# Traefik & HTTP
2021-02-11 18:04:03 +00:00
Provide your [dynamic configuration](./overview.md) via an HTTP(S) endpoint and let Traefik do the rest!
## Routing Configuration
The HTTP provider uses the same configuration as the [File Provider](./file.md) in YAML or JSON format.
## Provider Configuration
### `endpoint`
_Required_
2021-02-11 18:04:03 +00:00
Defines the HTTP(S) endpoint to poll.
```yaml tab="File (YAML)"
providers:
http:
endpoint:
- "http://127.0.0.1:9000/api"
```
```toml tab="File (TOML)"
[providers.http]
endpoint = "http://127.0.0.1:9000/api"
```
```bash tab="CLI"
--providers.http.endpoint=http://127.0.0.1:9000/api
```
### `pollInterval`
_Optional, Default="5s"_
Defines the polling interval.
```yaml tab="File (YAML)"
providers:
http:
pollInterval: "5s"
```
```toml tab="File (TOML)"
[providers.http]
pollInterval = "5s"
```
```bash tab="CLI"
--providers.http.pollInterval=5s
```
### `pollTimeout`
_Optional, Default="5s"_
Defines the polling timeout when connecting to the endpoint.
```yaml tab="File (YAML)"
providers:
http:
pollTimeout: "5s"
```
```toml tab="File (TOML)"
[providers.http]
pollTimeout = "5s"
```
```bash tab="CLI"
--providers.http.pollTimeout=5s
```
### `tls`
_Optional_
Defines the TLS configuration used for the secure connection to the endpoint.
#### `ca`
_Optional_
`ca` is the path to the certificate authority used for the secure connection to the endpoint,
it defaults to the system bundle.
```yaml tab="File (YAML)"
providers:
http:
tls:
ca: path/to/ca.crt
```
```toml tab="File (TOML)"
[providers.http.tls]
ca = "path/to/ca.crt"
```
```bash tab="CLI"
--providers.http.tls.ca=path/to/ca.crt
```
#### `caOptional`
_Optional_
The value of `caOptional` defines which policy should be used for the secure connection with TLS Client Authentication to the endpoint.
2021-02-11 18:04:03 +00:00
!!! warning ""
If `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.
2021-02-11 18:04:03 +00:00
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.
```yaml tab="File (YAML)"
providers:
http:
tls:
caOptional: true
```
```toml tab="File (TOML)"
[providers.http.tls]
caOptional = true
```
```bash tab="CLI"
--providers.http.tls.caOptional=true
```
#### `cert`
_Optional_
`cert` is the path to the public certificate used for the secure connection to the endpoint.
When using this option, setting the `key` option is required.
```yaml tab="File (YAML)"
providers:
http:
tls:
cert: path/to/foo.cert
key: path/to/foo.key
```
```toml tab="File (TOML)"
[providers.http.tls]
cert = "path/to/foo.cert"
key = "path/to/foo.key"
```
```bash tab="CLI"
--providers.http.tls.cert=path/to/foo.cert
--providers.http.tls.key=path/to/foo.key
```
#### `key`
_Optional_
`key` is the path to the private key used for the secure connection to the endpoint.
When using this option, setting the `cert` option is required.
```yaml tab="File (YAML)"
providers:
http:
tls:
cert: path/to/foo.cert
key: path/to/foo.key
```
```toml tab="File (TOML)"
[providers.http.tls]
cert = "path/to/foo.cert"
key = "path/to/foo.key"
```
```bash tab="CLI"
--providers.http.tls.cert=path/to/foo.cert
--providers.http.tls.key=path/to/foo.key
```
#### `insecureSkipVerify`
_Optional, Default=false_
2021-02-11 18:04:03 +00:00
If `insecureSkipVerify` is `true`, the TLS connection to the endpoint accepts any certificate presented by the server regardless of the hostnames it covers.
```yaml tab="File (YAML)"
providers:
http:
tls:
insecureSkipVerify: true
```
```toml tab="File (TOML)"
[providers.http.tls]
insecureSkipVerify = true
```
```bash tab="CLI"
--providers.http.tls.insecureSkipVerify=true
```
