Re: [ansible-project] loading tasks file based on ansible_fqdn value
Rule of thumb: If you find you have to edit your task: sections / files to add, remove, or rename hosts, you're doing it wrong.

Re: [ansible-project] loading tasks file based on ansible_fqdn value
This indicates that your inventory_hostname and your ansible_fqdn are
not the same, which can certainly be the case.
But Vladimir Botka is correct, and so is your intuition, that you should
have all these variables in the same place. However, that place
shouldn't be in your tasks:.

the second option seems too complex for my current scenario. I am
trying to gather all variables into a singe place. And having to
create a host_vars/.yml file for each host on each execution
contradicts that a bit too much.

This let's you expresses facts about hosts as data rather than as
results of expressions in set_fact or other tasks, task which you no
longer need to run.

First of all, throw out the second, because the strings that are

context, so the mustaches shouldn't be there.
In the first option, on this line:
when: ansible_fqdn == VM-0213.step.zrz.internal
the "ansible_fqdn" part is okay, but the expression on the
right-hand side "==" should be a string. Instead it's the value of
the variable "VM" minus the octal number 0213's missing attribute
"step"'s missing attribute "zrz"'s missing attribute "internal".
So, yeah, no wonder that doesn't work.
Try this instead:
when: ansible_fqdn == "VM-0213.step.zrz.internal"
and let us know how you get on.

Make your live easier and put the logic into the *vars*. For example,
shell> cat group_vars/all/level.yml
level_dict:
VM-0311.step.zrz.internal: passkey
VM-0312.step.zrz.internal: keycloak
VM-0313.step.zrz.internal: falsekey
level: "{{ level_dict[ansible_fqdn] }}"
Given the inventory for testing
shell> cat hosts
host1 ansible_fqdn=VM-0311.step.zrz.internal
host2 ansible_fqdn=VM-0312.step.zrz.internal
host3 ansible_fqdn=VM-0313.step.zrz.internal
use *set_fact" if you want to 'instantiate' the variable (put the
variable into the *hostvars*). You can omit *set_fact* if you don't
need hostvars.*.level. For example, the play
- hosts: all
tasks:
- set_fact:
level: "{{ level }}"
- debug:
var: level
gives (abridged)
ok: [host1] =>
level: passkey
ok: [host2] =>
level: keycloak
ok: [shot3] =>
level: falsekey
As a result, the code is cleaner. Also the concentration of data into
a single point of failure (a dictionary and assignment isolated in
*vars*) makes the code more robust.
