Traefik & ZooKeeper

A Story of KV store & Containers

Store your configuration in ZooKeeper and let Traefik do the rest!

Routing Configuration

See the dedicated section in routing.

Provider Configuration

endpoints

Required, Default="127.0.0.1:2181"

Defines how to access to ZooKeeper.

[providers.zooKeeper]
  endpoints = ["127.0.0.1:2181"]
providers:
  zooKeeper:
    endpoints:
      - "127.0.0.1:2181"
--providers.zookeeper.endpoints=127.0.0.1:2181

rootKey

Defines the root key of the configuration.

Required, Default="traefik"

[providers.zooKeeper]
  rootKey = "traefik"
providers:
  zooKeeper:
    rootKey: "traefik"
--providers.zookeeper.rootkey=traefik

username

Defines a username to connect with ZooKeeper.

Optional, Default=""

[providers.zooKeeper]
  # ...
  username = "foo"
providers:
  zooKeeper:
    # ...
    usename: "foo"
--providers.zookeeper.username=foo

password

Optional, Default=""

Defines a password to connect with ZooKeeper.

[providers.zooKeeper]
  # ...
  password = "bar"
providers:
  zooKeeper:
    # ...
    password: "bar"
--providers.zookeeper.password=foo

tls

Optional

tls.ca

Certificate Authority used for the secured connection to ZooKeeper.

[providers.zooKeeper.tls]
  ca = "path/to/ca.crt"
providers:
  zooKeeper:
    tls:
      ca: path/to/ca.crt
--providers.zookeeper.tls.ca=path/to/ca.crt

tls.caOptional

Policy followed for the secured connection with TLS Client Authentication to ZooKeeper. Requires tls.ca to be defined.

  • true: VerifyClientCertIfGiven
  • false: RequireAndVerifyClientCert
  • if tls.ca is undefined NoClientCert
[providers.zooKeeper.tls]
  caOptional = true
providers:
  zooKeeper:
    tls:
      caOptional: true
--providers.zookeeper.tls.caOptional=true

tls.cert

Public certificate used for the secured connection to ZooKeeper.

[providers.zooKeeper.tls]
  cert = "path/to/foo.cert"
  key = "path/to/foo.key"
providers:
  zooKeeper:
    tls:
      cert: path/to/foo.cert
      key: path/to/foo.key
--providers.zookeeper.tls.cert=path/to/foo.cert
--providers.zookeeper.tls.key=path/to/foo.key

tls.key

Private certificate used for the secured connection to ZooKeeper.

[providers.zooKeeper.tls]
  cert = "path/to/foo.cert"
  key = "path/to/foo.key"
providers:
  zooKeeper:
    tls:
      cert: path/to/foo.cert
      key: path/to/foo.key
--providers.zookeeper.tls.cert=path/to/foo.cert
--providers.zookeeper.tls.key=path/to/foo.key

tls.insecureSkipVerify

If insecureSkipVerify is true, TLS for the connection to ZooKeeper accepts any certificate presented by the server and any host name in that certificate.

[providers.zooKeeper.tls]
  insecureSkipVerify = true
providers:
  zooKeeper:
    tls:
      insecureSkipVerify: true
--providers.zookeeper.tls.insecureSkipVerify=true
