Hi,
In a Jijna2 template I need a following variable from hostvars.
hostvars['{{project}}-example.com'].ansible_eth0.ipv4.address
As you can see part of the hostname is dynamical created based
external variable. I don't think such operation is possible. However,
I wonder if there is any way to access such a variable.
Thanks,

Have you tried that? We used to use hostvars a lot* and I'm sure I'd
have done something like
this previously.
* (we got rid of them in the end because if 'project'-example.com was
down, ansible couldn't run
on any other boxes. In the end we to solve your sort of problem we
just added DNS entries for
those IPs and set vars explicitly in the plays)

hostvars['{{project}}-example.com'].ansible_eth0.ipv4.address
I'm pretty sure something like
hostvars[project + '-example.com'].ansible_eth0.ipv4.address
will work. You might need to bracket-ify the whole thing, like
hostvars[project + '-example.com']['ansible_eth0']['ipv4']['address']
Not sure about that, I don't have a good sense of when Jinja lets you use
dots to mean keys in a dict, and when it doesn't. And how it knows which
are variables and which are literals. Anyway, something like that.

Seems to work.
