I want to set up nginx HA with keepalived and I’m preparing an ansible role for this purpose in an openstack environment (I’m using ansible 2). I would like to update the server port, that is already existing, to add allowed\_address\_pairs with a single pair (the virtual IP and the host mac address).  
I have two problems:

- How to get the port\_id (to update the port with os\_port). I cannot get this id in any facts.
- How to get the information of that port in order to update only the allowed\_address\_pairs.

I know how to implement it in shell but it would be nice to use only ansible commands. Any hint how to achieve it?

Thanks in advance.

If you are using Ansible 2.1 you should be able to use the os\_port\_facts module.

Once you have the id of the port, you can use the os\_port module to update the allowed\_address\_pairs, for example:

- name: Update the allowed\_address\_pairs for the original port

local\_action:

module: os\_port

name: “{{ original\_port\_id }}”

state: present

allowed\_address\_pairs:

- ip\_address: “{{ ansible\_default\_ipv4.address }}”

- ip\_address: “{{ load\_balancer\_port.port.fixed\_ips[0].ip\_address }}”
