Traefik & Kubernetes with Gateway API¶
The Kubernetes Gateway API, The Experimental Way.
Gateway API is the evolution of Kubernetes APIs that relate to Services, such as Ingress.
The Gateway API project is part of Kubernetes, working under SIG-NETWORK.
The Kubernetes Gateway provider is a Traefik implementation of the Gateway API specifications from the Kubernetes Special Interest Groups (SIGs).
This provider is proposed as an experimental feature and partially supports Gateway API v1.0.0 specification.
Enabling The Experimental Kubernetes Gateway Provider
Since this provider is still experimental, it needs to be activated in the experimental section of the static configuration.
experimental:
kubernetesGateway: true
providers:
kubernetesGateway: {}
#...[experimental]
kubernetesGateway = true
[providers.kubernetesGateway]
#...--experimental.kubernetesgateway=true --providers.kubernetesgateway=true #...Requirements¶
Traefik follows the Kubernetes support policy, and supports at least the latest three minor versions of Kubernetes. General functionality cannot be guaranteed for versions older than that.
All Steps for a Successful Deployment
- Add/update the Kubernetes Gateway API definitions.
- Add/update the RBAC for the Traefik custom resources.
- Add all needed Kubernetes Gateway API resources.

HTTPRoute, Port: 80, Protocol: HTTP 2. HTTPRoute, Port: 443, Protocol: HTTPS, TLS Mode: Terminate, TLS keypair provided \n TLS Profile \n 1. TLSRoute, Port: 443, Protocol: TLS, TLS Mode: Passthrough \n \"Distinct\" Listeners have the following property: \n The implementation can match inbound requests to a single distinct Listener. When multiple Listeners share values for fields (for example, two Listeners with the same Port value), the implementation can match requests to only one of the Listeners using other Listener fields. \n For example, the following Listener scenarios are distinct: \n 1. Multiple Listeners with the same Port that all use the \"HTTP\" Protocol that all have unique Hostname values. 2. Multiple Listeners with the same Port that use either the \"HTTPS\" or \"TLS\" Protocol that all have unique Hostname values. 3. A mixture of \"TCP\" and \"UDP\" Protocol Listeners, where no Listener with the same Protocol has the same Port value. \n Some fields in the Listener struct have possible values that affect whether the Listener is distinct. Hostname is particularly relevant for HTTP or HTTPS protocols. \n When using the Hostname value to select between same-Port, same-Protocol Listeners, the Hostname value must be different on each Listener for the Listener to be distinct. \n When the Listeners are distinct based on Hostname, inbound request hostnames MUST match from the most specific to least specific Hostname values to choose the correct Listener and its associated set of Routes. \n Exact matches must be processed before wildcard matches, and wildcard matches must be processed before fallback (empty Hostname value) matches. For example, `\"foo.example.com\"` takes precedence over `\"*.example.com\"`, and `\"*.example.com\"` takes precedence over `\"\"`. \n Additionally, if there are multiple wildcard entries, more specific wildcard entries must be processed before less specific wildcard entries. For example, `\"*.foo.example.com\"` takes precedence over `\"*.example.com\"`. The precise definition here is that the higher the number of dots in the hostname to the right of the wildcard character, the higher the precedence. \n The wildcard character will match any number of characters _and dots_ to the left, however, so `\"*.example.com\"` will match both `\"foo.bar.example.com\"` _and_ `\"bar.example.com\"`. \n If a set of Listeners contains Listeners that are not distinct, then those Listeners are Conflicted, and the implementation MUST set the \"Conflicted\" condition in the Listener Status to \"True\". \n Implementations MAY choose to accept a Gateway with some Conflicted Listeners only if they only accept the partial Listener set that contains no Conflicted Listeners. To put this another way, implementations may accept a partial Listener set only if they throw out *all* the conflicting Listeners. No picking one of the conflicting listeners as the winner. This also means that the Gateway must have at least one non-conflicting Listener in this case, otherwise it violates the requirement that at least one Listener must be present. \n The implementation MUST set a \"ListenersNotValid\" condition on the Gateway Status when the Gateway contains Conflicted Listeners whether or not they accept the Gateway. That Condition SHOULD clearly indicate in the Message which Listeners are conflicted, and which are Accepted. Additionally, the Listener status for those listeners SHOULD indicate which Listeners are conflicted and not Accepted. \n A Gateway's Listeners are considered \"compatible\" if: \n 1. They are distinct. 2. The implementation can serve them in compliance with the Addresses requirement that all Listeners are available on all assigned addresses. \n Compatible combinations in Extended support are expected to vary across implementations. A combination that is compatible for one implementation may not be compatible for another. \n For example, an implementation that cannot serve both TCP and UDP listeners on the same address, or cannot mix HTTPS and generic TLS listens on the same port would not consider those cases compatible, even though they are distinct. \n Note that requests SHOULD match at most one Listener. For example, if Listeners are defined for \"foo.example.com\" and \"*.example.com\", a request to \"foo.example.com\" SHOULD only be routed using routes attached to the \"foo.example.com\" Listener (and not the \"*.example.com\" Listener). This concept is known as \"Listener Isolation\". Implementations that do not support Listener Isolation MUST clearly document this. \n Implementations MAY merge separate Gateways onto a single set of Addresses if all Listeners across all Gateways are compatible. \n Support: Core"

For example, a Route with a creation timestamp of \"2020-09-08 01:02:03\" is given precedence over a Route with a creation timestamp of \"2020-09-08 01:02:04\". * If everything else is equivalent, the Route appearing first in alphabetical order (namespace/name) should be given precedence. For example, foo/bar is given precedence over foo/baz. \n All valid rules within a Route attached to this Listener should be implemented. Invalid Route rules can be ignored (sometimes that will mean the full Route). If a Route rule transitions from valid to invalid, support for that Route rule should be dropped to ensure consistency.

listeners:
description: "Listeners associated with this Gateway. Listeners define logical endpoints that are bound on this Gateway's addresses. At least one Listener MUST be specified. \n Each Listener in a set of Listeners (for example, in a single Gateway) MUST be _distinct_, in that a traffic flow MUST be able to be assigned to exactly one listener. (This section uses \"set of Listeners\" rather than \"Listeners in a single Gateway\" because implementations MAY merge configuration from multiple Gateways onto a single data plane, and these rules _also_ apply in that case). \n Practically, this means that each listener in a set MUST have a unique combination of Port, Protocol, and, if supported by the protocol, Hostname. \n Some combinations of port, protocol, and TLS settings are considered Core support and MUST be supported by implementations based on their targeted conformance profile: \n HTTP Profile \n 1. HTTPRoute, Port: 80, Protocol: HTTP 2. HTTPRoute, Port: 443, Protocol: HTTPS, TLS Mode: Terminate, TLS keypair provided \n TLS Profile \n 1. TLSRoute, Port: 443, Protocol: TLS, TLS Mode: Passthrough \n \"Distinct\" Listeners have the following property: \n The implementation can match inbound requests to a single distinct Listener. When multiple Listeners share values for fields (for example, two Listeners with the same Port value), the implementation can match requests to only one of the Listeners using other Listener fields. \n For example, the following Listener scenarios are distinct: \n 1. Multiple Listeners with the same Port that all use the \"HTTP\" Protocol that all have unique Hostname values. 2. Multiple Listeners with the same Port that use either the \"HTTPS\" or \"TLS\" Protocol that all have unique Hostname values. 3. A mixture of \"TCP\" and \"UDP\" Protocol Listeners, where no Listener with the same Protocol has the same Port value. \n Some fields in the Listener struct have possible values that affect whether the Listener is distinct. Hostname is particularly relevant for HTTP or HTTPS protocols. \n When using the Hostname value to select between same-Port, same-Protocol Listeners, the Hostname value must be different on each Listener for the Listener to be distinct. \n When the Listeners are distinct based on Hostname, inbound request hostnames MUST match from the most specific to least specific Hostname values to choose the correct Listener and its associated set of Routes. \n Exact matches must be processed before wildcard matches, and wildcard matches must be processed before fallback (empty Hostname value) matches. For example, `\"foo.example.com\"` takes precedence over `\"*.example.com\"`, and `\"*.example.com\"` takes precedence over `\"\"`. \n Additionally, if there are multiple wildcard entries, more specific wildcard entries must be processed before less specific wildcard entries. For example, `\"*.foo.example.com\"` takes precedence over `\"*.example.com\"`. The precise definition here is that the higher the number of dots in the hostname to the right of the wildcard character, the higher the precedence. \n The wildcard character will match any number of characters _and dots_ to the left, however, so `\"*.example.com\"` will match both `\"foo.bar.example.com\"` _and_ `\"bar.example.com\"`. \n If a set of Listeners contains Listeners that are not distinct, then those Listeners are Conflicted, and the implementation MUST set the \"Conflicted\" condition in the Listener Status to \"True\". \n Implementations MAY choose to accept a Gateway with some Conflicted Listeners only if they only accept the partial Listener set that contains no Conflicted Listeners. To put this another way, implementations may accept a partial Listener set only if they throw out *all* the conflicting Listeners. No picking one of the conflicting listeners as the winner. This also means that the Gateway must have at least one non-conflicting Listener in this case, otherwise it violates the requirement that at least one Listener must be present. \n The implementation MUST set a \"ListenersNotValid\" condition on the Gateway Status when the Gateway contains Conflicted Listeners whether or not they accept the Gateway. That Condition SHOULD clearly indicate in the Message which Listeners are conflicted, and which are Accepted. Additionally, the Listener status for those listeners SHOULD indicate which Listeners are conflicted and not Accepted. \n A Gateway's Listeners are considered \"compatible\" if: \n 1. They are distinct. 2. The implementation can serve them in compliance with the Addresses requirement that all Listeners are available on all assigned addresses. \n Compatible combinations in Extended support are expected to vary across implementations. A combination that is compatible for one implementation may not be compatible for another. \n For example, an implementation that cannot serve both TCP and UDP listeners on the same address, or cannot mix HTTPS and generic TLS listens on the same port would not consider those cases compatible, even though they are distinct. \n Note that requests SHOULD match at most one Listener. For example, if Listeners are defined for \"foo.example.com\" and \"*.example.com\", a request to \"foo.example.com\" SHOULD only be routed using routes attached to the \"foo.example.com\" Listener (and not the \"*.example.com\" Listener). This concept is known as \"Listener Isolation\". Implementations that do not support Listener Isolation MUST clearly document this. \n Implementations MAY merge separate Gateways onto a single set of Addresses if all Listeners across all Gateways are compatible. \n Support: Core"

For example, a Route with a creation timestamp of \"2020-09-08 01:02:03\" is given precedence over a Route with a creation timestamp of \"2020-09-08 01:02:04\". * If everything else is equivalent, the Route appearing first in alphabetical order (namespace/name) should be given precedence. For example, foo/bar is given precedence over foo/baz. \n All valid rules within a Route attached to this Listener should be implemented. Invalid Route rules can be ignored (sometimes that will mean the full Route). If a Route rule transitions from valid to invalid, support for that Route rule should be dropped to ensure consistency.

hostnames:
description: "Hostnames defines a set of hostnames that should match against the HTTP Host header to select a HTTPRoute used to process the request. Implementations MUST ignore any port value specified in the HTTP Host header while performing a match and (absent of any applicable header modification configuration) MUST forward this header unmodified to the backend. \n Valid values for Hostnames are determined by RFC 1123 definition of a hostname with 2 notable exceptions: \n 1. IPs are not allowed. 2. A hostname may be prefixed with a wildcard label (`*.`). The wildcard label must appear by itself as the first label. \n If a hostname is specified by both the Listener and HTTPRoute, there must be at least one intersecting hostname for the HTTPRoute to be attached to the Listener. For example: \n * A Listener with `test.example.com` as the hostname matches HTTPRoutes that have either not specified any hostnames, or have specified at least one of `test.example.com` or `*.example.com`. * A Listener with `*.example.com` as the hostname matches HTTPRoutes that have either not specified any hostnames or have specified at least one hostname that matches the Listener hostname. For example, `*.example.com`, `test.example.com`, and `foo.test.example.com` would all match. On the other hand, `example.com` and `test.example.net` would not match. \n Hostnames that are prefixed with a wildcard label (`*.`) are interpreted as a suffix match. That means that a match for `*.example.com` would match both `test.example.com`, and `foo.test.example.com`, but not `example.com`. \n If both the Listener and HTTPRoute have specified hostnames, any HTTPRoute hostnames that do not match the Listener hostname MUST be ignored. For example, if a Listener specified `*.example.com`, and the HTTPRoute specified `test.example.com` and `test.example.net`, `test.example.net` must not be considered for a match. \n If both the Listener and HTTPRoute have specified hostnames, and none match with the criteria above, then the HTTPRoute is not accepted. The implementation must raise an 'Accepted' Condition with a status of `False` in the corresponding RouteParentStatus. \n In the event that multiple HTTPRoutes specify intersecting hostnames (e.g. overlapping wildcard matching and exact matching hostnames), precedence must be given to rules from the HTTPRoute with the largest number of: \n * Characters in a matching non-wildcard hostname. * Characters in a matching hostname. \n If ties exist across multiple Routes, the matching precedence rules for HTTPRouteMatches takes over. \n Support: Core"

parentRefs:
description: "ParentRefs references the resources (usually Gateways) that a Route wants to be attached to. Note that the referenced parent resource needs to allow this for the attachment to be complete. For Gateways, that means the Gateway needs to allow attachment from Routes of this kind and namespace. For Services, that means the Service must either be in the same namespace for a \"producer\" route, or the mesh implementation must support and allow \"consumer\" routes for the referenced Service. ReferenceGrant is not applicable for governing ParentRefs to Services - it is not possible to create a \"producer\" route for a Service in a different namespace from the Route. \n There are two kinds of parent resources with \"Core\" support: \n * Gateway (Gateway conformance profile) * Service (Mesh conformance profile, experimental, ClusterIP Services only) This API may be extended in the future to support additional kinds of parent resources. \n ParentRefs must be _distinct_. This means either that: \n * They select different objects. If this is the case, then parentRef entries are distinct. In terms of fields, this means that the multi-part key defined by `group`, `kind`, `namespace`, and `name` must be unique across all parentRef entries in the Route. * They do not select different objects, but for each optional field used, each ParentRef that selects the same object must set the same set of optional fields to different values. If one ParentRef sets a combination of optional fields, all must set the same combination. \n Some examples: \n * If one ParentRef sets `sectionName`, all ParentRefs referencing the same object must also set `sectionName`. * If one ParentRef sets `port`, all ParentRefs referencing the same object must also set `port`. * If one ParentRef sets `sectionName` and `port`, all ParentRefs referencing the same object must also set `sectionName` and `port`. \n It is possible to separately reference multiple distinct objects that may be collapsed by an implementation. For example, some implementations may choose to merge compatible Gateway Listeners together. If that is the case, the list of routes attached to those resources should also be merged. \n Note that for ParentRefs that cross namespace boundaries, there are specific rules. Cross-namespace references are only valid if they are explicitly allowed by something in the namespace they are referring to. For example, Gateway has the AllowedRoutes field, and ReferenceGrant provides a generic way to enable other kinds of cross-namespace reference. \n ParentRefs from a Route to a Service in the same namespace are \"producer\" routes, which apply default routing rules to inbound connections from any namespace to the Service. \n ParentRefs from a Route to a Service in a different namespace are \"consumer\" routes, and these routing rules are only applied to outbound connections originating from the same namespace as the Route, for which the intended destination of the connections are a Service targeted as a ParentRef of the Route. \n "

description: "Hostnames defines a set of hostnames that should match against the HTTP Host header to select a HTTPRoute used to process the request. Implementations MUST ignore any port value specified in the HTTP Host header while performing a match and (absent of any applicable header modification configuration) MUST forward this header unmodified to the backend. \n Valid values for Hostnames are determined by RFC 1123 definition of a hostname with 2 notable exceptions: \n 1. IPs are not allowed. 2. A hostname may be prefixed with a wildcard label (`*.`). The wildcard label must appear by itself as the first label. \n If a hostname is specified by both the Listener and HTTPRoute, there must be at least one intersecting hostname for the HTTPRoute to be attached to the Listener. For example: \n * A Listener with `test.example.com` as the hostname matches HTTPRoutes that have either not specified any hostnames, or have specified at least one of `test.example.com` or `*.example.com`. * A Listener with `*.example.com` as the hostname matches HTTPRoutes that have either not specified any hostnames or have specified at least one hostname that matches the Listener hostname. For example, `*.example.com`, `test.example.com`, and `foo.test.example.com` would all match. On the other hand, `example.com` and `test.example.net` would not match. \n Hostnames that are prefixed with a wildcard label (`*.`) are interpreted as a suffix match. That means that a match for `*.example.com` would match both `test.example.com`, and `foo.test.example.com`, but not `example.com`. \n If both the Listener and HTTPRoute have specified hostnames, any HTTPRoute hostnames that do not match the Listener hostname MUST be ignored. For example, if a Listener specified `*.example.com`, and the HTTPRoute specified `test.example.com` and `test.example.net`, `test.example.net` must not be considered for a match. \n If both the Listener and HTTPRoute have specified hostnames, and none match with the criteria above, then the HTTPRoute is not accepted. The implementation must raise an 'Accepted' Condition with a status of `False` in the corresponding RouteParentStatus. \n In the event that multiple HTTPRoutes specify intersecting hostnames (e.g. overlapping wildcard matching and exact matching hostnames), precedence must be given to rules from the HTTPRoute with the largest number of: \n * Characters in a matching non-wildcard hostname. * Characters in a matching hostname. \n If ties exist across multiple Routes, the matching precedence rules for HTTPRouteMatches takes over. \n Support: Core"

parentRefs:
description: "ParentRefs references the resources (usually Gateways) that a Route wants to be attached to. Note that the referenced parent resource needs to allow this for the attachment to be complete. For Gateways, that means the Gateway needs to allow attachment from Routes of this kind and namespace. For Services, that means the Service must either be in the same namespace for a \"producer\" route, or the mesh implementation must support and allow \"consumer\" routes for the referenced Service. ReferenceGrant is not applicable for governing ParentRefs to Services - it is not possible to create a \"producer\" route for a Service in a different namespace from the Route. \n There are two kinds of parent resources with \"Core\" support: \n * Gateway (Gateway conformance profile) * Service (Mesh conformance profile, experimental, ClusterIP Services only) This API may be extended in the future to support additional kinds of parent resources. \n ParentRefs must be _distinct_. This means either that: \n * They select different objects. If this is the case, then parentRef entries are distinct. In terms of fields, this means that the multi-part key defined by `group`, `kind`, `namespace`, and `name` must be unique across all parentRef entries in the Route. * They do not select different objects, but for each optional field used, each ParentRef that selects the same object must set the same set of optional fields to different values. If one ParentRef sets a combination of optional fields, all must set the same combination. \n Some examples: \n * If one ParentRef sets `sectionName`, all ParentRefs referencing the same object must also set `sectionName`. * If one ParentRef sets `port`, all ParentRefs referencing the same object must also set `port`. * If one ParentRef sets `sectionName` and `port`, all ParentRefs referencing the same object must also set `sectionName` and `port`. \n It is possible to separately reference multiple distinct objects that may be collapsed by an implementation. For example, some implementations may choose to merge compatible Gateway Listeners together. If that is the case, the list of routes attached to those resources should also be merged. \n Note that for ParentRefs that cross namespace boundaries, there are specific rules. Cross-namespace references are only valid if they are explicitly allowed by something in the namespace they are referring to. For example, Gateway has the AllowedRoutes field, and ReferenceGrant provides a generic way to enable other kinds of cross-namespace reference. \n ParentRefs from a Route to a Service in the same namespace are \"producer\" routes, which apply default routing rules to inbound connections from any namespace to the Service. \n ParentRefs from a Route to a Service in a different namespace are \"consumer\" routes, and these routing rules are only applied to outbound connections originating from the same namespace as the Route, for which the intended destination of the connections are a Service targeted as a ParentRef of the Route. \n "

name: traefik-controller
namespace: defaultThe Kubernetes Gateway API project provides several guides on how to use the APIs. These guides can help you to go further than the example above. The getting started guide details how to install the CRDs from their repository.
For now, the Traefik Gateway Provider can be used while following the below guides:
Resource Configuration¶
When using Kubernetes Gateway API as a provider, Traefik uses Kubernetes Custom Resource Definitions to retrieve its routing configuration.
All concepts can be found in the official API concepts documentation. Traefik implements the following resources:
GatewayClassdefines a set of Gateways that share a common configuration and behaviour.Gatewaydescribes how traffic can be translated to Services within the cluster.HTTPRoutedefines HTTP rules for mapping requests from a Gateway to Kubernetes Services.TCPRoutedefines TCP rules for mapping requests from a Gateway to Kubernetes Services.TLSRoutedefines TLS rules for mapping requests from a Gateway to Kubernetes Services.
Provider Configuration¶
endpoint¶
Optional, Default=""
The Kubernetes server endpoint URL.
When deployed into Kubernetes, Traefik reads the environment variables KUBERNETES_SERVICE_HOST and KUBERNETES_SERVICE_PORT or KUBECONFIG to construct the endpoint.
The access token is looked up in /var/run/secrets/kubernetes.io/serviceaccount/token and the SSL CA certificate in /var/run/secrets/kubernetes.io/serviceaccount/ca.crt.
Both are mounted automatically when deployed inside Kubernetes.
The endpoint may be specified to override the environment variable values inside a cluster.
When the environment variables are not found, Traefik tries to connect to the Kubernetes API server with an external-cluster client.
In this case, the endpoint is required.
Specifically, it may be set to the URL used by kubectl proxy to connect to a Kubernetes cluster using the granted authentication and authorization of the associated kubeconfig.
providers:
kubernetesGateway:
endpoint: "http://localhost:8080"
# ...[providers.kubernetesGateway]
endpoint = "http://localhost:8080"
# ...--providers.kubernetesgateway.endpoint=http://localhost:8080token¶
Optional, Default=""
Bearer token used for the Kubernetes client configuration.
providers:
kubernetesGateway:
token: "mytoken"
# ...[providers.kubernetesGateway]
token = "mytoken"
# ...--providers.kubernetesgateway.token=mytokencertAuthFilePath¶
Optional, Default=""
Path to the certificate authority file. Used for the Kubernetes client configuration.
providers:
kubernetesGateway:
certAuthFilePath: "/my/ca.crt"
# ...[providers.kubernetesGateway]
certAuthFilePath = "/my/ca.crt"
# ...--providers.kubernetesgateway.certauthfilepath=/my/ca.crtnamespaces¶
Optional, Default: []
Array of namespaces to watch. If left empty, Traefik watches all namespaces.
providers:
kubernetesGateway:
namespaces:
- "default"
- "production"
# ...[providers.kubernetesGateway]
namespaces = ["default", "production"]
# ...--providers.kubernetesgateway.namespaces=default,productionstatusAddress¶
ip¶
Optional, Default: ""
This IP will get copied to the Gateway status.addresses, and currently only supports one IP value (IPv4 or IPv6).
providers:
kubernetesGateway:
statusAddress:
ip: "1.2.3.4"
# ...[providers.kubernetesGateway.statusAddress]
ip = "1.2.3.4"
# ...--providers.kubernetesgateway.statusaddress.ip=1.2.3.4hostname¶
Optional, Default: ""
This Hostname will get copied to the Gateway status.addresses.
providers:
kubernetesGateway:
statusAddress:
hostname: "example.net"
# ...[providers.kubernetesGateway.statusAddress]
hostname = "example.net"
# ...--providers.kubernetesgateway.statusaddress.hostname=example.netservice¶
Optional
The Kubernetes service to copy status addresses from.
When using third parties tools like External-DNS, this option can be used to copy the service loadbalancer.status (containing the service's endpoints IPs) to the gateways.
providers:
kubernetesGateway:
statusAddress:
service:
namespace: default
name: foo
# ...[providers.kubernetesGateway.statusAddress.service]
namespace = "default"
name = "foo"
# ...--providers.kubernetesgateway.statusaddress.service.namespace=default
--providers.kubernetesgateway.statusaddress.service.name=fooexperimentalChannel¶
Optional, Default: false
Toggles support for the Experimental Channel resources (Gateway API release channels documentation).
This option currently enables support for TCPRoute and TLSRoute.
providers:
kubernetesGateway:
experimentalChannel: true[providers.kubernetesGateway]
experimentalChannel = true
# ...--providers.kubernetesgateway.experimentalchannel=truelabelselector¶
Optional, Default: ""
A label selector can be defined to filter on specific GatewayClass objects only. If left empty, Traefik processes all GatewayClass objects in the configured namespaces.
See label-selectors for details.
providers:
kubernetesGateway:
labelselector: "app=traefik"
# ...[providers.kubernetesGateway]
labelselector = "app=traefik"
# ...--providers.kubernetesgateway.labelselector="app=traefik"throttleDuration¶
Optional, Default: 0
The throttleDuration option defines how often the provider is allowed to handle events from Kubernetes. This prevents
a Kubernetes cluster that updates many times per second from continuously changing your Traefik configuration.
If left empty, the provider does not apply any throttling and does not drop any Kubernetes events.
The value of throttleDuration should be provided in seconds or as a valid duration format,
see time.ParseDuration.
providers:
kubernetesGateway:
throttleDuration: "10s"
# ...[providers.kubernetesGateway]
throttleDuration = "10s"
# ...--providers.kubernetesgateway.throttleDuration=10sUsing Traefik OSS in Production? Consider Adding Advanced Capabilities.
Add API Gateway or API Management capabilities seamlessly to your existing Traefik deployments. No rip and replace. No learning curve.
