> **Note**: This command is deprecated. Use the [up](up.md) command with the
|
|
`--scale` flag instead.
|
|
|
|
```
|
|
Usage: scale [SERVICE=NUM...]
|
|
```
|
|
|
|
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 the [deploy](/compose/compose-file/index.md#deploy) key as part of a
|
|
service configuration for [Swarm mode](/engine/swarm/). The `deploy` key and its sub-options (including `replicas`) only works with the `docker stack deploy` command, not `docker compose up` or `docker-compose run`.
