What are some advanced commands in Docker Compose?
Docker Compose has several advanced commands like docker-compose up --scale
, docker-compose logs
, and docker-compose exec
. Would you like to know more about any specific command?
Can you explain the --scale
option?
Sure! The --scale
option allows you to specify the number of containers to run for a particular service. For example, docker-compose up --scale web=3
will start three instances of the 'web' service.

command?
The docker-compose logs
command shows the logs for all services defined in your docker-compose.yml
