> **This command is deprecated.** Use the [up](up.md) command with the
|
|
`--scale` flag instead. Beware that using `up` with the `--scale` flag has
|
|
some [subtle differences](https://github.com/docker/compose/issues/5251) with
|
|
the `scale` command, as it incorporates the behaviour of the `up` command.

{: .warning }

```none
|
|
Usage: scale [options] [SERVICE=NUM...]
|
|
|
|
Options:
|
|
-t, --timeout TIMEOUT Specify a shutdown timeout in seconds.
|
|
(default: 10)
|

```

|
|
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-file/index.md), you can specify
|
|
[replicas](../compose-file/index.md#replicas)
|
|
under the [deploy](../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`.
