 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.

-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. 
+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, 
+so 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. 
+  
+If you have questions about the Triage process,
+[read more here](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md).  
+  
+## 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.
+* Pass the validation check.
+* Pass all tests.
+* Receive 3 approving reviews maintainers.
+
+## Pull Request Review Cycle
+
+You can read about our Triage Process [here](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md), 
+but 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?

+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 easy 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.
+

+
+## 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.

+
+# 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:v2.9
+          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)

+
+### `exposedByDefault`
+
+_Optional, Default=true_
+
+Expose Nomad services by default in Traefik.
+If set to `false`, services that do not have a `traefik.enable=true` tag will be ignored from the resulting routing configuration.
+
+For additional information, refer to [Restrict the Scope of Service Discovery](./overview.md#restrict-the-scope-of-service-discovery).
+
+```yaml tab="File (YAML)"
+providers:
+  nomad:

+# ...
+```
+
+### `defaultRule`
+
+_Optional, Default=```Host(`{{ normalize .Name }}`)```_
+
+The default host rule for all services.
+
+For a given service, if no routing rule was defined by a tag, it is defined by this `defaultRule` instead.
+The `defaultRule` must be set to a valid [Go template](https://pkg.go.dev/text/template/),
+and can include [sprig template functions](https://masterminds.github.io/sprig/).
+The service name can be accessed with the `Name` identifier,
+and the template has access to all the labels (i.e. tags beginning with the `prefix`) defined on this service.
+
+The option can be overridden on an instance basis with the `traefik.http.routers.{name-of-your-choice}.rule` tag.
+
+```yaml tab="File (YAML)"
+providers:
+  nomad:
+    defaultRule: "Host(`{{ .Name }}.{{ index .Labels \"customLabel\"}}`)"
+    # ...

+# ...
+```
+
+### `constraints`
+
+_Optional, Default=""_
+
+The `constraints` option can be set to an expression that Traefik matches against the service tags to determine whether
+to create any route for that service. If none of the service tags match the expression, no route for that service is
+created. If the expression is empty, all detected services are included.
+
+The expression syntax is based on the ```Tag(`tag`)```, and ```TagRegex(`tag`)``` functions,
+as well as the usual boolean logic, as shown in examples below.
+
+??? example "Constraints Expression Examples"
+
+    ```toml
+    # Includes only services having the tag `a.tag.name=foo`
+    constraints = "Tag(`a.tag.name=foo`)"
+    ```

+```yaml

+
+When ConsulCatalog, in the context of a Nomad orchestrator,
+is a provider (of service registration) for Traefik,
+one might have the need to distinguish within Traefik between a [Canary](https://learn.hashicorp.com/tutorials/nomad/job-blue-green-and-canary-deployments#deploy-with-canaries) instance of a service, or a production one.
+For example if one does not want them to be part of the same load-balancer.
+
+Therefore, this option, which is meant to be provided as one of the values of the `canary_tags` field in the Nomad [service stanza](https://www.nomadproject.io/docs/job-specification/service#canary_tags),
+allows Traefik to identify that the associated instance is a canary one.
+
 #### Port Lookup
 
 Traefik is capable of detecting the port to use, by following the default consul Catalog flow.
