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.

File (YAML)

providers:
  zooKeeper:
    endpoints:
      - "127.0.0.1:2181"

File (TOML)

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

CLI

--providers.zookeeper.endpoints=127.0.0.1:2181

rootKey

Required, Default="traefik"

Defines the root key of the configuration.

File (YAML)

providers:
  zooKeeper:
    rootKey: "traefik"

File (TOML)

[providers.zooKeeper]
  rootKey = "traefik"

CLI

--providers.zookeeper.rootkey=traefik

username

Optional, Default=""

Defines a username to connect with ZooKeeper.

File (YAML)

providers:
  zooKeeper:
    # ...
    usename: "foo"

File (TOML)

[providers.zooKeeper]
  # ...
  username = "foo"

CLI

--providers.zookeeper.username=foo

password

Optional, Default=""

Defines a password to connect with ZooKeeper.

File (YAML)

providers:
  zooKeeper:
    # ...
    password: "bar"

File (TOML)

[providers.zooKeeper]
  # ...
  password = "bar"

CLI

--providers.zookeeper.password=foo

tls

Optional

tls.ca

Certificate Authority used for the secure connection to ZooKeeper.

File (YAML)

providers:
  zooKeeper:
    tls:
      ca: path/to/ca.crt

File (TOML)

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

CLI

--providers.zookeeper.tls.ca=path/to/ca.crt

tls.caOptional

The value of tls.caOptional defines which policy should be used for the secure connection with TLS Client Authentication to Zookeeper.

If tls.ca is undefined, this option will be ignored, and no client certificate will be requested during the handshake. Any provided certificate will thus never be verified.

When this option is set to true, a client certificate is requested during the handshake but is not required. If a certificate is sent, it is required to be valid.

When this option is set to false, a client certificate is requested during the handshake, and at least one valid certificate should be sent by the client.

File (YAML)

providers:
  zooKeeper:
    tls:
      caOptional: true

File (TOML)

[providers.zooKeeper.tls]
  caOptional = true

CLI

--providers.zookeeper.tls.caOptional=true

tls.cert

Public certificate used for the secure connection to ZooKeeper.

File (YAML)

providers:
  zooKeeper:
    tls:
      cert: path/to/foo.cert
      key: path/to/foo.key

File (TOML)

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

CLI

--providers.zookeeper.tls.cert=path/to/foo.cert
--providers.zookeeper.tls.key=path/to/foo.key

tls.key

Private certificate used for the secure connection to ZooKeeper.

File (YAML)

providers:
  zooKeeper:
    tls:
      cert: path/to/foo.cert
      key: path/to/foo.key

File (TOML)

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

CLI

--providers.zookeeper.tls.cert=path/to/foo.cert
--providers.zookeeper.tls.key=path/to/foo.key

tls.insecureSkipVerify

If insecureSkipVerify is true, the TLS connection to Zookeeper accepts any certificate presented by the server regardless of the hostnames it covers.

File (YAML)

providers:
  zooKeeper:
    tls:
      insecureSkipVerify: true

File (TOML)

[providers.zooKeeper.tls]
  insecureSkipVerify = true

CLI

--providers.zookeeper.tls.insecureSkipVerify=true
