Line too long for setting up variable - ansible

Question

This is my Ansible task:
- name: get the custom job id
ansible.builtin.set_fact:
custom_job_id: >
"{{ train_custom_image_unmanaged_response.stderr_lines |select('search', 'describe') |list |regex_search('.*/customJobs/(\\d+)', '\\1') |first }}"
when: "(gcs_model_list.stdout is not defined) or ('saved_model.pb' not in gcs_model_list.stdout)"
I am getting "line too long" as Ansible lint error for custom_job_id line.
Any idea how can I break it down in smaller parts?

Answer 1

You can do it using YAML multi lines syntaxes, as you started doing it.
With this syntax, the indentation is what is defining a block, so, as long as you are indented inward of the fact name custom_job_id, all the following code is considered as being the expression that is going to be assigned to that fact.
For example:
- name: get the custom job id
ansible.builtin.set_fact:
custom_job_id: >-
{{
train_custom_image_unmanaged_response.stderr_lines
| select('search', 'describe')
| list
| regex_search('.*/customJobs/(\d+)', '\1')
| first
}}
when: >-
gcs_model_list.stdout is not defined
or 'saved_model.pb' not in gcs_model_list.stdout
Here is a playbook complying with the Ansible linting demonstrating this:
- hosts: localhost
gather_facts: true
tasks:
- name: Get the custom job id
ansible.builtin.set_fact:
custom_job_id: >-
{{
train_custom_image_unmanaged_response.stderr_lines
| select('search', 'describe')
| list
| regex_search('.*/customJobs/(\d+)', '\1')
| first
}}
when: >-
gcs_model_list.stdout is not defined
or 'saved_model.pb' not in gcs_model_list.stdout
vars:
train_custom_image_unmanaged_response:
stderr_lines:
- foo
- bar
- describe - /customJobs/123
- baz
gcs_model_list:
- name: Display `custom_job_id`
ansible.builtin.debug:
var: custom_job_id
Which yields:
PLAY [localhost] **********************************************************
TASK [Get the custom job id] **********************************************
ok: [localhost]
TASK [Display `custom_job_id`] ********************************************
ok: [localhost] =>
custom_job_id: '123'
