Merging inventories?

Archives Ansible Project

Hi,

When one has multiple inventories like:

inventories/a/hosts
inventories/b/hosts
inventories/…

Is there an easy way to run a task or playbook against all of them without explicitly having to define each inventory on the command-line?

The use case here is that all those groups contain machines for different departments or even sub-companies, however they all share certain SSL-certificates that I would like to be able to deploy to all hosts at once.

Thanks,
Nico.

We normally just wrap it in a shell loop:

for i in inventories/*/hosts
  do
    ansible-playbook -i $i foo.yml
  done

We wrote a way to merge static and dynamic inventories; you could also use
it to have static inventories in multiple files, and merge them together.

Try to use:

ansible-playbook -i inventories

because Ansible can use directories.

You also can use symlinks for more complicated cases.
