More dynamic variables

[Mark Tovey]

    I hate having to constantly go here to solve issues like this, especially when the issues I keep presenting are all so similar, but eventually I have to just give up trying to solve this on my own and ask.

    I want to define a structure in a vars file that looks like the following:

myos: {

    configdir: "/path/to/directory",

    configfile: "filename"

} 

my_configdir: "{{ansible_facts.distribution}}.configdir"

my_configfile: "{{ansible_facts.configfile}}.configfile"

    I want to do something similar to the following:

stat:

    path:  "{{my_configdir}}/{{my_configfile}}"

    register: result

 

    Unfortunately, path is being resolved to "myos.configdir/myos.configfile", not the expected "/path/to/directory/filename".  I have tried using various methods of concatenating variables together, including trying the 'vars' lookup plugin, but I have not been able to work this out after two days of trying.  So, here I am, back at the well, looking for another answer.  Does anyone have any advice?

my_configdir: "{{ (lookup('vars' ansible_facts.distribution)).configdir }}"

And so on...

V/r,

As usual, the answer is simple. I was trying to trying to include ".configdir" inside of the lookup plugin call. And now that I am looking at a working solution, I can see how this works. I can be very obtuse sometimes.
Thanks again.

Seems perfect time to ask a question to me. You tried everything you could on your own. Life always looks easy after you are given the answer but by design is a struggle to get there :-)

Sometimes when you think life is kicking you in the ass, it's actually just moving you quickly to a better place.
