Ansible: copy file depending on hostname or role

  • 772

What's the best way to copy over a file depending on a hostname?

I need to copy over files with different content but with the same filename to several machines.

I have several files:

file.role1
file.role2
file.role3

Depending on hostname and/or role, I'd like like to copy file.roleX and rename it to file

Thanks.

    There are many ways to do this. Simplest:

    - name: Copy file.role1 to host1
  copy: src=file.role1 dest=/somewhere/file
  when: inventory_hostname == "host1"
- name: Copy file.role2 to host2
  copy: src=file.role2 dest=/somewhere/file
  when: inventory_hostname == "host2"

    Alternative, more compact:

    - name: Copy file to host
  copy: src=file.{{ inventory_hostname }} dest=/somewhere/file

    Or, using a template:

    - name: Copy file to host
  template: src=file dest=/somewhere/file

    where the template can be something like this:

    {% if inventory_hostname == "host1" %}
{% include "file1" %}
{% endif %}
...

    If you want different files in different roles, why don't you simply put this:

    - name: Copy file.role1 to file
  copy: src=file.role1 dest=/somewhere/file

    in each role's code?

    There is no preferred way to do it - it depends on what you are actually trying to accomplish.
