Ansible - use host IP as a variable for file copies

  • 772

I am looking for a way for config management with Ansible.

I have the structure repo/1.2.3.4/file.conf.

Can Ansible get the IP 1.2.3.4 per host and deploy the file to the host? Using a variable would make the config easier.

- copy: src=/repo/$IP/file.conf dest=/etc/file.conf owner=foo group=foo mode=0644

    Yes, you can do that with Ansible. Ansible geathers facts of the system before every run. You can check these facts about the system with the setup module like this:

    ansible hostname -m setup

    Check the documentation for more information.

    You are looking for the default ip4 address I assume. Which would be ansible_default_ipv4. You can access the value of the variable like this:

    - copy: src=/repo/{{ ansible_default_ipv4.address }}/file.conf dest=/etc/file.conf owner=foo group=foo mode=0644
