- `HostRegexp: traefik.io, {subdomain:[a-z]+}.traefik.io`: Adds a matcher for the URL hosts. It accepts templates with zero or more URL variables enclosed by `{}`. Variables can define an optional regexp pattern to be matched.
- `Method: GET, POST, PUT`: Methods adds a matcher for HTTP methods. It accepts a sequence of one or more methods to be matched.

To proactively prevent backends from being overwhelmed with high load, a maximum connection limit can
also be applied to each backend.
Maximum connections can be configured by specifying an integer value for `maxconn.amount` and
`maxconn.extractorfunc` which is a strategy used to determine how to categorize requests in order to
evaluate the maximum connections.
For example:
```toml
[backends]
[backends.backend1]
[backends.backend1.maxconn]
amount = 10
extractorfunc = "request.host"
```
- `backend1` will return `HTTP code 429 Too Many Requests` if there are already 10 requests in progress for the same Host header.
- Another possible value for `extractorfunc` is `client.ip` which will categorize requests based on client source ip.
- Lastly `extractorfunc` can take the value of `request.header.ANY_HEADER` which will categorize requests based on `ANY_HEADER` that you provide.

Servers are simply defined using a `URL`. You can also apply a custom `weight` to each server (this will be used by load-balacning).

# Benchmarks
Here are some early Benchmarks between Nginx, HA-Proxy and Træfɪk acting as simple load balancers between two servers.
## Configuration
- Nginx:
I would like to thanks [vincentbernat](https://github.com/vincentbernat) from [exoscale.ch](https://www.exoscale.ch) who kindly provided the infrastructure needed for the benchmarks.
```sh
$ docker run -d -e VIRTUAL_HOST=test.nginx.localhost emilevauge/whoami
$ docker run -d -e VIRTUAL_HOST=test.nginx.localhost emilevauge/whoami

I used 4 VMs for the tests with the following configuration:
- 32 GB RAM
- 8 CPU Cores
- 10 GB SSD
- Ubuntu 14.04 LTS 64-bit
## Setup
1. One VM used to launch the benchmarking tool [wrk](https://github.com/wg/wrk)
2. One VM for traefik (v1.0.0-beta.416) / nginx (v1.4.6)
3. Two VMs for 2 backend servers in go [whoami](https://github.com/emilevauge/whoamI/)
Each VM has been tuned using the following limits:
```bash

## Conclusion
Traefik is obviously slower than Nginx, but not so much: Traefik can serve 28392 requests/sec and Nginx 33591 requests/sec which gives a ratio of 85%.
Not bad for young project :) !
Some areas of possible improvements:
- Use [GO_REUSEPORT](https://github.com/kavu/go_reuseport) listener
- Run a separate server instance per CPU core with `GOMAXPROCS=1` (it appears during benchmarks that there is a lot more context switches with traefik than with nginx)

# Swarm cluster
This section explains how to create a multi-host [swarm](https://docs.docker.com/swarm) cluster using [docker-machine](https://docs.docker.com/machine/) and how to deploy Træfɪk on it.
The cluster will be made of:
- 2 servers
- 1 swarm master
- 2 swarm nodes
- 1 [overlay](https://docs.docker.com/engine/userguide/networking/dockernetworks/#an-overlay-network) network (multi-host networking)
## Prerequisites
1. You will need to install [docker-machine](https://docs.docker.com/machine/)
2. You will need the latest [VirtualBox](https://www.virtualbox.org/wiki/Downloads)
## Cluster provisioning
We will first follow [this guide](https://docs.docker.com/engine/userguide/networking/get-started-overlay/) to create the cluster.
### Create machine `mh-keystore`
This machine will be the service registry of our cluster.
```sh
docker-machine create -d virtualbox mh-keystore
```
Then we install the service registry [Consul](https://consul.io) on this machine:
```sh
eval "$(docker-machine env mh-keystore)"
docker run -d \
-p "8500:8500" \
-h "consul" \
progrium/consul -server -bootstrap
```
### Create machine `mhs-demo0`
This machine will have a swarm master and a swarm agent on it.
```sh
docker-machine create -d virtualbox \
--swarm --swarm-master \
--swarm-discovery="consul://$(docker-machine ip mh-keystore):8500" \
--engine-opt="cluster-store=consul://$(docker-machine ip mh-keystore):8500" \
--engine-opt="cluster-advertise=eth1:2376" \
mhs-demo0
```
### Create machine `mhs-demo1`
This machine will have a swarm agent on it.
```sh
docker-machine create -d virtualbox \
--swarm \
--swarm-discovery="consul://$(docker-machine ip mh-keystore):8500" \
--engine-opt="cluster-store=consul://$(docker-machine ip mh-keystore):8500" \
--engine-opt="cluster-advertise=eth1:2376" \
mhs-demo1
```
### Create the overlay Network
Create the overlay network on the swarm master:
```sh
eval $(docker-machine env --swarm mhs-demo0)
docker network create --driver overlay --subnet=10.0.9.0/24 my-net
```
## Deploy Træfɪk
Deploy Træfɪk:
```sh
docker $(docker-machine config mhs-demo0) run \
-d \
-p 80:80 -p 8080:8080 \
--net=my-net \
-v /var/lib/boot2docker/:/ssl \
traefik \
-l DEBUG \
-c /dev/null \
--docker \
--docker.domain traefik \
--docker.endpoint tcp://$(docker-machine ip mhs-demo0):3376 \
--docker.tls \
--docker.tls.ca /ssl/ca.pem \
--docker.tls.cert /ssl/server.pem \
--docker.tls.key /ssl/server-key.pem \
--docker.tls.insecureSkipVerify \
--docker.watch \
--web
```
Let's explain this command:
- `-p 80:80 -p 8080:8080`: we bind ports 80 and 8080
- `--net=my-net`: run the container on the network my-net
- `-v /var/lib/boot2docker/:/ssl`: mount the ssl keys generated by docker-machine
- `-c /dev/null`: empty config file
- `--docker`: enable docker backend
- `--docker.endpoint tcp://172.18.0.1:3376`: connect to the swarm master using the docker_gwbridge network
- `--docker.tls`: enable TLS using the docker-machine keys
- `--web`: activate the webUI on port 8080
## Deploy your apps
We can now deploy our app on the cluster, here [whoami](https://github.com/emilevauge/whoami), a simple web server in GO, on the network `my-net`:
```sh
eval $(docker-machine env --swarm mhs-demo0)
docker run -d --name=whoami0 --net=my-net --env="constraint:node==mhs-demo0" emilevauge/whoami
docker run -d --name=whoami1 --net=my-net --env="constraint:node==mhs-demo1" emilevauge/whoami
```
Check that everything is started:
```sh
docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ba2c21488299 emilevauge/whoami "/whoamI" 8 seconds ago Up 9 seconds 80/tcp mhs-demo1/whoami1
8147a7746e7a emilevauge/whoami "/whoamI" 19 seconds ago Up 20 seconds 80/tcp mhs-demo0/whoami0
8fbc39271b4c traefik "/traefik -l DEBUG -c" 36 seconds ago Up 37 seconds 192.168.99.101:80->80/tcp, 192.168.99.101:8080->8080/tcp mhs-demo0/serene_bhabha
```
## Access to your apps through Træfɪk
