### Add Garage service
To add Garage on Traefik you should declare a new service using its IP address (or hostname) and port:
To add Garage on Traefik you should declare two new services using its IP
address (or hostname) and port, these are used for the S3, and web components
of Garage:
```toml
[http.services]
[http.services.my_garage_service.loadBalancer]
[[http.services.my_garage_service.loadBalancer.servers]]
[http.services.garage-s3-service.loadBalancer]
[[http.services.garage-s3-service.loadBalancer.servers]]
url = "http://xxx.xxx.xxx.xxx"
port = 3900
[http.services.garage-web-service.loadBalancer]
[[http.services.garage-web-service.loadBalancer.servers]]
url = "http://xxx.xxx.xxx.xxx"
port = 3902
```
It's possible to declare multiple Garage servers as back-ends:
```toml
[http.services]
[[http.services.my_garage_service.loadBalancer.servers]]
[[http.services.garage-s3-service.loadBalancer.servers]]
url = "http://xxx.xxx.xxx.xxx"
port = 3900
[[http.services.my_garage_service.loadBalancer.servers]]
[[http.services.garage-s3-service.loadBalancer.servers]]
url = "http://yyy.yyy.yyy.yyy"
port = 3900
[[http.services.my_garage_service.loadBalancer.servers]]
[[http.services.garage-s3-service.loadBalancer.servers]]
url = "http://zzz.zzz.zzz.zzz"
port = 3900
[[http.services.garage-web-service.loadBalancer.servers]]
url = "http://xxx.xxx.xxx.xxx"
port = 3902
[[http.services.garage-web-service.loadBalancer.servers]]
url = "http://yyy.yyy.yyy.yyy"
port = 3902
[[http.services.garage-web-service.loadBalancer.servers]]
url = "http://zzz.zzz.zzz.zzz"
port = 3902
```
Traefik can remove unhealthy servers automatically with [a health check configuration](https://doc.traefik.io/traefik/routing/services/#health-check):
