 ## Impact
 
-### Pilot
-
-Metrics will continue to function normally up to 2.8, when they will be disabled.  
-In 2.9, the Pilot platform and all Traefik integration code will be permanently removed.
-
-Starting on 2.7 the pilot token will not be a requirement anymore for plugins.  
-Since 2.8, a [new plugin catalog](https://plugins.traefik.io) is available, decoupled from Pilot.
-
-### Consul Enterprise Namespace
-
-Starting on 2.8 the `namespace` option of Consul and Consul Catalog providers is deprecated, 
-please use the `namespaces` options instead.  
-
-### TLS 1.0 and 1.1
-
-Starting on 2.8 the default TLS options will use the minimum version of TLS 1.2. Of course, it can still be overridden with custom configuration.  
-
-### Nomad Namespace
-
-Starting on 2.10 the `namespace` option of the Nomad provider is deprecated,
-please use the `namespaces` options instead.
-
-### Kubernetes CRD Provider API Group `traefik.containo.us`

+Secure the backend connection with SPIFFE.
+{: .subtitle }
+
+[SPIFFE](https://spiffe.io/docs/latest/spiffe-about/overview/) (Secure Production Identity Framework For Everyone), 
+provides a secure identity in the form of a specially crafted X.509 certificate, 
+to every workload in an environment.
+
+Traefik is able to connect to the Workload API to obtain an x509-SVID used to secure the connection with SPIFFE enabled backends.
+
+## Configuration
+
+### General
+
+Enabling SPIFFE is part of the [static configuration](../getting-started/configuration-overview.md#the-static-configuration).
+It can be defined by using a file (YAML or TOML) or CLI arguments.
+
+### Workload API
+
+The `workloadAPIAddr` configuration defines the address of the SPIFFE [Workload API](https://spiffe.io/docs/latest/spiffe-about/spiffe-concepts/#spiffe-workload-api).
+
+!!! info "Enabling SPIFFE in ServersTransports"
+
+    Enabling SPIFFE does not imply that backend connections are going to use it automatically.
+    Each [ServersTransport](../routing/services/index.md#serverstransport_1) or [TCPServersTransport](../routing/services/index.md#serverstransport_2),
+	that is meant to be secured with SPIFFE,
+	must explicitly enable it (see [SPIFFE with ServersTransport](../routing/services/index.md#spiffe) or [SPIFFE with TCPServersTransport](../routing/services/index.md#spiffe_1)).
+
+!!! warning "SPIFFE can cause Traefik to stall"
+	When using SPIFFE,
+	Traefik will wait for the first SVID to be delivered before starting.
+	If Traefik is hanging when waiting on SPIFFE SVID delivery,
+	please double check that it is correctly registered as workload in your SPIFFE infrastructure.

+    Each router or entrypoint that is meant to use the resolver must explicitly [reference](../routing/routers/index.md#certresolver) it.

+    myresolver:

+
+## Domain Definition
+
+A certificate resolver requests certificates for a set of domain names inferred from routers, according to the following:
+
+- If the router has a [`tls.domains`](../routing/routers/index.md#domains) option set,
+  then the certificate resolver derives this router domain name from the `main` option of `tls.domains`.
+
+- Otherwise, the certificate resolver derives the domain name from any `Host()` or `HostSNI()` matchers
+  in the [router's rule](../routing/routers/index.md#rule).
+
+!!! info "Tailscale Domain Format"
+
+    The domain is only taken into account if it is a Tailscale-specific one,
+    i.e. of the form `machine-name.domains-alias.ts.net`.

 Handling Content-Type auto-detection

-The Content-Type middleware - or rather its `autoDetect` option -
-specifies whether to let the `Content-Type` header,
-if it has not been defined by the backend,
-be automatically set to a value derived from the contents of the response.
-
-As a proxy, the default behavior should be to leave the header alone,
-regardless of what the backend did with it.
-However, the historic default was to always auto-detect and set the header if it was not already defined,
-and altering this behavior would be a breaking change which would impact many users.
-
-This middleware exists to enable the correct behavior until at least the default one can be changed in a future version.
+The Content-Type middleware sets the `Content-Type` header value to the media type detected from the response content,
+when it is not set by the backend.
 
 !!! info
 
-    As explained above, for compatibility reasons the default behavior on a router (without this middleware),
-    is still to automatically set the `Content-Type` header.
-    Therefore, given the default value of the `autoDetect` option (false),
-    simply enabling this middleware for a router switches the router's behavior.
-
     The scope of the Content-Type middleware is the MIME type detection done by the core of Traefik (the server part).
     Therefore, it has no effect against any other `Content-Type` header modifications (e.g.: in another middleware such as compress).

+
+# Migration Guide: From v2 to v3
+
+How to Migrate from Traefik v2 to Traefik v3.
+{: .subtitle }
+
+The version 3 of Traefik introduces a number of breaking changes,
+which require one to update their configuration when they migrate from v2 to v3.
+The goal of this page is to recapitulate all of these changes,
+and in particular to give examples, feature by feature, 
+of how the configuration looked like in v2,
+and how it now looks like in v3.
+
+## Static configuration
+
+### Docker & Docker Swarm
+
+#### SwarmMode
+
+In v3, the provider Docker has been split into 2 providers:
+
+- Docker provider (without Swarm support)
+- Swarm provider  (Swarm support only)
+
+??? example "An example usage of v2 Docker provider with Swarm"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      docker:
+        swarmMode: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.docker]
+        swarmMode=true
+    ```
+
+    ```bash tab="CLI"
+    --providers.docker.swarmMode=true
+    ```
+
+This configuration is now unsupported and would prevent Traefik to start.
+
+##### Remediation
+
+In v3, the `swarmMode` should not be used with the Docker provider, and, to use Swarm, the Swarm provider should be used instead.
+
+??? example "An example usage of the Swarm provider"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      swarm:
+        endpoint: "tcp://127.0.0.1:2377"
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.swarm]
+        endpoint="tcp://127.0.0.1:2377"
+    ```
+
+    ```bash tab="CLI"
+    --providers.swarm.endpoint=tcp://127.0.0.1:2377
+    ```
+
+#### TLS.CAOptional
+
+Docker provider `tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+
+??? example "An example usage of the TLS.CAOptional option"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      docker:
+        tls: 
+          caOptional: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.docker.tls]
+        caOptional=true
+    ```
+
+    ```bash tab="CLI"
+    --providers.docker.tls.caOptional=true
+    ```
+
+##### Remediation
+
+The `tls.caOptional` option should be removed from the Docker provider static configuration.
+
+### Kubernetes Gateway API
+
+#### Experimental Channel Resources (TLSRoute and TCPRoute)
+
+In v3, the Kubernetes Gateway API provider does not enable support for the experimental channel API resources by default.
+
+##### Remediation
+
+The `experimentalChannel` option should be used to enable the support for the experimental channel API resources.
+
+??? example "An example usage of the Kubernetes Gateway API provider with experimental channel support enabled"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      kubernetesGateway:
+        experimentalChannel: true
+    ```
+    
+    ```toml tab="File (TOML)"
+    [providers.kubernetesGateway]
+        experimentalChannel = true
+      # ...
+    ```
+    
+    ```bash tab="CLI"
+    --providers.kubernetesgateway.experimentalchannel=true
+    ```
+
+### Experimental Configuration
+
+#### HTTP3
+
+In v3, HTTP/3 is no longer an experimental feature.
+It can be enabled on entry points without the associated `experimental.http3` option, which is now removed.
+It is now unsupported and would prevent Traefik to start.
+
+??? example "An example usage of v2 Experimental `http3` option"
+
+    ```yaml tab="File (YAML)"
+    experimental:
+      http3: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [experimental]
+        http3=true
+    ```
+
+    ```bash tab="CLI"
+    --experimental.http3=true
+    ```
+
+##### Remediation
+
+The `http3` option should be removed from the static configuration experimental section.
+
+### Consul provider
+
+#### namespace
+
+The Consul provider `namespace` option was deprecated in v2 and is now removed in v3.
+It is now unsupported and would prevent Traefik to start.
+
+??? example "An example usage of v2 Consul `namespace` option"
+
+    ```yaml tab="File (YAML)"
+    consul:
+      namespace: foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [consul]
+        namespace=foobar
+    ```
+
+    ```bash tab="CLI"
+    --consul.namespace=foobar
+    ```
+
+##### Remediation
+
+In v3, the `namespaces` option should be used instead of the `namespace` option.
+
+??? example "An example usage of Consul `namespaces` option"
+
+    ```yaml tab="File (YAML)"
+    consul:
+      namespaces:
+        - foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [consul]
+        namespaces=["foobar"]
+    ```
+
+    ```bash tab="CLI"
+    --consul.namespaces=foobar
+    ```
+
+#### TLS.CAOptional
+
+Consul provider `tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+

+
+### Rancher v1 Provider
+
+In v3, the Rancher v1 provider has been removed because Rancher v1 is [no longer actively maintained](https://rancher.com/docs/os/v1.x/en/support/),
+and Rancher v2 is supported as a standard Kubernetes provider.
+
+??? example "An example of Traefik v2 Rancher v1 configuration"

+    ```bash tab="CLI"
+    --providers.rancher=true
+    ```
+
+This configuration is now unsupported and would prevent Traefik to start.
+
+#### Remediation
+
+Rancher 2.x requires Kubernetes and does not have a metadata endpoint of its own for Traefik to query.
+As such, Rancher 2.x users should utilize the [Kubernetes CRD provider](../providers/kubernetes-crd.md) directly.
+
+Also, all Rancher provider related configuration should be removed from the static configuration.
+
+### Marathon provider
+
+Marathon maintenance [ended on October 31, 2021](https://github.com/mesosphere/marathon/blob/master/README.md).
+In v3, the Marathon provider has been removed.

+
+#### Remediation
+
+All Marathon provider related configuration should be removed from the static configuration.
+
+### HTTP Provider
+
+#### TLS.CAOptional
+
+HTTP provider `tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).

+### InfluxDB v1
+
+InfluxDB v1.x maintenance [ended in 2021](https://www.influxdata.com/blog/influxdb-oss-and-enterprise-roadmap-update-from-influxdays-emea/).
+In v3, the InfluxDB v1 metrics provider has been removed.
+
+??? example "An example of Traefik v2 InfluxDB v1 metrics configuration"
+
+    ```yaml tab="File (YAML)"
+    metrics:
+      influxDB: {}
+    ```

+    ```
+
+    ```bash tab="CLI"
+    --metrics.influxDB=true
+    ```
+
+This configuration is now unsupported and would prevent Traefik to start.
+
+#### Remediation
+
+All InfluxDB v1 metrics provider related configuration should be removed from the static configuration.
+
+### Pilot
+
+Traefik Pilot is no longer available since October 4th, 2022.
+
+??? example "An example of v2 Pilot configuration"
+
+    ```yaml tab="File (YAML)"
+    pilot:
+      token: foobar
+    ```

+        token=foobar
+    ```
+
+    ```bash tab="CLI"
+    --pilot.token=foobar
+    ```
+
+In v2, Pilot configuration was deprecated and ineffective,
+it is now unsupported and would prevent Traefik to start.
+
+#### Remediation
+
+All Pilot related configuration should be removed from the static configuration.
+
+## Dynamic configuration
+
+### Router Rule Matchers
+
+In v3, a new rule matchers syntax has been introduced for HTTP and TCP routers.
+The default rule matchers syntax is now the v3 one, but for backward compatibility this can be configured.
+The v2 rule matchers syntax is deprecated and its support will be removed in the next major version.
+For this reason, we encourage migrating to the new syntax.
+
+By default, the `defaultRuleSyntax` static option is automatically set to `v3`, meaning that the default rule is the new one.
+
+#### New V3 Syntax Notable Changes
+
+The `Headers` and `HeadersRegexp` matchers have been renamed to `Header` and `HeaderRegexp` respectively.
+
+`PathPrefix` no longer uses regular expressions to match path prefixes.
+
+`QueryRegexp` has been introduced to match query values using a regular expression.
+
+`HeaderRegexp`, `HostRegexp`, `PathRegexp`, `QueryRegexp`, and `HostSNIRegexp` matchers now uses the [Go regexp syntax](https://golang.org/pkg/regexp/syntax/).
+
+All matchers now take a single value (except `Header`, `HeaderRegexp`, `Query`, and `QueryRegexp` which take two)
+and should be explicitly combined using logical operators to mimic previous behavior.
+
+`Query` can take a single value to match is the query value that has no value (e.g. `/search?mobile`).
+
+`HostHeader` has been removed, use `Host` instead.
+
+#### Remediation
+
+##### Configure the Default Syntax In Static Configuration
+
+The default rule matchers syntax is the expected syntax for any router that is not self opt-out from this default value.
+It can be configured in the static configuration.
+
+??? example "An example configuration for the default rule matchers syntax"
+
+    ```yaml tab="File (YAML)"
+    # static configuration
+    core:
+      defaultRuleSyntax: v2
+    ```
+
+    ```toml tab="File (TOML)"
+    # static configuration
+    [core]
+        defaultRuleSyntax="v2"
+    ```
+
+    ```bash tab="CLI"
+    # static configuration
+    --core.defaultRuleSyntax=v2
+    ```
+
+##### Configure the Syntax Per Router
+
+The rule syntax can also be configured on a per-router basis.
+This allows to have heterogeneous router configurations and ease migration.
+
+??? example "An example router with syntax configuration"
+
+```yaml tab="Docker & Swarm"
+labels:
+  - "traefik.http.routers.test.ruleSyntax=v2"
+```
+
+```yaml tab="Kubernetes"
+apiVersion: traefik.io/v1alpha1
+kind: IngressRoute
+metadata:
+  name: test.route
+  namespace: default
+
+spec:
+  routes:
+    - match: PathPrefix(`/foo`, `/bar`)
+      syntax: v2
+      kind: Rule
+```
+
+```yaml tab="Consul Catalog"
+- "traefik.http.routers.test.ruleSyntax=v2"
+```
+
+```yaml tab="File (YAML)"
+http:
+  routers:
+    test:
+      ruleSyntax: v2
+```
+
+```toml tab="File (TOML)"
+[http.routers]
+  [http.routers.test]
+    ruleSyntax = "v2"
+```
+
+### IPWhiteList
+
+In v3, we renamed the `IPWhiteList` middleware to `IPAllowList` without changing anything to the configuration. 
+
+### Deprecated Options Removal
+
+- The `tracing.datadog.globaltag` option has been removed.
+- The `tls.caOptional` option has been removed from the ForwardAuth middleware, as well as from the HTTP, Consul, Etcd, Redis, ZooKeeper, Consul Catalog, and Docker providers.
+- `sslRedirect`, `sslTemporaryRedirect`, `sslHost`, `sslForceHost` and `featurePolicy` options of the Headers middleware have been removed.
+- The `forceSlash` option of the StripPrefix middleware has been removed.
+- The `preferServerCipherSuites` option has been removed.
+
+### TCP LoadBalancer `terminationDelay` option
+
+The TCP LoadBalancer `terminationDelay` option has been removed.
+This option can now be configured directly on the `TCPServersTransport` level, please take a look at this [documentation](../routing/services/index.md#terminationdelay)
+
+### Kubernetes CRDs API Group `traefik.containo.us`
+
+In v3, the Kubernetes CRDs API Group `traefik.containo.us` has been removed. 
+Please use the API Group `traefik.io` instead.
+
+### Kubernetes Ingress API Group `networking.k8s.io/v1beta1`
+
+In v3, the Kubernetes Ingress API Group `networking.k8s.io/v1beta1` ([removed since Kubernetes v1.22](https://kubernetes.io/docs/reference/using-api/deprecation-guide/#ingress-v122)) support has been removed.
+
+Please use the API Group `networking.k8s.io/v1` instead.
+
+### Traefik CRD API Version `apiextensions.k8s.io/v1beta1`
+
+In v3, the Traefik CRD API Version `apiextensions.k8s.io/v1beta1` ([removed since Kubernetes v1.22](https://kubernetes.io/docs/reference/using-api/deprecation-guide/#customresourcedefinition-v122)) support has been removed.
+
+Please use the CRD definition with the API Version `apiextensions.k8s.io/v1` instead.
+
+## Operations
+
+### Traefik RBAC Update
+
+In v3, the support of `TCPServersTransport` has been introduced.
+When using the KubernetesCRD provider, it is therefore necessary to update [RBAC](../reference/dynamic-configuration/kubernetes-crd.md#rbac) and [CRD](../reference/dynamic-configuration/kubernetes-crd.md) manifests.
+
+### Content-Type Auto-Detection
+
+In v3, the `Content-Type` header is not auto-detected anymore when it is not set by the backend.
+One should use the `ContentType` middleware to enable the `Content-Type` header value auto-detection.
+
+### Observability
+
+#### gRPC Metrics
+
+In v3, the reported status code for gRPC requests is now the value of the `Grpc-Status` header.  
+
+#### Tracing
+
+In v3, the tracing feature has been revamped and is now powered exclusively by [OpenTelemetry](https://opentelemetry.io/ "Link to website of OTel") (OTel).
+!!! warning "Important"
+
+    Traefik v3 **no** longer supports direct output formats for specific vendors such as Instana, Jaeger, Zipkin, Haystack, Datadog, and Elastic.
+Instead, it focuses on pure OpenTelemetry implementation, providing a unified and standardized approach for observability.
+
+Here are two possible transition strategies:
+
+1. OTLP Ingestion Endpoints:
+
+    Most vendors now offer OpenTelemetry Protocol (OTLP) ingestion endpoints.
+    You can seamlessly integrate Traefik v3 with these endpoints to continue leveraging tracing capabilities.
+
+2. Legacy Stack Compatibility:
+
+    For legacy stacks that cannot immediately upgrade to the latest vendor agents supporting OTLP ingestion,
+    using OpenTelemetry (OTel) collectors with appropriate exporters configuration is a viable solution.
+    This allows continued compatibility with the existing infrastructure.
+
+Please check the [OpenTelemetry Tracing provider documention](../observability/tracing/opentelemetry.md) for more information.
+
+#### Internal Resources Observability
+
+In v3, observability for internal routers or services (e.g.: `ping@internal`) is disabled by default.
+To enable it one should use the new `addInternals` option for AccessLogs, Metrics or Tracing.
+Please take a look at the observability documentation for more information:
+
+- [AccessLogs](../observability/access-logs.md#addinternals)
+- [Metrics](../observability/metrics/overview.md#addinternals)
+- [Tracing](../observability/tracing/overview.md#addinternals)

+# Overview
+
+Traefik's Observability system
+{: .subtitle }
+
+## Logs
+
+Traefik logs informs about everything that happens within Traefik (startup, configuration, events, shutdown, and so on).
+
+Read the [Logs documentation](./logs.md) to learn how to configure it.
+
+## Access Logs
+
+Access logs are a key part of observability in Traefik.
+
+They are providing valuable insights about incoming traffic, and allow to monitor it.
+The access logs record detailed information about each request received by Traefik,
+including the source IP address, requested URL, response status code, and more.
+
+Read the [Access Logs documentation](./access-logs.md) to learn how to configure it.
+
+## Metrics
+
+Traefik offers a metrics feature that provides valuable insights about the performance and usage.
+These metrics include the number of requests received, the requests duration, and more.
+
+Traefik supports these metrics systems: Prometheus, Datadog, InfluxDB 2.X, and StatsD.
+
+Read the [Metrics documentation](./metrics/overview.md) to learn how to configure it.
+
+## Tracing
+
+The Traefik tracing system allows developers to gain deep visibility into the flow of requests through their infrastructure.
+
+Traefik supports these tracing with OpenTelemetry.
+
+Read the [Tracing documentation](./tracing/overview.md) to learn how to configure it.

-## Docker Swarm Mode
-
-To enable Docker Swarm (instead of standalone Docker) as a configuration provider,
-set the [`swarmMode`](#swarmmode) directive to `true`.
-
-### Routing Configuration with Labels
-
-While in Swarm Mode, Traefik uses labels found on services, not on individual containers.
-
-Therefore, if you use a compose file with Swarm Mode, labels should be defined in the
-[`deploy`](https://docs.docker.com/compose/compose-file/compose-file-v3/#labels-1) part of your service.
-
-This behavior is only enabled for docker-compose version 3+ ([Compose file reference](https://docs.docker.com/compose/compose-file/compose-file-v3/)).
-
-### Port Detection
-
-Docker Swarm does not provide any [port detection](#port-detection) information to Traefik.
-
-Therefore, you **must** specify the port to use for communication by using the label `traefik.http.services.<service_name>.loadbalancer.server.port`
-(Check the reference for this label in the [routing section for Docker](../routing/providers/docker.md#port)).
-
-### Docker API Access
-
-Docker Swarm Mode follows the same rules as Docker [API Access](#docker-api-access).
-
-Since the Swarm API is only exposed on the [manager nodes](https://docs.docker.com/engine/swarm/how-swarm-mode-works/nodes/#manager-nodes),
-these are the nodes that Traefik should be scheduled on by deploying Traefik with a constraint on the node "role":
-
-```shell tab="With Docker CLI"
-docker service create \
-  --constraint=node.role==manager \
-  #... \
-```
-
-```yml tab="With Docker Compose"
-version: '3'
-
-services:
-  traefik:
-    # ...
-    deploy:
-      placement:
-        constraints:
-          - node.role == manager
-```
-
-!!! tip "Scheduling Traefik on Worker Nodes"
-
-    Following the guidelines given in the previous section ["Docker API Access"](#docker-api-access),
-    if you expose the Docker API through TCP, then Traefik can be scheduled on any node if the TCP
-    socket is reachable.
-
-    Please consider the security implications by reading the [Security Note](#security-note).
-
-    A good example can be found on [Bret Fisher's repository](https://github.com/BretFisher/dogvscat/blob/master/stack-proxy-global.yml#L124).

-### `constraints`
-
-_Optional, Default=""_
-
-The `constraints` option can be set to an expression that Traefik matches against the application labels to determine whether
-to create any route for that application. If none of the application labels match the expression, no route for that application is
-created. In addition, the expression is also matched against the application constraints, such as described
-in [Marathon constraints](https://mesosphere.github.io/marathon/docs/constraints.html).
-If the expression is empty, all detected applications are included.
-
-The expression syntax is based on the `Label("key", "value")`, and `LabelRegex("key", "value")` functions, as well as the usual boolean logic.
-In addition, to match against Marathon constraints, the function `MarathonConstraint("field:operator:value")` can be used, where the field, operator, and value parts are concatenated in a single string using the `:` separator.

-
-Attach labels to your services and let Traefik do the rest!
-
-!!! important "This provider is specific to Rancher 1.x."
-
-    Rancher 2.x requires Kubernetes and does not have a metadata endpoint of its own for Traefik to query.
-    As such, Rancher 2.x users should utilize the [Kubernetes CRD provider](./kubernetes-crd.md) directly.
-
-## Configuration Examples
-
-??? example "Configuring Rancher & Deploying / Exposing Services"
-
-    Enabling the Rancher provider
-
-    ```yaml tab="File (YAML)"
-    providers:
-      rancher: {}
-    ```
-
-    ```toml tab="File (TOML)"

-## Routing Configuration
-
-See the dedicated section in [routing](../routing/providers/rancher.md).
-
-## Provider Configuration
-
-??? tip "Browse the Reference"
-
-    For an overview of all the options that can be set with the Rancher provider, see the following snippets:
-
-    ```yaml tab="File (YAML)"
-    --8<-- "content/providers/rancher.yml"

-
-### `exposedByDefault`
-
-_Optional, Default=true_
-
-Expose Rancher services by default in Traefik.
-If set to `false`, services that do not have a `traefik.enable=true` label are ignored from the resulting routing configuration.
-
-For additional information, refer to [Restrict the Scope of Service Discovery](./overview.md#restrict-the-scope-of-service-discovery).

-```
-
-```bash tab="CLI"
---providers.rancher.exposedByDefault=false
-# ...
-```
-
-### `defaultRule`
-
-_Optional, Default=```Host(`{{ normalize .Name }}`)```_
-
-The default host rule for all services.
-
-The `defaultRule` option defines what routing rule to apply to a container if no rule is defined by a label.
-
-It must be a valid [Go template](https://pkg.go.dev/text/template/), and can use
-[sprig template functions](https://masterminds.github.io/sprig/).
-The service name can be accessed with the `Name` identifier,
-and the template has access to all the labels defined on this container.
-
-This option can be overridden on a container basis with the `traefik.http.routers.Router1.rule` label.
-
-```yaml tab="File (YAML)"
-providers:
-  rancher:
-    defaultRule: "Host(`{{ .Name }}.{{ index .Labels \"customLabel\"}}`)"

-```bash tab="CLI"
---providers.rancher.defaultRule=Host(`{{ .Name }}.{{ index .Labels \"customLabel\"}}`)
-# ...
-```
-
-??? info "Default rule and Traefik service"
-
-    The exposure of the Traefik container, combined with the default rule mechanism,
-    can lead to create a router targeting itself in a loop.
-    In this case, to prevent an infinite loop,
-    Traefik adds an internal middleware to refuse the request if it comes from the same router.
-
-### `enableServiceHealthFilter`
-
-_Optional, Default=true_
-
-Filter out services with unhealthy states and inactive states.
-
-```yaml tab="File (YAML)"
-providers:
-  rancher:
-    enableServiceHealthFilter: false
-    # ...
-```
-
-```toml tab="File (TOML)"

-  enableServiceHealthFilter = false
-  # ...
-```
-
-```bash tab="CLI"
---providers.rancher.enableServiceHealthFilter=false
-# ...
-```
-
-### `refreshSeconds`
-
-_Optional, Default=15_
-
-Defines the polling interval (in seconds).
-
-```yaml tab="File (YAML)"
-providers:
-  rancher:
-    refreshSeconds: 30
-    # ...
-```
-
-```toml tab="File (TOML)"
-[providers.rancher]
-  refreshSeconds = 30
-  # ...
-```
-
-```bash tab="CLI"
---providers.rancher.refreshSeconds=30
-# ...
-```
-
-### `intervalPoll`
-
-_Optional, Default=false_
-
-Poll the Rancher metadata service for changes every `rancher.refreshSeconds`,
-which is less accurate than the default long polling technique which provides near instantaneous updates to Traefik.
-
-```yaml tab="File (YAML)"
-providers:
-  rancher:
-    intervalPoll: true
-    # ...
-```
-
-```toml tab="File (TOML)"
-[providers.rancher]
-  intervalPoll = true
-  # ...
-```
-
-```bash tab="CLI"
---providers.rancher.intervalPoll=true
-# ...
-```
-
-### `prefix`
-
-_Optional, Default="/latest"_
-
-Prefix used for accessing the Rancher metadata service.
-
-```yaml tab="File (YAML)"
-providers:
-  rancher:
-    prefix: "/test"
-    # ...
-```
-
-```toml tab="File (TOML)"
-[providers.rancher]
-  prefix = "/test"
-  # ...
-```
-
-```bash tab="CLI"
---providers.rancher.prefix=/test
-# ...
-```
-
-### `constraints`
-
-_Optional, Default=""_
-
-The `constraints` option can be set to an expression that Traefik matches against the container labels to determine whether
-to create any route for that container. If none of the container tags match the expression, no route for that container is
-created. If the expression is empty, all detected containers are included.
-
-The expression syntax is based on the `Label("key", "value")`, and `LabelRegex("key", "value")` functions, as well as
-the usual boolean logic, as shown in examples below.
-
-??? example "Constraints Expression Examples"
-
-    ```toml
-    # Includes only containers having a label with key `a.label.name` and value `foo`
-    constraints = "Label(`a.label.name`, `foo`)"
-    ```
-
-    ```toml
-    # Excludes containers having any label with key `a.label.name` and value `foo`
-    constraints = "!Label(`a.label.name`, `value`)"
-    ```
-
-    ```toml
-    # With logical AND.
-    constraints = "Label(`a.label.name`, `valueA`) && Label(`another.label.name`, `valueB`)"
-    ```
-
-    ```toml
-    # With logical OR.
-    constraints = "Label(`a.label.name`, `valueA`) || Label(`another.label.name`, `valueB`)"
-    ```
-
-    ```toml
-    # With logical AND and OR, with precedence set by parentheses.
-    constraints = "Label(`a.label.name`, `valueA`) && (Label(`another.label.name`, `valueB`) || Label(`yet.another.label.name`, `valueC`))"
-    ```
-
