#### max_replicas_per_node

If the service is `replicated` (which is the default), [limit the number of replicas](/engine/reference/commandline/service_create.md#specify-maximum-replicas-per-node---replicas-max-per-node)
that can run on an node at any time.

> **[Version 3.8](compose-versioning.md#version-3) and above.**

When there are more tasks requested than running nodes, an error `no suitable node (max replicas per node limit exceed)` is raised.

```yaml
version: "{{ site.compose_file_v3 }}"
services:
worker:
image: dockersamples/examplevotingapp_worker
networks:
- frontend
- backend
deploy:
mode: replicated
replicas: 6
max_replicas_per_node: 1
```
