Re: [ansible-project] Determining the primary IP address
Ok.. so some more info... I think I have a workable solution. I"ll be
testing it tomorrow, but I am 99% sure I have it figured out. The code
above, actually didn't work as I thought.. so, I changed this:
when: hostvars[inventory_hostname]['ansible_default_ipv4']['address'] |
select('match', '^10.[0-9]+')
to this:
when: hostvars[inventory_hostname]['ansible_default_ipv4']['address'] |
regex_search('^10.[0-9]+')
That seems to have gotten me the result I was looking for.
As for the "default ipv4" not being consistent, I went back and re-read the
article. Basically, the author said that if you don't set a default route,
then the default.ipv4.address will be empty. I decided this was not a huge
deal, since I can't think of a situation where I have installed a server
without a default route. :)
So anyway, thanks again for the help, I do appreciate it.

Re: [ansible-project] Determining the primary IP address
I hadn't heard about any inconsistencies either, which is why I figured I'd
ask here. I thought about the ipaddr filter, but you need to install a
python module for it to work. (netaddr I think) and I was just trying to
figure it out using the base set of modules, etc. Thanks for the info
though, I appreciate it

Re: [ansible-project] Determining the primary IP address
I don't know about any such unreliability.
As for determining if the address is in a specific prefix, I would
definitely use the ipaddr filter:

[ansible-project] Determining the primary IP address
Good afternoon.
I have this snippet of code, that sets a proxy variable if the default
ipv4 IP address is in 10 net space. I had read somewhere that using the
ansible_default_ipv4 fact, wasn't always reliable. So is there a better
way to grab the primary IP other than what I did below?
- name: PreTask | Configure proxy
set_fact:
_zabbix_proxy: "{{zabbix_http_proxy}}"
when: hostvars[inventory_hostname]['ansible_default_ipv4']['address'] |
select('match', '^10.[0-9]+')
Thanks for the help!!
