Description |
clientTLS
|
object
|
clientTLS specifies settings for requesting and verifying client certificates, which can be used to enable mutual TLS for edge-terminated and reencrypt routes. |
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. |
httpEmptyRequestsPolicy
|
string
|
httpEmptyRequestsPolicy describes how HTTP connections should be handled if the connection times out before a request is received. Allowed values for this field are "Respond" and "Ignore". If the field is set to "Respond", the ingress controller sends an HTTP 400 or 408 response, logs the connection (if access logging is enabled), and counts the connection in the appropriate metrics. If the field is set to "Ignore", the ingress controller closes the connection without sending a response, logging the connection, or incrementing metrics. The default value is "Respond".
Typically, these connections come from load balancers' health probes or Web browsers' speculative connections ("preconnect") and can be safely ignored. However, these requests may also be caused by network errors, and so setting this field to "Ignore" may impede detection and diagnosis of problems. In addition, these requests may be caused by port scans, in which case logging empty requests may aid in detecting intrusion attempts. |
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. |
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

private
|
object
|

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. |

* "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". |
headerNameCaseAdjustments
|
`` |
headerNameCaseAdjustments specifies case adjustments that can be applied to HTTP header names. Each adjustment is specified as an HTTP header name with the desired capitalization. For example, specifying "X-Forwarded-For" indicates that the "x-forwarded-for" HTTP header should be adjusted to have the specified capitalization.
These adjustments are only applied to cleartext, edge-terminated, and re-encrypt routes, and only when using HTTP/1.
For request headers, these adjustments are applied only for routes that have the haproxy.router.openshift.io/h1-adjust-case=true annotation. For response headers, these adjustments are applied to all HTTP responses.
If this field is empty, no request headers are adjusted. |
uniqueId

object
Property |
Type |
Description |
effect
|
string
|
Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute. |
key
|
string
|
Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys. |
operator
|
string
|
Operator represents a key’s relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category. |
tolerationSeconds
|
integer
|
TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system. |
value
|
string
|
Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string. |
.spec.routeAdmission

namespaceOwnership describes how host name claims across namespaces should be handled.
Value must be one of:
- Strict: Do not allow routes in different namespaces to claim the same host.
- InterNamespaceAllowed: Allow routes to claim different paths of the same host name across namespaces.
If empty, the default is Strict. |
wildcardPolicy
|
string
|
wildcardPolicy describes how routes with wildcard policies should be handled for the ingress controller. WildcardPolicy controls use of routes [1] exposed by the ingress controller based on the route’s wildcard policy.
[1] https://github.com/openshift/api/blob/master/route/v1/types.go
Note: Updating WildcardPolicy from WildcardsAllowed to WildcardsDisallowed will cause admitted routes with a wildcard policy of Subdomain to stop working. These routes must be updated to a wildcard policy of None to be readmitted by the ingress controller.
WildcardPolicy supports WildcardsAllowed and WildcardsDisallowed values.
If empty, defaults to "WildcardsDisallowed". |
.spec.routeSelector

.spec.tlsSecurityProfile
- Description
-
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.

string
|
type is one of Old, Intermediate, Modern or Custom. Custom provides the ability to specify individual TLS security profile parameters. Old, Intermediate and Modern are TLS security profiles based on:
https://wiki.mozilla.org/Security/Server_Side_TLS#Recommended_configurations
The profiles are intent based, so they may change over time as new ciphers are developed and existing ciphers are found to be insecure. Depending on precisely which ciphers are available to a process, the list may be reduced.
Note that the Modern profile is currently not supported because it is not yet well adopted by common software libraries. |
.spec.tuningOptions
- Description
-
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.
- Type

object
Property |
Type |
Description |
clientFinTimeout
|
string
|
clientFinTimeout defines how long a connection will be held open while waiting for the client response to the server/backend closing the connection.
If unset, the default timeout is 1s |
clientTimeout
|
string
|
clientTimeout defines how long a connection will be held open while waiting for a client response.
If unset, the default timeout is 30s |
headerBufferBytes
|
integer
|
headerBufferBytes describes how much memory should be reserved (in bytes) for IngressController connection sessions. Note that this value must be at least 16384 if HTTP/2 is enabled for the IngressController (https://tools.ietf.org/html/rfc7540). If this field is empty, the IngressController will use a default value of 32768 bytes.
Setting this field is generally not recommended as headerBufferBytes values that are too small may break the IngressController and headerBufferBytes values that are too large could cause the IngressController to use significantly more memory than necessary. |
headerBufferMaxRewriteBytes
|
integer
|
headerBufferMaxRewriteBytes describes how much memory should be reserved (in bytes) from headerBufferBytes for HTTP header rewriting and appending for IngressController connection sessions. Note that incoming HTTP requests will be limited to (headerBufferBytes - headerBufferMaxRewriteBytes) bytes, meaning headerBufferBytes must be greater than headerBufferMaxRewriteBytes. If this field is empty, the IngressController will use a default value of 8192 bytes.
Setting this field is generally not recommended as headerBufferMaxRewriteBytes values that are too small may break the IngressController and headerBufferMaxRewriteBytes values that are too large could cause the IngressController to use significantly more memory than necessary. |
serverFinTimeout
|
string
|
serverFinTimeout defines how long a connection will be held open while waiting for the server/backend response to the client closing the connection.
If unset, the default timeout is 1s |
serverTimeout
|
string
|
serverTimeout defines how long a connection will be held open while waiting for a server/backend response.
If unset, the default timeout is 30s |
threadCount
|
integer
|
threadCount defines the number of threads created per HAProxy process. Creating more threads allows each ingress controller pod to handle more connections, at the cost of more system resources being used. HAProxy currently supports up to 64 threads. If this field is empty, the IngressController will use the default value. The current default is 4 threads, but this may change in future releases.
Setting this field is generally not recommended. Increasing the number of HAProxy threads allows ingress controller pods to utilize more CPU time under load, potentially starving other pods if set too high. Reducing the number of threads may cause the ingress controller to perform poorly. |
tlsInspectDelay
|
string
|
tlsInspectDelay defines how long the router can hold data to find a matching route.
Setting this too short can cause the router to fall back to the default certificate for edge-terminated or reencrypt routes even when a better matching certificate could be used.
If unset, the default inspect delay is 5s |
tunnelTimeout
|
string
|
tunnelTimeout defines how long a tunnel connection (including websockets) will be held open while the tunnel is idle.
If unset, the default timeout is 1h |

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.
