Rancher Collabora

Hi I am having trouble getting Collabora to run properly on Rancher. I have next cloud working A OK but cannot get Collabora to work. I am using Rancher 1.6 and its native load balancer (which is haproxy).

Any recommendations?

here is my compose in rancher:

version: '2'
services:
  nextcloud:
    image: nextcloud
    stdin_open: true
    volumes:
    - /mnt/zpool1/Apps/Nextcloud/nextcloud:/var/www/html
    tty: true
    links:
    - mysql:mysql
    ports:
    - 8081:80/tcp
    labels:
      io.rancher.container.pull_image: always
  mysql:
    image: mysql
    environment:
      MYSQL_DATABASE: nextcloud
      MYSQL_PASSWORD: <password>
      MYSQL_ROOT_PASSWORD: <password>
      MYSQL_USER: nextcloud
    stdin_open: true
    volumes:
    - /mnt/zpool1/Apps/Nextcloud/mysql:/var/lib/mysql
    tty: true
    labels:
      io.rancher.container.pull_image: always
  collabora:
    cap_add:
    - MKNOD
    image: collabora/code
    environment:
      domain: nextcloud.example.com
      username: admin
      password: <password>
      server_name: collabora.example.com
    stdin_open: true
    tty: true
    ports:
    - 9980:9980/tcp
    labels:
      io.rancher.container.pull_image: always
