 Welcome to the Traefik Community.
-This document describes how to be part of the core team
-as well as various responsibilities
-and guidelines for Traefik maintainers.
+
 We are strongly promoting a philosophy of openness and sharing,
 and firmly standing against the elitist closed approach.
 Being part of the core team should be accessible to anyone motivated
 and wants to be part of that journey!
 
-## Onboarding Process
+## Becoming a Maintainer
 
-If you consider joining our community please drop us a line using Twitter or leave a note in the issue.
-We will schedule a quick call to meet you and learn more about your motivation.
-During the call, the team will discuss the process of becoming a maintainer.
-We will be happy to answer any questions and explain all your doubts.
+Before a contributor becomes a maintainer, they should meet the following requirements:
 
-## Maintainer's Requirements
+- The contributor enabled [2FA](https://docs.github.com/en/authentication/securing-your-account-with-two-factor-authentication-2fa/configuring-two-factor-authentication) on their GitHub account
 
-Note: you do not have to meet all the listed requirements,
-but must have achieved several.
+- The contributor showed a consistent pattern of helpful, non-threatening, and friendly behavior towards other community members in the past.
+
+- The contributor has read and accepted the maintainer's guidelines.
+
+The contributor should also meet one or several of the following requirements:
 
-- Enabled [2FA](https://docs.github.com/en/authentication/securing-your-account-with-two-factor-authentication-2fa/configuring-two-factor-authentication) on your GitHub account
 - The contributor has opened and successfully run medium to large PR’s in the past 6 months.
+
 - The contributor has participated in multiple code reviews of other PR’s,
   including those of other maintainers and contributors.
-- The contributor showed a consistent pattern of helpful, non-threatening, and friendly behavior towards other community members in the past.
+
 - The contributor is active on Traefik Community forums
   or other technical forums/boards such as K8S slack, Reddit, StackOverflow, hacker news.
-- Have read and accepted the contributor guidelines.
+
+Any existing active maintainer can create an issue to discuss promoting a contributor to maintainer. 
+Other maintainers can vote on the issue, and if the quorum is reached, the contributor is promoted to maintainer.
+If the quorum is not reached within one month after the issue is created, it is closed.
 
 ## Maintainer's Responsibilities and Privileges
 
-There are lots of areas where you can contribute to the project,
-but we can suggest you start with activities such as:
+As a maintainer, you are granted a vote for the following:
 
-- PR reviewing.
-    - According to our guidelines we require you have at least 3 reviewers,
-      thus you can review a PR and leave the relevant comment if it is necessary.
-- Participating in a daily [issue triage](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md).
-    - The process helps to understand and prioritize the reported issue according to its importance and severity.
-      This is crucial to learn how our users implement Traefik.
-      Each of the issues that are labeled as bug/possible bug/confirmed requires a reproducible use case. 
-      You can help in creating a reproducible use case if it has not been added to the issue
-      or use the sample code provided by the reporter.
-      Typically, a simple docker compose should be enough to reproduce the issue.
-- Code contribution.
-- Documentation contribution.
-    - Technical documentation is one of the most important components of the product.
-      The ability to set up a testing environment in a few minutes,
-      using the official documentation,
-      is a game changer.
-- You will be listed on our Maintainers GitHub page
-  as well as on our website in the section [maintainers](maintainers.md).
-- We will be promoting you on social channels (mostly on Twitter).

-- Roadmap meetings on a regular basis where all maintainers are welcome.
+- [Proposals](https://github.com/traefik/contributors-guide/blob/master/proposals.md).
+
+Maintainers are also added to the maintainer's Discord server where happens the [issue triage](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md)
+and appear on the [Maintainers](maintainers.md) page.
+
+As a maintainer, you should: 
+
+- Prioritize PR reviews, design reviews, and issue triage above any other task. 
+
+Making sure contributors and community members are listened to and have an impact on the project is essential to keeping the project active and develop a thriving community.
+
+- Prioritize helping contributors reaching the expecting quality level over rewriting contributions.
+
+Any triage activity on issues and PRs (e.g. labels, marking messages as off-topic, refusing, marking duplicates) should result from a collective decision to ensure knowledge is shared among maintainers.
 
 ## Communicating
 
-- All of our maintainers are added to Slack #traefik-maintainers channel that belongs to Traefik labs workspace.

+  Having the team in one place helps us to communicate effectively.
+  Maintainers can discuss issues, pull requests, enhancements more efficiently
   and get the feedback almost immediately.
   Fewer blockers mean more fun and engaging work.
 
-- On a daily basis, we publish a report that includes all the activities performed during the day.
-  You are updated in regard to the workload that has been processed including:
-  working on the new features and enhancements,
-  activities related to the reported issues and PR’s,
-  other important project-related announcements.
+- Every decision made on the discord server among maintainers is documented so it's visible to the rest of the community.
 
-- At 5:00 PM CET every day we review all the created issues that have been reported,
-  assign them the appropriate *[labels](maintainers.md#labels)*
-  and prioritize them based on the severity of the problem.
-  The process is called *[issue triaging](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md)*.
-  Each of the maintainers is welcome to join the meeting.
-  For that purpose, we use a dedicated Discord server
-  where you are invited once you have become the official maintainer.
+- Maintainers express their opinions on issues and reviews. 
+  It is fine to have different point of views. 
+  We encourage active and open conversations which goals are to improve Traefik.

-### Pilot
+### Kubernetes CRDs API Version `traefik.io/v1alpha1`
 
-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.
+The newly introduced Kubernetes CRD API Version `traefik.io/v1alpha1` will subsequently be removed in Traefik v3. The following version will be `traefik.io/v1`.
 
-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.
+### Kubernetes Ingress API Version `networking.k8s.io/v1beta1`
 
-### Consul Enterprise Namespace
+The Kubernetes Ingress API Version `networking.k8s.io/v1beta1` is removed in v3. Please use the API Group `networking.k8s.io/v1` instead.
 
-Starting on 2.8 the `namespace` option of Consul and Consul Catalog providers is deprecated, 
-please use the `namespaces` options instead.  
+### Traefik CRD API Version `apiextensions.k8s.io/v1beta1`
 
-### 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.  
+The Traefik CRD API Version `apiextensions.k8s.io/v1beta1` is removed in v3. Please use the API Group `apiextensions.k8s.io/v1` instead.

 # Concepts
 
-Everything You Need to Know
-{: .subtitle }
+This page explains the base concepts of Traefik.
+
+---
+
+## Introduction
+
+Traefik is based on the concept of EntryPoints, Routers, Middlewares and Services.
+
+The main features include dynamic configuration, automatic service discovery, and support for multiple backends and protocols.
+
+1. [EntryPoints](../routing/entrypoints.md "Link to docs about EntryPoints"): EntryPoints are the network entry points into Traefik. They define the port which will receive the packets, and whether to listen for TCP or UDP.
+
+2. [Routers](../routing/routers/index.md "Link to docs about routers"): A router is in charge of connecting incoming requests to the services that can handle them.
+
+3. [Middlewares](../middlewares/overview.md "Link to docs about middlewares"): Attached to the routers, middlewares can modify the requests or responses before they are sent to your service
+
+4. [Services](../routing/services/index.md "Link to docs about services"): Services are responsible for configuring how to reach the actual services that will eventually handle the incoming requests.
 
 ## Edge Router
 
-Traefik is an _Edge Router_, it means that it's the door to your platform, and that it intercepts and routes every incoming request:
-it knows all the logic and every rule that determine which services handle which requests (based on the [path](../routing/routers/index.md#rule), the [host](../routing/routers/index.md#rule), [headers](../routing/routers/index.md#rule), [and so on](../routing/routers/index.md#rule) ...).

+## How Traefik is Storing and Serving TLS Certificates?
+
+### Storing TLS Certificates
+
+[TLS](../https/tls.md "Link to Traefik TLS docs") certificates are either provided directly by the [dynamic configuration](./configuration-overview.md#the-dynamic-configuration "Link to dynamic configuration overview") from [providers](../https/tls.md#user-defined "Link to the TLS configuration"),
+or by [ACME resolvers](../https/acme.md#providers "Link to ACME resolvers"), which act themselves as providers internally.
+
+For each TLS certificate, Traefik produces an identifier used as a key to store it.
+This identifier is constructed as the alphabetically ordered concatenation of the SANs `DNSNames` and `IPAddresses` of the TLScertificate.
+
+#### Examples:
+
+| X509v3 Subject Alternative Name         | TLS Certificate Identifier  |
+|-----------------------------------------|-----------------------------|
+| `DNS:example.com, IP Address:127.0.0.1` | `127.0.0.1,example.com`     |
+| `DNS:example.com, DNS:*.example.com`    | `*.example.com,example.com` |
+
+The identifier is used to store TLS certificates in order to be later used to handle TLS connections.
+This operation happens each time there are configuration changes.
+
+If multiple TLS certificates are provided with the same SANs definition (same identifier), only the one processed first is kept.
+Because the dynamic configuration is aggregated from all providers,
+when processing it to gather TLS certificates,
+there is no guarantee of the order in which they would be processed.
+This means that along with configurations applied, it is possible that the TLS certificate retained for a given identifier differs.
+
+### Serving TLS Certificates
+
+For each incoming connection, Traefik is serving the "best" matching TLS certificate for the provided server name.
+
+The TLS certificate selection process narrows down the list of TLS certificates matching the server name,
+and then selects the last TLS certificate in this list after having ordered it by the identifier alphabetically.
+
+#### Examples:
+
+| Selected TLS Certificates Identifiers               | Sorted TLS Certificates Identifiers                 | Served Certificate Identifier |
+|-----------------------------------------------------|-----------------------------------------------------|-------------------------------|
+| `127.0.0.1,example.com`,`*.example.com,example.com` | `*.example.com,example.com`,`127.0.0.1,example.com` | `127.0.0.1,example.com`       |
+| `*.example.com,example.com`,`example.com`           | `*.example.com,example.com`,`example.com`           | `example.com`                 |
+
+### Caching TLS Certificates
+
+While Traefik is serving the best matching TLS certificate for each incoming connection,
+the selection process cost for each incoming connection is avoided thanks to a cache mechanism.
+
+Once a TLS certificate has been selected as the "best" TLS certificate for a server name,
+it is cached for an hour, avoiding the selection process for further connections.
+
+Nonetheless, when a new configuration is applied, the cache is reset.
+

 When using the file provider,
 one easy way to check if the dynamic configuration is well-formed is to validate it with the [JSON Schema of the dynamic configuration](https://json.schemastore.org/traefik-v2-file-provider.json).
+
+## Why does Let's Encrypt wildcard certificate renewal/generation with DNS challenge fail?
+
+If you're trying to renew wildcard certificates, with DNS challenge,
+and you're getting errors such as:
+
+```txt
+msg="Error renewing certificate from LE: {example.com [*.example.com]}"
+providerName=letsencrypt.acme error="error: one or more domains had a problem:

+then it could be due to `CNAME` support.
+
+In which case, you should make sure your infrastructure is properly set up for a
+`DNS` challenge that does not rely on `CNAME`, and you should try disabling `CNAME` support with:

+# 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.

+
+# 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`.
+

 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).

 If your backend is serving assets (e.g., images or JavaScript files), it can use the `X-Forwarded-Prefix` header to properly construct relative URLs.

+
+# 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.
+
+`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.
+
+## 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/).
+
+## 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.
+
+## Docker & Docker Swarm
+
+In v3, the provider Docker has been split into 2 providers:
+
+- Docker provider (without Swarm support)
+- Swarm provider  (Swarm support only)
+
+## 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.

+
+In `v2.10`, the `namespace` option of the Nomad provider is deprecated, please use the `namespaces` options instead.
+
+### Kubernetes CRDs
+
+In `v2.10`, the Kubernetes CRDs API Group `traefik.containo.us` is deprecated, and its support will end starting with Traefik v3. Please use the API Group `traefik.io` instead.
+
+As the Kubernetes CRD provider still works with both API Versions (`traefik.io/v1alpha1` and `traefik.containo.us/v1alpha1`),
+it means that for the same kind, namespace and name, the provider will only keep the `traefik.io/v1alpha1` resource.

+In addition, the Kubernetes CRDs API Version `traefik.io/v1alpha1` will not be supported in Traefik v3 itself.
+
+Please note that it is a requirement to update the CRDs and the RBAC in the cluster before upgrading Traefik.
+To do so, please apply the required [CRDs](https://raw.githubusercontent.com/traefik/traefik/v2.10/docs/content/reference/dynamic-configuration/kubernetes-crd-definition-v1.yml) and [RBAC](https://raw.githubusercontent.com/traefik/traefik/v2.10/docs/content/reference/dynamic-configuration/kubernetes-crd-rbac.yml) manifests for v2.10:

 ## 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)"

+### `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.

+
+And performing a request with a custom User-Agent:
+
+```bash
+curl -H "User-Agent: foobar" http://localhost
+```
+
+The following metric is produced :

+traefik_entrypoint_requests_total{code="200",entrypoint="web",method="GET",protocol="http",useragent="foobar"} 1

+    The `Host` header is never present in the Header map of a request, as per go documentation says:
+    // For incoming requests, the Host header is promoted to the
+    // Request.Host field and removed from the Header map.
+
+    As a workaround, to obtain the Host of a request as a label, one should use instead the `X-Forwarded-For` header.
