Reading partial string

Hi,

I have a simple playbook that takes an IP address from the input file and update this IP including hostname under /etc/hosts.

The problem is that in the input file the IP is written with subnet – 1.1.1.1/24

While I need only the IP 1.1.1.1

Playbook :

  • hosts: localhost

become: true

any_errors_fatal: true

gather_facts: False

vars_files:

  • /opt/ input-file.yml

tasks:

  • name: Update server etc/host with response ip

lineinfile:

path: /etc/hosts

line: “{{ lb_ext_ip }} hdfs”

state: present

backup: yes

Result in /etc/hosts

1.1.1.1/24 hdfs

Required results:

1.1.1.1 hdfs

Use the ipaddr filter:

{{ lb_ext_ip | ipaddr('address') }}
