Question:
As the subject says. I have some host variables defined in my hosts inventory file. How do I access them in my playbook?
Here is an example. Based on all my research I was expecting foo and bar to be part of hostvars. I can put host specific variables in separate var files, but I would love to keep them in my inventory file “attached” to a host. I don’t want to use it in templates.
ansible version: 1.3.2, ansible_distribution_version: 6.4

Answer:
Doing the following should work:
debug: msg="foo={{foo}}"
The foo variable will be evaluated in the context of the current host. Tested locally with ansible 1.3.4.
