 Traefik (pronounced _traffic_) is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy.
 Traefik integrates with your existing infrastructure components ([Docker](https://www.docker.com/), [Swarm mode](https://docs.docker.com/engine/swarm/), [Kubernetes](https://kubernetes.io), [Marathon](https://mesosphere.github.io/marathon/), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Rancher](https://rancher.com), [Amazon ECS](https://aws.amazon.com/ecs), ...) and configures itself automatically and dynamically.

+You want to build your own Traefik binary from the sources?
 Let's see how.
 
 ## Building
 
-You need either [Docker](https://github.com/docker/docker) and `make` (Method 1), or `go` (Method 2) in order to build Traefik.
-For changes to its dependencies, the `dep` dependency management tool is required.
-
-### Method 1: Using `Docker` and `Makefile`
-
-Run make with the `binary` target.
-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.
-
-```bash
-$ make binary

-
-- `test-unit`
-- `test-integration`
-- `validate`
-- `binary` (the webUI is still generated by using Docker)
-
-ex:
-
-```bash
-IN_DOCKER= make test-unit
-```

-
 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).
+- [PR review](https://github.com/traefik/contributors-guide/blob/master/pr_guidelines.md).
 
-## Governance
+- [Design review](https://github.com/traefik/contributors-guide/blob/master/proposals.md).
 
-- 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. 
-  You can reach Traefik core developers directly,
-  which offers the possibility to discuss issues, pull requests, enhancements more efficiently
+- All of our maintainers are added to the Traefik Maintainers Discord server that belongs to Traefik labs.
+  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.

-Please review the [guidelines on creating PRs](https://github.com/traefik/contributors-guide/blob/master/pr_guidelines.md) for Traefik in our [contributors guide repository](https://github.com/traefik/contributors-guide).
+## How We Prioritize
+
+We wish we could review every pull request right away, but because it's a time consuming operation, it's not always possible.
+
+The PRs we are able to handle the fastest are:
+
+* Documentation updates.
+* Bug fixes.
+* Enhancements and Features with a `contributor/wanted` tag.
+
+PRs that take more time to address include:
+
+* Enhancements or Features without the `contributor/wanted` tag.
+
+If you have an idea for an enhancement or feature that you would like to build,
+[create an issue](https://github.com/traefik/traefik/issues/new/choose) for it first
+and tell us you are interested in writing the PR.
+If an issue already exists, definitely comment on it to tell us you are interested in creating a PR.
+
+This will allow us to communicate directly and let you know if it is something we would accept.
+
+It also allows us to make sure you have all the information you need during the design phase
+so that it can be reviewed and merged quickly.
+
+Read more about the [Triage process](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md) in the docs.
+
+## The Pull Request Submit Process
+
+Merging a PR requires the following steps to be completed before it is merged automatically.
+
+* Make sure your pull request adheres to our best practices. These include:
+    * [Following project conventions](https://github.com/traefik/traefik/blob/master/docs/content/contributing/maintainers-guidelines.md); including using the PR Template.
+    * Make small pull requests.
+    * Solve only one problem at a time.
+    * Comment thoroughly.
+    * Do not open the PR from an organization repository.
+    * Keep "allows edit from maintainer" checked.
+    * Use semantic line breaks for documentation.
+    * Ensure your PR is not a draft. We do not review drafts, but do answer questions and confer with developers on them as needed.
+* Pass the validation check.
+* Pass all tests.
+* Receive 3 approving reviews from maintainers.
+
+## Pull Request Review Cycle
+
+Learn about our [Triage Process](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md),
+in short, it looks like this:
+
+* We triage every new PR or comment before entering it into the review process.
+    * We ensure that all prerequisites for review have been met.
+    * We check to make sure the use case meets our needs.
+    * We assign reviewers.
+* Design Review.
+    * This takes longer than other parts of the process.
+    * We review that there are no obvious conflicts with our codebase.
+* Code Review.
+    * We review the code in-depth and run tests.
+    * We may ask for changes here.
+    * During code review, we ask that you be reasonably responsive,
+      if a PR languishes in code review it is at risk of rejection,
+      or we may take ownership of the PR and the contributor will become a co-author.
+* Merge.
+    * Success!
+
+!!! note
+
+    Occasionally, we may freeze our codebase when working towards a specific feature or goal that could impact other development.
+    During this time, your pull request could remain unmerged while the release work is completed.
+
+## Run Local Verifications
+
+You must run these local verifications before you submit your pull request to predict the pass or failure of continuous integration.
+Your PR will not be reviewed until these are green on the CI.
+
+* `make validate`
+* `make pull-images`
+* `make test`
+
+## The Testing and Merge Workflow
+
+Pull Requests are managed by the bot [Myrmica Lobicornis](https://github.com/traefik/lobicornis).
+This bot is responsible for verifying GitHub Checks (CI, Tests, etc), mergability, and minimum reviews.
+In addition, it rebases or merges with the base PR branch if needed.
+It performs several other housekeeping items
+and you can read more about those on the [README](https://github.com/traefik/lobicornis) for Lobicornis.
+
+The maintainer giving the final LGTM must add the `status/3-needs-merge` label to trigger the merge bot.
+
+By default, a squash-rebase merge will be carried out.
+
+The status `status/4-merge-in-progress` is only used by the bot.
+
+If the bot is not able to perform the merge, the label `bot/need-human-merge` is added.
+In such a situation, solve the conflicts/CI/... and then remove the label `bot/need-human-merge`.
+
+To prevent the bot from automatically merging a PR, add the label `bot/no-merge`.
+
+The label `bot/light-review` decreases the number of required LGTM from 3 to 1.
+
+This label can be used when:
+
+* Updating a dependency.
+* Merging branches back into the next version branch.
+* Submitting minor documentation changes.
+* Submitting changelog PRs.
+
+## Why Was My Pull Request Closed?
+
+Traefik Proxy is made by the community for the community,
+as such the goal is to engage the community to make Traefik the best reverse proxy available.
+Part of this goal is maintaining a lean codebase and ensuring code velocity.
+unfortunately, this means that sometimes we will not be able to merge a pull request.
+
+Because we respect the work you did, you will always be told why we are closing your pull request.
+If you do not agree with our decision, do not worry; closed pull requests are effortless to recreate,
+and little work is lost by closing a pull request that subsequently needs to be reopened.
+
+Your pull request might be closed if:
+
+* Your PR's design conflicts with our existing codebase in such a way that merging is not an option
+  and the work needed to make your pull request usable is too high.
+    * To prevent this, make sure you created an issue first
+      and think about including Traefik Proxy maintainers in your design phase to minimize conflicts.
+* Your PR is for an enhancement or feature that we will not use.
+    * Please remember to create an issue for any pull request **before** you create a PR
+      to ensure that your goal is something we can merge and that you have any design insight you might need from the team.
+* Your PR has been waiting for feedback from the contributor for over 90 days.
+
+## Why is My Pull Request Not Getting Reviewed
+
+A few factors affect how long your pull request might wait for review.
+
+We must prioritize which PRs we focus on.
+Our first priority is PRs we have identified as having high community engagement and broad applicability.
+We put our top priorities on our roadmap, and you can identify them by the `contributor/wanted` tag.
+These PRs will enter our review process the fastest.
+
+Our second priority is bug fixes.
+Especially for bugs that have already been tagged with `bug/confirmed`.
+These reviews enter the process quickly.
+
+If your PR does not meet the criteria above,
+it will take longer for us to review, as any PRs that do meet the criteria above will be prioritized.
+
+Additionally, during the last few weeks of a milestone, we stop reviewing PRs to reduce churn and stabilize.
+We will resume after the release.
+
+The second major reason that we deprioritize your PR is that you are not following best practices.
+
+The most common failures to follow best practices are:
+
+* You did not create an issue for the PR you wish to make.
+  If you do not create an issue before submitting your PR,
+  we will not be able to answer any design questions and let you know how likely your PR is to be merged.
+* You created pull requests that are too large to review.
+    * Break your pull requests up.
+      If you can extract whole ideas from your pull request and send those as pull requests of their own,
+      you should do that instead.
+      It is better to have many pull requests addressing one thing than one pull request addressing many things.
+    * Traefik Proxy is a fast-moving codebase — lock in your changes ASAP with your small pull request,
+      and make merges be someone else's problem.
+      We want every pull request to be useful on its own,
+      so use your best judgment on what should be a pull request vs. a commit.
+* You did not comment well.
+    * Comment everything.
+
+Please remember that we are working internationally, cross-culturally, and with different use-cases.
+Your reviewer will not intuitively understand the problem the same way you do or solve it the same way you would.
+This is why every change you make must be explained, and your strategy for coding must also be explained.
+
+* Your tests were inadequate or absent.
+    * If you do not know how to test your PR, please ask!
+      We will be happy to help you or suggest appropriate test cases.
+
+If you have already followed the best practices and your PR still has not received a response,
+here are some things you can do to move the process along:
+
+* If you have fixed all the issues from a review,
+  remember to re-request a review (using the designated button) to let your reviewer know that you are ready.
+  You can choose to comment with the changes you made.
+* Kindly comment on the pull request. Doing so will automatically give your PR visibility during the triage process.
+

+
+## It's OK to Push Back
+
+Sometimes reviewers make mistakes.
+It is OK to push back on changes your reviewer requested.
+If you have a good reason for doing something a certain way, you are absolutely allowed to debate the merits of a requested change.
+Both the reviewer and reviewee should strive to discuss these issues in a polite and respectful manner.
+
+You might be overruled, but you might also prevail.
+We are pretty reasonable people.
+
+Another phenomenon of open-source projects (where anyone can comment on any issue) is the dog-pile -
+your pull request gets so many comments from so many people it becomes hard to follow.
+In this situation, you can ask the primary reviewer (assignee) whether they want you to fork a new pull request
+to clear out all the comments.
+You do not have to fix every issue raised by every person who feels like commenting,
+but you should answer reasonable comments with an explanation.
+
+## Common Sense and Courtesy
+
+No document can take the place of common sense and good taste.
+Use your best judgment, while you put a bit of thought into how your work can be made easier to review.
+If you do these things, your pull requests will get merged with less friction.

 # 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.
+
+## What does the "field not found" error mean?
+
+```shell
+error: field not found, node: -badField-
+```
+
+The "field not found" error occurs, when an unknown property is encountered in the dynamic or static configuration.
+
+One way to check whether a configuration file is well-formed, is to validate it with:
+
+- [JSON Schema of the static configuration](https://json.schemastore.org/traefik-v2.json)
+- [JSON Schema of the dynamic configuration](https://json.schemastore.org/traefik-v2-file-provider.json)
+
+## Why are some resources (routers, middlewares, services...) not created/applied?
+
+As a common tip, if a resource is dropped/not created by Traefik after the dynamic configuration was evaluated,
+one should look for an error in the logs.
+
+If found, the error confirms that something went wrong while creating the resource,
+and the message should help in figuring out the mistake(s) in the configuration, and how to fix it.
+
+When using the file provider,
+one 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:
+[example.com] acme: error presenting token: gandiv5: unexpected authZone example.com. for fqdn example.com."
+```
+
+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:
+
+```shell
+LEGO_DISABLE_CNAME_SUPPORT=true
+```

+
+# Quick Start
+
+A Use Case of Traefik Proxy and Kubernetes
+{: .subtitle }
+
+This guide is an introduction to using Traefik Proxy in a Kubernetes environment.  
+The objective is to learn how to run an application behind a Traefik reverse proxy in Kubernetes.  
+It presents and explains the basic blocks required to start with Traefik such as Ingress Controller, Ingresses, Deployments, static, and dynamic configuration.
+
+## Permissions and Accesses
+
+Traefik uses the Kubernetes API to discover running services.
+
+To use the Kubernetes API, Traefik needs some permissions.
+This [permission mechanism](https://kubernetes.io/docs/reference/access-authn-authz/rbac/) is based on roles defined by the cluster administrator.  
+The role is then bound to an account used by an application, in this case, Traefik Proxy.
+
+The first step is to create the role.
+The [`ClusterRole`](https://kubernetes.io/docs/reference/kubernetes-api/authorization-resources/cluster-role-v1/#ClusterRole) resource enumerates the resources and actions available for the role.
+In a file called `00-role.yml`, put the following `ClusterRole`:
+
+```yaml tab="00-role.yml"
+kind: ClusterRole
+apiVersion: rbac.authorization.k8s.io/v1
+metadata:
+  name: traefik-role
+
+rules:
+  - apiGroups:
+      - ""
+    resources:
+      - services
+      - endpoints
+      - secrets
+    verbs:
+      - get
+      - list
+      - watch
+  - apiGroups:
+      - extensions
+      - networking.k8s.io
+    resources:
+      - ingresses
+      - ingressclasses
+    verbs:
+      - get
+      - list
+      - watch
+  - apiGroups:
+      - extensions
+      - networking.k8s.io
+    resources:
+      - ingresses/status
+    verbs:
+      - update
+```
+
+!!! info "You can find the reference for this file [there](../../reference/dynamic-configuration/kubernetes-crd/#rbac)."
+
+The next step is to create a dedicated service account for Traefik.
+In a file called `00-account.yml`, put the following [`ServiceAccount`](https://kubernetes.io/docs/reference/kubernetes-api/authentication-resources/service-account-v1/#ServiceAccount) resource:
+
+```yaml tab="00-account.yml"
+apiVersion: v1
+kind: ServiceAccount
+metadata:
+  name: traefik-account
+```
+
+And then, bind the role on the account to apply the permissions and rules on the latter. In a file called `01-role-binding.yml`, put the
+following [`ClusterRoleBinding`](https://kubernetes.io/docs/reference/kubernetes-api/authorization-resources/cluster-role-binding-v1/#ClusterRoleBinding) resource:
+
+```yaml tab="01-role-binding.yml"
+kind: ClusterRoleBinding
+apiVersion: rbac.authorization.k8s.io/v1
+metadata:
+  name: traefik-role-binding
+
+roleRef:
+  apiGroup: rbac.authorization.k8s.io
+  kind: ClusterRole
+  name: traefik-role
+subjects:
+  - kind: ServiceAccount
+    name: traefik-account
+    namespace: default # This tutorial uses the "default" K8s namespace.
+```
+
+!!! info "`roleRef` is the Kubernetes reference to the role created in `00-role.yml`."
+
+!!! info "`subjects` is the list of accounts reference."
+
+    In this guide, it only contains the account created in `00-account.yml`
+
+## Deployment and Exposition
+
+!!! info "This section can be managed with the help of the [Traefik Helm chart](../install-traefik/#use-the-helm-chart)."
+
+The [ingress controller](https://traefik.io/glossary/kubernetes-ingress-and-ingress-controller-101/#what-is-a-kubernetes-ingress-controller)
+is a software that runs in the same way as any other application on a cluster.  
+To start Traefik on the Kubernetes cluster,
+a [`Deployment`](https://kubernetes.io/docs/reference/kubernetes-api/workload-resources/deployment-v1/) resource must exist to describe how to configure
+and scale containers horizontally to support larger workloads.
+
+Start by creating a file called `02-traefik.yml` and paste the following `Deployment` resource:
+
+```yaml tab="02-traefik.yml"
+kind: Deployment
+apiVersion: apps/v1
+metadata:
+  name: traefik-deployment
+  labels:
+    app: traefik
+
+spec:
+  replicas: 1
+  selector:
+    matchLabels:
+      app: traefik
+  template:
+    metadata:
+      labels:
+        app: traefik
+    spec:
+      serviceAccountName: traefik-account
+      containers:
+        - name: traefik
+          image: traefik:v2.11
+          args:
+            - --api.insecure
+            - --providers.kubernetesingress
+          ports:
+            - name: web
+              containerPort: 80
+            - name: dashboard
+              containerPort: 8080
+```
+
+The deployment contains an important attribute for customizing Traefik: `args`.  
+These arguments are the static configuration for Traefik.  
+From here, it is possible to enable the dashboard,
+configure entry points,
+select dynamic configuration providers,
+and [more](../reference/static-configuration/cli.md).
+
+In this deployment,
+the static configuration enables the Traefik dashboard,
+and uses Kubernetes native Ingress resources as router definitions to route incoming requests.
+
+!!! info "When there is no entry point in the static configuration"
+
+    Traefik creates a default one called `web` using the port `80` routing HTTP requests.
+
+!!! info "When enabling the [`api.insecure`](../../operations/api/#insecure) mode, Traefik exposes the dashboard on the port `8080`."
+
+A deployment manages scaling and then can create lots of containers, called [Pods](https://kubernetes.io/docs/concepts/workloads/pods/).
+Each Pod is configured following the `spec` field in the deployment.  
+Given that, a Deployment can run multiple Traefik Proxy Pods,
+a piece is required to forward the traffic to any of the instance:
+namely a [`Service`](https://kubernetes.io/docs/reference/kubernetes-api/service-resources/service-v1/#Service).  
+Create a file called `02-traefik-services.yml` and insert the two `Service` resources:
+
+```yaml tab="02-traefik-services.yml"
+apiVersion: v1
+kind: Service
+metadata:
+  name: traefik-dashboard-service
+
+spec:
+  type: LoadBalancer
+  ports:
+    - port: 8080
+      targetPort: dashboard
+  selector:
+    app: traefik
+---
+apiVersion: v1
+kind: Service
+metadata:
+  name: traefik-web-service
+
+spec:
+  type: LoadBalancer
+  ports:
+    - targetPort: web
+      port: 80
+  selector:
+    app: traefik
+```
+
+!!! warning "It is possible to expose a service in different ways."
+
+    Depending on your working environment and use case, the `spec.type` might change.  
+    It is strongly recommended to understand the available [service types](https://kubernetes.io/docs/concepts/services-networking/service/#publishing-services-service-types) before proceeding to the next step.
+
+It is now time to apply those files on your cluster to start Traefik.
+
+```shell
+kubectl apply -f 00-role.yml \
+              -f 00-account.yml \
+              -f 01-role-binding.yml \
+              -f 02-traefik.yml \
+              -f 02-traefik-services.yml
+```
+
+## Proxying applications
+
+The only part still missing is the business application behind the reverse proxy.  
+For this guide, we use the example application [traefik/whoami](https://github.com/traefik/whoami),
+but the principles are applicable to any other application.
+
+The `whoami` application is an HTTP server running on port 80 which answers host-related information to the incoming requests.  
+As usual, start by creating a file called `03-whoami.yml` and paste the following `Deployment` resource:
+
+```yaml tab="03-whoami.yml"
+kind: Deployment
+apiVersion: apps/v1
+metadata:
+  name: whoami
+  labels:
+    app: whoami
+
+spec:
+  replicas: 1
+  selector:
+    matchLabels:
+      app: whoami
+  template:
+    metadata:
+      labels:
+        app: whoami
+    spec:
+      containers:
+        - name: whoami
+          image: traefik/whoami
+          ports:
+            - name: web
+              containerPort: 80
+```
+
+And continue by creating the following `Service` resource in a file called `03-whoami-services.yml`:
+
+```yaml tab="03-whoami-services.yml"
+apiVersion: v1
+kind: Service
+metadata:
+  name: whoami
+
+spec:
+  ports:
+    - name: web
+      port: 80
+      targetPort: web
+      
+  selector:
+    app: whoami
+```
+
+Thanks to the Kubernetes API,
+Traefik is notified when an Ingress resource is created, updated, or deleted.  
+This makes the process dynamic.  
+The ingresses are, in a way, the [dynamic configuration](../../providers/kubernetes-ingress/) for Traefik.
+
+!!! tip
+
+    Find more information on [ingress controller](https://kubernetes.io/docs/concepts/services-networking/ingress-controllers/),
+    and [Ingress](https://kubernetes.io/docs/concepts/services-networking/ingress/) in the official Kubernetes documentation.
+
+Create a file called `04-whoami-ingress.yml` and insert the `Ingress` resource:
+
+```yaml tab="04-whoami-ingress.yml"
+apiVersion: networking.k8s.io/v1
+kind: Ingress
+metadata:
+  name: whoami-ingress
+spec:
+  rules:
+  - http:
+      paths:
+      - path: /
+        pathType: Prefix
+        backend:
+          service:
+            name: whoami
+            port:
+              name: web
+```
+
+This `Ingress` configures Traefik to redirect any incoming requests starting with `/` to the `whoami:80` service.
+
+At this point, all the configurations are ready.
+It is time to apply those new files:
+
+```shell
+kubectl apply -f 03-whoami.yml \
+              -f 03-whoami-services.yml \
+              -f 04-whoami-ingress.yml
+```
+
+Now you should be able to access the `whoami` application and the Traefik dashboard.
+Load the dashboard on a web browser: [`http://localhost:8080`](http://localhost:8080).
+
+And now access the `whoami` application:
+
+```shell
+curl -v http://localhost/
+```
+
+!!! question "Going further"
+
+    - [Filter the ingresses](../providers/kubernetes-ingress.md#ingressclass) to use with [IngressClass](https://kubernetes.io/docs/concepts/services-networking/ingress/#ingress-class)
+    - Use [IngressRoute CRD](../providers/kubernetes-crd.md)
+    - Protect [ingresses with TLS](../routing/providers/kubernetes-ingress.md#enabling-tls-via-annotations)

+The `sourceRange` option sets the allowed IPs (or ranges of allowed IPs by using CIDR notation).
+
+### `ipStrategy`
+
+The `ipStrategy` option defines two parameters that set how Traefik determines the client IP: `depth`, and `excludedIPs`.  
+If no strategy is set, the default behavior is to match `sourceRange` against the Remote address found in the request.
+
+!!! important "As a middleware, whitelisting happens before the actual proxying to the backend takes place.

+#### `ipStrategy.depth`
+
+The `depth` option tells Traefik to use the `X-Forwarded-For` header and take the IP located at the `depth` position (starting from the right).
+
+- If `depth` is greater than the total number of IPs in `X-Forwarded-For`, then the client IP will be empty.
+- `depth` is ignored if its value is less than or equal to 0.
+
+!!! example "Examples of Depth & X-Forwarded-For"
+
+    If `depth` is set to 2, and the request `X-Forwarded-For` header is `"10.0.0.1,11.0.0.1,12.0.0.1,13.0.0.1"` then the "real" client IP is `"10.0.0.1"` (at depth 4) but the IP used is `"12.0.0.1"` (`depth=2`).

 During the transition from v1 to v2, a number of internal pieces and components of Traefik were rewritten and reorganized.
 As such, the combination of core notions such as frontends and backends has been replaced with the combination of [routers](../routing/routers/index.md), [services](../routing/services/index.md), and [middlewares](../middlewares/overview.md).

 In `v2.6.1`, the Datadog tags added to a span changed from `service.name` to `traefik.service.name` and from `router.name` to `traefik.router.name`.
+
+## v2.8
+
+### TLS client authentication
+
+In `v2.8`, the `caOptional` option is deprecated as TLS client authentication is a server side option.
+This option available in the ForwardAuth middleware, as well as in the HTTP, Consul, Etcd, Redis, ZooKeeper, Marathon, Consul Catalog, and Docker providers has no effect and must not be used anymore.
+
+### Consul Enterprise Namespaces

+In `v2.8`, the `namespace` option of Consul and Consul Catalog providers is deprecated, please use the `namespaces` options instead.

+### Traefik Pilot

+In `v2.8`, the `pilot.token` and `pilot.dashboard` options are deprecated.

+### Nomad Namespace
+
+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:

+
+When configuring the label in Static Configuration:
+
+```yaml tab="File (YAML)"
+metrics:
+  prometheus:
+    headerLabels:
+      useragent: User-Agent
+```
+
+```toml tab="File (TOML)"

+      useragent = "User-Agent"
+```
+
+```bash tab="CLI"
+--metrics.prometheus.headerlabels.useragent=User-Agent
+```
+
+And performing a request with a custom User-Agent:
+
+```bash
+curl -H "User-Agent: foobar" http://localhost
+```
+
+The following metric is produced :
+
+```bash
+traefik_entrypoint_requests_total{code="200",entrypoint="web",method="GET",protocol="http",useragent="foobar"} 1
+```
+
+!!! info "`Host` header value"
+
+    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.
