Ansible - Dynamicaly update /etc/hosts files on target servers
I was configuring GlusterFS on few servers using Ansible external link and have a need to update /etc/hosts with hostnames for easier configuration. I found this one working: - name: Update /etc/hosts lineinfile: dest=/etc/hosts regexp='.*{{item}}$' line='{{hostvars.{{item}}.ansible_default_ipv4.address}} {{item}}' state=present with_items: '{{groups.somegroup}}' Source: http://xmeblog.blogspot.com/2013/06/ansible-dynamicaly-update-etchosts.html external link
