## Usage
### Plugin configuration
```yml
testData:
serviceUrl: http://ondemand:10000
name: TRAEFIK_HACKATHON_whoami
timeout: 1m
```
| Parameter | Type | Example | Description |
| ------------ | --------------- | -------------------------- | ----------------------------------------------------------------------- |
| `serviceUrl` | `string` | `http://ondemand:10000` | The docker container name, or the swarm service name |
| `name` | `string` | `TRAEFIK_HACKATHON_whoami` | The container/service to be stopped (docker ps | docker service ls) |
| `timeout` | `time.Duration` | `1m30s` | The duration after which the container/service will be scaled down to 0 |
### Traefik-Ondemand-Service
The [traefik-ondemand-service](https://github.com/acouvreur/traefik-ondemand-service) must be used to bypass [Yaegi](https://github.com/traefik/yaegi) limitations.
Yaegi is the interpreter used by Traefik to load plugin and run them at runtime.
The docker library that interacts with the docker deamon uses `unsafe` which must be specified when instanciating Yaegi. Traefik doesn't, and probably never will by default.
