+# Feature Deprecation Notices
+
+This page is maintained and updated periodically to reflect our roadmap and any decisions around feature deprecation.
+
+| Feature                                                       | Deprecated | End of Support | Removal |

+## Impact
+
+### Pilot Dashboard (Metrics)
+
+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.
+
+### Pilot Plugins 
+
+Starting on 2.7 the pilot token will not be a requirement anymore.  
+At 2.9, a new plugin catalog home should be available, decoupled from pilot.
+
+### Consul Enterprise Namespaces
+
+Starting on 2.8 the `namespace` option of Consul and Consul Catalog providers is deprecated, 
+please use the `namespaces` options instead.

+--providers.nomad.endpoint.tls.key=path/to/foo.key
+```
+
+##### `insecureSkipVerify`
+
+_Optional, Default=false_
+
+If `insecureSkipVerify` is `true`, the TLS connection to Nomad accepts any certificate presented by the server regardless of the hostnames it covers.
+
+```yaml tab="File (YAML)"
+providers:
+  nomad:
+    endpoint:
+      tls:
+        insecureSkipVerify: true
+```
+
+```toml tab="File (TOML)"
+[providers.nomad.endpoint.tls]
+  insecureSkipVerify = true
+```
+
+```bash tab="CLI"
+--providers.nomad.endpoint.tls.insecureskipverify=true
+```
+
+### `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:
+    exposedByDefault: false
+    # ...
+```
+
+```toml tab="File (TOML)"
+[providers.nomad]
+  exposedByDefault = false
+  # ...
+```
+
+```bash tab="CLI"
+--providers.nomad.exposedByDefault=false
+# ...
+```
+
+### `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\"}}`)"
+    # ...
+```
+
+```toml tab="File (TOML)"
+[providers.nomad]
+  defaultRule = "Host(`{{ .Name }}.{{ index .Labels \"customLabel\"}}`)"
+  # ...
+```
+
+```bash tab="CLI"
+--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`)"
+    ```
+
+    ```toml
+    # Excludes services having any tag `a.tag.name=foo`
+    constraints = "!Tag(`a.tag.name=foo`)"
+    ```
+
+    ```toml
+    # With logical AND.
+    constraints = "Tag(`a.tag.name`) && Tag(`another.tag.name`)"
+    ```
+
+    ```toml
+    # With logical OR.
+    constraints = "Tag(`a.tag.name`) || Tag(`another.tag.name`)"
+    ```
+
+    ```toml
+    # With logical AND and OR, with precedence set by parentheses.
+    constraints = "Tag(`a.tag.name`) && (Tag(`another.tag.name`) || Tag(`yet.another.tag.name`))"
+    ```
+
+    ```toml
+    # Includes only services having a tag matching the `a\.tag\.t.+` regular expression.
+    constraints = "TagRegex(`a\.tag\.t.+`)"
+    ```
+
+```yaml tab="File (YAML)"
+providers:
+  nomad:
+    constraints: "Tag(`a.tag.name`)"
+    # ...
+```
+
+```toml tab="File (TOML)"

+  # ...
+```

+# ...
+```
+
+For additional information, refer to [Restrict the Scope of Service Discovery](./overview.md#restrict-the-scope-of-service-discovery).
+
+### `namespace`
+
+_Optional, Default=""_
+
+The `namespace` option defines the namespace in which the Nomad services will be discovered.
+
+```yaml tab="File (YAML)"
+providers:
+  nomad:
+    namespace: "production"
+    # ...
+```

+# Traefik and Nomad Service Discovery
+
+A story of Tags, Services & Nomads
+{: .subtitle }
+
+![Nomad](../../assets/img/providers/nomad.png)
+
+Attach tags to your Nomad services and let Traefik do the rest!
+
+## Routing Configuration
+
+!!! info "tags"
+
+    - tags are case insensitive.
+    - The complete list of tags can be found [the reference page](../../reference/dynamic-configuration/nomad.md)
+
+### General
+
+Traefik creates, for each Nomad service, a corresponding Traefik [service](../services/index.md) and [router](../routers/index.md).
+
+The Traefik service automatically gets a server per instance in this Nomad service, and the router gets a default rule attached to it, based on the Nomad service name.
+
+### Routers
+
+To update the configuration of the Router automatically attached to the service, add tags starting with `traefik.routers.{name-of-your-choice}.` and followed by the option you want to change.
+
+For example, to change the rule, you could add the tag ```traefik.http.routers.my-service.rule=Host(`example.com`)```.
+
+??? info "`traefik.http.routers.<router_name>.rule`"
+
+    See [rule](../routers/index.md#rule) for more information.

+
+To update the configuration of the Service automatically attached to the service,
+add tags starting with `traefik.http.services.{name-of-your-choice}.`, followed by the option you want to change.
+

+### Middleware
+
+You can declare pieces of middleware using tags starting with `traefik.http.middlewares.{name-of-your-choice}.`, followed by the middleware type/options.
+
+For example, to declare a middleware [`redirectscheme`](../../middlewares/http/redirectscheme.md) named `my-redirect`, you'd write `traefik.http.middlewares.my-redirect.redirectscheme.scheme: https`.
+
+More information about available middlewares in the dedicated [middlewares section](../../middlewares/overview.md).
+
+??? example "Declaring and Referencing a Middleware"
+
+    ```yaml
+    # ...
+    # Declaring a middleware
+    traefik.http.middlewares.my-redirect.redirectscheme.scheme=https
+    # Referencing a middleware
+    traefik.http.routers.my-service.middlewares=my-redirect
+    ```
+
+!!! warning "Conflicts in Declaration"
+
+    If you declare multiple middleware with the same name but with different parameters, the middleware fails to be declared.
+
+### TCP
+
+You can declare TCP Routers and/or Services using tags.
+
+??? example "Declaring TCP Routers and Services"
+
+    ```yaml

+    ```
+
+!!! warning "TCP and HTTP"
+
+    If you declare a TCP Router/Service, it will prevent Traefik from automatically creating an HTTP Router/Service (like it does by default if no TCP Router/Service is defined).

+### Specific Provider Options
+
+#### `traefik.enable`
+
+```yaml
+traefik.enable=true
+```
+
+You can tell Traefik to consider (or not) the service by setting `traefik.enable` to true or false.
+
+This option overrides the value of `exposedByDefault`.
+
+#### Port Lookup
+
+Traefik is capable of detecting the port to use, by following the default Nomad Service Discovery flow.
+That means, if you just expose lets say port `:1337` on the Nomad job, traefik will pick up this port and use it.

+    However, HealthCheck does not need to be enabled on the failover service itself for it to be functional.
+    It is only required in order to propagate upwards the information when the failover itself becomes down
+    (i.e. both its main and its fallback are down too).

+# Traefik Hub (Experimental)
+
+## Overview
+
+Once the Traefik Hub Experimental feature is enabled in Traefik,
+Traefik and its local agent communicate together.
+
+This agent can:
+
+* get the Traefik metrics to display them in the Traefik Hub UI
+* secure the Traefik routers
+* provide ACME certificates to Traefik
+* transfer requests from the SaaS Platform to Traefik (and then avoid the users to expose directly their infrastructure on the internet)
+
+!!! warning "Traefik Hub Entrypoints"
+
+    When the Traefik Hub feature is enabled, Traefik exposes some services meant for the Traefik Hub Agent on dedicated entrypoints (on ports `9900` and `9901` by default).
+    Given their sensitive nature, those services should not be publicly exposed.
+    Also those dedicated entrypoints, regardless of how they are created (default, or user-defined), should not be used by anything other than the Hub Agent.
+
+!!! important "Learn More About Traefik Hub"
+
+    This section is intended only as a brief overview for Traefik users who are not familiar with Traefik Hub.
+    To explore all that Traefik Hub has to offer, please consult the [Traefik Hub Documentation](https://doc.traefik.io/traefik-hub).
+
+!!! Note "Prerequisites"
+
+    * Traefik Hub is compatible with Traefik Proxy 2.7 or later.
+    * The Traefik Hub Agent must be installed to connect to the Traefik Hub platform.
+    * Activate this feature in the experimental section of the static configuration.

+## Configuration
+
+### Entrypoints
+
+#### `traefikhub-api`
+
+This entrypoint is used to communicate between the Hub agent and Traefik. 
+It allows the Hub agent to create routing.
+
+This dedicated Traefik Hub entryPoint should not be used by anything other than Traefik Hub.
+
+The default port is `9900`.
+To change the port, you have to define an entrypoint named `traefikhub-api`.
+
+```yaml tab="File (YAML)"
+entryPoints:
+  traefikhub-api: ":8000"
+```
+
+```toml tab="File (TOML)"
+[entryPoints.traefikhub-api]
+  address = ":8000"
+```
+
+```bash tab="CLI"
+--entrypoints.traefikhub-api.address=:8000
+```
+
+#### `traefikhub-tunl`
+
+This entrypoint is used to communicate between Traefik Hub and Traefik.
+It allows to create secured tunnels.
+
+This dedicated Traefik Hub entryPoint should not be used by anything other than Traefik Hub.
+
+The default port is `9901`.
+To change the port, you have to define an entrypoint named `traefikhub-tunl`.
+
+```yaml tab="File (YAML)"
+entryPoints:
+  traefikhub-tunl: ":8000"
+```
+
+```toml tab="File (TOML)"
+[entryPoints.traefikhub-tunl]
+  address = ":8000"
+```
+
+```bash tab="CLI"
+--entrypoints.traefikhub-tunl.address=:8000
+```
+
+### `tls`
+
+_Optional, Default=None_
+
+This section is required when using the Hub agent for Docker.
+
+This section allows configuring mutual TLS connection between Traefik Proxy and the Traefik Hub Agent.
+The key and the certificate are the credentials for Traefik Proxy as a TLS client.
+The certificate authority authenticates the Traefik Hub Agent certificate.
+
+!!! note "Certificate Domain"
+
+    The certificate must be valid for the `proxy.traefik` domain.
+
+!!! note "Certificates Definition"
+
+    Certificates can be defined either by their content or their path.
+
+!!! note "Insecure Mode"
+
+    The `insecure` option is mutually exclusive with any other option.
