Hi,
We have multiple clusters. Each of the clusters need to have a different
var file (cluster specific variables)
Currently the variable file name is same as the cluster name, so that when
the extra-variable says cluster=ABC, my playbook picks up the variable file
ABC.yml which I refer to in the playbook by {{cluster}}.yml.
This has a risk because the user while running the playbook might give the
inventory file name of cluster XYZ and give cluster=ABC.
In order to avoid this risk, I want to pick up my variable file
as {{inventory_file}}.yml
But looks like the variable file is referred to, before the
variable inventory_file is loaded?
Because even though {{inventory_file}}.yml is picked up correctly under
tasks(I printed it our using debug:) the variable file is not being picked
up.
Am I missing something here?
Thanks and regards,
Mridu
