Scaling the Docker Container

You can scale your Docker containers with Docker-Compose.

Start the Docker containers without specifying the port. In case you specify the port, then you are not able to scale the Docker container using the Docker-Compose's scale command. Docker compose's scale command provides flexibility to start desired containers with the same configuration by just specifying a number. So when you are scaling the Docker container, you are letting the Docker daemon assign a free port for the container you are starting.
Note: When scaling any service, it is mandatory to Run the OMS Server Container on a Predefined Port.

Procedure

  1. Change PWD to $OM_HOME/docker.
  2. Use the following command to scale the Order Management Server container and start, for example, three instances of the Order Management Server: 
    $] docker-compose --file docker-compose-run-oms.yml scale tibco-fom-oms=3
    In the above command, you have specified the service name tibco-fom-oms defined in docker-compose-run-oms.yml and are scaling it three times. In a similar way, you can scale the service for Automated Order Plan Development.
  3. After scaling the Docker container, check the container details by executing the following command: 
    $] docker ps -a
