Setting a dictionary variable dynamically

I’m struggling to find the best way to define a dictionary variable dynamically. My goal is to define a dictionary with product versions as keys and the latest revisions as values. That way I can define the path to the latest build for each product version.

It seems like a lookup plugin should be perfect, even though they’re required to return a list. I tried sending back the dictionary inside a list, but that fails with

“an unexpected type error occured. Error was sequence item 0: expected string, dict found”

I get this same error whether I use vars: or set_fact with complex arguments.

I then took a different approach and converted my lookup plugin to a module which defines a specific fact. This worked, but unfortunately the fact is scoped to each host, so the module has to run repeatedly. Is there a better way?

Sounds like you should just have a dictionary of values and use a variable to select an index into it, you don’t really want to define the dictionary dynamically but pick an element.

And how can I use a variable to select an index into a dictionary?

vars:
ind: ‘ind1’
dict:
ind1:
value: 1
ind2:
value: 2

I’d like to get something like {{ dict.{{ ind }} }} (which obviously fails …)
