 It is not possible to request a double wildcard certificate for a domain (for example `*.*.local.com`).
-Due to ACME limitation it is not possible to define wildcards in SANs (alternative domains). Thus, the wildcard domain has to be defined as a main domain.
 Most likely the root domain should receive a certificate too, so it needs to be specified as SAN and 2 `DNS-01` challenges are executed.
 In this case the generated DNS TXT record for both domains is the same.
-Eventhough this behaviour is [DNS RFC](https://community.letsencrypt.org/t/wildcard-issuance-two-txt-records-for-the-same-name/54528/2) compliant, it can lead to problems as all DNS providers keep DNS records cached for a certain time (TTL) and this TTL can be superior to the challenge timeout making the `DNS-01` challenge fail.

+## Security Considerations
+
+### Security Challenge with the Docker Socket
+
+Traefik requires access to the docker socket to get its dynamic configuration,
+by watching the Docker API through this socket.
+
+!!! important
+    Depending on your context and your usage, accessing the Docker API without any restriction might be a security concern.
+
+As explained on the Docker documentation: ([Docker Daemon Attack Surface page](https://docs.docker.com/engine/security/#docker-daemon-attack-surface)):
+
+`[...] only **trusted** users should be allowed to control your Docker daemon [...]`
+
+If the Traefik processes (handling requests from the outside world) is attacked,
+then the attacker can access the Docker (or Swarm Mode) backend.
+
+Also, when using Swarm Mode, it is mandatory to schedule Traefik's containers on the Swarm manager nodes,
+to let Traefik accessing the Docker Socket of the Swarm manager node.

+
+### Workarounds
+
+!!! note "Improved Security"
+
+    [Traefik Enterprise](https://traefik.io/traefik-enterprise/) solves this problem by separating the control plane (connected to Docker) and the data plane (handling the requests).
+
+Another possible workaround is to expose the Docker socket over TCP, instead of the default Unix socket file.
+It allows different implementation levels of the [AAA (Authentication, Authorization, Accounting) concepts](https://en.wikipedia.org/wiki/AAA_(computer_security)), depending on your security assessment:
+
+- Authentication with Client Certificates as described in [the "Protect the Docker daemon socket" page of Docker's documentation](https://docs.docker.com/engine/security/https/)
+
+- Authorization with the [Docker Authorization Plugin Mechanism](https://docs.docker.com/engine/extend/plugins_authorization/)
+
+- Accounting at networking level, by exposing the socket only inside a Docker private network, only available for Traefik.
+
+- Accounting at container level, by exposing the socket on a another container than Traefik's.
+  With Swarm mode, it allows scheduling of Traefik on worker nodes, with only the "socket exposer" container on the manager nodes.
+
+- Accounting at kernel level, by enforcing kernel calls with mechanisms like [SELinux](https://en.wikipedia.org/wiki/Security-Enhanced_Linux),
+  to only allows an identified set of actions for Traefik's process (or the "socket exposer" process).

 ## Labels: overriding default behavior
 
 ### Using Docker with Swarm Mode
 
 If you use a compose file with the Swarm mode, labels should be defined in the `deploy` part of your service.

+#### Troubleshooting
+
+If service doesn't show up in the dashboard, check the debug logs to see if the port is missing:

 ### Using Docker Compose
 
 If you are intending to use only Docker Compose commands (e.g. `docker-compose up --scale whoami=2 -d`), labels should be under your service, otherwise they will be ignored.

+[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.
 
-[2] `traefik.frontend.auth.basic.users=EXPR `:  
+[2] `traefik.frontend.auth.basic.users=EXPR`:  
 To create `user:password` pair, it's possible to use this command:  
 `echo $(htpasswd -nb user password) | sed -e s/\\$/\\$\\$/g`.  
 The result will be `user:$$apr1$$9Cv/OMGj$$ZomWQzuQbL.3TRCS81A1g/`, note additional symbol `$` makes escaping.
 
+[3] `traefik.backend.loadbalancer.swarm`:  
+If you enable this option, Traefik will use the virtual IP provided by docker swarm instead of the containers IPs.
+Which means that Traefik will not perform any kind of load balancing and will delegate this task to swarm.  
+It also means that Traefik will manipulate only one backend, not one backend per container.

+
+## usebindportip
+
+The default behavior of Traefik is to route requests to the IP/Port of the matching container.
+When setting `usebindportip` to true, you tell Traefik to use the IP/Port attached to the container's binding instead of the inner network IP/Port.
+
+When used in conjunction with the `traefik.port` label (that tells Traefik to route requests to a specific port), Traefik tries to find a binding with `traefik.port` port to select the container. If it can't find such a binding, Traefik falls back on the internal network IP of the container, but still uses the `traefik.port` that is set in the label.
+
+Below is a recap of the behavior of `usebindportip` in different situations.

 # Rancher Provider
 
-Træfik can be configured to use Rancher as a provider.
+Traefik can be configured to use Rancher as a provider.
+
+!!! important
+    This provider is specific to Rancher 1.x.
+    Rancher 2.x requires Kubernetes and does not have a metadata endpoint of its own for Traefik to query.
+    As such, Rancher 2.x users should utilize the [Kubernetes provider](./kubernetes.md) directly.

+In addition, these can "burst" up to 200 and 10 in each period respectively.

+Another way to describe the above parameters, is to use the [leaky bucket](https://en.wikipedia.org/wiki/Leaky_bucket) analogy:
+for rateset1, the size of the bucket is 200 drops, and it is leaking at a rate of 10 drop/s.
+If the incoming rate of drops falling into the bucket gets high enough that the bucket gets filled,

+This situation holds until the incoming rate gets low enough again, and remains that way, for the water level in the bucket to go down.

 ## Prerequisites
 
 1. A working Kubernetes cluster. If you want to follow along with this guide, you should setup [minikube](https://kubernetes.io/docs/getting-started-guides/minikube/) on your machine, as it is the quickest way to get a local Kubernetes cluster setup for experimentation and development.
 
+2. Setup ingress as an add-on. It can be enabled by the following command:
+
+    `minikube addons enable ingress`

 ### Role Based Access Control configuration (Kubernetes 1.6+ only)
 
 Kubernetes introduces [Role Based Access Control (RBAC)](https://kubernetes.io/docs/reference/access-authn-authz/rbac/) in 1.6+ to allow fine-grained control of Kubernetes resources and API.
 
-If your cluster is configured with RBAC, you will need to authorize Træfik to use the Kubernetes API. There are two ways to set up the proper permission: Via namespace-specific RoleBindings or a single, global ClusterRoleBinding.
+If your cluster is configured with RBAC, you will need to authorize Traefik to use the Kubernetes API. There are two ways to set up the proper permission: Via namespace-specific RoleBindings or a single, global ClusterRoleBinding.
 
-RoleBindings per namespace enable to restrict granted permissions to the very namespaces only that Træfik is watching over, thereby following the least-privileges principle. This is the preferred approach if Træfik is not supposed to watch all namespaces, and the set of namespaces does not change dynamically. Otherwise, a single ClusterRoleBinding must be employed.

 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.

 ## 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.

 In a production environment, however, it is important to set proper bounds, especially with regards to CPU:

 When in doubt, you should measure your resource needs, and adjust requests and limits accordingly.
