Your entire playbook could look like this:
---
- name: "Eliminamos dnsmasq y agregamos dns del endpoint de route53"
hosts: servers
vars:
package_names:
- dnsmasq
become: yes
gather_facts: no
tasks:
- name: "Borramos el paquete"
package:
name: "{{ package_names }}"
state: absent
- name: "Agregamos IPs de los nuevos DNS de route53"
lineinfile:
path: /etc/resolv.conf
backup: yes
state: present
line: "{{ item }}"
with_items:
- 'nameserver 10.54.130.237'
- 'nameserver 10.54.131.106'
- 'nameserver 169.254.169.253'
- name: "Comentamos el primer nameserver ya que no usamos mas"
shell:
cmd: |
sed -i '/nameserver/s/.*/#&/;:A;n;bA' /etc/resolv.conf
One addition note is that the last task appears to comment out every "
nameserver" line in /etc/resolv.conf including the ones you added in the
prior task. Is that what you intend?
