Replace a line in a config file with ansible

Question

I am new to ansible.

Is there a simple way to replace the line starting with option domain-name-servers in /etc/dhcp/interface-br0.conf with mo

Answer 1

I created a role dhcp with the following main.yaml:

---
- name: add all dns servers
  lineinfile:
    dest: /etc/dhcp/interface-br0.conf
    regexp: '^\s*option domain-name-servers.*$'
    line: '  option domain-name-servers 10.116.184.1,10.116.144.1,10.116.136.1;'
    backrefs: yes
  become: true
