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

File (YAML)

  1. providers:
  2. zooKeeper:
  3. # ...
  4. password: "bar"

CLI

  1. --providers.zookeeper.password=foo

tls

Optional

tls.ca

Certificate Authority used for the secured connection to ZooKeeper.

File (TOML)

  2. ca = "path/to/ca.crt"

File (YAML)

  1. providers:
  2. zooKeeper:
  3. tls:
  4. ca: path/to/ca.crt

CLI

  1. --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

File (TOML)

  1. [providers.zooKeeper.tls]
  2. caOptional = true

File (YAML)

  1. providers:
  2. zooKeeper:
  3. tls:
  4. caOptional: true

CLI

  1. --providers.zookeeper.tls.caOptional=true

tls.cert

Public certificate used for the secured connection to ZooKeeper.

File (TOML)

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

File (YAML)

  1. providers:
  2. zooKeeper:
  3. tls:
  4. cert: path/to/foo.cert
  5. key: path/to/foo.key

CLI

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

tls.key

Private certificate used for the secured connection to ZooKeeper.

File (TOML)

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

File (YAML)

  1. providers:
  2. zooKeeper:
  3. tls:
  4. cert: path/to/foo.cert
  5. key: path/to/foo.key

CLI

  1. --providers.zookeeper.tls.cert=path/to/foo.cert
  2. --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.

File (TOML)

  1. [providers.zooKeeper.tls]
  2. insecureSkipVerify = true

File (YAML)

  1. providers:
  2. zooKeeper:
  3. tls:
  4. insecureSkipVerify: true

CLI

  1. --providers.zookeeper.tls.insecureSkipVerify=true
