|
||||
- `traefik.protocol=https`: override the default `http` protocol

## Frontends
|
||||
### Frontends
|
||||
|
||||
A frontend consists of a set of rules that determine how incoming requests are forwarded from an entrypoint to a backend.
|
||||
|
||||
Rules may be classified in one of two groups: Modifiers and matchers.
|
||||
|
||||
### Modifiers
|
||||
#### Modifiers
|
||||
|
||||
Modifier rules only modify the request. They do not have any impact on routing decisions being made.

||||
@ -86,7 +87,7 @@ Following is the list of existing modifier rules:

- `AddPrefix: /products`: Add path prefix to the existing request path prior to forwarding the request to the backend.

||||
- `ReplacePath: /serverless-path`: Replaces the path and adds the old path to the `X-Replaced-Path` header. Useful for mapping to AWS Lambda or Google Cloud Functions.
|
||||
|
||||
### Matchers

|
||||
|

## Notes
|
||||
|
||||
If Traefik needs access to the Rancher API, you need to set the `endpoint`, `accesskey` and `secretkey` parameters.
|
||||
|
||||
To enable traefik to fetch information about the Environment it's deployed in only, you need to create an `Environment API Key`.
|
||||
This can be found within the API Key advanced options.

Access logs are written when `[accessLog]` is defined.

# Docker & Traefik
|
||||
In this use case, we want to use Traefik as a *layer-7* load balancer with SSL termination for a set of microservices used to run a webapplication. We also want to automatically *discover any services* on the Docker host and let Traefik reconfigure itself automatically when containers get created (or shut down) so HTTP traffic can be routed accordingly. In addition, we want to use Let's Encrypt to automatically generate and renew SSL certificates per hostname.
|
||||
|
||||
## Setting up
|
||||
In order for this to work, you'll need a server with a public IP address, with Docker installed on it. In this example, we're using the fictitious domain *my-awesome-app.org*. In real-life, you'll want to use your own domain and have the DNS configured accordingly so the hostname records you'll want to use point to the aforementioned public IP address.

## Networking
|
||||
Docker containers can only communicate with each other over TCP when they share at least one network. This makes sense from a topological point of view in the context of networking, since Docker under the hood creates IPTable rules so containers can't reach other containers *unless you'd want to*. In this example, we're going to use a single network called `web` where all containers that are handling HTTP traffic (including Traefik) will reside in.

### Labels

As mentioned earlier, we don't want containers exposed automatically by Traefik. The reason behind this is simple: we want to have control over this process ourselves. Thanks to Docker labels, we can tell Traefik how to create it's internal routing configuration. Let's take a look at the labels themselves for the `app` service, which is a HTTP webservice listing on port 9000:

As mentioned earlier, we don't want containers exposed automatically by Traefik.
|
||||
The reason behind this is simple: we want to have control over this process ourselves.
|
||||
Thanks to Docker labels, we can tell Traefik how to create it's internal routing configuration.
|
||||
Let's take a look at the labels themselves for the `app` service, which is a HTTP webservice listing on port 9000:
|
||||
|
||||
```yaml
|
||||
- "traefik.backend=my-awesome-app-app"

||||
@ -168,14 +189,25 @@ As mentioned earlier, we don't want containers exposed automatically by Traefik.
|
||||
- "traefik.port=9000"
|
||||
```
|
||||
|
||||
First, we specify the `backend` name which corresponds to the actual service we're routing **to**. We also tell Traefik to use the `web` network to route HTTP traffic to this container. With the `frontend.rule` label, we tell Traefik that we want to route to this container if the incoming HTTP request contains the `Host` `app.my-awesome-app.org`. Essentially, this is the actual rule used for Layer-7 load balancing. With the `traefik.enable` label, we tell Traefik to include this container in it's internal configuration. Finally but not unimportantly, we tell Traefik to route **to** port `9000`, since that is the actual TCP/IP port the container actually listens on.

|

#### Gotchas and tips
|
||||
- Always specify the correct port where the container expects HTTP traffic using `traefik.port` label. 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 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 Traefik to provide a HTTP basic-auth challenge for the endpoints you provide the label for.
|
||||
- Traefik has built-in support to automatically export [Prometheus](https://prometheus.io) metrics
|
||||
- Traefik 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. Thanks to the fact that HTTPS in our example is enforced, these websockets are automatically secure as well (WSS)

### Final thoughts
|
||||
Using Traefik as a Layer-7 load balancer in combination with both Docker and Let's Encrypt provides you with an extremely flexible, performant and self-configuring solution for your projects. With Let's Encrypt, your endpoints are automatically secured with production-ready SSL certificates that are renewed automatically as well.

the DeaemonSet. It is possible to exclusively run a Service on a dedicated

set of machines using taints and tolerations with a DaemonSet. On the other hand the
|
||||
DaemonSet allows you to access any Node directly on Port 80 and 443, where you have to setup a
