i got it to work the simple way with multiple tasks
---
- name: test
hosts: k8s
tasks:
- name: comment line
lineinfile:
line: "#image: graylog/graylog4.2.5"
regexp: '^image:\sgraylog/graylog4.2.5'
path: /tmp/temp2.txt
- name: add line
lineinfile:
line: "image: graylog/graylog4.2.8"
path: /tmp/temp2.txt
create: true
probably not the most efficient.
