config map

forwardedHeaderPolicy

string

forwardedHeaderPolicy specifies when and how the IngressController sets the Forwarded, X-Forwarded-For, X-Forwarded-Host, X-Forwarded-Port, X-Forwarded-Proto, and X-Forwarded-Proto-Version HTTP headers. The value may be one of the following: * "Append", which specifies that the IngressController appends the headers, preserving existing headers. * "Replace", which specifies that the IngressController sets the headers, replacing any existing Forwarded or X-Forwarded-* headers. * "IfNone", which specifies that the IngressController sets the headers if they are not already set. * "Never", which specifies that the IngressController never sets the headers, preserving any existing headers. By default, the policy is "Append".
