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 behavior 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.
The Træfik ACME client library [LEGO](https://github.com/xenolf/lego) supports some but not all DNS providers to work around this issue.

If a container exposes multiple ports, Træfik may forward traffic to the wrong port.
If a container exposes multiple ports, Traefik may forward traffic to the wrong port.
Even if a container only exposes one port, you should always write configuration defensively and explicitly.
- Should you choose to enable the `exposedByDefault` flag in the `traefik.toml` configuration, be aware that all containers that are placed in the same network as Træfik will automatically be reachable from the outside world, for everyone and everyone to see.
- Should you choose to enable the `exposedByDefault` flag in the `traefik.toml` configuration, be aware that all containers that are placed in the same network as Traefik will automatically be reachable from the outside world, for everyone and everyone to see.
Usually, this is a bad idea.
- With the `traefik.frontend.auth.basic` label, it's possible for Træfik to provide a HTTP basic-auth challenge for the endpoints you provide the label for.
- Træfik has built-in support to automatically export [Prometheus](https://prometheus.io) metrics
- Træfik supports websockets out of the box. In the example above, the `events`-service could be a NodeJS-based application which allows clients to connect using websocket protocol.

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 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.

For such cases, it is advisable to classify Ingress objects through a label and configure the `labelSelector` option per each Traefik Deployment accordingly.
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.
The label selectors on the Traefik 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.
The way this can be done in Traefik is to specify a percentage of requests that should go into each deployment.

Now that you have a basic understanding of how Træfik can automatically create the routes to your services and load balance them, it might be time to dive into [the documentation](https://docs.traefik.io/) and let Træfik work for you!
Whatever your infrastructure is, there is probably [an available Træfik backend](https://docs.traefik.io/#supported-backends) that will do the job.
