Does foreman store facts as hash?
Because when i queried the node using api to gather facts, i see that the
facts hash that i uploaded is now null:
"kickstart_repos": null,
"kickstart_repos::base": null,
I see that it has created the child variables out of the hash.
"kickstart_repos::base::baseurl":
"http://10.230.1.106:8090/centos/7/os/x86_64/";,
This makes the template writing really difficult, because i will have to
statically mention each key of the facts hash that i have uploaded, in the
templates.
One of the advantages of hash is that it could be dynamic, and we should be
able to iterate over whichever keys it contains.
How do i make foreman store the facts as a hash and not function as above?
