Update:
I figured it out:
---
- hosts: localhost
tasks:
- name: get filename of latest mongo backup
shell: s3cmd ls s3://my_backup_bucket/production/ | awk
'NF{p=$4}END{print p}'
register: lmongo
- set_fact: last_mongo="{{lmongo.stdout}}"
- hosts: db
tasks:
- debug:
msg: "mongo: {{{hostvars['localhost']['last_mongo']}}}"
Is there a better way?
