No, I'm not referring to the inventory file, it will be a separate file that will have other hosts. However, you have pointed me in the right direction, thank you for that. Here is what I have come up with and this works, but my problem now is that every time there are new servers added, the existing servers will get the same hosts records all the time so there will be duplicates in the /etc/hosts. I haven't been able to figure out how to look at the existing servers in the host file and only add new servers.:
*--- # Copy hosts file* *- hosts: all* * become: yes* * tasks:* * - name: update hosts template file* * copy:* * src: /home/ansible/hostfile * * dest: /tmp/hostfile* * owner: root* * group: root* * mode: 0644* * backup: yes* * - name: Append template file to master host file* * shell: cat /tmp/hostfile >> /etc/hosts* * - name: Delete temp file* * file:* * path: /tmp/hostfile* * state: absent* This works, but my problem now is that every time there are new servers added, the existing servers will get the same hosts records all the time so there will be duplicates in the /etc/hosts. I haven't been able to figure out how to look at the existing servers in the host file and only add new servers. On Sunday, April 28, 2019 at 5:53:36 AM UTC-4, Kunalsing Thakur wrote: > > Yes.
