```
|
|
|
|
Sets the number of containers to run for a service.
|
|
|
|
Numbers are specified as arguments in the form `service=num`. For example:
|
|
|
|
docker-compose scale web=2 worker=3
|
|
|
|
>**Tip:** Alternatively, in
|
|
[Compose file version 3.x](/compose/compose-file/index.md), you can specify
|
|
[`replicas`](/compose/compose-file/index.md#replicas)
|
|
under [`deploy`](/compose/compose-file/index.md#deploy) as part of the
|
|
service configuration for [Swarm mode](/engine/swarm/).
