"""Takes results (`hostvars`) from the openshift_cert_expiry role
check and serializes them into proper machine-readable JSON
output. This filter parameter **MUST** be the playbook `hostvars`
variable. The `play_hosts` parameter is so we know what to loop over
when we're extrating the values.
Returns:
Results are collected into two top-level keys under the `json_results`
dict:
* `json_results.data` [dict] - Each individual host check result, keys are hostnames
* `json_results.summary` [dict] - Summary of number of `warning` and `expired`
certificates
Example playbook usage:
- name: Generate expiration results JSON
run_once: yes
delegate_to: localhost
when: openshift_certificate_expiry_save_json_results|bool
copy:
content: "{{ hostvars|oo_cert_expiry_results_to_json() }}"
