A Story of KV store & Containers

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

Routing Configuration

See the dedicated section in routing.

Provider Configuration

endpoints

Required, Default=”127.0.0.1:2379”

rootKey

Defines the root key of the configuration.

Required, Default=”traefik”

File (TOML)

[providers.etcd]
  rootKey = "traefik"

  etcd:
    rootKey: "traefik"

CLI

username

Defines a username to connect with Etcd.

Optional, Default=””

File (TOML)

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

File (YAML)

providers:
  etcd:
    # ...
    usename: "foo"

CLI

--providers.etcd.username=foo

password

Optional, Default=””

Defines a password to connect with Etcd.

File (TOML)

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

File (YAML)

providers:
  etcd:
    # ...
    password: "bar"

CLI

--providers.etcd.password=foo

tls

Optional

tls.ca

Certificate Authority used for the secured connection to Etcd.

File (TOML)

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

File (YAML)

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

CLI

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

tls.caOptional

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

• true: VerifyClientCertIfGiven
• false: RequireAndVerifyClientCert

• if tls.ca is undefined NoClientCert

  File (TOML)

[providers.etcd.tls]
  caOptional = true

File (YAML)

providers:
  etcd:
    tls:
      caOptional: true

CLI

--providers.etcd.tls.caOptional=true

tls.cert

Public certificate used for the secured connection to Etcd.

File (TOML)

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

File (YAML)

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

CLI

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

tls.key

Private certificate used for the secured connection to Etcd.

File (TOML)

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

File (YAML)

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

CLI

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

tls.insecureSkipVerify

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

File (TOML)

[providers.etcd.tls]
  insecureSkipVerify = true

File (YAML)

providers:
  etcd:
    tls:
      insecureSkipVerify: true

CLI

--providers.etcd.tls.insecureSkipVerify=true
