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".

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

uniqueId describes configuration for a custom HTTP header that the ingress controller should inject into incoming HTTP requests. Typically, this header is configured to have a value that is unique to the HTTP request. The header can be used by applications or included in access logs to facilitate tracing individual HTTP requests. If this field is empty, no such header is injected into requests.

format

string

format specifies the format for the injected HTTP header’s value. This field has no effect unless name is specified. For the HAProxy-based ingress controller implementation, this format uses the same syntax as the HTTP log format. If the field is empty, the default value is "%{+X}o\\ %ci:%cp_%fi:%fp_%Ts_%rt:%pid"; see the corresponding HAProxy documentation: http://cbonte.github.io/haproxy-dconv/2.0/configuration.html#8.2.3

name

string

name specifies the name of the HTTP header (for example, "unique-id") that the ingress controller should inject into HTTP requests. The field’s value must be a valid HTTP header name as defined in RFC 2616 section 4.2. If the field is empty, no header is injected.

access

object

access describes how the client requests should be logged. If this field is empty, access logging is disabled.

destination

object

httpCaptureCookies

``

httpCaptureCookies specifies HTTP cookies that should be captured in access logs. If this field is empty, no cookies are captured.

httpCaptureHeaders

object

httpCaptureHeaders defines HTTP headers that should be captured in access logs. If this field is empty, no headers are captured. Note that this option only applies to cleartext HTTP connections and to secure HTTP connections for which the ingress controller terminates encryption (that is, edge-terminated or reencrypt connections). Headers cannot be captured for TLS passthrough connections.

httpLogFormat

string

httpLogFormat specifies the format of the log message for an HTTP request. If this field is empty, log messages use the implementation’s default HTTP log format. For HAProxy’s default HTTP log format, see the HAProxy documentation: http://cbonte.github.io/haproxy-dconv/2.0/configuration.html#8.2.3 Note that this format only applies to cleartext HTTP connections and to secure HTTP connections for which the ingress controller terminates encryption (that is, edge-terminated or reencrypt connections). It does not affect the log format for TLS passthrough connections.

container

object

container holds parameters for the Container logging destination. Present only if type is Container.

syslog

object

syslog holds parameters for a syslog endpoint. Present only if type is Syslog.

type

string

type is the type of destination for logs. It must be one of the following: * Container The ingress operator configures the sidecar container named "logs" on the ingress controller pod and configures the ingress controller to write logs to the sidecar. The logs are then available as container logs. The expectation is that the administrator configures a custom logging solution that reads logs from this sidecar. Note that using container logs means that logs may be dropped if the rate of logs exceeds the container runtime’s or the custom logging solution’s capacity. * Syslog Logs are sent to a syslog endpoint. The administrator must specify an endpoint that can receive syslog messages. The expectation is that the administrator has configured a custom syslog instance.

address

string

address is the IP address of the syslog endpoint that receives log messages.

facility

string

facility specifies the syslog facility of log messages. If this field is empty, the facility is "local1".

port

integer

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.

custom

``

custom is a user-defined TLS security profile. Be extremely careful using a custom profile as invalid configurations can be catastrophic. An example custom profile looks like this: ciphers: - ECDHE-ECDSA-CHACHA20-POLY1305 - ECDHE-RSA-CHACHA20-POLY1305 - ECDHE-RSA-AES128-GCM-SHA256 - ECDHE-ECDSA-AES128-GCM-SHA256 minTLSVersion: TLSv1.1

intermediate

``

intermediate is a TLS security profile based on: https://wiki.mozilla.org/Security/Server_Side_TLS#Intermediate_compatibility_.28recommended.29 and looks like this (yaml): ciphers: - TLS_AES_128_GCM_SHA256 - TLS_AES_256_GCM_SHA384 - TLS_CHACHA20_POLY1305_SHA256 - ECDHE-ECDSA-AES128-GCM-SHA256 - ECDHE-RSA-AES128-GCM-SHA256 - ECDHE-ECDSA-AES256-GCM-SHA384 - ECDHE-RSA-AES256-GCM-SHA384 - ECDHE-ECDSA-CHACHA20-POLY1305 - ECDHE-RSA-CHACHA20-POLY1305 - DHE-RSA-AES128-GCM-SHA256 - DHE-RSA-AES256-GCM-SHA384 minTLSVersion: TLSv1.2

old

``

old is a TLS security profile based on: https://wiki.mozilla.org/Security/Server_Side_TLS#Old_backward_compatibility and looks like this (yaml): ciphers: - TLS_AES_128_GCM_SHA256 - TLS_AES_256_GCM_SHA384 - TLS_CHACHA20_POLY1305_SHA256 - ECDHE-ECDSA-AES128-GCM-SHA256 - ECDHE-RSA-AES128-GCM-SHA256 - ECDHE-ECDSA-AES256-GCM-SHA384 - ECDHE-RSA-AES256-GCM-SHA384 - ECDHE-ECDSA-CHACHA20-POLY1305 - ECDHE-RSA-CHACHA20-POLY1305 - DHE-RSA-AES128-GCM-SHA256 - DHE-RSA-AES256-GCM-SHA384 - DHE-RSA-CHACHA20-POLY1305 - ECDHE-ECDSA-AES128-SHA256 - ECDHE-RSA-AES128-SHA256 - ECDHE-ECDSA-AES128-SHA - ECDHE-RSA-AES128-SHA - ECDHE-ECDSA-AES256-SHA384 - ECDHE-RSA-AES256-SHA384 - ECDHE-ECDSA-AES256-SHA - ECDHE-RSA-AES256-SHA - DHE-RSA-AES128-SHA256 - DHE-RSA-AES256-SHA256 - AES128-GCM-SHA256 - AES256-GCM-SHA384 - AES128-SHA256 - AES256-SHA256 - AES128-SHA - AES256-SHA - DES-CBC3-SHA minTLSVersion: TLSv1.0

type

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.

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.

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. 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.

availableReplicas

integer

availableReplicas is number of observed available replicas according to the ingress controller deployment.

conditions

array

conditions is a list of conditions and their status. Available means the ingress controller deployment is available and servicing route and ingress resources (i.e, .status.availableReplicas equals .spec.replicas) There are additional conditions which indicate the status of other ingress controller features and capabilities. * LoadBalancerManaged - True if the following conditions are met: * The endpoint publishing strategy requires a service load balancer. - False if any of those conditions are unsatisfied. * LoadBalancerReady - True if the following conditions are met: * A load balancer is managed. * The load balancer is ready. - False if any of those conditions are unsatisfied. * DNSManaged - True if the following conditions are met: * The endpoint publishing strategy and platform support DNS. * The ingress controller domain is set. * dns.config.openshift.io/cluster configures DNS zones. - False if any of those conditions are unsatisfied. * DNSReady - True if the following conditions are met: * DNS is managed. * DNS records have been successfully created. - False if any of those conditions are unsatisfied.

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.

ciphers

array (string)

ciphers is used to specify the cipher algorithms that are negotiated during the TLS handshake. Operators may remove entries their operands do not support. For example, to use DES-CBC3-SHA (yaml): ciphers: - DES-CBC3-SHA

minTLSVersion

string

minTLSVersion is used to specify the minimal version of the TLS protocol that is negotiated during the TLS handshake. For example, to use TLS versions 1.1, 1.2 and 1.3 (yaml): minTLSVersion: TLSv1.1 NOTE: currently the highest minTLSVersion allowed is VersionTLS12
