# Log level
#
# Optional

#
# logLevel = "ERROR"

# Backends throttle duration: minimum duration between 2 events from providers
# before applying a new configuration. It avoids unnecessary reloads if multiples events
# are sent in a short amount of time.
#
# Optional
# Default: "2s"
#
# ProvidersThrottleDuration = "5s"

# If non-zero, controls the maximum idle (keep-alive) to keep per-host.  If zero, DefaultMaxIdleConnsPerHost is used.

Entrypoints definition

# Entrypoints definition
#
# Optional
# Default:
# [entryPoints]
#   [entryPoints.http]
#   address = ":80"
#
# To redirect an http entrypoint to an https entrypoint (with SNI support):

Configuration backends

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 :

# traefik.toml
logLevel = "DEBUG"
defaultEntryPoints = ["http", "https"]
[entryPoints]
  [entryPoints.http]
  address = ":80"
    [entryPoints.http.redirect]
      entryPoint = "https"
  [entryPoints.https]
  address = ":443"
    [entryPoints.https.tls]
      [[entryPoints.https.tls.certificates]]
      CertFile = "integration/fixtures/https/snitest.com.cert"
      KeyFile = "integration/fixtures/https/snitest.com.key"
      [[entryPoints.https.tls.certificates]]
      CertFile = "integration/fixtures/https/snitest.org.cert"
      KeyFile = "integration/fixtures/https/snitest.org.key"

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/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 and Consul 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`

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:

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.
