Ah, silly me. As is my wont, I overthought this. This works to do what I
want:
---
- hosts: myhost
gather_facts: False
become: yes
become_method: sudo
vars_files:
- zones.yml
vars:
old_serial: "2023010301"
next_serial: "{{ lookup('pipe', 'date +%Y%m%d') }}01"
year: "{{ lookup('pipe', 'date +%Y) }}"
tasks:
- name: Add TXT entry to zone file
lineinfile:
dest: "{{ item }}"
insertafter: EOF
line: '_some-name TXT
"aZBBBBhonRJiOCL1ZtkKMKnx7U2k3wbSswyClGb6wGk"'
with_items: "{{ zone_files }}"
- name: Update serial number
replace:
dest: "{{ item }}"
regexp: '{{ old_serial }}'
replace: '{{ next_serial }}
with_items: "{{ zone_files }}"
But, to make this even more automated, it would be good to auto-increment
the serial number's last two digits (e.g. 20231113*01* to 20231113*02 *on
every run of the playbook. Is that possible?
