docker-compose scale
Estimated reading time: 1 minuteNote: This command is deprecated. Use the up command with the
--scale
flag instead. Beware that usingup
with--scale
flag has some subtle differences with thescale
command as it incorporates the behaviour ofup
command.
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, you can specify replicas under the deploy key as part of a service configuration for Swarm mode. The
deploy
key and its sub-options (includingreplicas
) only works with thedocker stack deploy
command, notdocker-compose up
ordocker-compose run
.
