Here's how I used Michael's kind advice:
- name: bring up container for {{ new_hostname }} from {{ image_name }}
docker: >
dns=8.8.8.8
hostname={{ new_hostname }}
image="{{ image_name }}"
state=present
name="{{ new_hostname }}"
expose=22
{{ docker_ports }}
- name: add {{ new_hostname }} to inventory
add_host: name={{ new_hostname }}
groups=docker
ansible_ssh_host={{ item.NetworkSettings.IPAddress }}
ansible_ssh_port=22
when: item.Config.Hostname == "{{ new_hostname }}" and item.State.Running
== True
with_items: docker_containers
- name: "wait for {{ new_hostname }}'s sshd to come up"
wait_for: host={{ new_hostname }} port=22 state=started
