# Traefik & Consul

A Story of KV store & Containers
{: .subtitle }

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

## Routing Configuration

See the dedicated section in [routing](../routing/providers/kv.md).

## Provider Configuration

### `endpoints`

_Required, Default="127.0.0.1:8500"_

Defines how to access Consul.

```yaml tab="File (YAML)"
providers:
  consul:
    endpoints:
      - "127.0.0.1:8500"
```

```toml tab="File (TOML)"
[providers.consul]
  endpoints = ["127.0.0.1:8500"]
```

```bash tab="CLI"
--providers.consul.endpoints=127.0.0.1:8500
```

### `rootKey`

_Required, Default="traefik"_

Defines the root key of the configuration.

```yaml tab="File (YAML)"
providers:
  consul:
    rootKey: "traefik"
```

```toml tab="File (TOML)"
[providers.consul]
  rootKey = "traefik"
```

```bash tab="CLI"
--providers.consul.rootkey=traefik
```

### `namespace`

??? warning "Deprecated in favor of the [`namespaces`](#namespaces) option."

    _Optional, Default=""_
    
    The `namespace` option defines the namespace to query.

        The namespace option only works with [Consul Enterprise](https://www.consul.io/docs/enterprise),
        which provides the [Namespaces](https://www.consul.io/docs/enterprise/namespaces) feature.
    
    !!! warning
    
        One should only define either the `namespaces` option or the `namespace` option.

    providers:
      consul:
        # ...
        namespace: "production"
    ```
    
    ```toml tab="File (TOML)"
    [providers.consul]
      # ...
      namespace = "production"
    ```
    
    ```bash tab="CLI"
    --providers.consul.namespace=production
    ```

### `namespaces`

_Optional, Default=""_

The `namespaces` option defines the namespaces to query.
When using the `namespaces` option, the discovered configuration object names will be suffixed as shown below:

```text
<resource-name>@consul-<namespace>
```

!!! warning

    The namespaces option only works with [Consul Enterprise](https://www.consul.io/docs/enterprise),
    which provides the [Namespaces](https://www.consul.io/docs/enterprise/namespaces) feature.

    # ...
```

```toml tab="File (TOML)"
[providers.consul]
  namespaces = ["ns1", "ns2"]
  # ...
```

```bash tab="CLI"
--providers.consul.namespaces=ns1,ns2
# ...
```

### `username`

```

### `tls`

_Optional_

Defines the TLS configuration used for the secure connection to Consul.

it defaults to the system bundle.

```yaml tab="File (YAML)"
providers:
  consul:
    tls:
      ca: path/to/ca.crt
```

```toml tab="File (TOML)"

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

```bash tab="CLI"
--providers.consul.tls.ca=path/to/ca.crt
```

#### `cert`

_Optional_

`cert` is the path to the public certificate used for the secure connection to Consul.
When using this option, setting the `key` option is required.

```yaml tab="File (YAML)"

  consul:
    tls:
      cert: path/to/foo.cert
      key: path/to/foo.key
```

```toml tab="File (TOML)"
[providers.consul.tls]
  cert = "path/to/foo.cert"
  key = "path/to/foo.key"
```

```bash tab="CLI"
--providers.consul.tls.cert=path/to/foo.cert
--providers.consul.tls.key=path/to/foo.key
```

#### `key`

--providers.consul.tls.key=path/to/foo.key
```

#### `insecureSkipVerify`

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

```yaml tab="File (YAML)"

  consul:
    tls:
      insecureSkipVerify: true
```

```toml tab="File (TOML)"
[providers.consul.tls]
  insecureSkipVerify = true
```

```bash tab="CLI"
--providers.consul.tls.insecureSkipVerify=true
```
