I would suggest approching it like this, though I haven't tested this and
I'm not very experienced with docker. (If anyone has experience with this
or knows a better solution please correct me :-) ):
1. Put your items in a separate file and define them as a dictionary.
Like this:
---
myservices:
- { name: "service1", ports: "8080:8080" }
- { name: "service2", ports: "8081:8080" }
- { name: "service3", ports: "8082:8080" }
2. Now in your playbook be sure to set serial: 1, include the yml file with
your service dict and define your tasks like this
---
- name: Start and wait for containers
docker: name=mydata image={{ item.name }} state=present ports={{ item.ports
}}
wait_for: port={{ item.wait_for_port }}
with_items:
- "{{myservices}}"
