# Ping
|
|
|
|
Checking the Health of Your Traefik Instances
|
|
{: .subtitle }
|
|
|
|
## Configuration Examples
|
|
|
|
To enable the API handler:
|
|
|
|
```yaml tab="File (YAML)"
|
|
ping: {}
|
|
```
|
|
|
|
```toml tab="File (TOML)"
|
|
[ping]
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--ping=true
|
|
```
|
|
|
|
## Configuration Options
|
|
|
|
The `/ping` health-check URL is enabled with the command-line `--ping` or config file option `[ping]`.
|
|
|
|
The `entryPoint` where the `/ping` is active can be customized with the `entryPoint` option,
|
|
whose default value is `traefik` (port `8080`).
|
|
|
|
| Path | Method | Description |
|
|
|---------|---------------|-----------------------------------------------------------------------------------------------------|
|
|
| `/ping` | `GET`, `HEAD` | An endpoint to check for Traefik process liveness. Return a code `200` with the content: `OK` |
|
|
|
|
!!! note
|
|
The `cli` comes with a [`healthcheck`](./cli.md#healthcheck) command which can be used for calling this endpoint.
|
|
|
|
### `entryPoint`
|
|
|
|
_Optional, Default="traefik"_
|
|
|
|
Enabling /ping on a dedicated EntryPoint.
|
|
|
|
```yaml tab="File (YAML)"
|
|
entryPoints:
|
|
ping:
|
|
address: ":8082"
|
|
|
|
ping:
|
|
entryPoint: "ping"
|
|
```
|
|
|
|
```toml tab="File (TOML)"
|
|
[entryPoints]
|
|
[entryPoints.ping]
|
|
address = ":8082"
|
|
|
|
[ping]
|
|
entryPoint = "ping"
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--entryPoints.ping.address=:8082
|
|
--ping.entryPoint=ping
|
|
```
|
|
|
|
### `manualRouting`
|
|
|
|
_Optional, Default=false_
|
|
|
|
If `manualRouting` is `true`, it disables the default internal router in order to allow one to create a custom router for the `ping@internal` service.
|
|
|
|
```yaml tab="File (YAML)"
|
|
ping:
|
|
manualRouting: true
|
|
```
|
|
|
|
```toml tab="File (TOML)"
|
|
[ping]
|
|
manualRouting = true
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--ping.manualrouting=true
|
|
```
|
|
|
|
### `terminatingStatusCode`
|
|
|
|
_Optional, Default=503_
|
|
|
|
During the period in which Traefik is gracefully shutting down, the ping handler
|
|
returns a `503` status code by default.
|
|
If Traefik is behind, for example a load-balancer
|
|
doing health checks (such as the Kubernetes LivenessProbe), another code might
|
|
be expected as the signal for graceful termination.
|
|
In that case, the terminatingStatusCode can be used to set the code returned by the ping
|
|
handler during termination.
|
|
|
|
```yaml tab="File (YAML)"
|
|
ping:
|
|
terminatingStatusCode: 204
|
|
```
|
|
|
|
```toml tab="File (TOML)"
|
|
[ping]
|
|
terminatingStatusCode = 204
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--ping.terminatingStatusCode=204
|
|
```
