# API
|
|
|
|
Traefik exposes a number of information through an API handler, such as the configuration of all routers, services, middlewares, etc.
|
|
|
|
As with all features of Traefik, this handler can be enabled with the [static configuration](../getting-started/configuration-overview.md#the-static-configuration).
|
|
|
|
## Security
|
|
|
|
Enabling the API in production is not recommended, because it will expose all configuration elements,
|
|
including sensitive data.
|
|
|
|
In production, it should be at least secured by authentication and authorizations.
|
|
|
|
A good sane default (non exhaustive) set of recommendations
|
|
would be to apply the following protection mechanisms:
|
|
|
|
* At the transport level:
|
|
NOT publicly exposing the API's port,
|
|
keeping it restricted to internal networks
|
|
(as in the [principle of least privilege](https://en.wikipedia.org/wiki/Principle_of_least_privilege), applied to networks).
|
|
|
|
## Configuration
|
|
|
|
If you enable the API, a new special `service` named `api@internal` is created and can then be referenced in a router.
|
|
|
|
To enable the API handler, use the following option on the
|
|
[static configuration](../getting-started/configuration-overview.md#the-static-configuration):
|
|
|
|
```toml tab="File (TOML)"
|
|
# Static Configuration
|
|
[api]
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
# Static Configuration
|
|
api: {}
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--api=true
|
|
```
|
|
|
|
And then define a routing configuration on Traefik itself with the
|
|
[dynamic configuration](../getting-started/configuration-overview.md#the-dynamic-configuration):
|
|
|
|
--8<-- "content/operations/include-api-examples.md"
|
|
|
|
??? warning "The router's [rule](../../routing/routers#rule) must catch requests for the URI path `/api`"
|
|
Using an "Host" rule is recommended, by catching all the incoming traffic on this host domain to the API.
|
|
However, you can also use "path prefix" rule or any combination or rules.
|
|
|
|
```bash tab="Host Rule"
|
|
# Matches http://traefik.example.com, http://traefik.example.com/api
|
|
# or http://traefik.example.com/hello
|
|
rule = "Host(`traefik.example.com`)"
|
|
```
|
|
|
|
```bash tab="Path Prefix Rule"
|
|
# Matches http://api.traefik.example.com/api or http://example.com/api
|
|
# but does not match http://api.traefik.example.com/hello
|
|
rule = "PathPrefix(`/api`)"
|
|
```
|
|
|
|
```bash tab="Combination of Rules"
|
|
# Matches http://traefik.example.com/api or http://traefik.example.com/dashboard
|
|
# but does not match http://traefik.example.com/hello
|
|
rule = "Host(`traefik.example.com`) && (PathPrefix(`/api`) || PathPrefix(`/dashboard`))"
|
|
```
|
|
|
|
### `insecure`
|
|
|
|
Enable the API in `insecure` mode, which means that the API will be available directly on the entryPoint named `traefik`.
|
|
|
|
!!! info
|
|
If the entryPoint named `traefik` is not configured, it will be automatically created on port 8080.
|
|
|
|
```toml tab="File (TOML)"
|
|
[api]
|
|
insecure = true
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
api:
|
|
insecure: true
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--api.insecure=true
|
|
```
|
|
|
|
### `dashboard`
|
|
|
|
_Optional, Default=true_
|
|
|
|
Enable the dashboard. More about the dashboard features [here](./dashboard.md).
|
|
|
|
```toml tab="File (TOML)"
|
|
[api]
|
|
dashboard = true
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
api:
|
|
dashboard: true
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--api.dashboard=true
|
|
```
|
|
|
|
!!! warning "With Dashboard enabled, the router [rule](../../routing/routers#rule) must catch requests for both `/api` and `/dashboard`"
|
|
Please check the [Dashboard documentation](./dashboard.md#dashboard-router-rule) to learn more about this and to get examples.
|
|
|
|
### `debug`
|
|
|
|
_Optional, Default=false_
|
|
|
|
Enable additional [endpoints](./api.md#endpoints) for debugging and profiling, served under `/debug/`.
|
|
|
|
```toml tab="File (TOML)"
|
|
[api]
|
|
debug = true
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
api:
|
|
debug: true
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--api.debug=true
|
|
```
|
|
|
|

|
|
|
|
All the following endpoints must be accessed with a `GET` HTTP request.
