COMPONENT NAME

{{ansible_fqdn}}

ANSIBLE VERSION

ansible 2.1.1.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = Default w/o overrides

CONFIGURATION

using certain ansible variables. Using this playbook https://github.com/jdauphant/ansible-role-ssl-certs

OS / ENVIRONMENT

SUMMARY

I'm trying to use the "{{ansible_fqdn}}" to name certain files with the hostname in a VM in openstack. Openstack has private/public IP/Hostname and it uses the private hostname to name the file. The playbook I'm using is https://github.com/jdauphant/ansible-role-ssl-certs/blob/master/defaults/main.yml. Looked around google to see how ansible finds this hostname and it said by using:

python -c "import socket; print socket.gethostname()"
python -c "import socket; print socket.gethostbyaddr('result from previous command')"

Is their a way to make ansible query DNS using the Public IP to get the Public name?

STEPS TO REPRODUCE

https://github.com/jdauphant/ansible-role-ssl-certs/blob/master/defaults/main.yml

EXPECTED RESULTS

To name the file using the Public hostname or the name that DNS has instead of the name of the VM when it was created. For example, DNS has this hostname as dude.hadoop.cloud.org but, instead it created the file with the name of the VM when it was created.

ACTUAL RESULTS

When you create a VM in openstack it asks for an instance name. A VM is created with $instance name and uses that as its private name. This is the name that ansible picks up. This is somewhat the same with AWS.

@chagara Is the public IP address listed in the "ip addr show" output? I don't think most cloud instances expose the public IP to the instance. I think you probably need to look at using the API to get the data you want, which is probably available via the open stack facts module: http://docs.ansible.com/ansible/os_server_facts_module.html

Please take a look into that and if you need further guidance, use the ansible project mailing list or the irc channel.
