## Production advice

### Resource limitations

The examples shown deliberately do not specify any [resource limitations](https://kubernetes.io/docs/concepts/configuration/manage-compute-resources-container/) as there is no one size fits all.

In a production environment, however, it is important to set proper bounds, especially with regards to CPU:

- too strict and Traefik will be throttled while serving requests (as Kubernetes imposes hard quotas)
- too loose and Traefik may waste resources not available for other containers

When in doubt, you should measure your resource needs, and adjust requests and limits accordingly.
