Split debug variable output into two separate variables in ansible - ansible

Question

I am using below code snippet where image details would be printed:
- set_fact:
image_name: "{{ load.results|map(attribute='stdout_lines')|list }}"
- debug:
var: image_name
Output:
TASK [set_fact] ***************************************************************************************************************************************************************************
ok: [xx.xx.xx.xx]
TASK [debug] ******************************************************************************************************************************************************************************
ok: [xx.xx.xx.xx] => {
"image_name": [
[
"Loaded image(s): localhost/cim:v1.5"
],
[
"Loaded image(s): localhost/cim:v1.8"
]
]
}
Is there a way I can store the image name and tag in two separate variables under set_fact itself or in any other form so I can reuse those 2 variables for the next task?

Answer 1

You can use a regex_findall filter in order to achieve this.
The regex used here is (\S*):(\S+). if needed, more explanation on it can be found here
Given the playbook:
- hosts: all
gather_facts: no
vars:
load:
results:
- stdout_lines:
- "Loaded image(s): localhost/cim:v1.5"
- stdout_lines:
- "Loaded image(s): localhost/cim:v1.8"
tasks:
- set_fact:
images: "{{ images | default([]) + item | regex_findall('(\\S*):(\\S+)') }}"
loop: "{{ load.results | map(attribute='stdout_lines') | flatten }}"
- debug:
msg: "This image repository is `{{ item.0 }}` and its tag is `{{ item.1 }}`"
loop: "{{ images }}"
This yields the recap:
PLAY [all] *********************************************************************************************************
TASK [set_fact] ****************************************************************************************************
ok: [localhost] => (item=Loaded image(s): localhost/cim:v1.5)
ok: [localhost] => (item=Loaded image(s): localhost/cim:v1.8)
TASK [debug] *******************************************************************************************************
ok: [localhost] => (item=['localhost/cim', 'v1.5']) => {
"msg": "This image repository is `localhost/cim` and its tag is `v1.5`"
}
ok: [localhost] => (item=['localhost/cim', 'v1.8']) => {
"msg": "This image repository is `localhost/cim` and its tag is `v1.8`"
}
