Usage of Ansible Inventory in local provisioning

[dav-pascual]

The support of ansible inventory in local provisioning could be problematic and introduce potential security issues e.g. you can run tasks on localhost even on the multi-host system

Investigate:

• If supporting inventory in local provisioning would bring any benefit
• If its support could introduce security issues

Needs more discussion to find out what to do here.

From the hacking session:

• Running ansible and having inventory for local provision makes sense because you could have multiple local provision guests
• Prohibiting local/localhost on all other provision types makes sense, but requires research on how to do it. If you have ideas, let us know
