It looks like with_subelements is what I wanted:
- name: run deployment tasks
shell: >
cd ~/www/projects/{{ item.0.name }} && {{ item.1.cmd }}
with_subelements:
- big_var_collection
- deployment_tasks
I added a 'name' property to the hash (which was the same as the key) to
make this work:
big_var_collection:
application_1:
name: application_1
deployment_tasks:
- { cmd: 'bundle exec rake thing:1', metadata: 'yay' }
- { cmd: 'bundle exec rake thing:2', metadata: 'boo' }
application_2:
name: application_2
deployment_tasks:
- { cmd: 'bundle exec rake thing:3', metadata: 'yay' }
- { cmd: 'bundle exec rake thing:4', metadata: 'boo' }
