In 1.8.0 version, If I didn’t pass “ports” variable, Docker module will not bind any port to the Docker Host. It worked correctly.  
However, In 1.9.0.1, Docker module choose a random ports, and bind to Docker Host. I think there is something wrong. Please correct me if I wrong.  
If I remove this line ( ports: “{{ docker\_ports|default(omit) }}” ) , the docker module works correctly.

```auto
- name: Run docker container
docker:
image: "{{ docker_image }}"
name: "{{ docker_name }}"
command: "{{ docker_command|default(omit) }}"
ports: "{{ docker_ports|default(omit) }}"
env: "{{ docker_env|default(omit) }}"
volumes: "{{ docker_volumes|default(omit) }}"

```
