Clearwater Docker Compose file

Created a new docker compose file which will support affinity and anti-affinity policies for a set of 2 clearwater services.

##Affinity Policy We wanted the two clearwater services- ralf and sprout to run on the same node. So we had to set the environment parameter for ralf to have "affinity==sprout" and vice a versa for sprout "affinity==ralf"

sprout:
    image: 10.27.128.8/nfv/clearwaterdocker_sprout
    networks:
      default:
        aliases:
          - scscf.sprout
          - icscf.sprout
    ports:
      - 22
    environment:
      - "affinity:container==~clearwater_ralf*"


ralf:
    image: 10.27.128.8/nfv/clearwaterdocker_ralf
    ports:
      - 22
    environment:
      - "affinity:container==~clearwater_sprout*"

##Anti-Affinity Policy We wanted bono and ellis to run on two different nodes. So we had to set the environment key for bono to have "affinity!=ellis" and vice a versa for ellis "affinity!=bono"

 bono:
    image: 10.27.128.8/nfv/clearwaterdocker_bono
    ports:
      - 22
      - "5062:5062"
    expose:
      - "3478"
      - "3478/udp"
      - "5060"
      - "5060/udp"
    environment:
      - "affinity:container!=~clearwater_ellis*"
      
ellis:
    image: 10.27.128.8/nfv/clearwaterdocker_ellis
    ports:
      - 22
      - "80:80"
    environment:
      - "affinity:container!=~clearwater_bono*"

####Note The image repository, "10.27.128.8/nfv" is the DTR repo that we have setup up locally and tagged it for each clearwater conatiner images(e.g clearwaterdocker_bono, clearwaterdocker_ellis etc)
