+### Verify Documentation
+
+You can verify that the documentation meets some expectations, as checking for dead links, html markup validity.
+
+```bash
+$ make docs-verify
+docker build -t traefik-docs-verify ./script/docs-verify-docker-image ## Build Validator image
+...
+docker run --rm -v /home/travis/build/containous/traefik:/app traefik-docs-verify ## Check for dead links and w3c compliance
+=== Checking HTML content...
+Running ["HtmlCheck", "ImageCheck", "ScriptCheck", "LinkCheck"] on /app/site/basics/index.html on *.html...
+```
+
+If you recently changed the documentation, do not forget to clean it to have it rebuilt:
+
+```bash
+$ make docs-clean docs-verify
+...
+```

+A health check can be configured in order to remove a backend from LB rotation as long as it keeps returning HTTP status codes other than `2xx` or `3xx` to HTTP GET requests periodically carried out by Traefik.  
 The check is defined by a path appended to the backend URL and an interval (given in a format understood by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration)) specifying how often the health check should be executed (the default being 30 seconds).
 Each backend must respond to the health check within 5 seconds.  
 By default, the port of the backend server is used, however, this may be overridden.

+### Multiple frontends for a single service
+
+If you need to support multiple frontends for a service, for example when having multiple `rules` that can't be combined, specify them as follows:
+
+```
+<prefix>.frontends.A.rule=Host:A:PathPrefix:/A
+<prefix>.frontends.B.rule=Host:B:PathPrefix:/
+```
+
+`A` and `B` here are just arbitrary names, they can be anything. You can use any setting that applies to `<prefix>.frontend` from the table above.

 [1] `traefik.docker.network`:
 If a container is linked to several networks, be sure to set the proper network name (you can check with `docker inspect <container_id>`) otherwise it will randomly pick one (depending on how docker is returning them).
 For instance when deploying docker `stack` from compose files, the compose defined networks will be prefixed with the `stack` name.
 Or if your service references external network use it's name instead.

 ### TLS communication between Traefik and backend pods
 
 Traefik automatically requests endpoint information based on the service provided in the ingress spec.
 Although traefik will connect directly to the endpoints (pods), it still checks the service port to see if TLS communication is required.
-If the service port defined in the ingress spec is 443, then the backend communication protocol is assumed to be TLS, and will connect via TLS automatically.
+
+There are 2 ways to configure Traefik to use https to communicate with backend pods:
+
+1. If the service port defined in the ingress spec is 443 (note that you can still use `targetPort` to use a different port on your pod).
+2. If the service port defined in the ingress spec has a name that starts with `https` (such as `https-api`, `https-web` or just `https`).
+
+If either of those configuration options exist, then the backend communication protocol is assumed to be TLS, and will connect via TLS automatically.
 
 !!! note
     Please note that by enabling TLS communication between traefik and your pods, you will have to have trusted certificates that have the proper trust chain and IP subject name.

+Service weights enable to split traffic across multiple backing services in a fine-grained manner.
+
+Example:

+```yaml

+service_backend2: 12.50%
+service_backend3: 75 # Same as 75%, the percentage sign is optional
+```
+
+A single service backend definition may be omitted; in this case, Traefik auto-completes that service backend to 100% automatically.
+Conveniently, users need not bother to compute the percentage remainder for a main service backend.
+For instance, in the example above `service_backend3` does not need to be specified to be assigned 75%.
+
+!!! note
+    For each service weight given, the Ingress specification must include a backend item with the corresponding `serviceName` and (if given) matching path.
+
+Currently, 3 decimal places for the weight are supported.
+An attempt to exceed the precision should be avoided as it may lead to percentage computation flaws and, in consequence, Ingress parsing errors.
+
+For each path definition, this annotation will fail if:
+
+- the sum of backend weights exceeds 100% or
+- the sum of backend weights is less than 100% without one or more omitted backends

+This ingress follows the [Global Default Backend](https://kubernetes.io/docs/concepts/services-networking/ingress/#the-ingress-resource) property of ingresses.
+This will allow users to create a "default backend" that will match all unmatched requests.
+
+!!! note
+    Due to Træfik's use of priorities, you may have to set this ingress priority lower than other ingresses in your environment, to avoid this global ingress from satisfying requests that _could_ match other ingresses.
+    To do this, use the `traefik.ingress.kubernetes.io/priority` annotation (as seen in [General Annotations](/configuration/backends/kubernetes/#general-annotations)) on your ingresses accordingly.

+### Applications with Multiple Ports (segment labels)
+
+Segment labels are used to define routes to an application exposing multiple ports.
+A segment is a group of labels that apply to a port exposed by an application.
+You can define as many segments as ports exposed in an application.
+
+Additionally, if a segment name matches a named port, that port will be used unless `portIndex`, `portName`, or `port` labels are specified for that segment.
+
+Segment labels override the default behavior.
+

@@ -874,6 +876,89 @@ For such cases, it is advisable to classify Ingress objects through a label and
 To stick with the internal/external example above, all Ingress objects meant for internal traffic could receive a `traffic-type: internal` label while objects designated for external traffic receive a `traffic-type: external` label.
 The label selectors on the Træfik Deployments would then be `traffic-type=internal` and `traffic-type=external`, respectively.
 
+## Traffic Splitting
+
+It is possible to split Ingress traffic in a fine-grained manner between multiple deployments using _service weights_.
+
+One canonical use case is canary releases where a deployment representing a newer release is to receive an initially small but ever-increasing fraction of the requests over time.
+The way this can be done in Træfik is to specify a percentage of requests that should go into each deployment.
+
+For instance, say that an application `my-app` runs in version 1.
+A newer version 2 is about to be released, but confidence in the robustness and reliability of new version running in production can only be gained gradually.
+Thus, a new deployment `my-app-canary` is created and scaled to a replica count that suffices for a 1% traffic share.
+Along with it, a Service object is created as usual.
+
+The Ingress specification would look like this:
+
+```yaml
+apiVersion: extensions/v1beta1
+kind: Ingress
+metadata:
+  annotations:
+    traefik.ingress.kubernetes.io/service-weights: |
+      my-app: 99%
+      my-app-canary: 1%
+  name: my-app
+spec:
+  rules:
+  - http:
+      paths:
+      - backend:
+          serviceName: my-app
+          servicePort: 80
+        path: /
+      - backend:
+          serviceName: my-app-canary
+          servicePort: 80
+        path: /
+```
+
+Take note of the `traefik.ingress.kubernetes.io/service-weights` annotation: It specifies the distribution of requests among the referenced backend services, `my-app` and `my-app-canary`.
+With this definition, Træfik will route 99% of the requests to the pods backed by the `my-app` deployment, and 1% to those backed by `my-app-canary`.
+Over time, the ratio may slowly shift towards the canary deployment until it is deemed to replace the previous main application, in steps such as 5%/95%, 10%/90%, 50%/50%, and finally 100%/0%.
+
+A few conditions must hold for service weights to be applied correctly:
+
+- The associated service backends must share the same path and host.
+- The total percentage shared across all service backends must yield 100% (see the section on [omitting the final service](#omitting-the-final-service), however).
+- The percentage values are interpreted as floating point numbers to a supported precision as defined in the [annotation documentation](/configuration/backends/kubernetes#general-annotations).
+
+### Omitting the Final Service
+
+When specifying service weights, it is possible to omit exactly one service for convenience reasons.
+
+For instance, the following definition shows how to split requests in a scenario where a canary release is accompanied by a baseline deployment for easier metrics comparison or automated canary analysis:
+
+```yaml
+apiVersion: extensions/v1beta1
+kind: Ingress
+metadata:
+  annotations:
+    traefik.ingress.kubernetes.io/service-weights: |
+      my-app-canary: 10%
+      my-app-baseline: 10%
+  name: app
+spec:
+  rules:
+  - http:
+      paths:
+      - backend:
+          serviceName: my-app-canary
+          servicePort: 80
+        path: /
+      - backend:
+          serviceName: my-app-baseline
+          servicePort: 80
+        path: /
+      - backend:
+          serviceName: my-app-main
+          servicePort: 80
+        path: /
+```
+
+This configuration assigns 80% of traffic to `my-app-main` automatically, thus freeing the user from having to complete percentage values manually.
+This becomes handy when increasing shares for canary releases continuously.
