Complex dictionary access

Archives Ansible Project

I have a dictionary structure that looks like the following:

myservers:

DC1:

CORE: 10.10.10.20

DMZ: 10.10.20.20

DC2:

CORE: 10.10.10.30.20

DMZ: 10.10.10.40.20

DC3:

CORE: 10.10.50.20

DMZ: 10.10.60.20

DC4:

CORE: 10.10.70.20

DMZ: 10.10.80.20

And another dictionary that looks like the following:

location:

address: 10.10.10.10

dc: DC1

net: 10.10.10.0

bits: 24

zone: CORE

I want to do something like the following:

  • debug:

msg: “myserver = myservers[‘{{location.dc}}’][‘{{location.zone}}’]”

and get back the message:

myserver = 10.10.10.20

But instead, I get:

myserver = myservers[‘DC1’][‘CORE’]

I want to see the value stored at myservers[‘DC1’][‘CORE’], not the string “myservers[‘DC1’][‘CORE’]”.

I have tried " {{ myservers[‘{{location.dc}}’]['{{location.zone}}] }}", but YAML does not allow nested braces, so that fails. And I have tried many other variations, but they all fail too. I am stymied. How do I extract the information I want?

Hello.
Try use “{{myserver[location.dc][location.zone]}}”

I knew it was going to be simple, although I thought I tried that one too. But that got it.

Thanks!
