## 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"
|
||
[entryPoints.https]
|
||
address = ":443"

|

|
||
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
|
||
```
|
||
|
||
- `/`: provides a simple HTML frontend of Træfik
|
||
|
||
|
||
|
||
|
||
- `/health`: `GET` json metrics

## Docker backend
|
||
|
||
Træfɪk can be configured to use Docker as a backend configuration:
|
||
|
||
```toml
|
||
################################################################
|
||
# Docker configuration backend
|
||
################################################################
|
||
|
||
# Enable Docker configuration backend
|

|
||
# Docker server endpoint. Can be a tcp or a unix socket endpoint.
|
||
#
|
||
# Required
|
||
#
|
||
endpoint = "unix:///var/run/docker.sock"
|
||
|
||
# Default domain used.
|
||
# Can be overridden by setting the "traefik.domain" label on a container.
|
||
#
|
||
# Required
|
||
#
|
||
domain = "docker.localhost"
|
||
|
||
# Enable watch docker changes
|
||
#
|
||
# Optional
|
||
#
|
||

|
||
|
||
# Override default configuration template. For advanced users :)
|
||
#
|
||
# Optional
|
||
#
|
||
# filename = "docker.tmpl"
|
||
|
||
# Expose containers by default in traefik
|
||
#
|
||
# Optional
|

# Default: true
|
||
#
|

|
||
# cert = "/etc/ssl/docker.crt"
|
||
# key = "/etc/ssl/docker.key"
|
||
# 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}`).
|
||
- `traefik.frontend.passHostHeader=true`: forward client `Host` header to the backend.
|
||
- `traefik.frontend.priority=10`: override default frontend priority
|
||
- `traefik.frontend.entryPoints=http,https`: assign this frontend to entry points `http` and `https`. Overrides `defaultEntryPoints`.
|
||

||
- `traefik.backend=foo`: assign the application to `foo` backend
|
||
- `traefik.portIndex=1`: register port by index in the application's ports array. Useful when the application exposes multiple ports.
|
||
- `traefik.port=80`: register the explicit application port value. Cannot be used alongside `traefik.portIndex`.
|
||
- `traefik.protocol=https`: override the default `http` protocol
|
||
- `traefik.weight=10`: assign this weight to the application

## 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/maxconn/amount` | `10` |
|
||
| `/traefik/backends/backend2/maxconn/extractorfunc` | `request.host` |

|
||
| `/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/priority` | `10` |
|
||
| `/traefik/frontends/frontend2/entrypoints` | `http,https` |
|
||
| `/traefik/frontends/frontend2/routes/test_2/rule` | `PathPrefix:/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.
