Træfɪk is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease.
|
||||
It supports several backends ([Docker :whale:](https://www.docker.com/), [Swarm :whale: :whale:](https://docs.docker.com/swarm), [Mesos/Marathon](https://mesosphere.github.io/marathon/), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Zookeeper](https://zookeeper.apache.org), [BoltDB](https://github.com/boltdb/bolt), Rest API, file...) to manage its configuration automatically and dynamically.

It supports several backends ([Docker](https://www.docker.com/), [Swarm](https://docs.docker.com/swarm), [Mesos/Marathon](https://mesosphere.github.io/marathon/), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Zookeeper](https://zookeeper.apache.org), [BoltDB](https://github.com/boltdb/bolt), Rest API, file...) to manage its configuration automatically and dynamically.
|
||||
|
||||
## Overview
|
||||
|
||||
Imagine that you have deployed a bunch of microservices on your infrastructure. You probably used a service registry (like etcd or consul) and/or an orchestrator (swarm, Mesos/Marathon) to manage all these services.
|
||||
If you want your users to access some of your microservices from the Internet, you will have to use a reverse proxy and configure it using virtual hosts or prefix paths:
|
||||
|
||||
- domain `api.domain.com` will point the microservice `api` in your private network
|
||||
- path `domain.com/web` will point the microservice `web` in your private network
|
||||
- domain `backoffice.domain.com` will point the microservices `backoffice` in your private network, load-balancing between your multiple instances
|
||||
|
||||
But a microservices architecture is dynamic... Services are added, removed, killed or upgraded often, eventually several times a day.
|
||||
|
||||
Traditional reverse-proxies are not natively dynamic. You can't change their configuration and hot-reload easily.
|
||||
|
||||
Here enters Træfɪk.
|
||||
|
||||
|
||||
|
||||
Træfɪk can listen to your service registry/orchestrator API, and knows each time a microservice is added, removed, killed or upgraded, and can generate its configuration automatically.
|
||||
Routes to your services will be created instantly.
|
||||
|
||||
Run it and forget it!

# Concepts
|
||||
|
||||
Let's take our example from the [overview](https://docs.traefik.io/#overview) again:
|
||||
|
||||
|
||||
> Imagine that you have deployed a bunch of microservices on your infrastructure. You probably used a service registry (like etcd or consul) and/or an orchestrator (swarm, Mesos/Marathon) to manage all these services.

|
||||
> - domain `backoffice.domain.com` will point the microservices `backoffice` in your private network, load-balancing between your multiple instances
|
||||
|
||||
> 
|
||||
|
||||
Let's zoom on Træfɪk and have an overview of its internal architecture:
|
||||
|
||||
|
||||
|
||||
|
||||
- Incoming requests end on [entrypoints](#entrypoints), as the name suggests, they are the network entry points into Træfɪk (listening port, SSL, traffic redirection...).
|
||||
- Traffic is then forwared to a matching [frontend](#frontends). A frontend defines routes from [entrypoints](#entrypoints) to [backends](#backends).
|
||||
Routes are created using requests fields (`Host`, `Path`, `Headers`...) and can match or not a request.
|
||||
- The [frontend](#frontends) will then send the request to a [backend](#backends). A backend can be composed by one or more [servers](#servers), and by a load-balancing strategy.
|
||||
- Finally, the [server](#servers) will forward the request to the corresponding microservice in the private network.
|
||||
|
||||
## Entrypoints
|
||||
|
||||
Entrypoints are the network entry points into Træfɪk.
|
||||
They can be defined using:
|
||||
|
||||
- a port (80, 443...)
|
||||
- SSL (Certificates. Keys...)
|
||||
- redirection to another entrypoint (redirect `HTTP` to `HTTPS`)
|
||||
|
||||
Here is an example of entrypoints definition:
|
||||
|
||||
```toml
|
||||
[entryPoints]
|
||||
[entryPoints.http]
|
||||
address = ":80"
|
||||
[entryPoints.http.redirect]
|
||||
entryPoint = "https"
|
||||
[entryPoints.https]
|
||||
address = ":443"
|
||||
[entryPoints.https.tls]
|
||||
[[entryPoints.https.tls.certificates]]
|
||||
certFile = "tests/traefik.crt"
|
||||
keyFile = "tests/traefik.key"
|
||||
```
|
||||
|
||||
- Two entrypoints are defined `http` and `https`.
|
||||
- `http` listens on port `80` et `https` on port `443`.
|
||||
- We enable SSL en `https` by giving a certificate and a key.
|
||||
- We also redirect all the traffic from entrypoint `http` to `https`.
|
||||
|
||||
## Frontends
|
||||
|
||||
A frontend is a set of rules that forwards the incoming traffic from an entrypoint to a backend.
|
||||
Frontends can be defined using the following rules:
|
||||
|
||||
- `Headers`: Headers adds a matcher for request header values. It accepts a sequence of key/value pairs to be matched. For example: `Content-Type, application/json`
|
||||
- `HeadersRegexp`: Regular expressions can be used with headers as well. It accepts a sequence of key/value pairs, where the value has regex support. For example: `Content-Type, application/(text|json)`
|
||||
- `Host`: Host adds a matcher for the URL host. It accepts a template with zero or more URL variables enclosed by `{}`. Variables can define an optional regexp pattern to be matched: `www.traefik.io`, `{subdomain:[a-z]+}.traefik.io`
|
||||
- `Methods`: Methods adds a matcher for HTTP methods. It accepts a sequence of one or more methods to be matched, e.g.: `GET`, `POST`, `PUT`
|
||||
- `Path`: Path adds a matcher for the URL path. It accepts a template with zero or more URL variables enclosed by `{}`. The template must start with a `/`. For exemple `/products/` `/articles/{category}/{id:[0-9]+}`
|
||||
- `PathStrip`: Same as `Path` but strip the given prefix from the request URL's Path.
|
||||
- `PathPrefix`: PathPrefix adds a matcher for the URL path prefix. This matches if the given template is a prefix of the full URL path.
|
||||
- `PathPrefixStrip`: Same as `PathPrefix` but strip the given prefix from the request URL's Path.
|
||||
|
||||
You can optionally enable `passHostHeader` to forward client `Host` header to the backend.
|
||||
|
||||
Here is an example of frontends definition:
|
||||
|
||||
```toml
|
||||
[frontends]
|
||||
[frontends.frontend1]
|
||||
backend = "backend2"
|
||||
[frontends.frontend1.routes.test_1]
|
||||
rule = "Host:test.localhost"
|
||||
[frontends.frontend2]
|
||||
backend = "backend1"
|
||||
passHostHeader = true
|
||||
entrypoints = ["https"] # overrides defaultEntryPoints
|
||||
[frontends.frontend2.routes.test_1]
|
||||
rule = "Host:{subdomain:[a-z]+}.localhost"
|
||||
[frontends.frontend3]
|
||||
backend = "backend2"
|
||||
rule = "Path:/test"
|
||||
```
|
||||
|
||||
- Three frontends are defined: `frontend1`, `frontend2` and `frontend3`
|
||||
- `frontend1` will forward the traffic to the `backend2` if the rule `Host:test.localhost` is matched
|
||||
- `frontend2` will forward the traffic to the `backend1` if the rule `Host:{subdomain:[a-z]+}.localhost` is matched (forwarding client `Host` header to the backend)
|
||||
- `frontend3` will forward the traffic to the `backend2` if the rule `Path:/test` is matched
|
||||
|
||||
## Backends
|
||||
|
||||
A backend is responsible to load-balance the traffic coming from one or more frontends to a set of http servers.
|
||||
Various methods of load-balancing is supported:
|
||||
|
||||
- `wrr`: Weighted Round Robin
|
||||
- `drr`: Dynamic Round Robin: increases weights on servers that perform better than others. It also rolls back to original weights if the servers have changed.
|
||||
|
||||
A circuit breaker can also be applied to a backend, preventing high loads on failing servers.
|
||||
Initial state is Standby. CB observes the statistics and does not modify the request.
|
||||
In case if condition matches, CB enters Tripped state, where it responds with predefines code or redirects to another frontend.
|
||||
Once Tripped timer expires, CB enters Recovering state and resets all stats.
|
||||
In case if the condition does not match and recovery timer expries, CB enters Standby state.
|
||||
|
||||
It can be configured using:
|
||||
|
||||
- Methods: `LatencyAtQuantileMS`, `NetworkErrorRatio`, `ResponseCodeRatio`
|
||||
- Operators: `AND`, `OR`, `EQ`, `NEQ`, `LT`, `LE`, `GT`, `GE`
|
||||
|
||||
For example:
|
||||
|
||||
- `NetworkErrorRatio() > 0.5`: watch error ratio over 10 second sliding window for a frontend
|
||||
- `LatencyAtQuantileMS(50.0) > 50`: watch latency at quantile in milliseconds.
|
||||
- `ResponseCodeRatio(500, 600, 0, 600) > 0.5`: ratio of response codes in range [500-600) to [0-600)
|
||||
|
||||
## Servers
|
||||
|
||||
Servers are simply defined using a `URL`. You can also apply a custom `weight` to each server (this will be used by load-balacning).
|
||||
|
||||
Here is an example of backends and servers definition:
|
||||
|
||||
```toml
|
||||
[backends]
|
||||
[backends.backend1]
|
||||
[backends.backend1.circuitbreaker]
|
||||
expression = "NetworkErrorRatio() > 0.5"
|
||||
[backends.backend1.servers.server1]
|
||||
url = "http://172.17.0.2:80"
|
||||
weight = 10
|
||||
[backends.backend1.servers.server2]
|
||||
url = "http://172.17.0.3:80"
|
||||
weight = 1
|
||||
[backends.backend2]
|
||||
[backends.backend2.LoadBalancer]
|
||||
method = "drr"
|
||||
[backends.backend2.servers.server1]
|
||||
url = "http://172.17.0.4:80"
|
||||
weight = 1
|
||||
[backends.backend2.servers.server2]
|
||||
url = "http://172.17.0.5:80"
|
||||
weight = 2
|
||||
```
|
||||
|
||||
- Two backends are defined: `backend1` and `backend2`
|
||||
- `backend1` will forward the traffic to two servers: `http://172.17.0.2:80"` with weight `10` and `http://172.17.0.3:80` with weight `1` using default `wrr` load-balancing strategy.
|
||||
- `backend2` will forward the traffic to two servers: `http://172.17.0.4:80"` with weight `1` and `http://172.17.0.5:80` with weight `2` using `drr` load-balancing strategy.
|
||||
- a circuit breaker is added on `backend1` using the expression `NetworkErrorRatio() > 0.5`: watch error ratio over 10 second sliding window
|
||||
|
||||
# Launch
|
||||
|
||||
Træfɪk can be configured using a TOML file configuration, arguments, or both.
|
||||
By default, Træfɪk will try to find a `traefik.toml` in the following places:
|
||||
|
||||
- `/etc/traefik/`
|
||||
- `$HOME/.traefik/`
|
||||
- `.` *the working directory*
|
||||
|
||||
You can override this by setting a `configFile` argument:
|
||||
|
||||
```bash
|
||||
$ traefik --configFile=foo/bar/myconfigfile.toml
|
||||
```
|
||||
|
||||
Træfɪk uses the following precedence order. Each item takes precedence over the item below it:
|
||||
|
||||
- arguments
|
||||
- configuration file
|
||||
- default
|
||||
|
||||
It means that arguments overrides configuration file.
|
||||
Each argument is described in the help section:
|
||||
|
||||
```bash
|
||||
$ traefik --help
|
||||
```

## File backend
|
||||
|
||||
Like any other reverse proxy, Træfɪk can be configured with a file. You have two choices:
|
||||
|
||||
- simply add your configuration at the end of the global configuration file `traefik.toml` :
|
||||
|
||||
```toml
|
||||
# traefik.toml
|
||||
logLevel = "DEBUG"
|
||||
defaultEntryPoints = ["http", "https"]
|
||||
[entryPoints]
|

[entryPoints.http]
|
||||
address = ":80"
|

[entryPoints.http.redirect]
|
||||
entryPoint = "https"
|

If you want Træfɪk to watch file changes automatically, just add:
|
||||
|
||||
```toml
|
||||
[file]
|
||||
watch = true
|
||||
```
|
||||
|
||||
## API backend
|
||||
|
||||
Træfik can be configured using a restful api.
|
||||
To enable it:
|
||||
|
||||
```toml
|
||||
[web]
|
||||
address = ":8080"
|
||||
|
||||
# SSL certificate and key used
|
||||
#
|
||||
# Optional
|
||||
#
|
||||
# CertFile = "traefik.crt"
|
||||
# KeyFile = "traefik.key"
|
||||
#
|
||||
# Set REST API to read-only mode
|
||||
#
|
||||
# Optional
|
||||
# ReadOnly = false
|
||||
```
|

## Docker backend
|
||||
|

|
||||
#
|
||||
endpoint = "unix:///var/run/docker.sock"
|
||||
|
||||
# Default domain used.
|
||||
# Can be overridden by setting the "traefik.domain" label on a container.
|
||||
#
|
||||
# Required
|

# insecureskipverify = true
|
||||
```
|
||||
|
||||
Labels can be used on containers to override default behaviour:
|
||||
|
||||
- `traefik.backend=foo`: assign the container to `foo` backend
|
||||
- `traefik.port=80`: register this port. Useful when the container exposes multiples ports.
|
||||
- `traefik.protocol=https`: override the default `http` protocol
|
||||
- `traefik.weight=10`: assign this weight to the container
|
||||
- `traefik.enable=false`: disable this container in Træfɪk
|
||||
- `traefik.frontend.rule=Host:test.traefik.io`: override the default frontend rule (Default: `Host:{containerName}.{domain}`). See [frontends](#frontends).
|
||||
- `traefik.frontend.passHostHeader=true`: forward client `Host` header to the backend.
|
||||
- `traefik.frontend.entryPoints=http,https`: assign this frontend to entry points `http` and `https`. Overrides `defaultEntryPoints`.
|
||||
* `traefik.domain=traefik.localhost`: override the default domain
|
||||
|
||||
|
||||
## Marathon backend
|
||||
|

|

|

## Key-value storage structure
|
||||
|
||||
The Keys-Values structure should look (using `prefix = "/traefik"`):
|
||||
|
||||
- backend 1
|
||||
|
||||
| Key | Value |
|
||||
|--------------------------------------------------------|-----------------------------|
|
||||
| `/traefik/backends/backend1/circuitbreaker/expression` | `NetworkErrorRatio() > 0.5` |
|
||||
| `/traefik/backends/backend1/servers/server1/url` | `http://172.17.0.2:80` |
|
||||
| `/traefik/backends/backend1/servers/server1/weight` | `10` |
|
||||
| `/traefik/backends/backend1/servers/server2/url` | `http://172.17.0.3:80` |
|
||||
| `/traefik/backends/backend1/servers/server2/weight` | `1` |
|
||||
|
||||
- backend 2
|
||||
|
||||
| Key | Value |
|
||||
|-----------------------------------------------------|------------------------|
|
||||
| `/traefik/backends/backend2/loadbalancer/method` | `drr` |
|
||||
| `/traefik/backends/backend2/servers/server1/url` | `http://172.17.0.4:80` |
|
||||
| `/traefik/backends/backend2/servers/server1/weight` | `1` |
|
||||
| `/traefik/backends/backend2/servers/server2/url` | `http://172.17.0.5:80` |
|
||||
| `/traefik/backends/backend2/servers/server2/weight` | `2` |
|
||||
|
||||
- frontend 1
|
||||
|
||||
| Key | Value |
|
||||
|---------------------------------------------------|-----------------------|
|
||||
| `/traefik/frontends/frontend1/backend` | `backend2` |
|
||||
| `/traefik/frontends/frontend1/routes/test_1/rule` | `Host:test.localhost` |
|
||||
|
||||
- frontend 2
|
||||
|
||||
| Key | Value |
|
||||
|----------------------------------------------------|--------------|
|
||||
| `/traefik/frontends/frontend2/backend` | `backend1` |
|
||||
| `/traefik/frontends/frontend2/passHostHeader` | `true` |
|
||||
| `/traefik/frontends/frontend2/entrypoints` | `http,https` |
|
||||
| `/traefik/frontends/frontend2/routes/test_2/rule` | `Path:/test` |
|
||||
|
||||
## Atomic configuration changes
|
||||
|
||||
The [Etcd](https://github.com/coreos/etcd/issues/860) and [Consul](https://github.com/hashicorp/consul/issues/886) backends do not support updating multiple keys atomically. As a result, it may be possible for Træfɪk to read an intermediate configuration state despite judicious use of the `--providersThrottleDuration` flag. To solve this problem, Træfɪk supports a special key called `/traefik/alias`. If set, Træfɪk use the value as an alternative key prefix.
|
||||
|
||||
Given the key structure below, Træfɪk will use the `http://172.17.0.2:80` as its only backend (frontend keys have been omitted for brevity).
|
||||
|
||||
| Key | Value |
|
||||
|-------------------------------------------------------------------------|-----------------------------|
|
||||
| `/traefik/alias` | `/traefik_configurations/1` |
|
||||
| `/traefik_configurations/1/backends/backend1/servers/server1/url` | `http://172.17.0.2:80` |
|
||||
| `/traefik_configurations/1/backends/backend1/servers/server1/weight` | `10` |
|
||||
|
||||
When an atomic configuration change is required, you may write a new configuration at an alternative prefix. Here, although the `/traefik_configurations/2/...` keys have been set, the old configuration is still active because the `/traefik/alias` key still points to `/traefik_configurations/1`:
|
||||
|
||||
| Key | Value |
|
||||
|-------------------------------------------------------------------------|-----------------------------|
|
||||
| `/traefik/alias` | `/traefik_configurations/1` |
|
||||
| `/traefik_configurations/1/backends/backend1/servers/server1/url` | `http://172.17.0.2:80` |
|
||||
| `/traefik_configurations/1/backends/backend1/servers/server1/weight` | `10` |
|
||||
| `/traefik_configurations/2/backends/backend1/servers/server1/url` | `http://172.17.0.2:80` |
|
||||
| `/traefik_configurations/2/backends/backend1/servers/server1/weight` | `5` |
|
||||
| `/traefik_configurations/2/backends/backend1/servers/server2/url` | `http://172.17.0.3:80` |
|
||||
| `/traefik_configurations/2/backends/backend1/servers/server2/weight` | `5` |
|
||||
|
||||
Once the `/traefik/alias` key is updated, the new `/traefik_configurations/2` configuration becomes active atomically. Here, we have a 50% balance between the `http://172.17.0.3:80` and the `http://172.17.0.4:80` hosts while no traffic is sent to the `172.17.0.2:80` host:
|
||||
|
||||
| Key | Value |
|
||||
|-------------------------------------------------------------------------|-----------------------------|
|
||||
| `/traefik/alias` | `/traefik_configurations/2` |
|
||||
| `/traefik_configurations/1/backends/backend1/servers/server1/url` | `http://172.17.0.2:80` |
|
||||
| `/traefik_configurations/1/backends/backend1/servers/server1/weight` | `10` |
|
||||
| `/traefik_configurations/2/backends/backend1/servers/server1/url` | `http://172.17.0.3:80` |
|
||||
| `/traefik_configurations/2/backends/backend1/servers/server1/weight` | `5` |
|
||||
| `/traefik_configurations/2/backends/backend1/servers/server2/url` | `http://172.17.0.4:80` |
|
||||
| `/traefik_configurations/2/backends/backend1/servers/server2/weight` | `5` |
|
||||
|
||||
Note that Træfɪk *will not watch for key changes in the `/traefik_configurations` prefix*. It will only watch for changes in the `/traefik` prefix. Further, if the `/traefik/alias` key is set, all other sibling keys with the `/traefik` prefix are ignored.
