The value of groups_tree_var = 5000.
This comes from host, not the parents or grandparents.
The value of the grandparent variable grandparent_var is
not overridden and is = 2000
The value of the parent variable is not overridden and
is = 6000
The variable 'overridden_in_parent' is set in the parent
and grandparent, so the parent wins. It's value is = 1000.
The values of 'uno', 'dos', and 'tres' are set in group_vars/all but 'tres' is
set to the value of 'three' in group_vars/local, which should override it.
uno = 1
dos = 2
tres = three
The values of 'a', 'b', 'c', and 'd' are set in host_vars/local and should not
be clobbered by values that are also set in group_vars.
a = 1
b = 2
c = 3
d = 4
The value of 'badwolf' is set via the include_vars plugin.
badwolf = badwolf
The value of 'winter' is set via the main.yml in the role.
winter = coming
Here's an arbitrary variable set as vars_files in the playbook.
vars_file_var = 321
And vars.
vars = 123
Variables about other hosts can be looked up via hostvars. This includes
facts but here we'll just access a variable defined in the groups.
999
Ansible has pretty basic precedence rules for variable overriding. We already have
some tests above about group order. Here are a few more.
* -e variables always win
* then comes "most everything else"
* then comes variables defined in inventory
* then "role defaults", which are the most "defaulty" and lose in priority to everything.
Given the above rules, here's a test that a -e variable overrides inventory,
and also defaults, and role vars.
etest = from -e
Now a test to make sure role variables can override inventory variables.
role_var_beats_inventory = chevron 5 encoded
Role variables should also beat defaults.
role_var_beats_default = chevron 6 encoded
But defaults are lower priority than inventory, so inventory should win.
inventory_beats_default = narf
That's the end of the precedence tests for now, but more are welcome.
