I have another playbook that sets up a docker container, and now I want to add to the hosts file. Why does this not work?

- name: Add host entry  
docker\_container:  
name: “{{ item }}”  
etc\_hosts: “{‘[server.place.com](http://server.place.com)’: ‘{{ server\_ip }}’}”  
with\_items:
- “container1”
- “container2”

TASK [awx : Add host entry] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

failed: [123.123.123.123] (item= container1) =\> {“changed”: false, “item”: “container1”, “msg”: “Error creating container: 400 Client Error: Bad Request ("No command specified")”}

failed: [123.123.123.123] (item= container2) =\> {“changed”: false, “item”: “container2”, “msg”: “Error creating container: 400 Client Error: Bad Request ("No command specified")”}

If this is a bug, I’m happy to submit a report. I just wanted to make sure I wasn’t doing something wrong.
