update /etc/hosts file

[Diego Rucci]

Hi, I'm just starting with ansible.
I'm running a proxmox server with 12 containers.
I made some playbooks that actually works (like setting tzdata and apt-update)

I was trying to automate etc/hosts file update. I'm using this playbook, taken from here:

---
- hosts: wordpress
  gather_facts: True
  tasks:
  - name: update hosts
    lineinfile: dest=/etc/hosts1 regexp='.*{{ item }}$' line="{{ hostvars[item].
ansible_default_ipv4.address }} {{item}}.mydomain {{item}} " state=present
    when: hostvars[item].ansible_default_ipv4.address is defined
    with_items: groups['all']

Note I'm using etc/hosts1 file and just 1 host for testing! When I get running will change to correct values.

This works, but duplicate lines every time I run playbook, like this:
192.168.0.30 wordpress.mydomain wordpress
192.168.0.30 wordpress.mydomain wordpress
192.168.0.30 wordpress.mydomain wordpress

Is there something I'm missing?
Thanks

Found it.
It is an extra "space" at lineinfile:

..... {{item}} " state=present

should it be

..... {{item}}" state=present
