Hi Team I have a playbook i run in several different situations, in each case with a different inventory file. The inventory files use FQDNs. In each case i have to edit /etc/resolv.conf to change the dns resolver before running it. I know i could hardcode IP addresses within inventory files or set up a local nameserver with a bunch of forwarder records, but before i do something like that, a question … Is there a way to change the DNS resolver on a per playbook basis, or from the commandline? Thanks ChIP ---

There is no portable way of doing so on Unix/Linux, and while you might be able to invent a method which uses `LD_LIBRARY_PATH` to circumvent the current resolver library and thus its configuration, I wouldn’t go down that route. What I would do in this case, and I know you said you’d prefer to avoid it, is use `ansible_host=` in inventory or `group_vars`/`host_vars`, etc. Alternatively you might be able to set up your own resolver which permits you to reconfigure hosts on the fly, but it’s a lot of work and won’t reduce the number of moving bits. ---

Your playbooks and inventory contains FQDN, you write. Would you be able to _generate_ the inventory with the specific IP addresses on the fly? Be it either a statically created inventory or a dynamic inventory? Just a thought … ---

This sounds like DNS is not set up right on your Ansible controller. What specifically are you changing in /etc/resolv.conf that makes it work? ---

Thanks for the suggestion. DNS is fine. Im changing ‘nameserver’ clause in resolv.conf to point to the ‘correct’ resolver for each client.
