When I enter the command
docker-compose up -d --scale web=5
The following is displayed
Builds, (re)creates, starts, and attaches to containers for a service. Unless they are already running, this command also starts any linked services. The `docker-compose up` command aggregates the output of each container. When the command exits, all containers are stopped. Running `docker-compose up -d` starts the containers in the background and leaves them running.
No service is scaled up.
The OS is openSUSE Leap.
The remainder of the output is
If there are existing containers for a service, and the service's configuration or image was changed after the container's creation, `docker-compose up` picks up the changes by stopping and recreating the containers (preserving mounted volumes). To prevent Compose from picking up changes, use the `--no-recreate` flag. If you want to force Compose to stop and recreate all containers, use the `--force-recreate` flag. Usage: up [options] [SERVICE . . . ] Options: -d Detached mode: Run containers in the background, print new container names. Incompatible with --abort-on-container-exit. --no-color Produce monochrome output. --no-deps Don't start linked services. --force-recreate Recreate containers even if their configuration and image haven't changed. Incompatible with --no-recreate. --no-recreate If containers already exist, don't recreate them. Incompatible with --force-recreate. --no-build Don't build an image, even if it's missing. --build Build images before starting containers. --abort-on-container-exit Stops all containers if any container was stopped. Incompatible with -d. -t, --timeout TIMEOUT Use this timeout in seconds for container shutdown when attached or when containers are already running. (default: 10) --remove-orphans Remove containers for services not defined in the Compose file
