 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.

+Do your best to explain what you're looking for, and why it would improve Traefik for everyone.
+Be detailed and share the use-case(s) to allow us to see the value of your feature request as quickly as possible.
+
+Features with a lot of positive interaction (claps, +1s, conversation about how this would impact them) indicate higher community interest and help us to prioritize.
+
+If you are interested in creating a PR for your feature request, let us know in the issue, so we can work with you.
+It can take a lot of work to make sure a PR can integrate with our existing code and planning with the team ahead of time can make sure that your PR can be accepted and merged quickly.
+
+## Issues or Possible Bug Reports
+
+Follow the [issue template](https://github.com/traefik/traefik/blob/master/.github/ISSUE_TEMPLATE/bug_report.yml) as much as possible.

-A Quick Guide for Efficient Contributions
-{: .subtitle }
+# Before You Submit a Pull Request
 
-So you've decided to improve Traefik? 
-Thank You! 
+This guide is for contributors who already have a pull request to submit.
+If you are looking for information on setting up your developer environment
+and creating code to contribute to Traefik Proxy or related projects,
+see the [development guide](https://docs.traefik.io/contributing/building-testing/).
 
-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).
+Looking for a way to contribute to Traefik Proxy?
+Check out this list of [Priority Issues](https://github.com/traefik/traefik/labels/contributor%2Fwanted),
+the [Good First Issue](https://github.com/traefik/traefik/labels/contributor%2Fgood-first-issue) list,
+or the list of [confirmed bugs](https://github.com/traefik/traefik/labels/kind%2Fbug%2Fconfirmed) waiting to be remedied.
+
+## How We Prioritize
+
+We wish we could review every pull request right away.
+Unfortunately, our team has to prioritize pull requests (PRs) for review
+(but we are welcoming new [maintainers](https://github.com/traefik/traefik/blob/master/docs/content/contributing/maintainers-guidelines.md) to speed this up,
+if you are interested, check it out and apply).
+
+The PRs we are able to handle 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 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.
+* Ping `@tfny` if you have not been assigned to a reviewer.
+
+For more information on best practices, try these links:

+
+## 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.

+## 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 CRDs API Group `traefik.containo.us`
+
+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.
+
+### Kubernetes CRDs API Version `traefik.io/v1alpha1`
+
+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`.

 # 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, Middelwares 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) ...).

+The "field not found" error occurs, when an unknown property is encountered in the dynamic or static configuration.

+One easy way to check whether a configuration file is well-formed, is to validate it with:

+
+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 obviously confirms that something went wrong while creating the resource,

+# Quick Start
+
+A Simple 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.
+
+In order 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 # Using "default" because we did not specify a namespace when creating the ClusterAccount.
+```
+
+!!! 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:v2.10
+          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 a simple 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)

+For authentication policies that require verification of the client certificate, the certificate authority for the certificates should be set in `clientAuth.caFiles`.

+In Kubernetes environment, CA certificate can be set in `clientAuth.secretNames`. See [TLSOption resource](../../routing/providers/kubernetes-crd#kind-tlsoption) for more details.
 
 The `clientAuth.clientAuthType` option governs the behaviour as follows:
 
 - `NoClientCert`: disregards any client certificate.
 - `RequestClientCert`: asks for a certificate but proceeds anyway if none is provided.
-- `RequireAnyClientCert`: requires a certificate but does not verify if it is signed by a CA listed in `clientAuth.caFiles`.
-- `VerifyClientCertIfGiven`: if a certificate is provided, verifies if it is signed by a CA listed in `clientAuth.caFiles`. Otherwise proceeds without any certificate.

 ### CORS Headers
 
 CORS (Cross-Origin Resource Sharing) headers can be added and configured in a manner similar to the custom headers above.
 This functionality allows for more advanced security features to quickly be set.
+If CORS headers are set, then the middleware does not pass preflight requests to any service,
+instead the response will be generated and sent back to the client directly.  
+Please note that the example below is by no means authoritative or exhaustive,

+!!! warning "When behind another reverse-proxy"
+
+    When there is at least one other reverse-proxy between the client and Traefik, 
+    the other reverse-proxy (i.e. the last hop) needs to be a [trusted](../../routing/entrypoints.md#forwarded-headers) one.

+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:

+Defines the extra labels for the `requests_total` metrics, and for each of them, the request header containing the value for this label.
+Please note that if the header is not present in the request it will be added nonetheless with an empty value.
+In addition, the label should be a valid label name for Prometheus metrics,

+
+When configuring the label in Static Configuration:
+
+```yaml tab="File (YAML)"
+metrics:
+  prometheus:
+    headerLabels:

+```
+
+```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
