Hello,
Can someone please help to solve my request?
with blockinfile module, I'm looking for option to check the entries
whether its present or not! if not then entries have to be added by play.
As per below my playbook, its working partially, like its appending even if
the entries are already present but actually i'm looking that play should
ignore if already entries are exists and incase not present then it should
added.
*Playbook:-*
cat resolv_add.yml
---
- hosts: resolv
become: yes
tasks:
- name: check the presence of lines
shell: cat /tmp/resolv.conf |egrep "Hello the world|i'm here|is it
working"
register: result
ignore_errors: yes
- debug: msg="{{result.stdout}}"
- name: add lines below lines if not exists
blockinfile:
marker: ""
block: |
Hello the world
i'm here
is it working
path: /tmp/resolv.conf
state: present
changed_when: result.stdout.find('exists') == -1
*Execution Output:-*
ansible-playbook resolv_add.yml
SUDO password:
PLAY [resolv]
