Note

: This command is deprecated. Use the up 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, you can specify replicas under the deploy key as part of a service configuration for Swarm mode. 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.
