Nested variable

[David Villasmil]

Hello guys,

 I've got this set_fact:

hosted_zone_id: "{{ dns_results | json_query('HostedZones[?Name==`mydomain.com.`].[Id]') | regex_replace ('/hostedzone/', '') }}"

But i want to get the id from any of my domains, so i want to use a variable:

hosted_zone_name: "mydomain.com"

and do something like:

hosted_zone_id: "{{ dns_results | json_query('HostedZones[?Name==`{{ hosted_zone_name }}.`].[Id]') | regex_replace ('/hostedzone/', '') }}"

But it looks like nested variables like that doesn't work...

Any suggestions?

Thanks!

David

Solved!

  - set_fact:
      hosted_zone_id: "{{ dns_results | json_query('HostedZones[?Name==`(lookup('vars', hosted_zone_name)).`].[Id]') | regex_replace ('/hostedzone/', '') }}"

For future reference.

Thanks

David

Spoke too soon... That doesn't work either...

Try this

- set_fact:
    hosted_zone_id: "{{ dns_results | json_query('HostedZones[?Name==' ~ lookup('vars', hosted_zone_name) ~ '].[Id]') | regex_replace('/hostedzone/', '') }}"

You need to escape outside of the quoted arg of json_query and then run the lookup. Note I haven't tested this

Hey Jordan, 

Thanks for replying!

There were "`" missing, worked beautifully after that!

- set_fact:
      hosted_zone_id: "{{ dns_results | json_query('HostedZones[?Name==`' ~ hosted_zone_name ~ '.`].[Id]') | regex_replace('/hostedzone/', '') }}"

"~" escapes it, so there's no need to do a lookup, works nice

Thanks!

ahh yes I should have seen you just wanted a nested var, just an FYI ~ is similar to + but coerces the variable to a string so you don't have to do that yourself. Usually + works but ~ is safer.

Thanks
