I need to do something like this in a role, and I use an endpoint for some
of the items in the hash I feed it
shell: dosomething.sh {{ item.endpoint }}
when: "{{ item.endpoint }} is defined"
with_items: {{ myhash }}
myhash:
- { version: '{{ cqrs_version }}' }
- { version: '{{ staging_version }}', endpoint:
'http://localhost:8080/staging' }
It breaks as follows:
TASK: [gavdeploy | wait for endpoints to become available]
