  1. Build docker image

  2. Start Redis (if not started) or start RabbitMQ (see 3)

    Instructions for installing starting and testing REDIS

    Install celery redis python client) $ pip install -U "celery[redis]"

     Change the linein tasks.py to use correct broker (REDIS or rabbitmq)
 #app = Celery('tasks', broker='pyamqp://guest@localhost//')  #rabbitmq
 app = Celery('tasks', broker='redis://localhost:6379/0')   #redis

    First attempt with redis failed it was necessary to re-install correct version of redis client pip install redis==2.10.6

     [celery redis issue solution](https://github.com/celery/celery/issues/5175)

    sudo service redis-server start sudo service redis-server stop sudo service redis-server status

  3. Start RabbitMQ

    stop the local node

    sudo service rabbitmq-server stop

    start it back

    sudo service rabbitmq-server start

    check on service status as observed by service manager

    sudo service rabbitmq-server status
