Hii
I have a list of dicts, where I want to inject a number of helper keys.
I can do this with set_facts in a loop. Example playbook (hopefully this
displays OK):
---
- name: Add helper keys to list of dicts
hosts: localhost
connection: local
gather_facts: no
tasks:
- set_fact:
backup_objects: "{{ backup_objects|default([]) | union(
[
item | combine(
{
'basename': item.Key|regex_replace('^' ~ prefix ~
'\\d{10}_(.*)\\.pgdump', '\\1')
}
)
]
)
}}"
loop: "{{ all_objects }}"
loop_control:
label: "{{ item.Key }}"
- debug: var=backup_objects
vars:
prefix: backup/database/
all_objects:
- ETag: '"d41d8cd98f00b204e9800998ecf8427e"'

This works, but in my real world use case this list is very long, so there
will be a lot of output because of each iteration. I have already set the
loop label to something less noisy.
Is there a way to add keys to a list of dicts, where those new keys are
based on an operation of another key?
thx !
Dick
