Below are the available options for the health check mechanism:
- `path` is appended to the server URL to set the health check endpoint.
- `scheme`, if defined, will replace the server URL `scheme` for the health check endpoint
- `hostname`, if defined, will apply `Host` header `hostname` to the health check request.
- `port`, if defined, will replace the server URL `port` for the health check endpoint.
- `interval` defines the frequency of the health check calls.
- `timeout` defines the maximum duration Traefik will wait for a health check request before considering the server failed (unhealthy).
- `headers` defines custom headers to be sent to the health check endpoint.
- `followRedirects` defines whether redirects should be followed during the health check calls (default: true).
- `path` (required), defines the server URL path for the health check endpoint .
- `scheme` (optional), replaces the server URL `scheme` for the health check endpoint.
- `hostname` (optional), sets the value of `hostname` in the `Host` header of the health check request.
- `port` (optional), replaces the server URL `port` for the health check endpoint.
- `interval` (default: 30s), defines the frequency of the health check calls.
- `timeout` (default: 5s), defines the maximum duration Traefik will wait for a health check request before considering the server unhealthy.
- `headers` (optional), defines custom headers to be sent to the health check endpoint.
- `followRedirects` (default: true), defines whether redirects should be followed during the health check calls.
