 This will create binaries for the Linux platform in the `dist` folder.
 
 In case when you run build on CI, you may probably want to run docker in non-interactive mode. To achieve that define `DOCKER_NON_INTERACTIVE=true` environment variable.

-## 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.  
+There is no feature deprecation in Traefik v3 for now.

+# SPIFFE
+
+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.

+title: "Traefik Tailscale Documentation"
+description: "Learn how to configure Traefik Proxy to resolve TLS certificates for your Tailscale services. Read the technical documentation."
+---
+
+# Tailscale
+
+Provision TLS certificates for your internal Tailscale services.
+{: .subtitle }
+
+To protect a service with TLS, a certificate from a public Certificate Authority is needed.
+In addition to its vpn role, Tailscale can also [provide certificates](https://tailscale.com/kb/1153/enabling-https/) for the machines in your Tailscale network.
+
+## Certificate resolvers
+
+To obtain a TLS certificate from the Tailscale daemon,
+a Tailscale certificate resolver needs to be configured as below.
+
+!!! info "Referencing a certificate resolver"
+
+    Defining a certificate resolver does not imply that routers are going to use it automatically.
+    Each router or entrypoint that is meant to use the resolver must explicitly [reference](../routing/routers/index.md#certresolver) it.
+
+```yaml tab="File (YAML)"
+certificatesResolvers:
+    myresolver:
+        tailscale: {}
+```
+
+```toml tab="File (TOML)"
+[certificatesResolvers.myresolver.tailscale]
+```
+
+```bash tab="CLI"
+--certificatesresolvers.myresolver.tailscale=true
+```
+
+## 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`.
+
+## Configuration Example

+and starts to renew a certificate 14 days before its expiry to match Tailscale daemon renew policy.

 Handling Content-Type auto-detection
 {: .subtitle }
 
-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).

+description: "Migrate from Traefik Proxy v2 to v3 and update all the necessary configurations to take advantage of all the improvements. Read the technical documentation."
+---
+
+# 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.
+
+## IPWhiteList
+
+In v3, we renamed the `IPWhiteList` middleware to `IPAllowList` without changing anything to the configuration. 
+
+## gRPC Metrics
+
+In v3, the reported status code for gRPC requests is now the value of the `Grpc-Status` header.  
+
+## Deprecated Options Removal
+
+- The `pilot` option has been removed from the static configuration.
+- The `tracing.datadog.globaltag` option has been removed.
+- The `namespace` option of Consul, Consul Catalog and Nomad providers 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.
+
+## Matchers
+
+In v3, the `Headers` and `HeadersRegexp` matchers have been renamed to `Header` and `HeaderRegexp` respectively.
+
+`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 `Headers`, `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.
+
+## 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.
+
+## HTTP/3
+
+In v3, HTTP/3 is no longer an experimental feature.
+The `experimental.http3` option has been removed from the static configuration.
+
+## TCP ServersTransport
+
+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.
+
+### 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)
+
+## Rancher v1
+
+In v3, the rancher v1 provider has been removed because Rancher v1 is [no longer actively maintaned](https://rancher.com/docs/os/v1.x/en/support/) and v2 is supported as a standard Kubernetes provider.
+
+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.
+
+## Marathon provider
+
+In v3, the Marathon provider has been removed.
+
+## InfluxDB v1
+
+In v3, the InfluxDB v1 metrics provider has been removed because InfluxDB v1.x maintenance [ended in 2021](https://www.influxdata.com/blog/influxdb-oss-and-enterprise-roadmap-update-from-influxdays-emea/).

 ## Log Rotation
 
-Traefik will close and reopen its log files, assuming they're configured, on receipt of a USR1 signal.
-This allows the logs to be rotated and processed by an external program, such as `logrotate`.
+The rotation of the log files can be configured with the following options.
 
-!!! warning
-    This does not work on Windows due to the lack of USR signals.
+### `maxSize`
+
+`maxSize` is the maximum size in megabytes of the log file before it gets rotated.
+It defaults to 100 megabytes.
+
+```yaml tab="File (YAML)"
+log:
+  maxSize: 1

+
+### `maxAge`
+
+`maxAge` is the maximum number of days to retain old log files based on the timestamp encoded in their filename.
+Note that a day is defined as 24 hours and may not exactly correspond to calendar days due to daylight savings, leap seconds, etc.
+The default is not to remove old log files based on age.

-
-### `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.

-# Traefik & Rancher
-
-A Story of Labels, Services & Containers
-{: .subtitle }
-
-![Rancher](../assets/img/providers/rancher.png)
-
-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)"
-    [providers.rancher]
-    ```
-
-    ```bash tab="CLI"
-    --providers.rancher=true
-    ```
-
-    Attaching labels to services
-
-    ```yaml
-    labels:
-      - traefik.http.services.my-service.rule=Host(`example.com`)
-    ```
-
-## 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"
-    ```
-
-    ```toml tab="File (TOML)"
-    --8<-- "content/providers/rancher.toml"
-    ```
-
-    ```bash tab="CLI"
-    --8<-- "content/providers/rancher.txt"
-    ```
-
-### `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).
-
-```yaml tab="File (YAML)"
-providers:
-  rancher:
-    exposedByDefault: false
-    # ...
-```
-
-```toml tab="File (TOML)"
-[providers.rancher]
-  exposedByDefault = false
-  # ...
-```
-
-```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\"}}`)"
-    # ...
-```
-
-```toml tab="File (TOML)"
-[providers.rancher]
-  defaultRule = "Host(`{{ .Name }}.{{ index .Labels \"customLabel\"}}`)"
-  # ...
-```
-
-```bash tab="CLI"
---providers.rancher.defaultRule=Host(`{{ .Name }}.{{ index .Labels \"customLabel\"}}`)
-# ...
-```
-
-### `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)"
-[providers.rancher]
-  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`))"
-    ```
-
-    ```toml
-    # Includes only containers having a label with key `a.label.name` and a value matching the `a.+` regular expression.
-    constraints = "LabelRegex(`a.label.name`, `a.+`)"
-    ```
